Watermark a whole folder of photos before you share them — text or logo, in one batch
Watermark thousands of photos in one batch: text or logo, 9 positions, your size and opacity.
Protect your work before you share it. Each photo gets one watermark: your text or your logo. Pick one of 9 positions, a size from 5 to 100% of the photo width and an opacity from 0 to 100%.

Position Control
9-point grid: the four corners, the middle of each edge, or the center of the photo.
Opacity & Size
Opacity from 0 to 100%. Size from 5 to 100% of the photo width, so the watermark keeps the same proportion at every resolution.
Before & After
Before Contenta
Open each photo in Photoshop. Add text layer, position it, adjust opacity, flatten, export. Repeat 1,000 times. Hours of repetitive work.
After Contenta
Drop 1,000 photos into Contenta. Set your text or logo watermark once: position, size, opacity. Click Convert. Every photo gets the same watermark, with no work per photo.

The 30-day trial includes every feature. The first 10 images you convert are saved without a watermark. That allowance is counted once across the whole trial, not per batch, so conversions after it carry a small watermark. A license removes it.
