A fully client-side PDF toolkit for compressing, editing, signing, and converting. No server, no uploads, no dependencies — everything runs in the browser.
- Re-renders every page as JPEG at adjustable quality (10–100%)
- Rebuilds the PDF using object streams for smaller file size
- Option to strip all metadata (title, author, subject, keywords, producer, creator)
- Batch compression across multiple files with per-file progress
- Visual page view — open any PDF to see full-page canvas renders
- Page selection — Click to select, Ctrl/Cmd+Click to toggle, Shift+Click for ranges
- Delete pages — remove selected pages from a PDF
- Reorder pages — drag and drop pages to rearrange order
- Select All for quick bulk operations
- Load a signature image (PNG, JPEG, or WebP)
- Visual page picker with thumbnails to choose which page to sign
- Interactive positioning — drag the signature overlay directly on the page
- Resize handle — drag the corner handle to scale the signature
- Fine-tune sliders — X position, Y position, and size (all synced with drag)
- Applies the signature permanently into the PDF
- Drop images (JPEG, PNG, WebP, GIF, BMP, TIFF/TIF) to create a new PDF
- TIFF support via built-in decoder
- Configurable page size: A4, Letter, Legal, or Fit to image
- Adjustable margin (0–200 px)
- One image per page option
- Drag & drop or click to browse — supports multiple PDFs and images at once
- Multi-select: Click to select, Ctrl/Cmd+Click to toggle individual files, Shift+Click to select ranges
- Remove selected or Clear all
- File list showing name, size, page count, and status
- Bottom bar with file count, total pages, and total size
- Customizable output filename or same-as-input naming
- Download individual PDFs from page view
- Batch compress & download all loaded files
- Dark theme with orange accent (
#FF4D00) - Real-time status pill: green (ready), purple (loading), red (error)
- Bottom bar with file count, total pages, and combined size
- Toast notifications for quick feedback
Everything runs in the browser. The HTML file loads a few local library files — no build step, no package manager, no external requests.
Bundled libraries (inline):
| Library | Purpose |
|---|---|
| pdf-lib | PDF creation, editing, page manipulation, and image embedding |
| pdf.js | PDF rendering to canvas (page previews and compression pipeline) |
| UTIF.js | TIFF/TIF image decoding |
Custom implementations (no external library):
- Drag-and-drop page reordering with visual feedback
- Interactive signature overlay with drag, resize, and slider sync
- JPEG-based compression pipeline (pdf.js render → canvas → JPEG → pdf-lib rebuild)
- TIFF to PNG conversion pipeline for image-to-PDF workflow
There's nothing to install. No npm install, no build tools, no frameworks, no Docker, no server. It's a single HTML file with all dependencies bundled inline. Just open pdf-tool.html in your browser.
No internet connection needed — everything is self-contained.
- Open
pdf-tool.htmlin any modern browser - Drop PDFs or images onto the drop zone (or click to browse)
- Double-click a PDF to open the page view for editing, reordering, or signing
- Adjust compression, signature, or export settings in the right panel
- Click Compress & Download All or Download PDF
Works in all modern browsers (Chrome, Firefox, Edge, Safari).
This project uses the following open-source libraries:
- pdf-lib — Create and modify PDF documents in any JavaScript environment (MIT)
- PDF.js — Mozilla's PDF rendering library (Apache 2.0)
- UTIF.js — TIFF decoder in JavaScript (MIT)
