## What this tool does
Split an oversized PDF into volumes under your model's upload limit — page-aligned, ordered, zipped.

## Typical user problems
- Every AI assistant, portal and email client has its own upload cap, and your 300-page document does not care. Pages are accumulated into volumes until the next page would exceed the target size, then a new volume starts — every volume is a valid standalone PDF and page order is preserved across the set.
- Chat assistants cap uploads (512 MB, 100 MB, 20 MB — pick your poison). A 400-page manual or a year of statements will not go through as one file, and page-range splitting by hand takes forever.

## Parameters
- target_mb: number (range 0.01-500MB), optional. 每卷目标大小上限. 按页累计切分（每页大小按文件总量比例估算）

## Pricing
- Watermarked preview: free, no login required
- Final clean output: $0.99 one-time per task
- Require login (email/phone OTP) to complete payment
- Result available for download 24 hours after payment

## Limitations
- Splitting is page-aligned — a huge page cannot be divided further
- Size estimate is proportional (not per-object exact)
- Output is a zip of PDFs even when everything fits in one volume
