Frequently asked questions

Can it convert iPhone HEIC images?

Yes. HEIC files from iPhones are decoded in your browser and saved as JPG, PNG or WebP — no app and no upload required.

Are my photos uploaded to a server?

No. All conversion is client-side, so personal and sensitive images stay entirely on your computer.

What is the best format for the web?

WebP and AVIF give the smallest files at high quality; JPG is the safest choice for universal compatibility.

Toolbox uses the browser's native Canvas and codec APIs plus a maintained HEIC decoder, so conversions are accurate and keep pace with the formats modern phones and cameras produce.
