Convert PNG to JPG
PNG files are often five to ten times larger than they need to be. Converting to JPG is how you get a photo down to a sane size — and how you get past an upload form that only accepts JPG. It happens right here in your browser; nothing is sent anywhere.

PNG is a lossless format. Every pixel is stored exactly, which is wonderful for logos, screenshots of text and anything with a transparent background. It is a poor fit for photographs: a photo saved as PNG can easily be 8 MB where the same photo as JPG is 800 KB and looks the same to your eye.
The reasons this comes up in practice are nearly always one of these:
- An upload form rejects it. Job portals, government forms, school systems and older webshops often accept JPG only.
- The file is too big to email or send. A handful of PNG screenshots will blow through a 10 MB attachment limit; as JPG they usually fit with room to spare.
- A page loads slowly. Photographs served as PNG are one of the most common causes of a heavy web page.
- Storage is filling up. Screenshots pile up fast, and on most phones and laptops they land as PNG.
How to convert
- Drop your PNG files onto the converter. You can select a whole batch at once.
- Leave the output on JPG.
- Set the quality. 90% is the default and is visually indistinguishable from the original for almost any photo; drop to 75–80% if you need the file smaller still.
- Download them one at a time, or press Download all.
What changes when you convert
Transparency disappears. This is the one thing to know. JPG has no alpha channel, so any transparent area has to become a solid colour — we fill it with white, which is what you want in almost every case (a logo dropped onto a white page, a product cutout for a marketplace listing). If you need the transparency to survive, keep it as PNG, or convert to WEBP, which supports both transparency and heavy compression.
Compression becomes lossy. JPG throws away detail your eye is unlikely to notice. On photographs this is invisible at high quality. On screenshots of text, on sharp-edged diagrams and on flat-colour graphics it is more noticeable: you may see faint smudging around letters. For those, PNG is genuinely the better format and converting is the wrong move.
Nothing else moves. The dimensions stay the same; we do not resize, crop or re-colour anything.
PNG or JPG — which should you keep?
- Photographs, camera shots, anything with gradients: JPG. Far smaller, no visible loss.
- Logos, icons, anything needing a transparent background: PNG.
- Screenshots that are mostly text or UI: PNG keeps the text crisp. If size matters more than crispness, JPG at 90% is a reasonable trade.
- Images for a website you control: WEBP beats both on size and still does transparency.
Common questions
Will converting back to PNG restore the quality? No. Once JPG has discarded detail it is gone; saving that JPG as a PNG again just produces a large file holding the reduced detail. Always convert from your original.
Is there a limit on how many I can do? No cap and no watermark. Because the work happens on your own machine, a very large batch of very large images is limited only by your device's memory.
Does it work on a phone? Yes. It runs in the mobile browser exactly as it does on a desktop.
Questions
Does converting PNG to JPG lose quality?
JPG compression is lossy, so some detail is discarded — but at the default 90% quality that loss is invisible on photographs. It is more noticeable on screenshots of text and sharp-edged graphics, where PNG remains the better choice.
What happens to a transparent background?
JPG has no transparency, so transparent areas are filled with white during conversion. If you need the transparency to survive, keep the file as PNG or convert it to WEBP instead, which supports both transparency and strong compression.
Are my images uploaded to a server?
No. The conversion runs entirely inside your browser, so the images never leave your device. There is nothing for us to store or delete.
How much smaller will the JPG be?
For photographs, typically five to ten times smaller. For flat graphics and screenshots the saving is much less, and occasionally a JPG of a simple graphic is even larger than the PNG was.
