PDF Split

Split a PDF into multiple independent files in your browser. Files stay on your device — nothing is uploaded. Three modes cover most needs: a range syntax (for example, 1-3,5,7-9) for picking exactly which pages go where, an "every N pages" mode for even splits, and a single-page mode that produces one PDF per page. Output filenames include zero-padded numbers (split-001-003.pdf), so the parts sort in page order in any file manager. Typical uses include extracting signature pages from a contract, splitting long reports into chapters, archiving a scanned book one page at a time for OCR, pulling a single invoice out of a monthly bundle, and breaking an application package into separate submissions.

  • Three split modes for common needs: page ranges, every N pages, and single pages.
  • Page ranges are validated as you type. Out-of-bounds, negative, or descending ranges show a clear error.
  • Output filenames use zero-padded numbers (split-001-003.pdf) so the parts sort in page order in any file manager.
  • The total page count is read on upload and used as the input ceiling.
  • Multiple outputs can be downloaded as a single ZIP, or saved one at a time from the result list.
  • Page content (fonts, images, and text) is preserved, so each output stays searchable and copyable.
  • All processing runs in the browser. Files are not uploaded to a server.

Commands

Overview

Cuts a PDF into multiple independent files at the granularity you choose, from page ranges down to one PDF per page.

  1. 01

    Split by ranges

    Use the 1-3,5,7-9 syntax to control exactly which pages go into each output. Useful for splitting by chapter, by attachment, or by signature page.

  2. 02

    Split every N pages

    Set a fixed page count (for example, every 10 pages). The tool walks the document from start to finish and folds any remainder into the final part.

  3. 03

    Split into single pages

    Turn every page into its own PDF with one click. Suitable for scan organization, per-page archival, and per-page submissions.

  4. 04

    Page content preserved

    Fonts, embedded images, vector graphics, and text content are copied into each output. The text remains searchable and copyable.

  5. 05

    Local processing

    All splitting happens in the browser. File bytes never leave your device, which suits contracts, ID scans, and medical records.

  6. 06

    ZIP download

    Multiple outputs can be downloaded as a single ZIP. Files are named with the page range (split-001-003.pdf, split-004-006.pdf).

  7. 07

    Per-part download

    Or download a single output from the result list without grabbing the whole ZIP.

  8. 08

    Encrypted PDF detection

    When a password-protected PDF is loaded, the tool shows a clear error message instead of silently failing.

How to use

From upload to download usually takes only a few seconds.

  1. 01

    Click "Select PDF" or drop a PDF onto the upload area. The total page count is read automatically.

  2. 02

    Pick a split mode. "Page ranges" is for precise control, "Every N pages" for even chunks, "Single pages" for one PDF per page.

  3. 03

    Fill in the parameters. Page ranges use the 1-3,5,7-9 syntax. Every N pages takes a positive integer. Single pages takes no input.

  4. 04

    Set an output filename prefix, for example contract, chapter, or scan. The tool appends the page-range suffix automatically.

  5. 05

    Click "Split". Processing runs locally and usually finishes within a few seconds.

  6. 06

    When the split is done, each part shows its page range, page count, and size. Click "Download ZIP" for a bundle, or download individual parts from the list.

  7. 07

    If the result is not what you wanted, change the mode or parameters and split again. The source PDF is never modified.

  • Each output shows its page range, page count, and file size
  • Live totals: source pages, output parts, and combined output size
  • Output filenames use zero-padded numbers so the parts sort in page order
  • The prefix input filters out characters that are illegal on Windows
  • All processing runs in the browser; nothing is uploaded
  • Per-part download or full-ZIP download
  • Clear error message when an encrypted PDF is loaded
  • Compatible with Chrome, Edge, Firefox, Safari, and Brave, plus mobile browsers
  • Free to use, with no watermarks and no ads

Use cases

Everyday situations where one PDF needs to become several.

  1. Extract signature pages

    Pull only the signed or stamped pages from a multi-page contract to return to a client without exposing the rest of the document.

  2. Split long reports by chapter

    Cut a multi-chapter project report, year-end summary, or academic paper into independent chapters for parallel review or printing.

  3. Archive a scanned book page by page

    Turn a scanned book into one file per page for per-page OCR, organization, or import into a note system.

  4. Pull a single e-invoice

    Extract one invoice out of a monthly bundle for reimbursement, categorization, or upload to an accounting system.

  5. Distribute lectures by chapter

    Cut a full-semester lecture PDF into weekly or chapter-sized parts so students do not download a hundreds-of-MB file at once.

  6. Resume attachments per HR system

    Pull recommendation letters, transcripts, or portfolio pages out of a packaged resume for different HR submission requirements.

  7. Legal evidence by page

    Extract specific evidence and attachment pages from a case PDF for attorney annotation, presentation, or filing.

  8. Itemize medical records

    Split a consolidated PDF into lab reports, imaging notes, and prescriptions for follow-ups, insurance claims, or second opinions.

  9. Split ebook chapters

    Break an ebook PDF into chapter-sized parts for chapter-by-chapter reading, printing, or e-reader syncing.

  10. Application packages by section

    Split a bundled application into per-section PDFs (cover, statement, certificates) per tender or admission specifications.

After extracting the pages you need, use PDF Merge to put selected parts back into a clean packet, then protect sensitive signatures, IDs, or records with File Encryption . For more PDF, document, image, and media utilities, browse the File category page.

Best practices

Most failures come from range syntax and the single-page mode. These tips are specific to splitting.

  • Use ASCII characters in ranges: comma, hyphen, and Arabic digits. Pasting from a Chinese or Japanese document often brings full-width punctuation, which is the most common cause of failures.
  • Within a range, write in ascending order (7-9, not 9-7). If you need pages in reverse, that is a merge-time reordering, not a split-time one.
  • Ranges may overlap, for example 1-3,2-4. The tool produces two independent PDFs that share pages 2 and 3.
  • Single-page mode produces one file per source page. For a 500-page PDF, that is 500 files. Use the ZIP download.
  • Add a meaningful prefix like contract-acme, scan-q2, or handout-week3 so the outputs sort sensibly later.
  • When you see an out-of-range error, check the total page count shown at the top of the panel before changing the input.
  • For page-level editing (delete a few pages, reorder, extract and reinsert), use split plus merge as a two-step flow. The source stays untouched.
  • PDFs over 100 MB use a lot of memory. Compress or close other tabs first.
  • For sensitive single-page outputs (signature pages, IDs), add password protection before distribution. Single-page files are easier to forward unintentionally than full documents.
  • After splitting, open each part locally to check orientation, fonts, and blank pages. In single-page mode, sample a few outputs.
  • When handling sensitive content, use a private browsing window or offline environment, and clear your browser download history afterwards.

Limitations

Side effects that are specific to splitting and worth knowing before a critical workflow.

  • Document outlines (bookmarks) and cross-file page jumps do not transfer to the split outputs. Bookmarks that point to other pages may stop working.
  • Cross-page hyperlinks and table-of-contents jumps resolve in the source PDF but may dangle after splitting if the target page lives in a different output.
  • PDF form fields, annotations, and digital signatures may not survive splitting. Revalidate with a professional PDF tool if you rely on them.
  • Single-page mode produces many files. A 500-page PDF becomes 500 files. Use the ZIP download.
  • Descending and reverse-output ranges are rejected. Range 9-7 is invalid. Reordering belongs to merging, not splitting.
  • The tool does not recompress content. Each output is proportional in size to its share of the source.
  • Output metadata is regenerated by the tool and does not come from the source PDF.
  • Encrypted, corrupted, strict PDF/A or PDF/X, and DRM-protected files may fail to load or parse.
  • Embedded JavaScript actions do not follow pages into the split outputs. If the source PDF relies on scripts to control form behavior, the parts may behave differently.

FAQ

Common questions about splitting itself, plus the usual ones about safety, versions, and compatibility.

Can ranges overlap, for example 1-3,2-4?

Yes. The tool produces two independent PDFs in the order written: pages 1-3 first, pages 2-4 second. Pages 2 and 3 appear in both.

Can I write a descending range like 9-7?

No, that is rejected. Descending ranges have no clear meaning in a split context. If you need pages in reverse, split first and then use a PDF merge tool to reassemble in your desired order.

What is the "001" in output filenames?

It is zero padding. With files named split-1.pdf, split-2.pdf, ..., split-10.pdf, a default alphabetical sort would put 10 before 2. The padding width is chosen based on the source page count, with a minimum of three digits.

How many files does single-page mode produce?

One file per source page. A 500-page PDF becomes 500 files. Use the ZIP download.

Why did my bookmarks and TOC links stop working after splitting?

Bookmarks and outlines are document-level metadata. They are not copied into the split outputs. If you rely on bookmarks, merge the relevant parts back, or rebuild the bookmark tree on the result.

How do I extract scattered pages like 3, 12, and 20?

Use single numbers separated by commas: 3,12,20. The tool produces three independent PDFs, one per page. To combine them into a single file, run those three through a PDF merge tool.

Does splitting change page size, orientation, or resolution?

No. Each page is copied as a whole page object, so dimensions, orientation, embedded image resolution, and the text layer remain identical to the source.

Can I split scanned (image-only) PDFs? Will OCR still work afterwards?

Yes. Splitting only handles page objects and does not care whether the content is text or raster. Run OCR on each output afterwards. Per-page OCR is often more reliable than running OCR on the full book at once.

Are watermarks, annotations, and signatures preserved?

Watermarks that live inside the page content are copied with the pages. Annotations and signatures depend on their type. Some may be lost or invalidated after splitting; check the outputs in a professional PDF tool if you rely on them.

Can encrypted (password-protected) PDFs be split?

No. Password-protected PDFs are caught at load time. Decrypt the file first with a dedicated PDF unlock tool, then split.

Can the split parts be merged back together?

Yes, and that is a common pattern: split → edit or replace externally → merge. The source PDF is never overwritten, so you can always go back to the original.

How many parts can be produced from one PDF?

There is no hard limit. Browser memory is the practical constraint. Hundreds of parts from a several-hundred-page PDF works fine on desktop Chrome. For very large or high-resolution scans, compress the source first or split in two passes.

Does this work on phones?

Yes. iOS Safari, Chrome, Edge, Firefox, and Android Chrome all support it. Mobile memory is limited; prefer a desktop browser for scanned PDFs over 50 MB.

How does this differ from iLovePDF Split, SmallPDF, or Adobe Acrobat?

The main difference is processing: this tool runs locally in your browser; online services usually upload to a server and return the result. Feature-wise, this tool focuses on splitting and does not include OCR or PDF-to-Word conversion.

Are split outputs ready to send directly to clients?

Yes — no watermarks, no ads, no tool branding. If the output contains sensitive information (signature pages, IDs), add password protection before sending.
