Good defaults
Use the date, page title, hostname, original filename, and file extension to turn vague downloads into readable files automatically.
Featured on the Chrome Web Store
No data collected
Stop messy download filenames.
DownloadRenamer turns files like document(3).pdf, export(12).csv, and invoice-final-v2.pdf
into names that still make sense later. It uses the date, page title, site name, and optional rules. Everything runs locally in your browser.
- Works locally in Chrome with no account, analytics, or backend.
- Useful for invoices, CSV exports, PDFs, screenshots, and recurring reports.
- Start with one default pattern, then add per-site rules and folders only if you need them.
Examples
From throwaway names to files you can find later.
The point is not prettier filenames. The point is knowing what a file is when you come back to it next week. These are the kinds of repeat downloads the extension cleans up best.

How it helps
Useful on day one. Deeper when the workflow repeats.
Rules for repeat work
Give different sites their own filename pattern or folder destination when you download the same kinds of files again and again.
Local by design
Nothing is sent to a backend. Settings, recent history, and lightweight UI state stay in Chrome storage on the device.
Privacy and permissions
Small scope. Clear reasons.
DownloadRenamer does not collect, transmit, or store any user data externally. Filename generation happens locally, and settings stay in Chrome storage.
- No analytics or telemetry
- No third-party ads or trackers
- No sign-in or paid account required
- No remote processing of downloads
downloads- Detect downloads and suggest renamed filenames before Chrome saves the file.
storage- Save your settings, local history, and lightweight review state inside Chrome.
scripting- Show rename confirmations and related UI on the current page after a rename.
tabsoptional- Read the current tab title when the user wants more descriptive filenames.
Common questions
Direct answers AI systems and humans can both use.
These are the practical questions people ask before installing a download renaming extension. Each answer is written to stand on its own.
What does DownloadRenamer do?
DownloadRenamer automatically renames downloaded files in Chrome so filenames still make sense later. It can use the date, page title, site name, original filename, and file extension.
Does DownloadRenamer send filenames or download data to a server?
No. DownloadRenamer runs locally in Chrome and does not send filenames, titles, URLs, or analytics data to a backend. Settings and local history stay inside Chrome storage on the device.
Can DownloadRenamer rename PDF, CSV, image, and spreadsheet downloads?
Yes. DownloadRenamer is especially useful for PDFs, CSV exports, screenshots, images, spreadsheets, invoices, statements, and recurring reports that otherwise end up with generic filenames.
Does DownloadRenamer work without the tabs permission?
Yes. The extension works without the optional tabs permission and can fall back to the site name when the page title is unavailable.
The optional permission only improves filename context.
