FAQ

Common questions

Are these tools really free?
Yes. Every tool is free, with no sign-up, no daily quota and no watermark added to your output. The site is supported by a small number of display ads.
Do my files get uploaded to a server?
No. Processing happens inside your browser using JavaScript and the HTML canvas element. Your files never leave your device.
Is there a file size limit?
There is no artificial limit. Because processing happens on your own device, the practical ceiling is your computer's memory.
Can I use the results commercially?
Yes — the files you process are yours. However, you must own the rights to the original images you upload.
