Convert PNG to JPG
PNG files from screenshots and design exports are often far larger than they need to be. Converting to JPG shrinks photographs dramatically and produces a file that every device, form and email client accepts. Everything happens in your browser with nothing uploaded.

The right reasons to convert PNG to JPG
PNG is lossless and supports transparency, and neither of those properties is useful for a photograph that is about to be emailed, uploaded to a listing or posted on social media. JPG throws away detail the eye does not notice and produces files a fraction of the size. If the PNG is a photo, a render or a screenshot of a photo, converting it to JPG is almost always the right move.
The wrong reason is habit. Logos, icons, charts, line art and screenshots full of text look worse as JPG, because lossy compression smears the sharp edges that make those images legible. For those, keep PNG or use WebP at a high quality.
Transparency becomes white
This catches people out most often. A PNG logo on a transparent background converted to JPG comes out on a white rectangle. There is no way around it in JPG. If you need a small file that keeps transparency, use the PNG to WebP converter instead; WebP supports alpha and is still far smaller than PNG.
Choosing quality
| Source | Recommended quality | Notes |
|---|---|---|
| Photograph exported from an editor | 82 to 88 | Large saving, no visible change at normal size |
| 3D render or digital painting | 85 to 90 | Smooth gradients can band at lower settings |
| Screenshot of an app or a website | 90+ or keep PNG | Text is the first thing to suffer |
| Scanned document | 75 to 85 | Combine with a max width to shrink big scans |
What to expect from the file size
A 1,920 pixel wide PNG photograph is commonly 3 to 5 MB. As JPG at quality 85 it becomes around 300 to 500 KB. Add a maximum width of 1,600 and it drops further to 200 to 300 KB. That is the kind of saving that makes a slow website fast, or a "file too large" upload succeed.
A note on colour
PNG can store 16-bit-per-channel colour and embedded colour profiles; JPG stores 8 bits per channel and the converter outputs standard sRGB, which is what screens and browsers display. For everyday use this is exactly what you want. For colour-critical print work keep the PNG master and hand that to the printer.
Frequently asked questions
What happens to the transparent background?
JPG cannot store transparency, so transparent pixels are filled with white. If the transparency matters, keep the PNG or convert to WebP instead.
How much smaller will the JPG be?
For photographs, usually 80 to 95% smaller. For flat graphics with few colours the saving is smaller and JPG may make edges look slightly soft.
What quality setting should I use?
For general sharing, 80 to 85. For anything that will be printed or edited again, 90 to 95. Below 70 you will start to see artefacts around sharp edges and text.
Is JPG bad for screenshots?
Lossy compression blurs sharp text and creates ringing around edges. Screenshots with a lot of text are usually better kept as PNG, or converted to WebP at a high quality.
