Convert JPG to PNG
PNG is the lossless format: crisp edges, no compression smudging, and support for transparent backgrounds. Here is how to convert, and — just as usefully — when converting will not give you what you are hoping for.
Convert JPG to PNG →How to convert
- Drop your JPG files onto the converter.
- Set the output to PNG.
- Download each file, or grab the whole batch at once.
The conversion runs in your own browser using the built-in image engine, so the files are never uploaded and there is no queue to wait in.
Read this first: what PNG will and will not do
This is the honest 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 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 when is JPG to PNG the right move?
- 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.
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.
Common questions
Does the image change at all? No. Dimensions, colours and content are identical — only the container changes.
Is there a limit? No cap, no watermark, no sign-up. Convert as many as you like.
Can I convert the other way? Yes — PNG to JPG is the far more common direction, and it is the one that actually saves you space.
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.
