How it works
Add your PNG files, pick a quality level, and each image is re-encoded as a JPG on your device. Transparent pixels are filled with the background colour you select, because JPG has no transparency.
It runs entirely in your browser, so nothing is uploaded.
Why convert PNG to JPG
PNG is lossless and ideal for graphics, but photographs saved as PNG are often several times larger than they need to be. Converting to JPG can shrink them dramatically with no visible quality loss.
JPG is also the safest choice for email, uploads and print workflows that don't handle PNG well.
Handling transparency
If your PNG has transparent areas, choose a background colour — white is the common default. Those areas will be filled with that colour in the JPG.
If you need to keep transparency, JPG isn't the right target format; keep the PNG or use the compressor instead.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
What happens to transparency?
JPG can't store transparency, so transparent pixels are filled with the background colour you pick before conversion. If transparency matters, keep the file as PNG.
Will the JPG be smaller than the PNG?
For photographs and detailed images, almost always — often by a large margin. For simple flat graphics with few colours, PNG can occasionally be smaller.
Can I convert several images at once?
Yes. Drop or select multiple files and they'll be processed in a controlled queue so your browser stays responsive. Each file shows its own progress, and you can download them individually or all together as a ZIP.
Is it free, and are there limits?
It's completely free with no account required. Because processing happens on your device, there's no per-file upload limit — the practical ceiling is your device's available memory. You can batch many files and download them as a single ZIP.
