PNG to JPG
Turn PNG images into smaller JPG files, with your choice of background for any transparent areas.
Your files never leave your device

PNG images, one or many. Or drag them anywhere on this page.
Opened on this device. Nothing is uploaded.
Transparent areas of the PNG are filled with this colour.
Up to 50 images per batch, 50 MB each, about 100 megapixels each. PNG in; other formats (WebP, GIF, BMP, AVIF) are accepted too.
How to convert PNG to JPG
- Choose your PNG files, or drag them onto the page.
- Pick the colour that fills transparent areas (white suits most uses) and set the quality. 85 to 90 is a good default for photos.
- Press Convert, then download each JPG or all of them as a .zip.
When to turn a PNG into a JPG
PNG keeps every pixel exactly, which is ideal for screenshots, logos and diagrams but wasteful for photographs: a phone photo saved as PNG can be ten times the size of the same photo as JPG. Converting such images to JPG makes them quick to email, upload to a form with a size cap, or put on a web page.
JPG gets its small size by discarding fine detail the eye is unlikely to miss, and the quality slider decides how much is discarded. It cannot store transparency, so the tool composites the image over a solid colour first. The pixel dimensions do not change; only the way they are stored does.
Tips
- If the image is text, a chart or a logo, keep it as PNG, or shrink the PNG with Compress image instead.
- Still too large? Reduce the pixel dimensions with Resize image before converting.
- Going the other way? Use JPG to PNG.
Questions
What happens to the transparent parts of my PNG?
JPG has no transparency, so every transparent or partly transparent pixel is blended onto the background colour you choose. Soft edges, such as a logo's anti-aliasing or a drop shadow, are blended too, so pick the colour of the page the image will sit on to avoid a halo.
Will the JPG always be smaller than the PNG?
For photos and screenshots of photos, usually by a lot, often five to ten times. For flat graphics with a few colours, text or line art, a PNG can already be small and the JPG may come out similar or even larger, with fuzzy edges around text. Those are better left as PNG.
What quality should I pick?
Around 85 to 90 looks the same as the original to most people at a fraction of the size. Go lower (70 to 80) for thumbnails and email, higher (95 and up) only when the image will be edited again. Quality 100 still compresses and is rarely worth the extra bytes.
Are my PNG files uploaded?
No. Your browser decodes each PNG and encodes the JPG on your device; the files are not sent to a server.
Is anything else changed?
The pixel size stays the same. Text chunks and colour metadata stored in the PNG are not carried over, so a PNG tagged with a wide-gamut colour profile may look slightly less saturated as JPG.
