Are my PDF files uploaded when I split?
No. Splitting runs entirely in your browser with pdf-lib and pdf.js for thumbnails. Your PDF is read from device memory and the output is generated locally—it is not sent to EverydayTools servers for normal use.
How can I verify my PDF is not uploaded?
Open your browser Developer Tools → Network tab, filter by Fetch/XHR, then upload and split a PDF. You should see no requests carrying your PDF file to external servers. Only static assets (JavaScript, the pdf.js worker) load from the site.
What is the difference between Split PDF, Extract PDF Pages, and Remove Pages?
Split PDF (this tool) copies selected pages into new output: pick/ranges → one combined PDF; split every page → ZIP of single-page files. Extract PDF Pages is a sibling tool focused on pulling page subsets from one PDF—overlapping with pick/ranges here. Remove Pages deletes specified pages and keeps the rest—better when you want to drop a few pages from an otherwise complete document.
Does Split PDF work on phones and tablets?
Yes. The layout is responsive with touch-friendly controls, a sticky Split action bar on mobile after you scroll, and a virtualized thumbnail grid for large PDFs. Very large files (hundreds of pages) may process slowly on low-memory phones.
When do I get a ZIP file versus a single PDF?
Pick pages and Text ranges always download one combined PDF with your selection. Split every page downloads a ZIP containing page-1.pdf, page-2.pdf, and so on—one PDF per page.
Can I split a password-protected PDF?
Not without unlocking it first. pdf-lib cannot read encrypted PDFs without the password. Remove protection in your PDF reader (with authorization), save an unlocked copy, then split.
PDF page 1 vs printed page numbers— which does the tool use?
The tool uses PDF page order: page 1 is always the first page in the file, even if the sheet prints "Page 50" in the footer. Use thumbnail previews in Pick mode to match visual content to numbers.
Can I split into individual pages (one PDF per page)?
Yes. Choose Split every page. The result is a ZIP download with one PDF per page, named page-1.pdf, page-2.pdf, etc.
How do I enter text ranges like 1-3, 5, 7-9?
Select Text ranges mode (or edit the synced field in Pick mode). Use hyphens for ranges and commas between parts: `1-3, 5, 7-9` selects pages 1,2,3,5,7,8,9 in that order in one output PDF.
Will the split PDF preserve bookmarks and links?
Hyperlinks within the extracted page range are preserved. Document-level bookmarks referencing pages outside your selection may not work in the output, since those pages are not included.
Does splitting affect text or image quality?
No. Splitting copies page objects without re-encoding or re-rendering. Text, fonts, images, and vector graphics in selected pages match the originals.
What is the maximum file size and page count?
Up to 100 MB per PDF. There is no hard page limit, but very large documents take longer because processing runs in your browser. The virtualized grid helps preview large files without rendering every thumbnail at once.
Will splitting reduce the file size?
Yes—roughly proportional to pages kept. A 50 MB 20-page PDF split to 5 pages often yields about 10–15 MB. For further reduction, run the output through Compress PDF.
What happens to form fields in extracted pages?
Form fields on selected pages are copied to the output. Filled values remain. Cross-page validation rules referencing pages you did not include will no longer function.
Is Split PDF free and does it add watermarks?
Yes—free with no signup and no watermark on downloaded PDFs or ZIP files.
