The bigger picture: Documents
Visas, job applications, tenancy contracts and bank forms all run on PDFs. These tools merge, compress, sign and edit PDFs in your browser, so passports, IDs and statements never leave your device.
What's changing: As people grow more careful about where personal documents go, privacy-first, in-browser PDF tools are replacing upload-based websites.
Frequently asked questions
Can someone remove the watermark?
