Free PNG to JPG Converter
Turn one or many PNG files into JPG photos with a quality you choose. Transparent areas are flattened onto white, and everything happens in your browser.

Convert one or many at once to JPG · processed in your browser, never uploaded
Higher = better quality and larger file. 80–92% suits most photos.
Runs entirely in your browser — your images are never uploaded to a server.
Quick answer
To convert PNG to JPG, re-encode the picture in the JPEG format, which uses lossy compression to make a much smaller file. This tool does it in your browser: drop in one or more PNGs, set the quality, and download JPGs. Because JPG has no transparency, any see-through areas are placed on a white background.
Formula & method
The tool decodes each PNG, paints it onto an HTML canvas — first filling the canvas white so transparent pixels don't turn black — then exports the canvas as JPEG at the quality you set. JPEG drops fine detail the eye barely notices, so a screenshot or logo saved as PNG usually shrinks dramatically when re-saved as JPG.
Examples
- Input
- 1.8 MB PNG screenshot → JPG 85%
- Result
- ≈ 320 KB
- Why
- Screenshots saved as PNG are large; JPG at 85% keeps them readable while cutting most of the size.
- Input
- Transparent PNG logo → JPG
- Result
- Logo on a white background
- Why
- JPG cannot store transparency, so the previously clear background becomes solid white.
- Input
- 12 PNG product shots at once
- Result
- 12 JPGs, one download each
- Why
- Drop the whole set in together and convert them in one pass instead of one at a time.
When to use this tool
- Shrinking a heavy PNG screenshot to attach to an email or upload form.
- Meeting a site that only accepts JPG/JPEG uploads.
- Turning a batch of PNG exports into smaller photos for the web.
Common mistakes
- Converting a logo or icon that needs a transparent background to JPG — it gains a solid white box; keep PNG or use WebP instead.
- Setting quality very low (under ~50%) on text-heavy screenshots, which makes letters blurry and blocky.
- Expecting JPG to be sharper than the PNG — JPG is lossy, so it can only match or slightly soften the original, never improve it.
Frequently asked questions
Are my PNG files uploaded to a server?
No. The conversion runs entirely in your browser using an HTML canvas, so your images never leave your device — safe for private or work files.
What happens to the transparent background?
JPG does not support transparency, so any transparent areas are filled with white. If you need to keep transparency, convert to WebP instead, which supports an alpha channel.
Why is JPG so much smaller than the PNG?
PNG is lossless and stores every pixel exactly, which is large for photos and screenshots. JPG uses lossy compression that discards detail you can barely see, producing a far smaller file.
Can I convert many PNGs at once?
Yes. Drop in or select several files and they are all converted to JPG together, with a one-click download for each and a Download-all button.
What quality setting should I pick?
80–92% is a good balance of clarity and size for most images. Use higher for detailed photos you'll print, and lower only for small web thumbnails.
Will converting reduce the image dimensions?
No — the pixel width and height stay the same. Only the file format and compression change. To change dimensions too, use the Image Resizer.
