# Split PDF Online, Free

> A free online tool that splits a PDF into one file per page, per group of pages or per page range, or picks chosen pages into one new PDF, copying the pages as they are.

Split PDF files online by page, by range, or by picked pages, with this free PDF split tool. Upload one PDF, choose how to split it, and download the result as a ZIP or a single PDF. The pages are copied as they are, not re-encoded. Anonymous use needs a quick human check.

## Key facts

- Input: one PDF, up to 10 MB and 100 pages without an account (50 MB and 500 pages signed in); the type is read from the file content.
- Modes: every page as its own PDF, a new PDF every N pages (1 to 500), one PDF per page range (such as 1-3,4-6,7-z), or pick pages into one PDF in the order typed (such as 5,3-4,1). The result is a ZIP, or one PDF in pick-pages mode; a split makes at most 500 files.
- Page codes: z is the last page and r2 the second from last; a page past the end makes the job fail and returns the credits. In our test the ranges 1-2,3,4-z on a generated 6-page PDF gave a ZIP with three PDFs named part-001-pages-001-002.pdf, part-002-pages-003.pdf and part-003-pages-004-006.pdf.
- Encrypted PDFs are refused and are never opened or broken; a slightly damaged PDF is repaired automatically and the result panel says so, unless repair is turned off.
- API: POST the PDF to https://api.aiipworld.com/v1/uploads, then POST https://api.aiipworld.com/v1/pdf-jobs with op pdf_split (mode each, every or ranges) or pdf_extract (pages), and poll GET /v1/jobs/:id.
- Free without an account: 20 PDF jobs per day per visitor, no watermark. Signed in, each job costs 1 credit plus 1 credit for each started 20 MB of result beyond the first 20 MB (100 free credits every month).
- Files are deleted automatically: 10 minutes after conversion without an account, 1 day with a free account.

## How it works

1. Upload one PDF.
2. Choose a split mode under "How to split".
3. Type page numbers if the mode needs them, for example 1-3,4-6,7-z.
4. Click Split PDF.
5. Download split-pages.zip or extracted-pages.pdf.

## How to split a PDF online

Start by uploading one PDF. The tool reads the file's first bytes to confirm it is a PDF, so a file with a renamed extension is treated as what it really is. Then pick one of the four modes and set its pages if the mode needs them. You can split PDF by pages, by ranges or by a fixed number of pages.

Click Split PDF to run the job. When it finishes, the result panel shows how many pages went in and how many PDFs came out, along with the size and the credits reserved. Download the file from the panel.

## PDF splitter: separate PDF pages or split PDF pages in blocks

This PDF splitter cuts one PDF into parts, and it works on one file at a time. To separate PDF pages into single files, choose "Every page into its own PDF (ZIP)". To split PDF pages into fixed blocks, choose "A new PDF every N pages (ZIP)". As a PDF page splitter it can also cut by ranges, such as 1-3,4-6,7-z. The pages are copied, not edited.

## Four ways to split: every page, every N pages, ranges, or pick pages

The tool offers four choices under "How to split". Use "Every page into its own PDF (ZIP)" to get one file per page. Use "A new PDF every N pages (ZIP)" with N from 1 to 500 to group pages into fixed blocks.

"Page ranges, one PDF for each range (ZIP)" builds one file per range you type, such as 1-3,4-6,7-z. "Pick pages into one PDF, in the order you type" builds a single new PDF from the pages you list, such as 1-3,5,r1.

## Split a PDF by page ranges

Ranges mode turns every comma-separated item into its own PDF. The input 1-3,4-6 makes two files, and a single number such as 5 makes a one-page file. Use a dash for a span and z for the last page.

Ranges are useful when you want chapters or sections as separate documents. Keep the list to 200 items or fewer.

## Extract pages from PDF files into one new PDF

Pick pages mode gives you one PDF made only from the pages you name. It is the right choice when you need a few pages, not a full set of parts. Type the pages you want, separated by commas, and the tool returns extracted-pages.pdf.

Pages are kept in the order typed, and a page can appear more than once. The result is still limited by the page limit for your account.

## How to extract pages from PDF files in three steps

Upload one PDF. Under "How to split", choose "Pick pages into one PDF, in the order you type". Type the pages you want, such as 2,5-7, and click Split PDF. You get extracted-pages.pdf with only those pages, so you can extract PDF pages without keeping the rest of the file.

## Reorder pages with the pick-pages mode

Pick pages mode also reorders. The input 5,3-4,1 gives page 5, then pages 3 and 4, then page 1. In our test, the same 6-page generated PDF gave a 4-page result in exactly that order.

Reordering only changes the sequence of pages in the new file. Pages are not edited. If you need a full reorder of a long document, check the output page by page before you rely on it.

## What the ZIP contains and how the files are named

Most split modes return a ZIP file named split-pages.zip. Every page mode uses names such as page-001.pdf. The every-N mode uses names such as pages-001-004.pdf, with the numbers padded to the length of the page count. Ranges mode uses names such as part-001-pages-001-002.pdf.

The ZIP is stored without compression because PDF pages are already compressed. In our test, a 6-page generated PDF of 124 KB split with the ranges 1-2,3,4-z gave a 125 KB ZIP with three PDFs. Sizes will vary with your file.

## Page numbers that do not exist

Page numbers start at 1, and zero is not valid. If you type a page past the end of the document, the job fails with a message such as "N is outside the document, which has M pages". The credits for that job are returned.

In our test, page 9 on a 2-page generated PDF failed this way. Check the page count in your file before you run the job, especially when you use z or r-numbers.

## Limits: size and pages

The free web tool allows up to 10 MB per file and up to 100 pages. Signed-in users get up to 50 MB per file and 500 pages. Without an account the file is uploaded with a human check, and each upload counts toward 40 uploads per day for each visitor.

The web tool allows 20 jobs per day for each visitor. A split can make at most 500 files, and a result can be up to 200 MB. The time limit is 30 seconds for an anonymous job and 60 seconds for a signed-in job.

## Encrypted and damaged files

Encrypted PDFs are refused. This includes files that are password protected or have permission restrictions, whatever the strength. No password is accepted, and the tool makes no attempt to open or break the protection.

A slightly damaged PDF is repaired automatically when possible, and the result panel says so. The option "Repair a slightly damaged PDF automatically" is on by default. If you turn it off, a damaged file is refused. A file that cannot be repaired is refused as well.

## What to check in the result

Check the page count first. The result panel reports pages in and out, and the file count. For a split, the counts should match the ranges or the page numbers you typed. The tool also checks the page count after writing and refuses a result that does not match.

Open a few of the output files. If your PDF has bookmarks, links, form fields, tags or metadata, check them, because those features have not been tested. Results vary by file, so do not assume a result is right without a look.

## Split a PDF from code

The API takes one PDF per job. First send the file as raw bytes with Content-Type application/pdf to https://api.aiipworld.com/v1/uploads. The answer contains an upload_id. Then send a JSON body with op, params and files to https://api.aiipworld.com/v1/pdf-jobs. For a split, use op pdf_split with params mode set to each, every (with every from 1 to 500), or ranges (with ranges). For "pick pages", use op pdf_extract with params pages.

Authorize with a Bearer token or the x-api-key header. Poll GET /v1/jobs/:id until the job finishes. Split returns a ZIP. Errors include 400 invalid_params, 413 file_too_large, 422 not_a_pdf, 404 upload_not_found, 402 insufficient_credits and 429 for rate limits. A failed job can return error_codes such as encrypted_pdf, corrupt_pdf, too_many_pages or page_out_of_range. The page shows a ready cURL, Node and Python example built from your settings. See /docs/ for the general API.

## Privacy: what happens to your file

Your file is sent to our server, because nothing is processed in the browser. The file is used only to make the result. The working copy of your upload is deleted as soon as the job ends, whether it succeeds or fails.

In the free web tool, the result is deleted after 10 minutes, and the result panel shows how long it is kept. No history is kept. Download links are short-lived, so save the file when it is ready. You must have the right to use the files you upload, as the Acceptable Use Policy requires.

## Questions

### Can I split a PDF for free?

Yes, the web tool is free and needs no signup. Anonymous use has the limits listed on this page and needs a human check.

### How do I split a PDF into single pages?

Choose "Every page into its own PDF (ZIP)" and click Split PDF. You get a ZIP with one file per page, named page-001.pdf and so on.

### How to separate a PDF by page?

Choose "Every page into its own PDF (ZIP)" and click Split PDF. Each page becomes its own PDF in a ZIP. To separate by groups of pages instead, use the every N pages mode or the page ranges mode.

### How to split PDF files into smaller parts?

Upload one PDF, choose a mode under "How to split", type page numbers if the mode needs them, and click Split PDF. You can split every page, every N pages, or by ranges, or pick pages into one new PDF.

### How do I split a PDF by page ranges?

Choose "Page ranges, one PDF for each range (ZIP)" and type ranges such as 1-3,4-6,7-z. Each range becomes its own PDF inside the ZIP.

### How do I extract pages from a PDF?

Choose "Pick pages into one PDF, in the order you type" and list the pages, for example 1-3,5,r1. The result is one new PDF called extracted-pages.pdf.

### Can I change the order of the pages?

Yes, in pick pages mode. Pages come out in the order you type, so 5,3-4,1 gives page 5, then 3 and 4, then 1. A page can appear more than once.

### Why did I get a ZIP file?

Every page, every N pages and ranges modes make several files, and a ZIP keeps them together. The ZIP is stored without compression, so its size is close to the total of the PDFs inside.

### What does the last page code z mean?

The code z means the last page of the document. For example, 4-z means page 4 through the last page. The code r1 means the last page too, counted from the end.

### What happens if I type a page that does not exist?

The job fails with a message saying the page is outside the document and how many pages it has. Your credits are returned. Check the page count before you run the job.

### Does splitting reduce the quality?

Splitting copies the pages as they are and does not re-encode them. Text, fonts and images keep their quality. Check the output if your file has special features, because those have not been tested.

### Can I split a password-protected PDF?

No. Encrypted PDFs are refused, whether they are password protected or have permission restrictions. No password is accepted, and the tool makes no attempt to open or break the protection.

### How many pages can I split?

The free web tool allows up to 100 pages without an account. Signed-in users can split up to 500 pages. A split can make at most 500 files.

### Can I split a PDF in my own code?

Yes. Upload the PDF to the uploads endpoint, then create a pdf-jobs request with op pdf_split. The page shows ready examples, and /docs/ has the general API details.
