Are my PDF files uploaded to a server?

No. All PDF processing happens entirely in your browser using the pdf-lib library. Your files never leave your device and are not sent to any server, making this tool 100% private and GDPR-friendly.

How do I merge multiple PDFs into one?

Select the Merge PDF tool, upload two or more PDF files using the file picker or drag and drop, then click "Merge & Download". The PDFs are combined in the order they appear in the list.

How do I split a PDF by page range?

Select the Split PDF tool, upload your PDF, then enter your page ranges in the format 1-3,5,7-9. Each range creates a separate downloadable PDF file.

Can I rotate only specific pages in a PDF?

Yes. In the Rotate PDF tool, enter specific page numbers (e.g. 1,3,5) to rotate only those pages, or leave the field blank to rotate all pages.

How much does this compress a PDF?

Compression works by re-saving the PDF with stream compression enabled. PDFs with large amounts of uncompressed metadata, text, or vector graphics will see the most reduction. Image-heavy PDFs may see little change since the image data is already compressed.

Tool Guide

🔗 Merge PDF

Combine two or more PDF files into a single document. Upload files in the order you want them merged and click Merge & Download. The result is a single PDF containing all pages from all files.

✂️ Split PDF

Extract specific pages from a PDF using page ranges. Enter ranges like 1-3,5,7-9 to create separate PDF files for each range. Useful for extracting chapters, invoices, or individual sections.

🔄 Rotate PDF

Fix landscape pages, scanned documents, or sideways content. Choose a rotation angle (+90°, +180°, +270°, or −90°) and optionally specify which page numbers to rotate. Leave the pages field blank to rotate all pages.

📦 Compress PDF

Reduce PDF file size by re-encoding the document with object stream compression. Most effective on text-heavy and vector-graphic PDFs. After compression, you see the before and after file sizes.
