PDF Studio

How to use the PDF Studio

Choose a tool from the tabs above: Compress to shrink file size, Merge to combine several PDFs into one, Split to pull out selected pages, or Extract Images to grab every embedded picture as a PNG. Everything runs locally in your browser.

Why work on PDFs in the browser?

Merging, splitting, compressing and pulling images out of a PDF usually means uploading confidential contracts and statements to a converter. Here the file stays on your machine, so you can handle payslips, IDs and contracts without leaving a copy on someone else’s server.

Step by step: pick and run an operation

1. Choose the operation you need: merge, split, compress or extract images.
2. Drop the PDF, or several PDFs for a merge.
3. Set the options — page ranges for a split, or the quality level for compression.
4. Run the operation and download the result.

Quick reference

Operation	When to use it
Merge	Combine several documents into a single file
Split	Separate chapters, or email one section at a time
Compress	Shrink a file below an upload limit
Extract images	Reuse figures from a report or slide deck

Getting the result you expect

• Merge order follows the order you add files, so arrange them before you combine.
• Compression trades image quality for size; check the result before deleting the original.
• Use page ranges on a split so you get exactly the sections you need.
• Keep a copy of the original PDF, since some operations re-encode images.

Is it private and secure?

Yes. Your PDF files are processed entirely on your device using pdf-lib and pdf.js. Nothing you upload is ever sent to, tracked or stored on any server.
