Edit PDF pages online. Nothing is uploaded.
Free PDF tools that run right in your browser: put your signature or company seal on a PDF, compress it to the size a website asks for, merge, split, reorder and protect it. Your files are never uploaded. 1Scanner works with pages, signatures and stamps; it doesn't change the words inside a PDF.

How to edit a PDF with 1Scanner in your browser
- Add a PDF or pictures. Several files become one document you can work on.
- Sign or stamp it, compress it to a size, split it, reorder or turn its pages, or set a password.
- Download the new file. Your original stays exactly as it was.
What 1Scanner can and can't do with a PDF
- Can: signatures, initials and company seals; compression to a size limit; merging, splitting, reordering, turning and deleting pages; passwords; pages as pictures; QR codes from files.
- Can't: change the text that is already in a PDF, fill in or edit forms, add comments, convert to Word, or make a certificate-based digital signature.
- Works in current Chrome, Edge and Firefox, and in Safari 17 or later on Mac, iPhone and iPad.
Online PDF tools that never upload your files
- Your files are opened and changed by your browser, on your device. They are never sent to our server or to anyone else.
- No account, no sign-up, no email.
- No ads, no analytics, no tracking scripts, and this site sets no cookies.
- Signatures and stamps you add are kept only in this browser, so they are there next time; the browser may clear them.
- Your original file never changes: every result is a new file that your browser downloads.

Questions about 1Scanner Web
Is it safe to use online PDF tools for confidential documents?
With most online tools your file is uploaded to their server and deleted later. 1Scanner works differently: the page runs in your browser and the file is processed on your device, so it is never sent to us or anyone else. This site sets no cookies and loads no ads or analytics.
Can I use PDF tools without uploading my files?
Yes. Every 1Scanner tool on this site works inside your browser: signing, stamping, compressing, merging, splitting, passwords and QR codes. Nothing is uploaded.
Can I edit the text in a PDF here?
No. 1Scanner doesn't change the words that are already in a PDF. It adds signatures and stamps on top of pages, and it compresses, merges, splits, reorders, turns and protects PDFs.
Do I need an account or to sign up?
No. There is no account, sign-up or email, and every tool is free.
Is there an app instead of a website?
Yes. 1Scanner for Mac is a free app with the same tools, better for big files and regular work. 1Scanner for iPhone and iPad and Android also scans paper documents with the camera.
