Watermark Options
Text Watermark
Your own text in the color you pick, at the size and opacity you set. Add a © symbol, your name or your URL.
Logo Overlay
Place your PNG logo on every photo. Supports transparency for professional results.
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.

Yes. Contenta supports 30+ RAW formats from Canon, Nikon, Sony, Fuji, Panasonic, Olympus, and more. Full white balance, denoising, and color adjustment controls are built in.
Every feature, every file and no time limit. Each batch converts in full; results carry a small watermark until you pick up to 10 of them to keep clean. Those picks count once per PC, not per batch, and a batch of 500 costs none until you choose. A license ($129 once) removes the watermark from everything you convert.
No. Contenta Converter is a one-time purchase. You pay once and own it forever, including all future updates. No monthly or yearly fees.
