Each page will download as a PNG image.
How it works
How it works: we use the pdf-lib library right in your browser to rewrite PDF files page by page (merge, split, rotate, unlock, watermark, numbering), and pdf.js to convert pages to images. Everything happens locally.
Use cases
- Merge the 12 PDFs of your thesis into one document before sending it to your advisor
- Split a 200-page manual and keep only the single chapter you actually need to study
- Compress your 25MB PDF portfolio to under 5MB so you can upload it to LinkedIn
Frequently asked questions
Are my documents uploaded to any server?
No. All processing happens in your browser with pdf-lib. Your PDFs never leave your device.
How do I merge PDFs?
Pick two or more files in the order you want and hit "Merge into one PDF". Pages are copied in that order into a single downloadable document.
How do I extract specific pages?
Upload the PDF and enter the range as 1-3, 5 (pages 1 to 3 plus page 5). You get a new PDF with just those pages.
How much smaller can a PDF get?
It depends: PDFs with images often shrink 10–40%. Already-optimized files barely change. Optimization does not reduce visible quality.
How do I rotate only some pages?
Enter the range as 1-3, 5. Leave it empty to rotate every page in the document.
What does "Unlock PDF" do?
If your PDF has an open password and you know it, the tool creates a copy without the password. It cannot crack unknown passwords.
Can the watermark be removed later?
The watermark is baked into each page content, not an annotation: it cannot be removed with a click, just like professional tools.
