Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Excise is an open-source PDF editor and pure-.NET PDF framework for desktop users and .NET developers. Its desktop application supports Windows, macOS, and Linux, while the codebase provides reusable parser, rendering, OCR, and viewer libraries under the MIT license. The feature set is aimed at technical document handling: users can view, search, copy text, organize pages, fill and author AcroForms, place flat typewriter text, create annotations, redact document content, inspect signatures, and work with attachments.

Its strongest fit is structured, repeatable PDF processing. Command-line batch workflows with JSON output give developers a way to automate document operations, while page insertion, extraction, removal, reordering, and rotation cover common document-management tasks. Glyph-level redaction is paired with metadata and attachment scrubbing, and OCR workflows use the system Tesseract CLI. These capabilities make Excise a practical choice for teams that value local tooling, scriptable operations, and access to .NET components rather than a hosted subscription workflow.

Excise is free and open source, with no paid tier structure described. The main boundary is editing depth: it adds flat typewriter text but does not edit existing PDF text. It also does not provide general PDF format conversion, so users who need broad conversion or direct modification of established text should choose a different PDF editor. Pick Excise for cross-platform forms, annotations, redaction, OCR, signature inspection, and batch JSON workflows; avoid it when full text editing or format conversion is central to the job.
