Frequently asked questions

Yes. You can open, mark up, edit and save PDFs without an account, a trial or a watermark.

No. Your files are opened and edited inside your browser. Nothing is sent to Inkfolio or to anyone else when you open, draw on, edit or save a document. See the privacy notice for the details.

Press Ctrl+S or choose Save. Inkfolio creates a new PDF with your markup built in, so it looks the same in any PDF reader. The original file is never changed. Your work is also autosaved in this browser, so you can pick up from the home screen under Recent files.

Ballpoint, fountain pen, calligraphy brush, pencil, marker and highlighter, plus an eraser (whole stroke or precise), shapes, text boxes, images and signatures. Pen pressure and tilt are used when your stylus supports them, and strokes are smoothed so handwriting stays clean.

Yes. With a stylus, the pen draws and your finger scrolls and pinch-zooms. If you prefer to draw with a finger, open the View options and switch on finger drawing. Pen eraser buttons are supported on devices that report them.

Choose Edit PDF text (shortcut X), click a line of text, type your change and click away. Inkfolio matches the font style and colour as closely as it can. Note that it covers the old text rather than removing it, so the original words remain inside the saved file. Do not use this to hide confidential information.

Scanned documents and photos of pages are pictures, so they contain no text to edit or search. Pages with unusual fonts may also look slightly different after editing. You can always add a text box on top instead.

Yes, you will be asked for the password, which is only used in your browser. Saving a protected file may not work, because the new copy is created without the original protection.

Yes. In the sidebar, drag page thumbnails to reorder them, right-click a page to rotate, duplicate or delete it, and use the buttons at the top of the panel to insert a blank page or pages from another PDF.

Recent files, autosaved markup, your saved signature and your preferences are stored in your browser on this device. Remove a file with the cross on its card on the home screen, or choose Clear all. Clearing your browser’s site data for this website removes everything.

The page needs an internet connection to load the first time. After that your documents never need the network, but there is no dedicated offline mode yet, so a fresh visit without a connection will not open.

Current versions of Chrome, Edge, Firefox and Safari. Stylus pressure and tilt depend on your browser and device. Very large or heavily illustrated PDFs may be slow on older machines.

Inkfolio places an image of your handwritten signature on the page. It is not a certified digital signature and does not verify identity. Whether it is accepted depends on the document and where you are, so check with the person asking for it.

We would love to hear it. Write to [email protected] and include your browser, device and, if you can, what you were doing when it happened. Please do not attach confidential documents.
