Can I specify a page range to split a PDF?

Yes. Use the `pages` parameter to specify individual pages or ranges — for example `1,3,5-7` extracts pages 1, 3, 5, 6, and 7 into a single output PDF. You can combine comma-separated pages with dash-delimited ranges in any order.

What is the maximum file size supported?

Limits depend on your plan and are enforced per API key — the API reports the ceiling it currently accepts at https://api.convertfilefast.com/v1/info, and your own plan limit is shown in your dashboard. If a file exceeds it, compress it first with the Compress PDF endpoint.

Does the API return a ZIP file when splitting into multiple parts?

No. Each API call returns a single PDF containing the pages you selected. If you need to extract multiple separate sections, make one API call per section. The response Content-Type is always `application/pdf`.

How many splits can I perform per API call?

Each API call produces one output PDF. There is no limit on how many pages you select per call. To split a document into N independent parts, send N requests — each request counts as one conversion against your monthly quota.

How it works

4 steps to run this conversion

1
Create an API key
Sign up at convertfilefast.com/signup and copy your cff_ API key from the dashboard. The free tier includes 10 conversions per month.
2
POST the PDF to the endpoint
Send a multipart/form-data POST to https://api.convertfilefast.com/v2/pdf/split with header X-API-Key: cff_your_key (Authorization: Bearer also works), the PDF as a file field or a public url field, and a pages field such as 1,3,5-7.
3
Receive the PDF
The response body is the resulting PDF, streamed back with a Content-Disposition filename. Save it or pass it straight to the next step of your pipeline — nothing is stored on our side.
4
Or invoke it from an AI agent
Add the MCP server to Claude, Cursor or any MCP-compatible client using https://mcp.convertfilefast.com/mcp, then call split_pdf({ source_url: '...', pages: '1,3,5-7' }) as a single tool call — no HTTP client, no file handling.

For AI agents

Or call this from Claude, Cursor, or any MCP client
