Direct text editing

Click a supported text block and type directly on the page. Short replacements retain natural character proportions, and longer replacements wrap without matching the original word count. Toggle Wrap for a single expanding line; Shift+Enter inserts a manual line break. The original font is reused where possible, with a matching fallback for missing Latin characters. Scanned text requires OCR first.

Rich annotation and drawing toolkit

Annotate PDF files with yellow, green, blue or pink text highlights, freehand drawing pen lines, rectangles, circles, arrows and customizable sticky notes.

Full page management with thumbnail sidebar

Reorganize PDF documents using the left page thumbnail sidebar. Rotate pages 90 degrees, delete unwanted pages, adjust page order, and insert blank pages.

Complete client-side privacy and export

All PDF rendering, text editing and document generation run locally in client-side JavaScript memory. No document content is uploaded to external cloud servers.
