Batch Watermark Maker for brand protection
Batch Watermark Maker helps sellers and agencies apply consistent text or logo marks before publishing product images, marketplace photos, or client previews.
Watermarking runs in the browser, so unreleased product photos and client files stay local.
How to watermark photos in bulk
- Add JPG or PNG photos.
- Set text watermark copy or upload a transparent logo.
- Adjust opacity, size, padding, and position.
- Preview the first image, process the batch, and download a ZIP.
Watermark format guidance
JPG is broadly compatible for marketplace photos. PNG is useful when preserving transparency or crisp logo edges matters.
| Decision | Best fit | Why it matters |
|---|---|---|
| Text watermark | Short brand or proof label | Readable marks stay clear across thumbnail sizes. |
| Logo watermark | Transparent PNG | Keeps the logo edge clean over product photos. |
| Output review | Preview before batch | Small opacity changes can affect every file. |
Private browser-side processing
The canvas composition and ZIP preparation happen locally. API routes handle access and payments only.
Workbench and access
The Workbench is useful when agencies apply the same logo, opacity, and placement across recurring client batches.
Guests can try tools within the configured hourly limit. Coffee unlocks one tool, Lunch unlocks the suite, and Solutions adds workflow building and sharing.
