MyPDFBoy vs Smallpdf for PDF Redaction: Which Actually Removes Your Data?

Smallpdf is one of the most popular PDF tools on the internet — around 50 million monthly visits, a clean interface, and a comprehensive feature set covering compression, conversion, signing, and editing. If you need to convert a Word document to PDF or compress a file to email, it is an excellent choice.

PDF redaction is different. The technical requirement — permanently removing content from the document's internal data structures — is one of the harder problems in PDF tooling. Most general-purpose PDF platforms, including Smallpdf, implement it as visual masking. That is a meaningful distinction if the reason you are redacting is to ensure information cannot be recovered.

This comparison covers both tools honestly. Smallpdf is better in several ways; MyPDFBoy is better at the specific task of true redaction.

What Each Tool Actually Does to Your PDF

Smallpdf Redaction

Smallpdf's redaction feature (available on their Pro plan at $12/month) draws a filled rectangle over the content you select. In the PDF file, this is stored as an annotation layer — a drawing element positioned above the original content.

The original text remains in the content stream underneath. Using pdftotext or any PDF text extractor on the output file will return the "redacted" content. In Adobe Reader, entering annotation edit mode may allow removal of the overlay rectangle.

Smallpdf is not alone in this approach. It is how the majority of general-purpose PDF editors implement their redaction features because it is significantly easier to build than true content removal.

MyPDFBoy Redaction

MyPDFBoy uses PyMuPDF on the backend to perform content stream redaction. When you apply redaction zones:

1. The backend parses each marked zone and identifies all text objects and image data within those coordinates
2. Those objects are removed from the content stream
3. A solid black rectangle is placed in the same position as a visual indicator
4. The modified PDF is returned to your browser

The original content no longer exists in the file. pdftotext returns nothing for the redacted regions. There is no annotation layer to remove. The information is gone, not hidden.

Feature Comparison

Feature	MyPDFBoy	Smallpdf
Redaction method	True content removal	Visual overlay (masking)
Text extractable after redaction	No	Yes
Annotation removable to reveal content	N/A	Yes (in some viewers)
Account required	No	Free tier: No; Pro: Yes
Price for redaction	Free	$12/month (Pro)
File size limit	Browser memory limit	5GB (Pro)
Other PDF tools	Redaction + watermark only	20+ tools (compress, convert, merge, sign, etc.)
File storage	None — processed in memory, not stored	Files stored 1 hour on free, longer on Pro
Upload to server	Yes (processed server-side, not stored)	Yes (stored on servers)
Browser-side processing	No	No
Verification method	Try to select text — nothing selects	N/A

Privacy Comparison

Smallpdf's privacy model: files are uploaded to their servers, processed, and stored temporarily (1 hour on free, until you delete on Pro). They use TLS in transit and AES encryption at rest. Their privacy policy covers GDPR compliance.

MyPDFBoy's privacy model: files are uploaded to the processing server, processed in memory, and the result is returned immediately. No file is written to disk. No copy is retained. No account exists, so there is no identity associated with any upload.

For most documents, either approach is fine. For documents that contain sensitive information — the kind of documents you are redacting — the distinction matters. Uploading a document containing SSNs, medical records, or legal strategy to a service that stores it for an hour is a risk most compliance frameworks would flag.

Neither model involves selling user data or using document content for purposes other than processing.

Pricing Comparison

	MyPDFBoy	Smallpdf
Redaction	Free	Pro only ($12/month or $108/year)
Access limit	None	2 free tasks/day on free tier
Account required	No	Required for Pro
File history	No	Yes (Pro)

Smallpdf's pricing is reasonable for teams that need a full PDF toolkit. If you need to merge, compress, convert, sign, and redact PDFs regularly, $12/month for a comprehensive platform is fair.

If you specifically need PDF redaction and privacy is a concern, paying $12/month for a tool that applies visual masking is worse value than using a free tool that performs true removal.

Where Smallpdf Is Better

To be direct: Smallpdf is a better product for most PDF tasks.

• Breadth: 20+ tools covering every common PDF operation
• Conversion quality: Word, Excel, and PowerPoint to PDF conversion is reliable
• Compression: Aggressive file size reduction without visible quality loss
• Signing: E-signature workflow with audit trail
• Team features: Shared workspaces, user management, usage tracking
• Support: Responsive customer support with a large user base and documentation

If you use PDFs in a professional context and need a general-purpose toolkit, Smallpdf Pro is a good subscription.

Where MyPDFBoy Is Better

For PDF redaction specifically:

• Redaction is true removal, not a visual overlay — the only thing that matters for genuine data protection
• No cost — redaction that actually works should not require a subscription
• No account or file storage — if the document contains sensitive data, the tool should not retain it
• Verifiable — every user can test the output themselves using text selection or pdftotext

The Bottom Line

If you need to redact a document and the information genuinely needs to be gone — legal filings, medical records, financial documents — use a tool that performs content stream removal. For that specific task, MyPDFBoy is the better choice.

If you need a comprehensive PDF platform for a team, Smallpdf Pro is worth considering — just use a different tool for anything that requires true redaction.
