## What this tool does
Split a large PDF into ordered parts by page count or per-file size — nothing lost, nothing duplicated.

## Typical user problems
- Oversized PDFs get bounced by email systems and upload forms alike. Splitting by hand means re-saving ranges in a desktop tool — page ranges you will probably get wrong under time pressure.
- The 25 MB email limit rejects your 60 MB PDF. Split it into ≤10 MB parts that each send cleanly — named part-01, part-02 so the receiver keeps the order.
- Upload portals take one page per field (ID front, ID back…). You need every page as its own file, numbered, in seconds.

## Parameters
- mode: enum, required. 拆分方式
- n: number (range 1-500), optional. 每份页数 N
- target_mb: number (range 0.1-500), optional. 每份大小上限 (MB)

## 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
- Max input 200 MB / 500 pages
- Output: zip of numbered PDF parts
- Size-based split is approximate ±5% (verified under cap)
