How to Add a Watermark to a Screenshot on Mac (2026)
Add an image watermark (your logo or mark) to any Mac screenshot in seconds with Pizazoo. Free, on-device, non-destructive. Step-by-step guide.
You shouldn’t need Photoshop to put your name on a screenshot before posting it. Here’s how to do it on Mac in two minutes.
Step-by-step
Step 1: Open the screenshot in Pizazoo
Find the screenshot in your Pizazoo library, open it (Return or Space opens the preview), then click Edit to open the markup editor.
Step 2: Pick the Watermark tool
Click Watermark in the markup toolbar. Click Add to import an image (a PNG with transparency works best; JPEG, TIFF, and HEIC also work). It is saved as a reusable watermark.
Step 3: Set position, size, and opacity
Pick a corner or the center (or drag it anywhere), then set size and opacity (10–30% is typical for "visible but not annoying").
Step 4: Click Done
Click Done to apply the watermark. Pizazoo keeps the pristine original, so you can reopen the editor later and change or remove it. To keep both versions, open the Done menu and choose Save a copy.
Tips
- For social-media screenshots, a corner watermark at ~20% opacity is enough to signal ownership without being ugly.
- For "do not screenshot" use cases (early design proofs, client-only previews), place a larger watermark in the center at higher opacity, which is much harder to crop out.
- Want a text watermark? Save your name or handle as a transparent PNG once and import it, or add it with the Text tool.
- Pizazoo also supports signatures if you want a handwritten mark instead; see the signature guide.
