How to Extract Pages from a PDF
Need to save just one page from a large report? Or maybe break a book into chapters? Andromeda PDF's Split tool lets you extract exactly what you need without waiting for uploads.
Upload Your Document
Drag and drop your PDF file into the box above. The tool will instantly analyze the file and tell you how many pages it has.
Define Your Range
Enter the page numbers you want to keep. You can use single numbers (e.g., "5") or ranges (e.g., "1-10"). Combine them with commas, like "1-5, 8, 11-13".
Extract and Save
Click "Extract Pages". Your new PDF containing only the selected pages will be created instantly in your browser ready for download.
Why Split PDFs Locally?
When you use server-side tools to split a PDF, you have to upload the entire document even if you only want one page. If you have a 100MB 500-page manual, that's a lot of wasted bandwidth.
The Efficiency Boost: With Andromeda PDF, the file stays on your disk. The browser simply reads the parts you want and creates a new file. It's often 100x faster than uploading.
Technical Insight: Zero-Latency Extraction
Our split algorithm uses Random Access Memory (RAM) mapping. Instead of reading the whole file linearly, we jump directly to the Byte Offsets specified in the PDF's trailer dictionary.
This means retrieving Page 500 of a 1,000-page document takes the exact same amount of time as retrieving Page 1 (O(1) complexity). Server-side tools often have to parse the entire stream (O(n)), making them significantly slower for large documents.
