Overview

ButDoc is a browser-based PDF and document toolkit for editing, converting, compressing, and managing files online. It combines PDF utilities with Word, spreadsheet, presentation, image, and text converters so users can handle common document workflows from one site.

The product is positioned for individuals, educators, businesses, and government teams that need to move between file formats, extract text from scanned PDFs, or make documents easier to share and store. The site emphasizes no installation, browser access on desktop and mobile devices, and automatic file deletion after processing.

Core features

Work with a broad set of document tasks in one browser-based toolkit, including edit, sign, merge, split, compress, convert, watermark, repair, redact, and crop operations.

OCR for scanned documents

Use OCR to turn scanned PDFs and image-based documents into searchable text, with support for 95+ languages and a Tesseract-based recognition workflow.

Compression and repair tools

Reduce PDF file size for email and web sharing, or repair damaged PDFs when files are corrupted or hard to open.

Browser-based document editing

Edit, annotate, sign, add page numbers, watermark, encrypt, unlock, flatten, and redact documents directly in the browser without installing desktop software.

Cross-device online workflow

Process files on any desktop or mobile browser, with uploads encrypted in transit and automatic deletion after processing.

File format conversion

PDF compression and sharing
Compress large PDFs for emailing, web upload, or storage when reducing file size matters more than preserving every original byte.
