100% Client-Side PDF Toolkit
PDF tools you can add now — no backend required
Every tool below can run entirely in the browser using libraries like pdf-lib, pdf.js, and WebAssembly. That means no uploads, no server costs, and full privacy for your users.
Organize & Prepare
Core editing actions that are fast and safe with client-side PDF engines.
- Merge multiple PDFs into one
- Split PDFs by page ranges or extract specific pages
- Reorder, rotate, delete, or duplicate pages
- Create PDFs from images (JPG/PNG/WebP)
- Add page numbers, headers, and footers
Convert & Export
High-quality exports and format conversions that stay on-device.
- PDF → JPG/PNG (with DPI presets and batch processing)
- PDF → Text (searchable text extraction)
- PDF → Images (all pages or custom ranges)
- Markdown → PDF (browser print engine)
- Images → PDF (single or multi-page output)
Edit & Annotate
Visual tools built on canvas overlays and PDF drawing APIs.
- Add signatures (draw, type, or upload)
- Add text boxes, highlights, shapes, and stamps
- Insert images, logos, or watermarks
- Redact content by burning in blocks
- Fill and flatten PDF form fields
Security & Optimization
Privacy-first tools that avoid any server round trips.
- Compress PDFs with WebAssembly (quality presets)
- Add or remove passwords locally
- Metadata editor (title, author, keywords)
- Unlock PDFs by re-rendering pages
- Detect large-file risks and show memory warnings
Smart & Advanced
Power features that still run entirely in the browser.
- OCR on scanned PDFs with on-device OCR engines
- Compare PDFs with visual diff previews
- Split/merge in batches for large documents
- Local search + highlights across long PDFs
- Optional AI chat with PDF using extracted text (no file uploads)
Why these are safe client-side
- All processing happens in the browser via WebAssembly and PDF libraries.
- Files never leave the device, so privacy is preserved by default.
- Offline support is possible after first load via caching.
- Memory-aware batching prevents crashes on large files.
