Frequently Asked Questions
How many images can I batch watermark at once? ▾
Up to 20 images per batch. Each image is processed using your device's CPU and memory. Very large images (10MB+) may take a few seconds each. There's no artificial server-side limit — only your device's available memory.
Are my images uploaded to a server? ▾
No. All processing happens entirely in your browser. Your images are never transmitted to any server. The tool uses the HTML5 Canvas API locally — it even works offline once the page is loaded.
Can I download all watermarked images at once? ▾
Yes! After watermarking, click "Download All as ZIP" to get a single ZIP file containing all your watermarked images. You can also download each image individually using the download button next to each file.
Can I use different watermarks for different images? ▾
The batch mode applies the same watermark configuration to all images. For different watermarks per image, use the single-image tool at add-watermark-to-image.html — each image can be processed individually.
