# Why can’t I upload my file?

Each tool has its own accepted formats and size limits. Check the tool page, then confirm that your file has a supported format and is within its limit. If it is too large, reduce its size or choose another suitable tool.

If the format appears correct but the upload still fails, try opening the original file on your device. A damaged or password-protected file may need to be repaired, unlocked, or exported again before processing. Retry in an updated browser with a stable connection. Keep the original file; EditChest creates a separate output and does not overwrite it.
