What DocTools Pro is
DocTools Pro is a completely free, all-in-one workspace for documents and images that runs in your browser. Files are processed locally on your own device, so nothing is uploaded to a server. The site states there is no account registration, no file size limit, no data tracking, and support for offline use. You can merge and split PDFs and Word files, rearrange or rotate pages, add watermarks and page numbers, run OCR, and lock files with a password. On the image side it resizes, crops, compresses, converts formats, and removes backgrounds. It also converts across 20 file types. Developed by ConvertFlow Systems, it is built for everyday office and creative file work.

What to watch out for
The tool is free now, but terms can change, so check the site for updates before you depend on it. Because everything runs locally in the browser, you need a reasonably capable device, and very large batches may run slowly compared with a desktop app. Offline use is offered, but confirm which features work without a connection. Since files never leave your machine, keep your own backups, as there is no cloud copy. Test each conversion on one file before processing a full set to make sure the output looks right.
