JPG to PNG Converter
PNG is lossless, so once an image is in PNG it stops degrading every time it is saved. Convert JPGs to PNG when an image is going into an editing workflow, or when a tool or platform specifically requires PNG.

Or paste with Ctrl+V (Cmd+V on a Mac). Accepts PNG, JPG, JFIF, WebP, AVIF, HEIC, GIF and BMP. Nothing is uploaded.
How to convert JPG to PNG
- Add your JPGs. Drop in one image or a batch of them.
- Convert. PNG is lossless, so there is no quality setting to choose: the PNG stores exactly what your browser decoded from the JPG.
- Download. Save the converted images individually or as one ZIP.
JPG and PNG compared
| Feature | JPG | PNG |
|---|---|---|
| Transparency | No | Yes, full alpha channel |
| Animation | No | Only as APNG; most editors show one frame |
| Compression | Lossy | Lossless |
| Typical file size | Small for photos; text and sharp edges compress badly | Large for photos, compact for flat graphics |
| Support | Universal | Universal |
| Best for | Photos, email, upload forms | Screenshots, logos, images you will edit |
Things worth knowing
- Converting to PNG does not restore detail already lost to JPG compression. It preserves exactly what is in the JPG, no more.
- PNG files are usually larger than the JPG they came from, often several times so for photographs. That is the cost of being lossless.
- Converting will not add transparency. The image has no transparent areas to recover; you would need to erase a background in an editor.
Questions people ask
Are my images uploaded anywhere?
No. Your browser decodes and re-encodes each image on your own device, so there is no server to upload to and nothing is stored. The page does fetch extra code from this site the first time you use certain features (the ZIP download, PDF output, a WebP encoder for browsers without one, and the HEIC decoder), but your images are never part of those requests.
Will converting to PNG improve my image quality?
No. JPG compression discards information permanently, and PNG simply stores what remains without losing anything further. It stops the degradation but cannot reverse it.
Why is the PNG so much bigger?
PNG is lossless, so photographic detail that JPG approximates cheaply has to be stored exactly. Three to five times the size is normal for photographs.
When should I actually use PNG?
When an image will be edited and re-saved repeatedly, when you need transparency, or when it contains sharp-edged content like text, screenshots and diagrams.
