How it works
Three simple steps to clean filenames
FileFIXR cleans up chaotic file names with a single prefix. Rename up to 20 files at a time—each up to 100MB—without ever leaving your browser.
Drop or select files
Drag them into the upload area or tap “Select files”. We support images, docs, audio, video, and more.
Add a prefix
Choose a naming pattern like “project-2024”. FileFIXR auto numbers everything in sequence.
Download instantly
Grab a single ZIP or individual files. Everything is renamed locally—no uploads, no waiting.
Privacy first
FileFIXR never uploads, stores, or scans your files. Renaming happens entirely inside your browser and the finished files go straight to your Downloads folder.
