JPG to PNG: when PNG is the better choice
PNG is lossless: every time you save it, nothing more is lost. Converting a JPG to PNG doesn't bring back detail the JPG already dropped, but it stops further loss when you edit and save again, and gives you a format that accepts transparency. Expect a larger file.
Key facts
- PNG is lossless; JPG loses a little detail every time it is saved.
- A PNG of a photo is usually several times larger than the JPG.
- PNG supports transparency, so you can remove the background later.
- Up to 20 MB and 50 megapixels per image, converted in your browser.

Why convert JPG to PNG?
JPG (JPEG) is the classic format for photos. Its lossy compression keeps files small, but it has no transparency and slightly softens sharp edges and text.
PNG is a lossless image format: every pixel is stored exactly, and it supports full transparency. It is the standard for screenshots, logos, icons and graphics with text.
Choose PNG when you need sharp text and edges, transparency, or an exact copy of every pixel.

Good to know
- PNG keeps the picture exactly as it is, but it can't bring back detail that JPG compression already removed, and the file is usually larger.
Questions about converting JPG to PNG
Does converting JPG to PNG improve quality?
No. Detail that JPG compression removed can't be restored. What PNG gives you is no further loss from now on, plus support for transparency.
Why is my PNG so much bigger than the JPG?
PNG stores every pixel exactly, while JPG throws away detail you rarely notice in photos. For photos, PNG files are often several times larger.
Will the PNG have a transparent background?
Not by itself: a JPG has no transparency, so the PNG keeps the same background. Once it is a PNG, you can remove the background in an editor.
Is the JPG to PNG converter free?
Yes. It is free, with no sign-up, no watermark and no limit on how many files you convert.
Is my file uploaded?
No. Your browser reads and converts the file on your own device; nothing is sent to 4Dev or anyone else.
Is there a size limit?
Images can be up to 20 MB and 50 megapixels, which covers photos from every current phone and camera.
Will I lose quality?
No new loss is added, because PNG is lossless. Detail that the JPG compression already removed does not come back, though.
