How to use Image Converter

Can I convert iPhone HEIC photos?

Yes. HEIC files are decoded right in your browser — the decoder loads the first time you use it.

What happens to transparency when converting to JPG?

JPG has no transparency, so transparent areas are filled with the background color you choose.

Is Image Converter free?

Yes. Image Converter is completely free, with no sign-up, no watermark and no usage limits.

Is my data uploaded to a server?

No. Image Converter runs entirely in your browser. Your files and text never leave your device.

Does it work offline?

Yes. After Red Cat Tools has loaded once, this tool keeps working without an internet connection. You can also install Red Cat Tools as an app.
