Common Questions

You can process up to 100 images simultaneously in a single batch. All processing is done locally, so it depends on your device speed.

Since processing is local, there is no server-side limit. However, we recommend files under 50MB for the smoothest browser experience.

We support JPG, PNG, WebP, AVIF, HEIC, BMP, and TIFF for input. New formats are added regularly.

No, Free Images Convert is 100% free for personal and commercial use. We are supported by community donations.
