Split a PDF and extract the pages you need

Sometimes you need page 7 of a 200-page report, not the whole report. Give the tool a range, get exactly those pages as a new file. Useful when you have to send one section of a contract to someone who has no business reading the rest of it.

• Range syntax like 1-3, 7, 12-20 in one go
• Produce several output files from one source
• Original document is left untouched
• Nothing is uploaded, so the pages you did not extract stay private

Frequently asked questions

What range syntax is supported?

Comma-separated single pages and ranges, for example 1-3, 7, 12-20. Pages are numbered from one, the way they are printed, not from zero.

Can I split one PDF into many separate files?

Yes. Define several ranges and each one comes back as its own file.

Is splitting lossless?

Yes. Pages are copied verbatim into the new document with no re-encoding, so nothing degrades.

Guides and benchmarks

• OCR that looked like it worked - Five bugs in a browser OCR pipeline, every one of which produced a plausible success instead of an error. Measured before and after, with the code paths named.
• How small a PDF actually gets, from 50 KB to 1 MB - Five test files, both presets, and which size targets each one clears. Measured in the browser, with nothing uploaded at any point.
• What PDF compression actually does, measured - Every PDF site claims "up to 90% smaller" and none of them show their corpus. Here are the numbers for this one, the documents they came from, and how to reproduce them.
