Frequently Asked Questions
Will image quality decrease after watermarking?
If you choose PNG format, there is no quality loss. JPEG or WebP formats have slight compression but minimal visual impact.
Will my images be uploaded to a server?
No. All image processing is done locally in your browser. Your image data never leaves your device, ensuring complete privacy protection.
What types of watermarks are supported?
Text watermarks and image watermarks are supported. Text watermarks allow custom content, color, size, and rotation. Image watermarks let you upload a custom logo or icon.
What is the difference between single and tiled watermark?
Single watermark places one watermark at a chosen position (9-grid selection). Tiled watermark repeats the watermark across the entire image, ideal for anti-theft scenarios, with customizable spacing.
Can I watermark multiple images at once?
Yes. Upload multiple images simultaneously, apply watermarks in batch, and download all processed images at once.
Is this watermark tool free to use?
Completely free. This is a pure frontend online tool — no registration required, no payment needed, just open and use.
