FAQs
Are my images uploaded to a server?
No. Watermarking runs entirely in your browser using the Canvas API, so your images never leave your device.
Can I watermark several images at once?
Yes. Add multiple images and the same watermark settings are applied to every one of them in a batch.
Can I use my own logo as a watermark?
Yes. Switch to the Logo image option, choose your logo, and it is scaled to about 20% of the image width while keeping its aspect ratio.
Is the tool free to use?
Yes. Every Handio tool is free, with no sign-up, no limits and no watermarks added by us.

Why watermark your images?
Watermarks label your work and discourage casual reuse when you share photos online. A subtle mark protects your brand without ruining the image.
- Protect product and portfolio photos before posting them publicly.
- Stamp your brand or copyright line across every export.
- Batch-watermark a whole shoot in one click instead of one file at a time.
Tips and Limits
Keep opacity around 40-60% so the watermark is visible but the image stays readable. The watermark is drawn onto a copy of your image, so the original file on your device is never changed. Everything is processed locally in your browser.
