Everything runs locally in your browser, so your images never leave your device.

Why convert images to another format?

Frequently asked questions

Will converting an image reduce its quality?

Lossy formats (like JPG or WebP) may show a slight reduction depending on the chosen quality level, but the tool aims to preserve as much detail as possible. PNG conversions remain lossless.

Can the converter keep transparency?

Yes — PNG and WebP can retain transparency. If you choose JPG as the output format, transparency is removed because the format does not support it.

Does it support batch conversion?

Absolutely. You can drop in multiple images and convert them all in one session, even to different sizes depending on the format.

Does this tool work on iPhone and Android?

Yes. The converter is fully mobile-friendly and runs quickly on all modern browsers without installing an app.

Can I use the converted files commercially?

Yes. This tool adds no watermarks or usage restrictions. You retain full ownership of all images you convert.
