A lightweight, fast PDF viewer and editor for Windows. It edits the text that is already in a PDF, signs, redacts, recognizes scanned pages and organizes pages, and everything runs on your PC: no account, no uploads, no tracking.
Small: built with Tauri, so it uses the web engine that ships with Windows (WebView2) instead of bundling a browser like Electron apps do. The Store package is about 38 MB, most of it fonts for Chinese, Japanese and Korean and the text recognition models.
Rendering: pdf.js (Firefox's PDF engine). Editing and saving: pdf-lib.
13 languages: English, Turkish, German, Spanish, French, Italian, Polish, Portuguese (Brazil), Russian, Indonesian, Japanese, Korean and Chinese (Simplified). The system language is picked on first start. Light and dark themes.
Works with AI assistants: a built-in MCP server lets Claude Desktop and other MCP clients work with your PDFs on your PC.

## Features
### Viewing
Fast on-demand rendering: documents with hundreds of pages open instantly
Zoom (Ctrl + wheel, fit width or page), page navigation, thumbnails and bookmarks panel
Search (Turkish İ/ı aware), select and copy text
Links (internal links jump to the page, external links open in the browser)
Tabs for several documents, recent files, presentation mode (F5)
Reading mode (Ctrl+H): only the pages and a small bar, a comfortable page width, normal, sepia or night page tone, full screen
Opening another PDF while LaserPDF is running opens it in a new tab
### Editing
Edit existing text: click a line and type. The old text is removed from the page and the new text is written in its place without damaging colored or patterned backgrounds. Size, color and bold/italic are kept; the font is replaced with the closest match (letter widths are identical for Arial/Helvetica, Times, Courier and Calibri).
Add text with font, size, bold/italic, alignment, color, background and border
Images: PNG, JPG, WebP, GIF, BMP, or paste from the clipboard (Ctrl+V)
Signatures: draw, type your name or use an image; signatures are saved for next time
Stamps: APPROVED, DRAFT, CONFIDENTIAL, date or date and time, your own text, or a stamp with your name and the date and time
Markup: highlight, underline and strike out text; pen and highlighter
Shapes: rectangle, ellipse, line, arrow (color, fill, width, opacity)
Redact: draw a black or white box; the text and links under it are deleted from the file when you save. If something under it cannot be removed (an image, a scanned page, a form field), LaserPDF offers to turn that page into an image
Links: draw an area that opens a web address or goes to a page of the document
Sticky notes saved as real PDF note annotations
Form filling: text fields, checkboxes and drop-down lists
Every object can be moved, resized, rotated, duplicated, copied and pasted
Annotations panel listing every comment page by page
Undo / redo (150 steps); undoing every change leaves nothing to save
Recovery: unsaved work is kept every 30 seconds and offered back if LaserPDF closes unexpectedly
