Adding the same watermark to dozens or hundreds of photos one by one is tedious and time-consuming. Batch watermarking applies your copyright or brand mark to all photos simultaneously — a task of hours compressed into minutes.
When Bulk Watermarking Is Needed
- Preparing a full photo gallery for client review
- Uploading product photos to an e-commerce store with brand marking
- Protecting an entire social media image library
- Adding "DRAFT" or "FOR REVIEW" stamps to multiple document pages
- Protecting a photography portfolio before publishing online
How to Watermark Photos in Bulk Free
Visit imgresizr.com and upload multiple photos at once. Configure the watermark: text or logo, position, opacity, and font size. Apply to all photos simultaneously. Download all watermarked photos as a ZIP archive. Every photo receives the same watermark at exactly the same position, size, and opacity — ensuring consistent branding across your entire collection.
Bulk Watermarking Settings to Standardise
| Setting | Recommendation for Consistency |
|---|---|
| Position | Fixed corner or centre — same across all images |
| Opacity | 30–40% — consistent protection |
| Size | Percentage-based, not pixel — scales with image size |
Tips for Professional Bulk Watermarking
- Use a percentage-based watermark size so it scales proportionally to different image dimensions
- Test the watermark on one image before processing the full batch
- Keep the original unwatermarked files in a separate folder
- Name the ZIP download clearly (e.g., "Client-Gallery-Watermarked.zip") for organisation
