Smallpdf Overview

Smallpdf is a well-known online PDF platform offering a suite of tools for PDF conversion, compression, editing, and signing. It includes a redaction tool as part of its Pro subscription, allowing users to search for and black out text in PDF documents.

Smallpdf's redaction tool supports search-and-redact patterns, which users can configure to find specific text or patterns like email addresses and phone numbers. The tool is easy to use and works entirely in the browser, with no installation required.

However, Smallpdf has notable limitations. The free tier is heavily restricted, allowing only 2-3 file operations per day. The redaction tool itself is limited to simple pattern matching — it lacks AI-powered contextual detection. And critically, Smallpdf only supports PDF files; it cannot redact Word or Excel documents natively.

Redactly Overview

Redactly is a purpose-built document redaction tool that goes beyond Smallpdf's PDF-only approach. While Smallpdf is a general PDF utility suite with redaction as one feature among many, Redactly is focused entirely on doing one thing extremely well: finding and removing sensitive data from documents.

Redactly's AI-powered detection engine understands context, not just patterns. It can identify names, addresses, account numbers, and other sensitive data that a simple regex search might miss. And because Redactly supports PDF, Word, and Excel, you can handle all your redaction needs in one place.

Redactly is the only free online redaction tool that supports PDF, Word, and Excel. The free plan includes 20 pages per month with PDF and Word redaction. The Pro plan at $19/month adds Excel, batch processing, audit logs, and redaction certificates. Unlike Smallpdf's free tier which limits daily usage, Redactly's free plan lets you use your 20-page monthly allowance however you like.

Feature Comparison

Here is a deeper look at how the two tools compare across key dimensions:

Format Support

Smallpdf is PDF-only. If you receive a Word document or Excel spreadsheet that needs redaction, you must first convert it to PDF using another Smallpdf tool (assuming you have conversions remaining in your free tier). Redactly handles all three formats natively.

AI Detection

Smallpdf uses regex-based pattern matching. You need to know what you are looking for and configure the patterns yourself. Redactly uses AI to understand document context, automatically detecting a wider range of sensitive data without manual configuration.

Privacy

Smallpdf uploads files to its servers for processing. Redactly processes documents locally where possible with only extracted text sent to AI for detection, providing stronger privacy guarantees for sensitive documents.

Pricing

Smallpdf Pro costs $9/month (billed annually at $108/year) or $12/month for monthly billing. It includes access to all Smallpdf tools but is still limited to PDF. Redactly is free for 20 pages/month with PDF and Word, and $19/month for everything including Excel.

FAQ

Is Smallpdf's redaction tool free?

Smallpdf offers a limited free tier with restricted usage, typically 2-3 files per day. Its redaction tool is part of the Pro subscription. Redactly offers a completely free plan with 20 pages per month for PDF and Word redaction, with no daily limits.

Does Smallpdf support Word and Excel redaction?

No. Smallpdf primarily focuses on PDF tools. While it offers PDF-to-Word and PDF-to-Excel conversion, it does not natively redact Word or Excel files. Redactly is the only free online redaction tool that supports PDF, Word, and Excel natively.

Does Smallpdf have AI-powered redaction?

Smallpdf's redaction is pattern-based and requires you to manually define search terms or patterns. It does not use AI for contextual detection. Redactly uses AI to automatically detect sensitive data including names, addresses, and account numbers without requiring predefined patterns.

Which tool is better for privacy-conscious users?

Both tools process files online, but Redactly has a stronger privacy model. Documents are processed locally where possible — only extracted text is sent to AI for detection, not the full document. Smallpdf uploads files to its servers for processing, which may be a concern for users handling sensitive documents.
