Watermarking
Watermark Opacity Tester
Renders the same watermark on your photo at six opacity levels so you can judge where it stops being visible and starts being annoying.
Pick something with both flat areas and busy detail — that's where opacity choices actually get decided.
Your file is processed on the server and deleted as soon as the result is rendered. Nothing is stored, logged or shared.
Got a whole shoot to get through?
Send one photo and I'll watermark it for free, so you can judge the quality before handing over the batch.
