Why convert PNG to JPG
PNG is lossless and large. JPG is smaller and accepted nearly everywhere, which is why portals and email limits prefer it.
Convert with PicFitter
Open the PNG to JPG converter, pick one or several PNG files, and download each JPG. Everything runs in your browser.
What happens to transparency
JPG has no transparency, so transparent areas become white. If you need transparency, keep PNG or use WebP.
Convert without a tool
On Windows open the image in Paint and use Save as, JPEG. On Mac open it in Preview and choose File, Export, JPEG. On a phone, share the picture to an app that exports JPG, or use the online converter.
Checklist
Check the dimensions are unchanged, the background looks right, and the file size is lower than the PNG.
PNG or JPG: which one should you use?
| PNG | JPG | |
|---|---|---|
| Best for | Logos, screenshots, graphics, transparency | Photos, uploads, email, websites |
| Compression | Lossless (no quality loss) | Lossy (small quality loss) |
| Typical file size | Large for photos | Much smaller for photos |
| Transparency | Yes | No, becomes white |
| Accepted by forms | Sometimes | Almost always |
How to convert PNG to JPG on a phone
Open the PNG to JPG converter in your phone browser, tap to choose the PNG from your gallery or files, and save the JPG. Nothing is uploaded, so it also works well for private documents.
How to convert several PNG files at once
Select multiple files in the converter. Each file is converted separately in your browser and you download each JPG. Converting one at a time keeps memory use low on older phones and laptops.
What happens to a transparent background?
JPG cannot store transparency, so transparent areas are filled with white. If you need another background colour, use the background tool to place the subject on white, grey or black first, or keep the file as PNG.
Will the quality change?
Photos converted at high quality look almost identical. Screenshots with sharp text can show slight blur around letters at low quality. If a form also has a size limit, convert first and then use the 100KB or 200KB compressor.
Common problems and fixes
- The JPG has a black background. This happens in a few old apps. Convert with a browser tool that fills transparency with white.
- The JPG is bigger than the PNG. This is rare and happens with very simple graphics. Keep the PNG for those.
- A form rejects the file. Check the exact size and dimension limits; use the resizer if needed.
