Is Image Converter really free?

Yes. Image Converter is completely free to use. There is no premium version, no feature locked behind a paywall and no ads. The app is maintained thanks to voluntary donations from users who want to support the project.

Does my data ever leave my computer?

No. Every conversion happens locally on your machine. Your images and folders are never uploaded to a server, which makes the tool a safe choice when you work with client files or sensitive visuals.

Which image formats are supported?

Image Converter supports PNG, JPG, GIF and WebP, both as input and output, with more formats added regularly. Pick whichever format your project needs, WebP included when file size matters most.

Can I convert a whole folder at once?

Yes. You can select a single image or an entire folder tree. The original folder structure is preserved in the output, so your project stays organized exactly as before.

Which operating systems does it support?

Image Converter currently runs on Windows 10 and Windows 11 (64 bit). Support for other systems is being considered for future releases.
