About HTTP Status Codes

HTTP Status Codes is a free Becoderr tool. It needs no sign-up, runs fast and privately, and works right in your browser for most tasks. For the few server-based tools, your files are processed in memory and discarded immediately after the operation.

Frequently asked questions

Is this tool free to use?

Yes. Every tool on Becoderr is completely free with no sign-up required. Signed-in users get higher file-size limits.

Are my files safe?

Yes. Browser-based tools process files entirely on your device; nothing is uploaded. Server-based tools process files in memory and discard them immediately after the operation.

Is there a file size limit?

Server-based tools accept up to 5 MB for anonymous users and 50 MB when signed in. Browser-based tools are limited only by your device.

Do I need to install anything?

No. Becoderr runs entirely in your web browser on any device: Windows, macOS, Linux, Android or iOS.
