About CrabTools
Free PDF, QR and image utilities made with the same care as the software we deliver to our clients.
Who we are
CrabTools is a project by Crabsoft, a custom software studio. We built it because the most common free tools ask you to sign up, add watermarks, or upload your documents to servers you do not control.
How we protect your information
All processing happens in your browser. Your files never leave your device, we use no cookies or analytics, and fonts are served from this same site. You can read the details in the privacy policy.
What you will find
Merge and split PDFs, compress documents, create WiFi QR codes with a logo, convert images, remove backgrounds and vectorize. We keep growing the catalog and the languages.
Need something custom?
If your business needs a system, an app, automations or AI agents, Crabsoft builds it with you.
