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 you can add as many rows as you need, each with its own find and replace text. Or upload a rules file, one rule per line:

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

Control each rule

• 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.

Automate it from the command line

For repeatable jobs, the same engine is open source and free to run locally:

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

It returns a report of which rules landed and which were skipped. See the pdfblah CLI on GitHub.
