What it does

View & Navigate

High-quality bitmap rendering via PDFium. Page thumbnails, Ctrl+scroll zoom, and keyboard shortcuts for fast navigation.

Merge & Split

Combine multiple PDFs into one or extract selected pages into a new file. Drag-and-drop page reordering in the sidebar.

Edit Text

Double-click any line of text to edit it inline. Font matching from the original PDF preserves the look of the document.

Annotate

Text boxes, freehand drawing, and highlight overlays with customizable colors, sizes, and opacity. Undo and clear per page.

Signatures

Draw and save reusable signatures. Click to place them anywhere on a page, just like Acrobat. Signatures persist between sessions.

Search & Select

Ctrl+F full-text search with highlighted results. Drag-select to copy text, or Ctrl+A to grab the whole page.

Print

Print with annotations flattened into the output. Ctrl+P or toolbar button sends directly to the system print dialog.

Portable

Single exe, ~10 MB zipped. No installer, no admin rights, no config files. Drop it on a USB and go.
