DocTools Pro

DocTools Pro is a free, browser-based workspace for common document and image tasks. You can convert files between 20+ formats — including PDF, DOCX, JPG, PNG, and CSV — without uploading anything to a server. The tool also lets you merge, split, rotate, watermark, compress, and OCR PDFs and Word documents. For images, it handles resizing, cropping, background removal, and encryption. You can even password-protect any file type, from documents to videos, entirely in your browser.

Everything runs locally on your device using your browser's processing power. There is no installation, no account creation, and no file size limit. Once the page loads, most tools work even without an internet connection. Your files never leave your computer — they stay in browser memory and are gone when you close the tab. The site also tracks nothing: no analytics, no IP logging, no cookies beyond a simple counter to manage fair use.

DocTools Pro is best for anyone who needs quick document or image edits but wants to keep their files private. It is especially useful for people handling sensitive documents, working on the go with spotty internet, or just tired of signing up for yet another online service. Students, freelancers, and office workers will find the most use in everyday tasks like converting a Word file to PDF, splitting a large document into chapters, or compressing images for email attachments.
