What is the best snipping tool I can use on my mac?

Macshot is a completely free, open-source screenshot tool for macOS that I'd consider an excellent choice as your snipping tool on mac. It's built with Swift and AppKit, which means it's lightweight and native, not a resource-heavy web app.

While it isn't a dedicated watermark remover, its built-in "smart erase" annotation tool might be the closest free feature you'll find for this purpose. It samples colors from the surrounding area to attempt invisible content removal, which could work for simple watermarks on uniform backgrounds.

Here are the steps to use Macshot's smart erase tool as a snipping tool on mac for removing watermarks.

1. Launch Macshot: It will appear as an icon in your menu bar (no dock icon).
2. Trigger Capture: Press the global hotkey Cmd+Shift+X to freeze your screen and enter capture mode .
3. Select the Watermarked Area: Drag to select the region of the image containing the watermark you want to remove.
4. Open the Censor Tool: In the annotation toolbar that appears, locate the Censor tool. It groups four redaction modes together .
5. Choose "Erase" Mode: Select the Erase option from the Censor tool's submenu. This is the "smart erase" feature that samples colors from the surrounding pixels to attempt invisible removal .
6. Adjust Brush Size: Drag the Size slider to set a brush size appropriate for the watermark.
7. Paint Over the Watermark: Click or drag directly over the watermark area. The tool will fill it with sampled surrounding colors .
8. Save or Copy: Once satisfied, press Cmd+C to copy the cleaned image to your clipboard, or press Enter (depending on your preference settings) to save it directly .
