How to convert an image
- Click the box above, or drag your image onto it. JPG, PNG and WebP all work.
- Pick the format to convert to — JPG for photos, PNG for sharp graphics, WebP for the smallest file.
- For JPG and WebP, set the quality with the slider. 0.90 is a good middle ground.
- Press Convert image, then download the result from the panel on the right.
Worked example — one photo in three formats
We saved the same photo-like 800 by 600 test image in three formats. As PNG it was 1,123.3 KB — PNG keeps every pixel, so a busy photo costs a lot. As JPG at quality 0.85 it was 183.2 KB, about six times smaller. As WebP at quality 0.85 it was 206.6 KB on this test image — close to JPG, and on many photos WebP comes out smaller still. The lesson is simple: PNG is for sharp graphics and logos, JPG and WebP are for photos.
Frequently asked questions
How do I convert a PNG to JPG for free?
Open this page, add your PNG, pick JPG, and press Convert image. The JPG downloads from the panel on the right. There is no account, no email, and no fee.
What is the difference between PNG, JPG and WebP?
PNG keeps every pixel exactly, so it is best for logos and sharp graphics, but photos come out big. JPG throws away a little fine detail to make photos much smaller. WebP is a newer format that is often smaller than JPG at the same quality.
Will converting to JPG lower the quality?
A little — JPG is a lossy format, so some fine detail goes. At quality 0.90, most photos look the same at normal size. Converting from JPG to PNG does not bring back detail that is already gone.
Can I convert a photo with a clear background?
JPG has no transparency, so a clear background becomes solid — usually white. If you need the clear background, convert to PNG or WebP instead.
Is my image uploaded anywhere?
No. The conversion runs fully in your browser with the built-in canvas. Your photo never travels over the internet.
Your files never leave your device. This tool runs fully in your browser. Your files are not uploaded to any server, not stored anywhere, and not seen by anyone else. Close the tab and they are gone.
