Convert PNG to JPG
Convert a PNG to a JPG to make a photograph much smaller. This is the right move when a photo got saved as a huge PNG — but the wrong move for screenshots and logos, and it can’t keep transparency. It runs entirely in your browser.
Your images never leave this device, and every file is built in your browser.

80% is a good balance of size and clarity.
PNG can contain transparency, and JPG can’t. Any see-through areas will be flattened onto a white background.

Why convert PNG to JPG?
The good case: a photograph saved as PNG is needlessly enormous. Re-saving it as JPG can cut the size dramatically with no visible difference, which is perfect for emailing or uploading.
The bad case: if the PNG is a screenshot, a diagram or anything with text and hard edges, JPG will actually look worse — its compression smears sharp edges — and can even end up bigger. And JPG has no transparency, so any see-through areas get flattened onto a solid background.
What you gain
- Dramatically smaller for photographs
- Universally supported for sharing and upload
What you lose or trade
- Transparency is lost — see-through areas are flattened onto a background colour
- Lossy — introduces artefacts, worst on text and sharp edges
- For screenshots/graphics it can look worse AND be larger than the PNG
The honest recommendation
If your PNG is a screenshot or has text, converting to JPG will make it look worse and can even be bigger — keep the PNG (or use our format advisor to check before you commit).
Measure it on your own image with the format advisor →PNG to JPG: questions
Does PNG to JPG keep transparency?
No — JPG can’t store transparency. Any transparent areas are flattened onto a solid background when converting. If you need the transparency, keep the PNG or convert to WebP instead.
Will my image look worse as a JPG?
For a photograph, not visibly at high quality. For a screenshot, logo or anything with text and hard edges, yes — JPG smears those, and it can even produce a larger file. Our format advisor measures both so you can decide.
Why would a JPG be bigger than the PNG?
For flat, few-colour images (screenshots, graphics), a palette PNG is extremely efficient, while JPG spends bytes trying to encode the sharp edges it’s bad at. In those cases JPG is both larger and lower quality.
