Questions about these tools

Do these tools work on mobile?

Yes. Every tool runs in the browser, so it works the same on Android and iOS as it does on a desktop. Large batches simply take a little longer on a phone.

Is there a file size or usage limit?

There is no daily limit and no sign-up. Practical limits come from your device memory: up to 30 files per batch and roughly 50MB per image.

Which formats are supported?

You can open JPG, JPEG, PNG, WEBP, HEIC, HEIF, GIF, BMP and AVIF, and export as JPEG, PNG or WEBP. HEIC files from iPhone are decoded automatically in your browser.
