Excise

Overview

Excise is a free, open-source PDF editor for Windows, macOS and Linux, with a command-line interface for batch work. It suits people who want everyday PDF tools alongside content-removing redaction and ways to check for leaks. Its practical appeal is that redaction changes the document content rather than merely hiding it; its scope is not a fit for specialized print or JavaScript workflows.

Key features

Redaction and audit

Excise removes redacted text, images and vector graphics from PDF content streams instead of laying a black box over them. It also scrubs metadata, attachments, JavaScript, thumbnails and hidden layers by default, and reports what it removes. That combination is useful when disclosure risk matters, though redaction should not be treated as a substitute for checking the resulting file: the CLI's unredact command tests for surviving redacted text, while audit looks for text hidden beneath opaque overlays.

PDF work and forms

For routine document handling, Excise supports viewing, search, text selection and copying, annotations, page organization, Bates numbering and file-size reduction. It can fill and flatten AcroForms and create new form fields. OCR uses the system's Tesseract installation. These are a useful spread of workbench features, but Excise does not offer text editing or PDF conversion, so it is not a full replacement for software centered on rewriting document text or changing formats.

Automation and security

The command-line tool supports batch workflows and stable JSON output, which makes Excise more practical for repeatable processing than a desktop-only editor. The repository also includes managed-code PDF core and rendering libraries, an Avalonia viewer control and a C ABI over Excise.Core for other languages. It reads and writes AES-128 and AES-256 encryption, and inspects digital signatures against the operating system trust store. Signature inspection does not check certificate revocation or evaluate timestamp and long-term validation material, so it is not a basis for certificate-authority trust decisions.

Pricing

Excise's Open source plan costs nothing and is MIT licensed. No paid tiers are stated, so there is no cheaper tier that trades away features or a paid upgrade to budget for. The price makes it an appealing option for individuals and teams seeking a no-cost PDF workbench, but the available facts do not establish seat allowances, quotas or a support service.

Platforms

Excise supports Windows, macOS and Linux, with self-contained packages for Apple Silicon macOS, Windows 10/11 x64, Ubuntu/Debian and x64 or ARM64 Linux. Its OCR integration relies on system Tesseract. Release builds are not signed or notarized and do not auto-update; SHA-256 files are provided for verifying release assets.

Who it's for

Excise is best suited to people who need regular PDF viewing, annotation, page organization or AcroForm handling, and especially to those who want redaction that removes content with CLI checks for common leak paths. Its batch workflows and libraries also make it relevant to developers integrating PDF processing. It is the wrong choice for dynamic XFA forms: those layouts are experimental, may omit or move content, and cannot be filled in Excise. It also disclaims prepress, color-managed print production, JavaScript workflows and portfolio workflows, so users whose documents depend on those capabilities should look elsewhere.

Pros and cons

• Pro: Redaction removes underlying content and scrubs several related hidden-data sources, rather than relying on a visual cover-up.
• Pro: CLI audit commands and batch workflows give security-conscious users and developers ways to check files and automate repeat work.
• Pro: The free MIT-licensed plan includes everyday editing, annotations, forms and encryption support without a stated paid tier.
• Con: XFA fields cannot be filled, and experimental XFA rendering may omit or reposition content.
• Con: Signature checks omit revocation and long-term validation checks, limiting their value for high-assurance trust decisions.
• Con: Unsigned, unnotarized builds and no auto-update require users to verify and manage releases themselves; specialized print and JavaScript workflows are outside its scope.

Alternatives

Document Redaction Software and PDF editors are useful category pages for comparing more options.

• LocalRedact is another free option, with an AGPL-3.0-only Python package and optional local HTTP service; consider it if that packaging better suits your workflow.
• GroupDocs.Redaction is a paid option with a free plan and trial across desktop, mobile, web and self-hosted platforms; consider it if you need a broader platform range.
• Philter offers free personal, non-commercial and evaluation use with on-device redaction; consider it for that specific use case.
• BleachPDF is free, runs on your own computer and supports Linux and macOS; consider it if those platforms and local execution fit your needs.
• Docuflair Redact is a paid, cross-platform option with a free trial; consider it if you prefer a trial before committing to a paid tool.
• PineThink Redact has a free single-document personal-use plan and a paid tier at $6.99 a month after a 14-day free trial; consider it for occasional personal redaction or if you want a trial-based upgrade path.
• PDFRedaction is a web option whose free plan allows 10 documents per day for registered users, with local processing, OCR and image redaction; consider it if browser access and that daily allowance suit you.
• Redact PDF AI offers prepaid credits and a freemium model; consider it if a credit-based option fits your usage.

Verdict

Choose Excise if you want a no-cost, cross-platform PDF workbench whose redaction removes content and includes CLI checks for leaks. The combination of everyday PDF tools, automation and auditing is its strongest reason to choose it. Look elsewhere for fillable XFA forms, signature validation that checks revocation and long-term material, or specialized print and JavaScript work.
