How do I split a PDF file?

Upload your PDF, then select the pages you want to extract. You can choose individual pages, page ranges, or split the document at specific points. Click "Split PDF" and download your results.

Can I extract just one page from a PDF?

Yes. After uploading, simply select the single page you need and extract it as a standalone PDF file.

Is there a file size limit?

Since processing happens in your browser, the limit depends on your device's available memory. Most devices handle PDFs up to 100MB without issues.

Will splitting affect the quality of my PDF?

No. The tool extracts pages without re-encoding, so all text, images, and formatting remain exactly as they were in the original document.

Are my files secure when splitting PDFs online?

Completely. Your PDF never leaves your device. All processing happens locally in your browser using JavaScript. No data is transmitted to any server.

How do I split a PDF into specific pages?

Upload your PDF file, then enter the page numbers or ranges you want to extract in the input field. Use commas to separate individual pages and hyphens for ranges. For example, '1-3, 5, 7-10' will extract pages 1 through 3, page 5, and pages 7 through 10 into a new PDF document.

Can I extract a single page from a PDF?

Yes. Simply enter the page number you want to extract, such as '5' to get only page 5. You can also extract multiple individual pages by separating them with commas, like '2, 5, 8' to get pages 2, 5, and 8 in a new document.

Does splitting a PDF affect the original file?

No. The original file is never modified. The tool creates a brand-new PDF containing only the pages you selected. Your original document remains exactly as it was on your device.

Is there a page limit for splitting PDFs?

There is no artificial page limit. You can split PDFs with hundreds of pages. The only constraint is your device's available memory. For very large documents with thousands of pages, processing may take a few extra seconds.

Are my files uploaded to a server when splitting?

No. All processing happens entirely in your browser. Your PDF file is read into your device's memory, the selected pages are extracted using client-side JavaScript, and the result is saved directly to your device. No data is ever sent to any server.
