Where your file goes

This is the main difference. InkOut PDF processes the PDF in your browser. In our own test on 2026-10-20, opening, redacting and downloading a file sent no upload requests: the only network requests were for the site's own code.

Smallpdf describes uploading your file and processing it on its servers, with automatic deletion after one hour, although its redact page also mentions processing "100% in your browser." If it matters for your document, check Smallpdf's current documentation or ask Smallpdf which applies to the redaction tool.

Free limits and pricing

InkOut PDF is free for files up to 5 pages with manual boxes. Pro adds unlimited pages, keyword redaction and multiple files, for $4.99 as a 24-hour pass (one-time, no subscription) or $7.99 per month as Pro Monthly (renews monthly, cancel anytime). Smallpdf offers free use with limits and a Pro subscription with a 7-day free trial; see its pricing page for current prices in your region.

Output and checks

Both tools say they remove the content rather than cover it. InkOut PDF rebuilds each redacted page as an image, so text on those pages can't be selected or searched afterwards, and after export it scans the whole output file for the text you covered before you download. Whichever tool you use, search the final file for the redacted words, or run it through the free redaction checker.

When to choose Smallpdf

  • You want one subscription for many PDF tasks: converting, compressing, editing, signing.
  • You work across devices. Smallpdf says its tool works on Mac, Windows, Linux, iOS and Android.
  • You're comfortable with your file being processed under Smallpdf's security and deletion policies.

When to choose InkOut PDF

  • You mainly need redaction and want the file to stay on your device.
  • You want an automatic check of the export before you download it.
  • You need a one-off job and prefer a 24-hour pass to a subscription.
