Sign, fill and annotate PDFs, privately, in your browser
Quire PDF opens your file right here in this page. Highlights, notes, form filling, signatures and page changes all happen on your own device, and the PDF is never uploaded to a server.
When you are done, save an edited copy. Your original file is left as it was.

Questions
Plain answers
What this tool does, and what it does not.
Is my PDF uploaded anywhere?
No. The page and its PDF engine (Mozilla’s PDF.js) load from quireapps.com, and after that your file is opened, edited and saved inside your browser tab. The file is never sent to a server, and there is no analytics or tracking on this page. You can check this yourself in your browser’s developer tools under Network.
Is it free? Do I need an account?
It is free, with no account, no sign-up, no watermark and no daily limit. Files can be up to 100 MB.
What can I do with it?
Read and search, browse thumbnails and the outline, highlight text, add notes and text boxes, draw, place images, add a typed or drawn signature, and fill in existing form fields. You can also reorder and delete pages, combine several PDFs, and export selected pages as a new file.
Does Quire keep a copy of my file?
No. The document exists only in the open tab. If you close or reload the tab, unsaved edits are gone, so use Save a copy when you are done. The only things the page stores in your browser are your light or dark theme choice and, if you tick “Save signature”, the signatures you chose to reuse.
Can I change the existing text in a PDF?
No. Quire adds things on top of the page: highlights, notes, new text boxes, drawings, images and signatures. It does not rewrite text that is already in the PDF.
What can’t it do?
No OCR, so scanned pages are not made searchable. No secure redaction: drawing a box over text does not remove the text underneath. No certificate-based digital signatures. No XFA forms. PDF scripts are switched off, so forms that rely on JavaScript calculations will not calculate.
Which browsers does it work in?
It is tested in Chromium-based browsers such as Chrome and Edge. It is built on PDF.js, which also runs in current Firefox and Safari, but those have had less testing here. In Chrome and Edge, Save a copy lets you pick where the file goes; in other browsers it downloads.
Is there a Chrome extension?
Yes. The Quire PDF extension has the same editor and also keeps local recovery copies and a document library in your browser profile. It is free on the Chrome Web Store.
