JPG to PNG Converter
JPG dates back to 1992, named after the Joint Photographic Experts Group that designed it, and it remains the default format nearly every camera and phone saves photos in.

Switching a photo to PNG keeps every pixel exactly as it was the moment the conversion finished, which is the whole appeal for anyone about to edit it further. It gets small files by rounding off colour detail the eye is unlikely to notice, a trade called lossy compression, and every time a JPG is re-saved, it loses a little more, even if nothing was edited. Converting a JPG to PNG does not undo any of that: whatever detail the JPG already discarded stays gone, because a conversion can only work with what is there. What changes is what happens next. PNG is lossless, so from the moment of conversion onward nothing further is thrown away, no matter how many times the file is opened and saved again. The file also grows, often three to ten times larger, since PNG stores every pixel exactly rather than compressing it away. Converting does not add transparency on its own: a JPG's background is solid pixels, and PNG can only preserve what is already there, not invent a see-through area from nothing. PNG is worth choosing when a photo is about to go through several more rounds of editing, or as the container you need before a separate tool adds real transparency.
Every converter here is free, full size, no account. Photos convert in your browser and never leave it, except camera RAW files and SVG tracing. Those, like video, audio and e-books, need our server, and we delete them right after.
Everything happens inside this browser tab: the files never leave your device. Need another target format or a quality slider? Open the full converter.
Convert JPG to PNG โHow to convert JPG to PNG
- Drop your JPGs on the box above: one file or a whole folder's worth, JPG, JPEG or JFIF. On a phone, tap the box and pick them.
- Each JPG to PNG convert happens in your browser, lossless: converting each file to PNG takes a second or two, and the JPG file stays untouched.
- Save them one by one, or press Save all. Every PNG file keeps its original name, with .png on the end.

That's all there is to how to convert JPG to PNG format: PNG has no quality setting, so there's nothing to choose. The conversion runs in your own browser, so the files are never uploaded and there's no queue. This free JPG to PNG converter has no account, no watermark and no daily cap, so you can free convert JPG to PNG as often as you like and get a PNG free of watermarks every time. It's a PNG file converter and a JPG converter to PNG with one job, and it works as a batch converter as easily as a single-file one, so you can batch convert JPGs in one go. JPG and JPEG are the same format, so a JPEG to PNG converter is exactly this page too, and so is an online JPEG to PNG converter. To convert JPG file to PNG by the dozen, select them all at once.
It isn't limited to JPG. Any image the browser can read (WEBP, BMP, GIF) will turn into PNG the same way, so it doubles as an image to PNG converter: you can convert images to PNG in one batch, and convert image to PNG free as often as you like. Screenshots, scans, memes: as an image PNG converter and a PNG format converter it treats them all the same. Any photo converter can make a PNG; the point here is that it turns each photo into PNG without uploading it. Think of it as a file converter to PNG and a PNG converter, nothing more.

AVIF is the newer format some phones and apps save instead of JPG. It has its own page, AVIF to PNG, which explains what stays lossless and how transparency carries over.
Most sites that let you convert online JPG to PNG upload the file first, and some want an account before they process anything. This online JPG to PNG converter does neither. Every online convert JPG to PNG step stays local: you convert JPG to PNG online, but the work happens on your device.
Read this first: what PNG will and will not do
This is the important part, and it saves people a lot of frustration.
Converting does not make a transparent background. A JPG has no transparency, so its background is real, solid pixels. Saving it as a PNG simply stores those same pixels in a format that could hold transparency. The white behind your logo stays white. To actually cut a background out you need a tool that removes it, BGNinja does exactly that and hands you a transparent PNG.
Converting also does not make it scalable. A logo saved as JPG stays pixels no matter the container. If a printer or cutting machine asked for โa vector fileโ, what they want is an SVG, JPG to SVG traces your image into real, editable paths.
Converting does not restore lost quality. JPG discards detail when it saves. PNG is lossless, which means it preserves perfectly whatever you give it: including the compression artefacts already baked into the JPG. You get a bigger file holding the same imperfect image, not a better one.
The file will get considerably larger. Expect three to ten times the size for a photograph. That is the cost of storing every pixel exactly.
So a JPG to transparent PNG takes two steps: a background remover first, then PNG. BGNinja's is free and hands back a transparent PNG directly, so for most people it's the only step.
So when is JPG to PNG the right move?
Not every photo needs it, so here's when you actually want to change jpg to png rather than leave the file as it is:
- A tool or platform demands PNG. Plenty of print services, app-store listings, icon pipelines and design tools accept PNG only. This is the most common and most legitimate reason.
- You are about to edit repeatedly. Every time a JPG is re-saved it loses a little more. Convert to PNG first, do your editing rounds, and export to JPG once at the end.
- You are going to add transparency next. PNG is the container that can hold it, so converting is a sensible first step before you cut anything out.
- Sharp-edged graphics that started life as JPG. A diagram or screenshot saved as JPG will not get sharper, but PNG stops it degrading further.
What about WEBP?
If the destination is a website you control, WEBP is usually the better answer: it supports transparency like PNG, but at a fraction of the file size. Its only drawback is patchier support in desktop software. For anything going into print, a design tool or an app pipeline, stick with PNG.
Doing It the Other Way: PNG to JPG
The reverse job, shrinking a PNG down to a JPG, is a common reason people land here. This page only writes PNG. Need an image PNG to JPG, or any image to JPG? Our PNG to JPG converter does that, and it's a bulk PNG to JPG converter too. Select a whole folder to batch convert PNG to JPG in one go. You can convert PNG to JPG online free there, with no daily limit and nothing uploaded. A batch PNG to JPG run of hundreds of files, a real mass convert PNG to JPG job, is the same single step.
The quality slider does nothing here, and that's correct
Set the target to PNG and the quality control stops mattering: PNG compression is lossless, so there's no quality dial to turn. Every pixel that goes in comes out identical. What that means in practice is more useful than it sounds:
- The conversion adds nothing and removes nothing. A JPG that was already soft, blocky or full of compression artefacts produces a PNG of exactly that soft, blocky image: now stored perfectly. Converting to PNG cannot recover detail the JPG threw away years ago; there's nothing there to recover.
- It does stop the bleeding. JPG loses a little every time it's saved. Open, crop, save, open again, add text, save again: each round trip degrades what's left. This is called generation loss, and it's why a meme that's been through fifteen phones looks the way it does. Convert to PNG before a run of repeated edits and every save after that is free.
- Expect a bigger file. PNG is built for flat colour and sharp edges, not photographs. A photo saved as PNG is routinely three to five times the size of the JPG it came from, because lossless storage of millions of subtly different pixels is genuinely expensive. For a screenshot, a logo or a diagram the ratio is far friendlier, and sometimes PNG is smaller.
Transparency is something you add, not something you convert to
This is the single most common misunderstanding about this conversion, and it costs people a lot of time. PNG supports transparency; converting a JPG to PNG does not create any. A JPG cannot store transparency at all, so there was none in the file to begin with: the white area behind your logo is white pixels, and after the conversion it is exactly the same white pixels in a format that could, in principle, have held transparency instead.
If what you actually need is a logo or a product on a transparent background, the conversion is the wrong step. You need something that decides which pixels are subject and which are background and then deletes the background. See removing a background from an image. Convert to PNG afterwards if the tool hasn't already, because at that point the transparency is real and PNG is the format that keeps it.
Two related traps worth knowing: pasting a JPG into a design tool and deleting the white with a magic wand leaves a hard, jagged edge and white fringing around hair and soft edges, and saving a transparent image as JPG silently fills the transparency with white. One of the reasons a logo you were sure had a clear background keeps arriving on a white square.
Quick answers
Does the image change at all? No. Dimensions, colours and content are identical; only the container changes.
JPG JPEG PNG: which is which
Is a JPEG the same as a JPG? Yes, two spellings of the same file extension (Windows used to limit extensions to three letters). You never need to convert JPEG to JPG; a JFIF file is close enough to a JPEG to convert the same way.
The real difference between JPG and PNG isn't visible on screen at first: both look identical. It's what happens on every future save that changes. Turning a JPG into PNG stops that loss; it doesn't undo what's already gone.

Questions
Will converting a JPG to PNG give it a transparent background?
No. A JPG's background is made of solid pixels, and converting only changes the container, not the content. PNG can hold transparency, but converting does not create it. To actually remove a background you need a background-removal tool such as BGNinja.
Does converting JPG to PNG improve the quality?
No. PNG is lossless, so it preserves exactly what you give it: including the compression artefacts already present in the JPG. You end up with a larger file containing the same image, not a better one.
Why is the PNG so much bigger than the JPG?
PNG stores every pixel exactly instead of discarding detail the eye is unlikely to notice. For a photograph that typically means a file three to ten times larger.
When is it actually worth converting to PNG?
When a tool or platform accepts PNG only, when you are about to make several rounds of edits and do not want repeated JPG loss, or when PNG is the container you need before adding transparency.
Can I convert PNG to JPG here?
That is the reverse direction. Use our PNG to JPG page for that.
Is this JPG to PNG converter free?
Yes: no account, no watermark, no daily limit and no per-file cap. Like any free converter that runs in your browser, it costs us nothing, because your device does the work.
Can I convert a JPG image to PNG without losing quality?
PNG is lossless, so your JPG's existing detail is preserved exactly. The JPG's original compression artefacts are carried over unchanged: converting does not undo them, but it adds no new loss.
How to change JPG to PNG on a phone, Windows or a Mac?
Open this page in Safari, Chrome or Edge, drop the JPG in (or tap the box on a phone and pick the photos) and save the PNG; there are no settings to pick, and it works the same on every device. That one step is how to change JPG to PNG, on a phone or a laptop, a JPEG included. It is also how to convert JPG to PNG file by file, and how to turn a JPG into a PNG on a laptop. It handles several at once. Spanish, Portuguese and Italian write it as "JPG a PNG" or "JPEG a PNG"; same box. How to transfer JPG to PNG is the same thing: nothing is transferred, the image is rewritten as a PNG and lands in your downloads. Without this page, Paint on Windows (File, Save as, PNG picture) or Preview on a Mac can do one image at a time.
How do I get a PNG with a transparent background?
Not from this conversion alone: a JPG never stored any transparent pixels, so converting can't make the PNG delete background pixels by itself, and a JPG to PNG transparent background needs a background remover first. BGNinja is a PNG background remover free of charge: it cuts the background out and hands back a PNG with a transparent background directly. Converting only changes the format; a background tool has to remove the background, deciding which pixels go, before it can make the background transparent. After that you can convert JPG to PNG file formats here if the result is not a PNG yet.
Is a converter online JPG to PNG safe for private photos?
This online converter JPG to PNG never receives them: the conversion happens in your browser, so the photos stay on your device from start to finish.
How does this compare to CloudConvert or iLoveIMG?
CloudConvert JPG to PNG, CloudConvert PNG to JPG and iLoveIMG (both directions) upload your file to their servers. This one works in your browser, and the result is the same lossless PNG.
How to convert JPG to PNG on Windows or a Mac?
Drop the JPG onto the box above, wait a second, and save the PNG. There are no settings to pick along the way.
What's the difference between JPG and PNG?
JPG is lossy and smaller, with no transparency. PNG is lossless: every pixel stays exact, and can hold a transparent background, at the cost of a much bigger file for an ordinary photo.
Is it a batch converter?
Yes: batch convert JPG to PNG by selecting them together. As a JPG to PNG batch converter it keeps the names. Batch convert JPG photos from a folder. Going the other way, a PNG to JPG batch converter is the same box with JPG picked; convert PNG image to JPG there. From JPG to PNG or back, from JPG and PNG to WEBP too. As a PNG converter online it runs locally.
What about the JPG to PNG extension?
The JPG to PNG extension change is not enough: renaming a .jpg to .png doesn't convert it, and some apps refuse the file. Convert it here instead.
How to convert JPG to PNG transparent: background first or format first?
Remove the background first with BGNinja, which hands back a PNG directly. Changing only the format wraps the same solid background in a PNG, so nothing becomes transparent.
