Frequently Asked Questions

Are my images uploaded to a server?
No. Every image tool runs entirely in your browser using WebAssembly. Your files never leave your device — we literally cannot see them.
What image formats are supported?
We support all major web formats including JPG, PNG, WebP, GIF, SVG, AVIF, and HEIC. More formats are added regularly.
Is there a file-size limit?
There are no artificial limits. Since processing happens on your device, the only limit is your browser's available memory. Most modern devices handle images up to 50 MB without any issues.
Can I process multiple images at once?
Yes! Most of our image tools support batch processing. Just drop multiple files and they'll all be processed in parallel.
Do I need to create an account?
No sign-up, no account, no email required. Just open the tool and start working.
