Frequently asked questions
Are my files uploaded to a server?
No. Every tool on NeedToConvert runs inside your browser. The file is read from your device, converted in memory and offered back as a download. Your files are never transmitted.
Is it really free?
Yes. There are no paid tiers, daily limits or watermarks. The site is supported by unobtrusive ads and voluntary Buy Me a Coffee donations.
Do I need to create an account?
No. Open a tool, drop a file and download the result.
Does it work on my phone?
Yes. All tools work in modern mobile browsers. Very large files may be slow on older phones because conversion uses your device's memory.
