PDF Splitter Online – Extract Pages From a PDF, Free
By the CSC Tool Hub editorial team · Last reviewed September 2026
CSC Tool Hub's PDF Splitter divides a PDF into separate files — either one file per page, or custom ranges you define — entirely in your browser. Two things about this tool routinely confuse people: exactly what the range syntax produces, and why the browser sometimes blocks the downloads. Both are explained below, since knowing them upfront saves a lot of retries.
How the Custom Range Syntax Actually Works
This is the part most people get wrong: each comma-separated part becomes its own separate output file — it does not combine them into one PDF.
| What you type | What you get |
|---|
1-3 | One file containing pages 1, 2, 3 |
1-3, 5 | Two files: one with pages 1-3, one with page 5 alone |
1-3, 5, 7-9 | Three files: pages 1-3, page 5, pages 7-9 |
2 | One file containing only page 2 |
So if you want pages 1, 2, 3, 5, 7, 8 and 9 all in one PDF, split them out first and then combine the results using a PDF merge tool — this splitter intentionally keeps each range as its own file.
Why Your Browser May Block the Downloads (and How to Fix It)
Choosing "Each Page Separately" on a 20-page PDF triggers 20 separate downloads in quick succession. Chrome, Edge and most other browsers block automatic multiple downloads by default and show a small prompt near the address bar asking whether to allow them.
- If only the first file downloaded: look for a blocked-downloads icon in the address bar and choose "Allow", then run the split again.
- To avoid the prompt entirely: use Custom Range with fewer parts, which produces fewer files.
- On mobile: many mobile browsers handle multiple simultaneous downloads poorly — splitting large documents is more reliable on a desktop browser.
Which Split Method Should You Use?
| Situation | Best method |
|---|
| Scanned batch where each page is a separate document | Each Page Separately |
| Extracting one certificate from a bundled PDF | Custom Range (single page, e.g. 4) |
| Splitting a report into chapters | Custom Range with one part per chapter |
| Submitting only specific pages of a long form | Custom Range |
What This Tool Can't Do
- Password-protected PDFs: encrypted files can't be read without the password. Remove protection first, then upload.
- Preserving bookmarks and form fields: page content, fonts and layout copy over exactly, but bookmarks and fillable form fields from the original aren't carried into split files.
- Reordering pages during the split: pages come out in their original document order — reorder afterward with a merge tool if needed.
- Combining non-adjacent pages into one file: see the range syntax section above for the workaround.
How to Use This PDF Splitter
- Upload Your PDF: drag and drop or click "Select File".
- Check the first-page preview to confirm you picked the right document.
- Choose your split method using the comparison table above.
- Enter a range if applicable — remember each comma-separated part becomes its own file.
- Split & Download — allow multiple downloads if your browser prompts.
Key Features
✂️ Split by Page or Range Extract every page individually or define custom ranges
🔒 Browser-Based Processing Your PDF stays on your device – no server upload
👁️ First-Page Preview Verify the right document before splitting
🔄 Multi-Part Ranges Enter ranges like "1-3, 5, 7-9" for multiple output files
Common Mistakes When Splitting PDFs
- Expecting "1-3, 5" to produce one file: it produces two — see the syntax table above.
- Ignoring the browser's blocked-download prompt: the split actually worked, but only the first file was saved.
- Entering a page number beyond the document length: this throws an error — check the total page count first.
- Splitting a password-protected file: this fails silently for that file; unlock it first.
Common Use Cases
- Extracting one certificate or marksheet from a bundled multi-document PDF.
- Separating a batch scan where each page is actually a distinct document.
- Sharing only relevant pages of a long report or contract.
- Splitting an e-book into chapter files for focused reading.
Troubleshooting
- Only one file downloaded: your browser blocked the rest — allow multiple downloads and retry.
- "Invalid range" error: use the format
1-3, 5, 7-9 — no spaces inside a range, comma between parts.
- Preview not showing: large PDFs take a moment to render the first page.
- Split fails entirely: the file may be password-protected or corrupted.
- Very large PDFs are slow: processing happens in browser memory, so large files depend on your device's available RAM.
Privacy and Security
Splitting runs on PDF-Lib inside your browser tab, with PDF.js handling the preview. Your files are never uploaded to any server, and everything clears when you close or refresh the page — which makes this suitable for legal, medical, financial and personal documents.

Frequently Asked Questions
Why did my browser block the downloads?
Splitting each page separately triggers one download per page, and most browsers block automatic multiple downloads by default. Allow multiple downloads for this site when prompted, or use Custom Range to produce fewer files.
How does the Custom Range syntax actually work?
Each comma-separated part becomes its own output PDF. So "1-3, 5, 7-9" produces three separate files — not one combined file of those pages.
How do I get several non-adjacent pages into one PDF?
Split them out with Custom Range first, then combine the resulting files using a PDF merge tool.
Can I split a password-protected PDF?
No — encrypted files can't be read without the password. Remove the protection first, then upload again.
Does splitting preserve quality and formatting?
Yes, pages are copied intact so fonts, layout and image quality are preserved exactly. Bookmarks and fillable form fields, however, are not carried over.
Is my PDF data secure?
All processing happens in your browser — files are never uploaded to any server.
Does it work on mobile?
Yes, though splitting into many files is more reliable on a desktop browser since mobile browsers handle simultaneous downloads poorly.
Is there a watermark on the output?
No, the output files are clean with no watermark or branding.
