Frequently asked questions

Which conversions are supported?

Output: JPG, PNG and WebP. Input: anything your browser decodes — JPG, PNG, WebP, GIF, BMP, ICO, SVG and (on most modern browsers) AVIF.

Can I convert many images at once?

Yes. Drop them all, click Convert, and you get a zip with every converted file.

Are my files uploaded to a server?

No. Every iConvertDoc tool runs entirely in your browser using JavaScript. Files are opened on your own device, processed locally, and never transmitted anywhere — you can even go offline after the page loads.

Is this really free? Any limits or watermarks?

Completely free — no sign-up, no daily limits, no watermarks, no premium tier hiding features.
