PDF Utility Tools
Merge, split, rotate, extract pages, and convert images to PDF, all directly in your browser. Your files never leave your device.
About these PDF tools
These PDF utilities are built on pdf-lib, a pure JavaScript library for creating and editing PDFs. Because the library runs entirely in your browser, your files never touch a server, which is important for sensitive documents like contracts, tax records, or medical information.
Supported operations
- Merge: combine multiple PDFs into a single document. Use the arrows to set the order before merging.
- Split: split a PDF by page ranges (e.g. "1-3, 5, 7-10"). Each range becomes its own PDF.
- Extract: click the pages you want and get them as a new single PDF.
- Rotate: rotate selected pages 90°, 180°, or 270°.
- Reorder / Delete: reorder pages or delete pages from a PDF.
- Image to PDF: combine PNG and JPG images into a PDF, one image per page.
When to use a client-side PDF tool
Most online PDF tools upload your documents to a server, process them there, and let you download the result. That's fine for non-sensitive files, but for confidential documents, you really don't want to ship them off to a third party. This tool never does that.
Questions
Are my files uploaded to a server?
No. Every operation runs locally in your browser using the pdf-lib JavaScript library. Your PDFs never leave your device, and once the page has finished loading the tools keep working offline.
Is there a file size limit?
There is no fixed limit, but processing speed depends on your device. Most modern browsers comfortably handle PDFs up to several hundred megabytes; very large files take longer.
Can I convert images to PDF?
Yes. The Image to PDF tab takes PNG and JPG images (and other formats your browser can open) and puts them into a single PDF, one image per page, on A4, Letter or image-sized pages. Image to PDF opens straight on that tab.
What page ranges can I use when splitting?
Comma-separated ranges such as 1-3, 5, 7-10. Each range becomes a separate PDF delivered in a ZIP, or choose Combine into one PDF to put all those pages, in the order typed, into a single file.
Limitations
Because everything runs in-browser, very large PDFs (hundreds of megabytes) may be slow or run out of memory on low-end devices. Password-protected PDFs must be unlocked before editing. OCR (converting scanned PDFs to text) is not included in this tool.
