About Folio

What Folio is

Folio is a free PDF editor. You can edit text, sign, fill forms, highlight, redact, merge, split and convert PDFs without installing anything or creating an account.

How it works

Folio uses pdf.js to display your document and pdf-lib to write the edited file, both running on your own device. That is why your files are never uploaded, and why Folio works even on a slow connection once the page has loaded.

Limits worth knowing

• Editing existing text places new text over the old one. The replacement uses a standard font, so it may not match the original exactly.
• PDFs protected against editing are saved as images after you change them.
• Redacted pages are saved as images so the removed content cannot be recovered.

Who makes Folio

Folio is built and maintained by RIGGT (riggt.com). It is free to use, and your documents are never collected or stored.
