Convert JPG to PNG
Up to 3 files at once, 100 with Pro. Mixed formats are fine.
Converting JPG to PNG gives you a copy that loses nothing from this point on. It does not restore detail the JPG already threw away, and it does not create a transparent background; expect the file to grow five to ten times. Drop the JPG above and it converts in your browser, free and without an upload.
When converting JPG to PNG is the right call
This conversion is worth doing for two reasons and neither is the one people usually have in mind. The first is editing: PNG loses nothing on each save, so an image about to be cropped, adjusted and exported several times will not accumulate damage the way a JPG does. The second is compatibility — some design tools, print workflows and upload forms want PNG specifically, and there is no arguing with a form.
Converting JPG to PNG does not restore lost quality
The reason this conversion is often done and should not be is the word lossless. Converting a JPG to a PNG does not repair it. The detail your camera or your last export threw away is gone, and PNG simply stores the damaged picture very faithfully. If a better original exists anywhere — the camera roll, the original export, the file before it went through a messaging app — convert that instead.
It will not give you a transparent background either
PNG supports transparency; your JPG has none; the result is an opaque image in a format that could have held some. Cutting a background out is editing work, and no conversion does it. If that is what you came for, you need a background remover first and then a PNG to keep the result in.
Why the PNG comes out much larger
Five to ten times is ordinary for a photograph, because PNG is a poor fit for continuous tone — it compresses by finding repetition, and a photograph has almost none. If size matters and you only need the image to open somewhere, WebP does the same job at a fraction of the space and is read by every current browser.

JPG vs PNG: size against permanence
| JPG | PNG | |
|---|---|---|
| Full name | JPEG Image | Portable Network Graphics |
| File extension | .jpg, .jpeg, .jpe | .png |
| Media type | image/jpeg | image/png |
| Compression | Lossy — file size is bought with quality | Lossless — nothing is discarded |
- Quality
- Nothing is lost. The result holds exactly the same picture, text or data as the original.
- Where it runs
- This conversion runs inside your browser. Your file is never uploaded, and it works with the network disconnected.
JPG to PNG: what people get wrong
- Are my JPG files uploaded anywhere?
- No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.
- Does converting JPG to PNG improve the image quality?
- No. PNG is lossless from this point on, but the JPG already discarded detail and nothing recovers it. You are preserving what you have, not restoring what was lost.
- Does converting JPG to PNG give me a transparent background?
- No. PNG can hold transparency, but a JPG has none to carry over, so you get an opaque image in a format that supports transparency. Removing a background is editing, not converting, and no format change does it.
- Why is the PNG so much larger than the JPG?
- Because PNG stores photographs inefficiently — it was built for flat colour and sharp edges, not for continuous tone. Five to ten times the size is normal for a photograph and is not a sign that anything went wrong.
- When is converting JPG to PNG actually worth it?
- When the image is about to be edited and re-saved several times, because PNG loses nothing on each save; and when a specific tool, print workflow or upload form insists on PNG. Outside those two cases you are trading file size for nothing.
