Protect visuals before they travel
Image Watermark Studio
Add polished text watermarks without leaving the browser. Dial in fonts, opacity, drop shadows, and placement, then download an export-ready image instantly.
What this tool covers
Each mini tool is purpose-built, runs entirely in your browser, and is engineered for practical, everyday tasks.
- Zero back-end calls — everything stays local.
- Clean download/export flows with sensible defaults.
- Cross-device friendly layouts with actionable guidance.
1. Choose your base image
Nothing uploads—everything runs on <canvas>. Large PNG, JPEG, and WEBP files welcome.
Status
Upload an image to start watermarking.
2. Design your watermark
Pick typography, size, color, and effects that match your brand. Adjust opacity for subtle overlays.
Placement
Center placement works well for social teasers. Corners are better for unobtrusive brand marks.
3. Preview & export
Apply the watermark, review the preview, then download. Your original pixels stay untouched.
Watermark tips
- • Keep opacity between 40–70% so the watermark is visible but not distracting.
- • Use rotation for large diagonal overlays when images get reposted often.
- • Save a template text string by bookmarking this URL with a query param.
