About the Add image watermark
Handytool's image watermark tool overlays a custom text or logo on top of any photo in seconds. Pick a position, opacity, size and rotation, then apply the same watermark to a single image or an entire batch. Everything runs in your browser using the native Canvas API, so your photos and logos never leave your device.
Add image watermark features
- 01
Text or logo
Type a short tagline or upload a PNG logo with transparency. Mix a color, size and opacity until the watermark sits just right on your image.
- 02
Precise placement
Anchor the watermark to any of nine positions, fine-tune the padding and rotate it freely. Settings persist across the batch so the look stays consistent.
- 03
Batch with any format
Drop JPG, PNG, WebP, AVIF, GIF or HEIC photos and watermark them in parallel. Export in the original format or convert to JPG, PNG, WebP or AVIF in the same step.
Add image watermark FAQ
- How do I add a watermark to an image?
- Choose text or logo mode, enter your watermark, drop your photos onto the upload area, then click Apply. The watermark is composited directly in your browser and you can download each image or the whole batch as a ZIP.
- Can I watermark multiple images at once?
- Yes. Drop as many files as you like — the same watermark, position and opacity are applied to every image in parallel, then you can download them individually or as a ZIP.
- Does the watermark stay sharp at full resolution?
- Yes. The watermark is rendered at the native resolution of each input image, so text stays crisp and logos keep their transparency.
- What formats can I watermark?
- JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC/HEIF photos are all supported. The logo image can be PNG, JPG, WebP, AVIF, GIF or HEIC — PNGs with transparency work best.
- Is anything uploaded to a server?
- No. Watermarking runs locally using your browser's Canvas API. Your photos and logos never leave your device and nothing is stored.
