For the paperwork of everyday life

02Signing
Draw your signature, type it or use a photo of it. For official paperwork, sign with the certificate you already have in Windows, such as Spain’s FNMT, without installing anything else.
03Printing
Several pages per sheet, booklets ready to fold and posters across several sheets, with a preview that updates as you go.
And more
Edit the PDF’s own text and add text, images and shapes.
Highlight, underline, strike out, add notes or draw freehand.
Combine several PDFs, pull out pages, rotate them or change their order.
With phone photos or your scanner: it straightens the page and makes it look scanned.
Turn a scan into a PDF you can search and copy from.
Compress your PDFs so they’re easy to send by email.
From PDF to Word or images, and from photos to PDF.
Encrypt your PDFs so only people with the password can open them.
Strip metadata and photo locations before you share.
04Redaction
A black box on top isn’t enough: the text is still underneath and can be copied. Folio removes it from the file when you save.
Optional
Summarize a document or ask it anything: it answers with the page where each detail is. It’s off by default, and your documents aren’t uploaded anywhere.
Privacy
Payslips, contracts, a scan of your passport… Whatever you open with Folio never gets uploaded to a server. It doesn’t even ask you for an account.
Everything happens on your computer, even offline.
Each PDF opens in a Windows sandbox: a booby-trapped file can’t reach your other files or the internet.
Folio doesn’t keep track of what you do, and anyone can review its code.
Why Folio
PDF websites are convenient, but your documents usually pass through their servers. Paid apps do the job, but you have to pay for them.

No small print
There isn’t one. Folio is free software: its code is public, and anyone can use it, review it and share it. There’s no paid version, no ads, and it doesn’t make money from your data.
If you find it useful, the best way to help is to tell someone about it or give it a star on GitHub: that way more people find it.

Yes. There’s no paid version, no trial period, no ads and no watermarks on your documents. Folio is free software under the AGPL license: you can use it, copy it and share it without paying a thing.
No. You download it, install it and use it. Folio doesn’t ask for your email, a sign-up or a login.
No. Folio works on your computer and your PDFs never leave it. It only connects when it has to, such as to tell you about a new version or to timestamp a signature, which receives a fingerprint of the document and never the document itself. It’s all in the privacy policy.
Yes. Folio signs with the certificates installed in Windows, such as Spain’s FNMT. Signatures follow PAdES, the European standard for electronic signatures in PDF, and include a timestamp without you having to set anything up.
Yes. Take photos of the pages with your phone, copy them to your computer, and Folio finds the page in each photo, straightens it, removes the shadows and makes it look freshly scanned, with the text recognized so you can search it. It also scans directly with the scanners and multifunction printers installed in Windows, over USB or on your network.
Only if you want it to. It’s off by default, and if you turn it on it runs on your computer: it summarizes documents and answers your questions without uploading anything. It’s all explained in Folio’s AI.
Yes. You can open, fill in, edit, annotate, sign by hand and organize your PDFs offline, and use the AI once it’s downloaded. You only need the internet for the timestamp on a certificate signature, to check for new versions and to download the AI models, if you turn it on.
