## What this tool does
Stamp your text watermark across a batch of photos — proofing, drafts and previews protected.

## Typical user problems
- Design proofs, event photos and previews get lifted the moment you send them unprotected. Manual watermarking in an editor for dozens of files is an hour of clicking — this is one upload.
- Sending unwatermarked proofs means clients "accidentally" use them without paying. Stamp every proof with your studio name before it leaves your machine.

## Parameters
- text: string, required. 水印文字. 如：草稿 / DRAFT / 你的名字
- opacity: number (range 0.05-0.6), optional. 不透明度

## 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
- 1-30 images per task, up to 50 MB each
- Single diagonal text stamp, PNG/JPG in → JPG out
- Opacity 5%-60% configurable
