File names are the first index most people use. A folder of
scan001.pdf files is technically searchable and practically
useless. Rename can take text from the document and put it in the filename,
so the name describes the content.
Step by step
-
1
Upload your PDF
Drag your PDF onto the box or click Choose file. It is sent over an encrypted connection and only used for this task.
-
2
Set the options
Adjust name pattern. Every field has a sensible default, so you can usually run the tool straight away.

Run it and download
Press Rename and the page shows progress while it works. When it finishes you get a download link — nothing is emailed and nothing is stored longer than it needs to be.
Pick text that identifies the document
Use a client name, invoice number or reference that appears consistently on the page. The pattern uses a text token from the document; the exact field or region should be stable across files. Check the first and last file in a batch: a name that works for one invoice may pick up a header from the next.
Patterns and safe characters
Keep the pattern short and avoid characters that operating systems reserve, such as slashes or colons. A date or reference prefix sorts a folder predictably; a person’s name makes it easy to find. Do not include sensitive identifiers in a name that will be shared outside the organisation.
Check for collisions
Download a batch and look for duplicate names. Two files with the same text token will collide; add a counter or a date. Open one renamed file to confirm the name matches its contents. The original PDF is unchanged, so a wrong pattern can be re-run safely.
Good habits for Rename
- OCR runs in your browser, so scanned documents are never uploaded.
- Straighten the scan first — deskewed pages give noticeably better OCR.
- A 300 DPI scan is the sweet spot between accuracy and speed.
Common questions
Is this tool free?
Yes. Every tool on this site is free to use, with no sign-up, no watermark and no daily task limit.
Do I need to install anything?
No. The tools run in your browser and are processed by this server.
What happens to my files?
They are stored under an unguessable id and swept automatically after a couple of hours. Nothing is shared or indexed.
Does it work on a phone?
Yes. The page pickers and editors are built for touch, so dragging, rotating and selecting pages all work without a mouse.
What does Rename do exactly?
Sets the document title from the text on its first page.
Can I rename a scanned PDF?
Only if the text is available. Run OCR first so the extractor can read the page text, or use a manual name pattern.
Does renaming change the PDF contents?
No. It creates a new file name for the download; the document itself is unchanged.
What if two files get the same name?
Add a counter or date token to the pattern. Check the download list for collisions before filing the copies.
