Frequently Asked Questions

How do I extract pages from a PDF?

∨
Open the PDF, switch to Select pages mode, and check the thumbnails of the pages you want. The quick tools let you select all pages, odd pages, even pages, or type a range like 5-20 to check it instantly. Press Extract selected to download the chosen pages as a single PDF.

How do I delete unwanted pages from a PDF?

∨
Check the pages you want to remove, then press Invert: the selection flips to all remaining pages. Press Extract selected and you get a PDF with the unwanted pages removed. This is the fastest way to strip covers, blank pages, or scans from a document.

How do I split a PDF into equal parts?

∨
Switch to Split every N pages and enter the number of pages per part, for example 5 or 10. All pages are selected and grouped automatically, with group bands shown in the grid. You can uncheck pages to exclude them, then split and save the parts as a ZIP archive.

How do I split a PDF into single pages?

∨
Switch to Split into single pages. Every page becomes its own PDF file, named page-1.pdf, page-2.pdf, and so on. Uncheck any page you do not want, then save the output as a ZIP archive for easy download.

Can I preview pages before splitting?

∨
Yes. The thumbnail grid shows every page of the document, and clicking any thumbnail opens a large preview on the right with previous/next buttons and a page-number jump box. You can verify exactly which page is the signature, the chapter start, or the blank scan before deciding where to split.

Can I select odd or even pages?

∨
Yes. In Select pages mode, the Odd pages button checks pages 1, 3, 5, and so on, and Even pages checks 2, 4, 6. This is handy for double-sided scans where you only need the front or back side.

Will my pages change during splitting?

∨
No. Pages are copied exactly as they are: text, images, fonts, links, bookmarks, and layout are preserved without any modification. Each part is a clean copy of the original pages.

Can I split a large PDF with hundreds of pages?

∨
Yes. Thumbnails are rendered lazily only for pages near the viewport, and the parsed document is reused across renders, so even a 500-page scanned PDF stays responsive while you scroll and select.

Is my PDF uploaded anywhere?

∨
No. All processing happens locally in your browser with JavaScript. Your file is never uploaded, stored, or transmitted anywhere, which makes the tool safe for contracts, medical documents, and other confidential PDFs. It even works offline.

What are the output file names?

∨
Names describe the content: parts from the every-N mode are named part-1.pdf, part-2.pdf, single pages are page-3.pdf, and an extracted selection is pages-3-6.pdf for a continuous range or pages-3-6-9.pdf for separate pages. The ZIP archive is named after your original file.

Why do I get an error when opening my PDF?

∨
The file may be damaged or password-protected. pdf-lib cannot open encrypted PDFs, so a password-protected document shows an error message. Try opening the file in a PDF viewer first to confirm it is valid and not locked.

Can I split PDFs on my phone?

∨
Yes. The tool is fully responsive: the page grid, preview, and selection tools work on touch screens, and the output is saved as a ZIP archive so mobile downloads stay simple.

What happens if my PDF has only a few pages?

∨
Everything works the same: select pages, preview them, and split. If a part would be empty (for example every-5 mode on a 3-page document), the tool simply produces one part with the pages that exist.

How can I combine the parts back into one file?

∨
Use the PDF merge tool on this site: open all the parts in order and merge them into a single document. Because splitting never alters the pages, the merged file is identical to the original.
