FAQ
Questions, answered.
Yes. Every tool is free and there is no account to create.
Limits depend on the tool and your device. Everyday files such as photos, documents and short clips work well; very large videos are limited mainly by your device’s memory.
A recent version of Chrome or Edge gives the best video and audio support, including saving large exports directly to disk. Other modern browsers work for most tools.
Use the language menu in the top bar. Your choice is saved in this browser and used on every page until you change it.
