FAQ

Frequently asked questions

How can a converter work without uploading my files?

Modern browsers can decode and re-encode images on their own, using Canvas, Web Workers, and WebAssembly codecs. ImageConverter ships those codecs to your browser instead of shipping your photos to a server — so the conversion happens on your machine. Open DevTools, watch the Network tab, and convert: nothing is sent.

Is this safe for private or sensitive photos?

Yes, and that is the reason it exists. Because files are never transmitted, there is no server copy to leak, no retention window, and no account tied to your images. This matters for ID documents, medical scans, and personal photos.

Does it work offline?

Once the page has loaded, yes. The conversion code runs locally, so you can drop the connection and keep converting.

What can I do here besides convert?

Compress to a target file size, resize, crop, rotate, flip, enlarge, and pick colours out of a photo. Every tool follows the same browser-only model.
