Frequently asked questions

Is this image converter free?

Yes, it is completely free with no sign-up, no watermark and no limits on how many images you convert.

Are my images uploaded to a server?

No. All conversion happens locally in your browser, so your images never leave your device and nothing is sent to us.

Which formats are supported?

You can convert between PNG, JPG, WebP and AVIF. PNG and WebP keep transparency, while JPG always uses a solid background.

Can I convert many images at once?

Yes, drop in a whole batch and convert them all to the same format in one go, then download them together.

Does converting to JPG or WebP reduce quality?

JPG, WebP and AVIF are lossy, so lower quality settings shrink the file but soften detail. PNG stays lossless. Pick a quality level that fits your needs.

Why are AVIF conversions slower or sometimes failing?

AVIF encoding is heavier than other formats. Very large images or low-memory phones can be slow or run out of memory, so try smaller files or a different format if it stalls.

Does it work offline?

Once the page has loaded in your browser, conversions run locally and continue to work without an internet connection.
