Frequently asked questions
Is the image converter free?
Yes. No sign-up, no watermark, no limits.
Are my images uploaded?
No. Everything happens in your browser.
Can I convert to AVIF or HEIC?
Not yet. Browsers can read these formats but can't save them. WebP gives similar file savings and works everywhere.
