JPG to PNG
Convert JPEG photos to PNG for lossless editing.

What this jpg to png does
JPG to PNG re-encodes a JPEG image into a PNG file without adding further compression loss. The conversion does not restore detail that JPEG discarded when it was created, but it prevents the new file from losing more quality as it is edited and saved again.
PNG files are normally larger than JPEG for photographs because PNG is lossless. That is a fair trade when you need an editable master, a format a particular tool accepts, or a file that will be processed repeatedly. For web delivery, WebP is usually a better compromise.
Why use it
- Edit and re-save an image repeatedly without compounding JPEG artefacts.
- Satisfy a platform that requires PNG uploads.
- Create a stable master file before applying filters or annotations.
How to use it
- 1Load one or more JPEG files.
- 2Check the original dimensions.
- 3Press Convert — PNG output uses the same resolution.
- 4Download the files.
Worked examples
Single photo
Input
portrait.jpg · 3000 × 2000
Output
portrait.png · 3000 × 2000 · larger file, lossless from here on
Common mistakes
- Expecting the converted PNG to look sharper; the lost detail cannot come back.
- Using PNG for large photo galleries, where the extra size slows page loads.
- Converting a CMYK JPEG from print work and assuming colour will be identical on screen.
Frequently asked questions
Does converting to PNG improve quality?
No. It preserves the current quality without further loss. Detail already discarded by JPEG compression stays gone.
Why is the PNG so much bigger?
PNG stores pixels losslessly. Photographs contain lots of subtle variation, which compresses poorly without loss.
