Is 图片格式转换 free? Do I need to register?

Most local tools work without registration. Some server-based functions require sign-in and have free usage quotas; check the tool page.

Do I need to install anything to use 图片格式转换?

No installation needed. Open the web page and use directly. Works in all modern browsers (Chrome, Edge, Firefox, Safari) on both desktop and mobile.

Is my data safe when using 图片格式转换?

Tools marked "browser-local / no upload" process your files entirely on your device. Server-side tools (e.g., PDF conversion) retain and clean up files according to the policy and expiry shown on the tool page.

Are there daily usage limits on 图片格式转换?

Most pure-frontend tools are unlimited. Tools that consume server resources (format conversion, OCR) have a free daily quota; logging in gives you a higher quota. Check "Remaining today" at the top of the tool page for details.
