Overview
BentoPDF is a free, open-source PDF toolkit (Apache 2.0 licensed) that runs entirely in the browser. Instead of uploading files to a server, all processing — merging, converting, compressing, signing, and more — happens locally on the user's device, making it a privacy-first alternative to typical cloud PDF tools.
The project is built with Vite, TypeScript, and Tailwind CSS, and its source code is publicly available on GitHub for self-hosting or contribution.
Key Features
BentoPDF offers roughly 80 tools spanning organization (merge, split, extract, reorder, rotate, N-up), editing (a full PDF editor, page numbering, watermarking, headers/footers, cropping, form filling, annotation removal), conversion to and from PDF (images, Markdown, text, OCR), and security/optimization (compression, encryption/decryption, permission management, digital signatures, redaction, and metadata editing).
Platforms & Self-Hosting
Because all functionality runs client-side in the browser, BentoPDF works on any device with a modern browser — Windows, macOS, Linux, iOS, and Android — with no installation required. Organizations can also self-host their own instance, typically via a Docker image.
Key Features
Client-side processing — All PDF operations run locally in the browser; files are never uploaded to a server.
~80 PDF tools — Covers organization, editing, conversion, and security/optimization operations in one toolkit.
No file limits or watermarks — Use any tool without file-size caps, sign-ups, or output watermarks.
PDF editing and annotation — Edit page content, add page numbers, watermarks, headers/footers, and remove annotations.
Conversion to/from PDF — Convert images, Markdown, and text to PDF, or export PDFs to images and OCR text.
Security tools — Encrypt, decrypt, manage permissions, add digital signatures, and redact content.
Self-hosting via Docker — Run a private instance of BentoPDF using an official Docker image.
