Frequently asked questions
Which format makes the smallest files?
AVIF usually gives the smallest files, followed by WebP and then JPG. PNG is lossless, so it is the largest for photos but best for logos, text and screenshots.
Which format works everywhere?
JPG (and PNG) open on every device and app. WebP and AVIF work in all modern browsers but some older programs can’t open them.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser, so your images never leave your device. It also works offline once the page has loaded.
Can I convert many images at once?
Yes. Drop as many images as you like – they are converted in parallel. Download them one by one or all together as a ZIP file.

Yes. There is no sign-up, no daily limit and no watermark on your downloads. The site is supported by ads.
Does it work on my phone?
