All security operations happen locally in your browser for maximum privacy. No cloud uploads, no data retention - your documents stay completely confidential.

Complete security and compliance hub

All Secure PDF Tools

Open Fileza security, redaction, inspection, signing, timestamp, archive, accessibility, and compliance readiness tools from one updated hub.

Advanced Redaction

Search, mark, manually redact, sanitize, and report sensitive PDF content with review-first safety controls.

Hidden Text Remover

Find hidden text signals, remove metadata, strip annotations and attachments, and produce a cleanup report.

GDPR Document Cleanup Helper

Scan PDFs for personal-data patterns and prepare safer cleanup reports without claiming automatic compliance.

Sensitive-data Warning Scanner

Detect email, phone, card-like, ID-like, and custom sensitive terms before sharing a PDF.

Change Permissions

Set or change user permissions on a PDF.

Decrypt PDF

Unlock PDF by removing password protection.

Digital Signature PDF

Add a cryptographic digital signature to your PDF using X.509 certificates. Supports PKCS#12 (.pfx, .p12) and PEM formats. Your private key never leaves your browser.

Encrypt PDF

Lock your PDF by adding a password.

Remove Restrictions

Remove password protection and security restrictions associated with digitally signed PDF files.

Sanitize PDF

Remove metadata, annotations, scripts, and more.

Timestamp PDF

Add an RFC 3161 document timestamp to your PDF using a trusted Time Stamp Authority (TSA) server. Proves your document existed at a specific point in time. No certificate required.

Validate PDF Signature

Verify digital signatures in your PDF files. Check certificate validity, view signer details, and confirm document integrity. All processing happens in your browser.

Certificate-based Signing Workflow

Prepare a safe certificate-based signing workflow with signer intent, certificate inventory, timestamp policy, provider-readiness notes, and audit evidence.

Signed-document Audit Trail

Build a signed-document event timeline with document hash, signature signals, timestamp evidence, policy notes, and audit-chain readiness.

PDF Compliance Checker

Check signing, timestamp, metadata, permission, and workflow policy signals before sending PDFs through compliance-sensitive processes.

Signature Validation Report

Inspect PDF signature structure, ByteRange, SubFilter, signer details, DSS/LTV markers, and timestamp signals with conservative reporting.

Timestamp Evidence Report

Report DocTimeStamp, DSS/VRI, signed-date, TSA setting, OCSP/CRL, and long-term-validation evidence signals in signed PDFs.

PDF Malware-risk Scanner

Inspect PDFs for risky active-content signals, suspicious structures, external links, embedded files, forms, metadata exposure, and generate an explainable risk report.

Permission Inspector

Inspect PDF encryption, permission flags, copy/print/modify restrictions, and produce a clear permission report for sharing decisions.

Password Policy Checker

Review PDF encryption and password-policy signals, then generate a conservative report without exposing or cracking passwords.

Font Embedding Checker

Inspect PDF font embedding and subsetting signals so print, archive, and sharing workflows can detect font-risk issues early.

JavaScript/Action Inspector

Find PDF JavaScript, open actions, launch actions, additional actions, remote actions, and optionally create a safer stripped copy.

Attachment Risk Inspector

Detect embedded-file and attachment signals inside PDFs, report risky file references, and optionally strip reachable embedded-file structures.

External Link Inspector

Inspect PDF link annotations, URI actions, remote destinations, mail links, and suspicious schemes before sending or opening documents.

Metadata Exposure Report

Report PDF title, author, creator, producer, dates, XMP metadata, document IDs, and hidden exposure signals before public sharing.

PDF/UA Accessibility Checker

Inspect tagged PDF, reading order, language, title, and alt-text readiness for PDF/UA workflows without claiming certification.

PDF/A Deep Validator

Inspect PDF/A archive-readiness signals including metadata, output intent, fonts, encryption, attachments, and validator-adapter readiness.

Tagged PDF Inspector

Review StructTreeRoot, MarkInfo, ParentTree, RoleMap, and structure role signals in tagged PDFs.

Reading Order Inspector

Analyze page-by-page text extraction order, OCR needs, and reading-order warnings for accessible PDF review.

Alt Text Missing Report

Estimate image, Figure, Alt, and ActualText signals to find PDF image descriptions that need review.

Archive Readiness Report

Prepare a PDF archive-readiness report for metadata, output intent, fonts, active content, encryption, attachments, and links.

Why Use Fileza Secure PDF Tools?

Security tools for real PDF workflows

Encrypt, decrypt, change permissions, remove restrictions, sanitize files, validate signatures, timestamp PDFs, and run compliance-style checks from the same suite.

Careful privacy and retention controls

Security tools use browser-first processing where practical and follow admin-controlled retention and saved history rules when server-side or account-based features are used.

Signature and validation support

Digital signature, timestamp, PDF/A, PDF/X, and print-readiness workflows support business, compliance, archival, and prepress use cases beyond basic PDF editing.

Admin-controlled access

Security-sensitive tools can remain visible, restricted, monetized, or disabled through global tool defaults, enterprise tool settings, plan limits, and global monetization mode.

Frequently Asked Questions

Are these secure PDF tools free?

Fileza provides security tools for everyday use, but advanced checks, larger files, saved history, account-only access, API use, or premium workflows can depend on admin settings, credits, or plan rules.

Are my files private and secure?

Fileza uses browser-based processing for many PDF tasks and secure server-backed processing for heavier conversion or automation workflows when needed. Signed-in file history is optional and admin-controlled retention settings can limit how long processed files are kept.

Can I remove a PDF password?

Password removal and decryption require the correct access credentials or a file that can legally be unlocked. The tools are intended for documents you own or are authorized to modify.

Can I validate signed or compliant PDFs?

Yes. The suite includes signature validation, timestamping, PDF/A validation, PDF/X validation, and print-ready checks. These tools provide useful signals and reports, while legal or regulatory acceptance depends on your specific use case.

Do I need to install software?

No desktop software is required. Open the tool in your browser, upload or prepare the files you need, process the job, then download, share, or save the output when your current access level allows it.
