About the Watermark Image
Overlay a text or image watermark on your photos with adjustable position, size and opacity, then export — all locally.
Watermark Image is part of a free, privacy-first toolkit. Everything is processed locally on a Canvas with high-quality pica resampling — there are no uploads, no quality loss from a server round-trip, and no limits.
Because watermark image works without any sign-up or installation, you can use it as often as you like and it's always available — on desktop or mobile, and even offline.
