How to Watermark Photos in Bulk
- 1 Install the app on Windows or macOS.
- 2 Type your copyright text or load a logo PNG, then set position, angle, size and opacity - or tile it diagonally across the whole image.
- 3 Point it at a folder and stamp every photo in one pass; export at full resolution with no added mark from the tool itself.
Why Watermark Before You Publish
Once a photo is online it gets copied. A visible, hard-to-crop watermark discourages theft and points users back to you - and doing it locally means you never hand your originals to a third-party site.
Text or logo watermark
Use a copyright line, a brand name, or a transparent PNG logo.
Corner or full-tile
Tuck it in a corner, or tile it edge-to-edge so it can't be cropped out.
Adjustable opacity & angle
Keep it legible without ruining the picture; rotate to any angle.
Batch a whole folder
Apply the same watermark to hundreds of product or portfolio photos at once.

Desktop Watermarking vs Online Sites
The difference is mainly privacy and volume.

Frequently Asked Questions
How do I add a watermark to many photos at once?
Set up your text or logo once, then select a folder; the app stamps every image in that pass with the same position, opacity and angle - handy for product shots or a photo portfolio.
Can I tile the watermark so it can't be cropped out?
Yes. Place it in a corner, or tile it diagonally across the whole frame so removing it by cropping is impractical.
Does the tool add its own watermark on the free version?
No. Your export is your photo plus the watermark you chose, at full resolution - unlike online services that stamp their own logo on the free tier.
Are my photos uploaded?
No. Watermarking runs entirely on your Windows or macOS machine; nothing is sent anywhere.
Is it free?
It is free to download and try on your own photos; after the trial it is a one-time purchase, not a subscription.
