Rename PDF Online
Change a PDF file name in seconds, or rename a whole batch at once with sequential numbers, dates or suffixes. Free, no sign-up, and your files never leave your device.
Or choose them from your device. Nothing is uploaded — renaming happens in your browser.
Two files ended up with the same name, so a number was added to keep them apart.
Add your PDFs
Drag files onto the page or pick them from your device. Up to fifty at a time, on a phone or a desktop.
Choose how to name them
Type each name yourself, or let the tool number them, stamp today’s date, or add a suffix to the existing name.
Download
One file saves straight to your device; a batch arrives as a ZIP with every file already renamed.
Turn scan_0472.pdf into something you can actually find
Scanners, banking portals and messaging apps all hand you files named after their own internal counters. A folder of document(3).pdf and IMG_20260819.pdf is unsearchable, and the only way to know what is inside is to open each one.
Set a base name once and the whole batch is renamed together — numbered in order, stamped with today’s date, or given a suffix that keeps the original name intact. Every new name appears next to the old one before you commit, so you can see exactly what you are about to download.
Rename on a phone, and fix the title inside the file
Phones make renaming awkward. iOS hides the filename behind a long press in the Files app, and WhatsApp attachments often arrive with a name you cannot change before forwarding them. This tool works the same on a phone as on a laptop: tap, type, download.
There is a second name most tools ignore. Every PDF carries an internal title, and that is what a browser tab or a reader’s window bar displays — which is why a file you renamed to Invoice-2026.pdf can still open showing Microsoft Word – draft3. Tick the title option and both names are corrected together.

Open toolWhy renaming a PDF is more annoying than it should be
A filename is the only part of a document you can search without opening it, and almost nothing arrives with a useful one. Scanners produce scan_0472.pdf, banking portals produce statement(3).pdf, phones produce IMG_20260819_143022.pdf, and a shared drive turns all of it into a folder nobody can navigate. The fix takes three seconds per file — the problem is doing it three hundred times.
This PDF name changer solves both cases. Drop in a single file, type the name you want, and download it. Or drop in fifty, pick a naming rule, and get the whole set back as a ZIP with every file already correct. Nothing is uploaded to a server, nothing is stored, and no account is required.
Four ways to name a batch
Custom gives you a text box per file, so you can name each one exactly as you like — or type one name at the top and let it apply to everything, numbered automatically. Sequential puts a set in order: choose a base name, a starting number and how many digits, and you get report-01 through report-25, which sort correctly in every file manager. Date stamps today’s date in whichever format your filing system expects. Original + suffix keeps the existing filename and adds to the end, so signed, final or v2 can be applied across a folder without losing what each document already says.
On top of any mode you can add a prefix or suffix, change the letter case, and run a find-and-replace across every name at once — useful when a hundred files all contain the word “scan” and none of them should.
The other name inside every PDF
People often rename a file, open it, and find the old name still in the browser tab. PDFs carry an internal title in their metadata, separate from the filename on disk, and readers display that title when it exists — which is why a renamed invoice can still open as “Microsoft Word – untitled draft”. Tick the title option and the internal title is rewritten to match, so the document identifies itself correctly wherever it opens. Almost no free rename tool does this.
Why the file cannot be renamed on your computer
If Windows refuses to rename a PDF, the usual cause is that the file is still open — in Acrobat, in a browser tab, or in the Explorer preview pane. Close the reader, click away to release the preview, and try again. If it still refuses, the file may be read-only, mid-sync in a cloud folder, or somewhere your account cannot write to. On a Mac, a locked file shows a padlock in Get Info that has to be cleared first.
Renaming through this tool sidesteps all of that, because it never touches the original. It reads a copy in memory and hands you back a newly named download, leaving the file on your disk untouched.
Renaming on a phone
Phones are where this gets fiddly. On iPhone you have to save the PDF into the Files app, long-press it and choose Rename — attachments cannot be renamed inside Mail or WhatsApp. On Android it depends which file manager the manufacturer shipped. Because this tool runs in the browser, the steps are identical everywhere: open the page, add the file, type the name, download.
Naming conventions that stay readable in a year
Start with an ISO date, because 2026-08-20 sorts chronologically by default while 20-08-2026 does not. Follow it with the party or subject, then the document type, and keep the whole under about sixty characters. Use hyphens rather than spaces — spaces become %20 in links and sometimes break email attachments — and avoid the characters your operating system reserves, which this tool strips automatically.
Frequently asked questions
Add the PDF to the tool above, type the new name in the row that appears, and press download. The renamed copy saves to your device straight away, and the original file stays exactly where it was.
Almost always because the file is open somewhere — a reader, a browser tab, or the file manager’s preview pane — and the system has locked it. It can also be read-only, mid-sync in a cloud folder, or in a location your account cannot write to. Renaming here avoids the problem entirely, since the original is never modified.
That is the document title stored in the PDF’s metadata, and it is what browser tabs and reader window bars display. Open the advanced options and tick “Also change the document title inside the PDF” — the title is rewritten to match your new filename when you download.
Yes — up to fifty files per batch. Choose sequential numbering, a date stamp or a suffix and every file is renamed together, then downloaded as a single ZIP. You can still edit any individual name before saving.
Open this page in your phone’s browser, tap to choose the PDF from Files or Downloads, type the new name and tap download. No app is needed, and it works the same on iPhone and Android.
No. The pages, text, images, quality and file size are all untouched — only the name changes. The one exception is the optional title setting, which rewrites a single metadata field and leaves the pages themselves alone.
Free, with no account, no watermark and no limit on how often you use it. Your PDFs are processed entirely inside your browser and are never uploaded, which matters when the documents are contracts, statements or medical records.
