PDF Tools
PDF utilities that run in your browser using the pdf-lib library: merge multiple PDF documents into one file, compress PDFs to reduce file size for email and web, and split large PDFs into smaller files by page range.
Merge multiple PDFs into a single document, compress file sizes for email attachments, or split a large PDF into individual pages. All processing happens in your browser — no desktop software or cloud uploads required. Whether you're assembling a proposal from separate chapters, reducing a 20 MB scan for email, or extracting specific pages from a contract, these browser-based PDF utilities handle common document tasks quickly.
Showing 5 PDF tools
PDF editing usually means uploading your documents to someone else's server. These tools run pdf-lib entirely in your browser, so contracts, statements, and scans get merged, compressed, and split without ever leaving your device.
Try PDF Merger first
Combine several PDFs into one — the drag-to-reorder page list makes it painless.
- 1
Upload the files
Add two or more PDFs; they queue in order ready for review.
- 2
Drag to reorder
Rearrange pages or drop the ones you do not need before merging.
- 3
Download the merge
One combined PDF, assembled locally and saved directly to your device.
What Each Tool Does
PDF Merger
Upload multiple PDFs and combine them into one file. Drag to reorder pages before merging. Select specific pages from each input file if you don't need everything.
PDF Compressor
Reduce PDF file sizes by downscaling images and removing redundant objects. Choose a compression level (low, medium, high) and preview the size reduction.
PDF Splitter
Extract specific pages or page ranges from a PDF. Split a 100-page document into individual pages or extract just pages 15-30 for a focused report.
Real Ways People Use These
Merging Proposal Chapters
Your team wrote separate chapters of a business proposal as individual PDFs. Merge them into a single document with the chapters in order.
Compressing for Email
You have a 25MB scanned document that's too large for email. Compress it to under 5MB using high compression, which downscales the scanned images.
Extracting Pages from Contracts
You need to share pages 5-12 of a 40-page contract with your lawyer. Use the splitter to extract just those pages as a separate PDF.
Reorganizing a Report
You have a report where pages got out of order after scanning. Split the PDF into individual pages, reorder them, and merge them back in the correct sequence.
Pick the right tool for the job
Four common scenarios and the tool that handles each one.
| When you need to… | Use | Why |
|---|---|---|
| Combine proposal chapters into one document | PDF Merger | Reorder and select specific pages from each input before merging. |
| Fit a 25MB scan into an email | PDF Compressor | Image downscaling with three compression levels to choose from. |
| Share pages 5-12 of a contract | PDF Splitter | Extract exact page ranges as a standalone file in one click. |
| Fix a scanned report's page order | PDF Splitter + Merger | Split into pages, reorder them, and merge back in the correct sequence. |
Getting the most out of these tools
Preview before downloading
The merge order is exactly what you download — confirm the page list before saving.
High compression is for scans
Downscaling scanned images gives the biggest wins; text-heavy PDFs barely shrink.
Check for encryption first
Password-protected PDFs will not process — remove the password in a PDF viewer first.
How it works
These tools use pdf-lib, an open-source JavaScript library for creating and modifying PDF documents. It operates on the PDF structure directly in the browser, which means it can handle most standard PDFs but may not support all features of complex PDFs (like encrypted or DRM-protected files).
