Comparison
PDF Redactor vs Adobe Acrobat: which redaction tool to use
Adobe Acrobat is the PDF standard, and Acrobat Pro can redact: mark text and areas, search for words and patterns, apply the redactions, then sanitize the file to take out hidden information. Redaction is one tool among dozens in a suite sold by subscription.
PDF Redactor only redacts, in your browser. It finds personal data for you, removes it from the file on every download, and checks the copy it saved. Nothing is uploaded, its AI included.
We make PDF Redactor. Everything below about Acrobat comes from Adobe’s website, plans page and Acrobat help pages as of 29 October 2026.
The short version
Redaction in Acrobat needs Acrobat Pro or Studio, from US$19.99 a month on an annual plan. In PDF Redactor, finding, marking and removing are free on every PDF. Both can use AI to find names and both can read scanned pages, but Acrobat’s AI redaction goes through AI Assistant on Adobe’s servers, while PDF Redactor’s Local AI and Scanned text run on your computer. Every Pro feature is free on your first 3 PDF downloads. Acrobat is the better choice for redacting many files the same way, or if you already use it to edit, fill and sign PDFs.
What PDF Redactor adds
Redaction is free on every PDF
Finding emails, phone numbers, card numbers, US Social Security numbers and IBANs, Find words, Draw box, Select text, Hide all, and the black box, blurred and white-out looks are all free, with no watermark and no file limit. Acrobat Standard doesn’t include redaction, so you need Pro or Studio.
Pro features (Local AI, label boxes and Scanned text) are free on your first 3 PDF downloads, with no account and no card. After that, everything above stays free.
Suggestions as soon as the file opens
In Acrobat, you choose a pattern in Find text and redact and run the search. PDF Redactor looks for every format as soon as you open the file and shows each match as a dashed box. Hide one with a click or the H key, or every one at once with Hide all. Card numbers are checked with the card checksum, so random 16-digit numbers aren’t flagged.
No Apply step to forget
In Acrobat, marked text is removed when you select Apply, and hidden information when you continue to sanitize. PDF Redactor has no separate step: every download removes the text under each box, and Remove hidden info, on by default, takes out the author, metadata, comments, attachments, scripts and bookmarks. You get a new copy, and your original isn’t changed.
The saved file is checked
After saving, PDF Redactor reopens the new copy and searches it for every word you removed. A page that fails is rebuilt as a flat image with the boxes burned in, then checked again. Earlier versions saved inside the file are dropped, so an old revision can’t bring anything back. Adobe’s redaction guide doesn’t describe a check of the saved file.
AI that stays on your computer (Pro)
Acrobat’s AI Assistant can redact by meaning: ask it to remove names, Social Security numbers or account numbers, and it highlights each match for you to accept. Adobe says it processes documents “using Adobe’s secure infrastructure”, and lists it with Acrobat Studio or an AI Assistant add-on. PDF Redactor’s Local AI finds names, street addresses, account numbers and passwords on your own computer, after a one-time download of about 810 MB. It needs a browser and graphics card with WebGPU, and works best on English.
Scanned pages, read on your computer (Pro)
Scanned text reads the text in scanned pages and images on your computer, so emails, numbers and the words you search for are found there too. Each match it finds in a scan carries a scan icon, so you know to check it. It reads printed English. Acrobat Pro turns scans into searchable PDFs that you then search and redact. In both, you can also cover anything on a scan by hand; PDF Redactor’s Draw box is free.
No account, nothing uploaded
PDF Redactor needs no account and keeps working offline. Its only network requests are the optional Local AI model download and the Pro license check, and neither includes your documents. Acrobat plans come with an Adobe account.
Where Acrobat is the better choice
- Many files, same rules. Adobe points to the Action Wizard in Acrobat Pro to speed up redaction you repeat. PDF Redactor works on one PDF at a time for now; batch redaction is coming soon.
- A full PDF editor. If you also edit text, fill and sign forms, or compare and export PDFs, Acrobat does all of it. PDF Redactor only redacts.
- Other languages. AI Assistant supports a dozen languages. PDF Redactor’s Local AI and Scanned text work best on English, though its pattern finders, Find words and Draw box work in any language.
- Phones and tablets. Acrobat has desktop, web and mobile apps. PDF Redactor runs in Chrome and Edge on a computer.

Which to choose
Choose PDF Redactor if you redact now and then and don’t want a subscription, you want personal data found for you, or your files must never leave your computer, AI included.
Choose Acrobat if you redact many files the same way, or you already pay for Acrobat and use its editing, forms and signing. When you do, always select Apply and sanitize before you share the file.
