About PDF Splitter

PDF splitting is the process of dividing a PDF document into multiple smaller files by removing specific pages. This essential tool allows you to extract relevant sections, remove unwanted pages, or create separate documents from a single source file. Our PDF Splitter provides an intuitive, fast, and secure way to split your documents online.

Unlike traditional PDF splitters that require you to manually select which pages go into each file, our smart tool automatically creates separate PDFs based on the pages you want to remove. Simply specify the page numbers to delete, and the tool will intelligently split your document into continuous ranges, making it perfect for quick document organization.

How to Split PDFs

  1. Upload Your PDF: Click the upload area or drag and drop your PDF file.
  2. Specify Split Points: Enter the page numbers where you want to split (e.g., "3,7" to split a 10-page PDF into [1-3], [4-7], [8-10]).
  3. Split PDF: Click the "Split PDF" button to start the process.
  4. Review Results: See how many separate PDF files were created.
  5. Download: Download all files as a ZIP archive, download them one by one automatically, or select individual files to download.

Frequently Asked Questions

How does the page numbering work?

Page numbers start from 1. You can specify individual pages (e.g., "1,3,7") or ranges (e.g., "3-5" for pages 3, 4, and 5). Combine both methods: "1,3-5,7,10-12" will remove pages 1, 3, 4, 5, 7, 10, 11, and 12.

How many output files will be created?

The tool automatically creates PDFs based on continuous page ranges. For example, if you have a 10-page PDF and remove pages 3 and 7, you'll get 3 files: pages 1-2, pages 4-6, and pages 8-10.

Will the quality of my PDF be maintained?

Yes! Our split process maintains 100% quality. All text, images, formatting, hyperlinks, and metadata from your original PDF are preserved exactly as they were in the resulting split files.

Is my data secure? What happens to my files?

Absolutely secure. All files are processed on our secure servers and are automatically deleted within 5 minutes after splitting is complete. We do not store, share, or access your documents.

Can I split password-protected PDFs?

Currently, our tool does not support password-protected PDFs. You'll need to remove the password protection from your PDF before uploading it for splitting.

What's the maximum PDF size I can split?

You can split PDFs up to 100MB in size through our web interface. For larger files or bulk operations, consider using our API service.

How long does the splitting process take?

Splitting is typically very fast, usually taking just a few seconds depending on the size of your PDF and the number of pages being processed.

Privacy & Security

Secure Processing: All PDF splits are processed on our secure servers using industry-standard encryption. Your files are transmitted over HTTPS to ensure data privacy during upload and download.

Automatic Deletion: We take your privacy seriously. All uploaded PDFs and the generated split files are automatically deleted from our servers within 5 minutes after the split completes. We retain no copies of your documents.

No Data Collection: We do not collect, store, or analyze the content of your PDFs. Our system only processes the files to perform the requested split and then removes all traces.

GDPR Compliant: Our service is fully compliant with GDPR and other international data protection regulations. You maintain full ownership of your documents throughout the split process.
