Portable Document Format (PDF) Read and Sign
PDR Sign is a free PDF reader for the Linux desktop. Documents open in a continuous, smoothly scrolling view with thumbnails, the outline, full-text search, text selection and printing, and it follows your light or dark theme.
Fill & Sign lets you complete forms without leaving the reader: type into form fields, add text, ticks, crosses, dots, lines and dates anywhere on the page, and place your signature, initials or a company stamp. Draw a signature with a touchpad or mouse, type it in a handwriting font, or clean up a phone photo of it on paper. Saved signatures and stamps stay on your computer.
Save keeps your entries editable in PDR Sign and visible in every PDF reader. Save signed copy writes a new file next to the original with everything locked into the pages, while the original stays unchanged for corrections.
PDR Sign is free and open source, with no ads, subscriptions or paywalled features. It is supported by donations.
