UAIP Yet Another PDF Editor

UAIP Yet Another PDF Editor puts a PDF viewer and editor on your pages. Visitors can read a PDF, mark it up, sign it or fill it in, and download their own copy, all in the browser. Every feature is free: there is no premium version, no locked settings and no upgrade notices.

Flipbook

• Show any PDF from your Media Library as a book with turning pages: magazines, brochures, catalogues, menus, yearbooks. No account and no conversion service: the pages are drawn in the visitor’s browser from your own PDF.
• Turn pages by clicking, dragging a corner, swiping, or with the keyboard.
• Two-page spreads on wide screens, one page on phones.
• The first page as a cover, or pages paired from the start.
• Right-to-left books for Arabic, Hebrew, Jawi or manga.
• Show only the cover on the page; the flipbook opens in a lightbox when it is clicked.
• Thumbnail strip, page number box, download, print and full screen. Links in the PDF stay clickable.
• One click switches to the document viewer for search, zoom, annotating and signing.
• Follows the visitor’s “reduce motion” setting, and screen readers can read the page text.

Annotate and sign

• Highlight text in five colours.
• Draw freehand, in five colours and three sizes.
• Add text boxes and images.
• Sign: draw a signature with mouse, finger or pen, or type your name. Place, move and resize it anywhere on the page.
• Undo, redo and delete.
• Download saves everything into the visitor’s copy of the PDF. Nothing is uploaded to your site, so there is no personal data to store.
• Turn it off site-wide or per block if you only want a viewer.

Viewer

• Continuous scrolling with page numbers you can type in.
• Search inside the document, with all matches highlighted.
• Clickable links and a table of contents (outline).
• Thumbnails sidebar.
• Zoom: automatic, page width, page fit, actual size and percentages.
• Download, print and full screen buttons (each can be turned off).
• Text selection and copy.
• Visitors can fill in PDF forms and download the completed copy.
• Password-protected PDFs ask the visitor for the password.
• Keyboard shortcuts and screen-reader labels; works with keyboard only.
• Light, dark or automatic colours.

Fast pages

• Nothing loads on pages without a PDF.
• The viewer loads only when it scrolls into view, or when the visitor clicks “Load PDF” if you prefer.
• No jQuery. PDFs are read straight from your Media Library, so large files load page by page.
• Built on a current release of pdf.js (Mozilla’s PDF engine), which never runs JavaScript from inside a PDF.

Easy to use

• PDF Viewer block: upload or pick a PDF, then set the height, start page, zoom and toolbar buttons per block. The editor shows a live preview.
• PDF Flipbook block: the same block, shown as a book. Switch any PDF Viewer block between the two in its settings.
• Shortcode: [yape_pdf id="123"] or [yape_flipbook id="123"] for classic content, widgets and page builders.
• Turn a File block that links to a PDF into a PDF Viewer block in one click.
