Convert PNG to JPG
Turn PNG images into JPG files that are much smaller for photos and open anywhere. Transparent parts are filled with the colour you choose.
Drop a PNG image, or click to choose
Add several PNG files to convert them together. JPG, WebP and AVIF work too.
Need several changes to one photo? The Photo editor does crop, text, filters and blur together.
How to convert PNG to JPG
- Add your PNG files. JPG is already chosen, so each PNG is converted as soon as it opens. Add several at once if you like.
- Pick a fill and a quality. Transparent parts of the PNG become the fill colour, white unless you choose another. The quality starts at 92%, which looks the same as the original for photos.
- Download. One image saves as a JPG; several save together as one zip.
How much smaller the JPG gets
For photos, a lot. PNG stores every pixel exactly, which suits flat graphics but makes photos huge. JPG keeps what the eye notices and drops the rest. For a screenshot full of text, there is almost no saving, and JPG can leave faint smudges around letters.
| Image | PNG | JPG at 92% |
|---|---|---|
| Forest photo, 1920 × 1080 | 4.6 MB | 664 KB |
| Lake photo, 1920 × 1080 | 3.7 MB | 418 KB |
| Screenshot of text, 1920 × 1080 | 364 KB | 337 KB |

What happens to a transparent background
JPG has no transparency, so every see-through pixel needs a colour. The converter paints them with the fill you pick, white by default, before saving. A logo on a transparent background becomes a logo on a white square. If you need the transparency, keep the PNG, or choose WebP, which keeps transparency and is still much smaller than PNG for photos.
When to keep the PNG
- Screenshots of text, code or a user interface: the JPG is barely smaller and less crisp.
- Logos and icons that sit on coloured pages and need their transparent background.
- Files you will keep editing. Each JPG save loses a little detail, so edit the PNG and convert once at the end.
If the JPG is still too big for an upload, run it through Compress image with a KB target.
