An offline PDF editor that keeps your files private
PDFLoom does its editing on your device. Install it once, and it opens, edits and saves PDFs with no internet connection and no upload. That makes it a secure, private PDF editor for sensitive documents.
Works without internet
After you install it, PDFLoom's editing tools work offline. AI features download their model the first time you use them, then run locally.
A PDF editor without upload
Your document is processed in your browser or desktop app. PDFLoom keeps no server-side copy of anything you open.
Install it your way
Add it from your browser (Chrome, Edge, Safari) with no download, or install the desktop app for Windows, macOS or Linux.
What does use a server
Only features you choose, such as signature requests, share links, published forms and cloud sync. Each is listed on the Trust page.
