Bulk find and replace in a PDF

Rebranding a document, swapping a name everywhere, or fixing the same typo on every page? You can apply many replacements to a PDF in one pass.

Many rules at once

On pdfblah.com add as many Replace steps as you need. From the command line, a rules file holds one rule per line:

Old Company Name | New Company Name | all
CONFIDENTIAL DRAFT | FINAL | ci
Jane Doe | John Smith | all word
Total | Sum | 2

Scope: replace the first match, every match (all), or the Nth match (a number).
Ignore case (ci): INVOICE matches invoice.
Whole word (word): "cat" will not match "category".
Page: limit a rule to one page (p2).
Leave the replacement empty to delete the text.

Alignment is detected for you, so right-aligned numbers stay flush after the change.

Run your rules

Same engine, same result. Pick one:

Online at pdfblah.com, nothing to install and free while we're testing.
Local app, the same tool on your own machine in your browser, free and private (your PDF never leaves your computer): pipx install pdfblah then pdfblah gui.
Command line, best for repeatable and bulk jobs:

pipx install pdfblah
pdfblah in.pdf out.pdf --rules rules.txt

The CLI returns a report of which rules landed and which were skipped. The local app and CLI are open source and free. See the pdfblah project on GitHub or the guide to running it locally.
