How to use the PDF Toolkit
How to Merge PDF Files
Click Merge in the mode tabs, then drop two or more PDF files onto the upload zone. Reorder files by dragging them in the file list, then click Merge PDFs to combine them into a single document.
How to Split a PDF
Click Split in the mode tabs, upload a PDF, then choose a split mode: individual pages, every N pages, or a custom page range. Click Split PDF to generate the output files.
How to Rotate PDF Pages
Click Rotate in the mode tabs, upload a PDF, then select rotation angles (90°, 180°, or 270°) for individual pages using the page thumbnails. Click Rotate pages to apply.
How to Edit PDF Metadata
Click Metadata in the mode tabs, upload a PDF, then edit title, author, subject, keywords, creator, and producer fields. Click Update metadata to save changes to the document.
All processing happens locally in your browser using pdf-lib. Your PDF files never leave your device and no internet connection is required after the page loads.
Frequently Asked Questions
- No. All PDF processing happens entirely in your browser using pdf-lib. Your files never leave your device.
- Yes, 50MB per file. This limit exists because all processing happens in browser memory. For larger files, consider desktop tools.
- Click Extract in the mode tabs, upload a PDF, select the pages you want using the page thumbnails, then click Extract Pages to create a new PDF with only those pages.
- No. Password-protected PDFs cannot be processed. Remove the password first using another tool.
- Merge, split, extract pages, rotate pages, delete pages, and view/edit metadata. All operations preserve content quality.
- Yes. Drag and drop files in the file list to change their merge order. Pages within each file stay in original order.
- Once loaded, the tool works offline because all logic runs client-side. No internet connection required for PDF operations.
Use Cases
PDF Toolkit gives developers a fast, client-side way to work with PDF documents without uploading files to a remote server. Common use cases include merging multiple reports into a single deliverable, splitting large documents into page-range extracts, rotating or reordering pages for better readability, and compressing file size for quicker email attachment or web hosting. Teams also use it to add watermarks or page numbers before distribution, extract text for indexing or data processing, and convert PDF pages to images for preview generation. Because processing happens locally, sensitive contracts, invoices, and internal documentation never leave the user's device, which supports privacy-first workflows and reduces compliance overhead for regulated industries.
How-To
- Open PDF Toolkit in your browser and select the action you need, such as merge, split, compress, rotate, or extract.
- Drag and drop your PDF file onto the upload area, or click to browse and select it from your device.
- Configure the options for your chosen action, for example page ranges for splitting or compression level for file-size reduction.
- Run the process and wait for the toolkit to generate the output file client-side.
- Download the resulting PDF to your computer, or repeat with different settings if the first pass needs adjustment.
PDF Toolkit runs entirely in the browser, so there is no server round-trip and no file retention on external infrastructure. The interface is built for speed and simplicity, with keyboard-friendly controls and clear progress indicators for long-running tasks. Developers can integrate the toolkit into internal documentation pipelines, quality-assurance workflows, or client-facing portals where document handling is required. Supported operations cover the full lifecycle of a PDF, from creation and assembly to optimization and text retrieval, making it a practical utility for any team that works with digital documents regularly.
