Frequently Asked Questions
What is Image Watermark and how does it work?
Image Watermark is a free online tool that adds text or logo watermarks to your images. Protect your photos, brand your content, or add copyright notices instantly.
Is my image uploaded to a server?
No. All watermarking happens entirely in your browser. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
This tool accepts PNG, JPEG, WebP, GIF, and BMP images. Export your watermarked images in PNG, JPEG, or WebP format.
Are there file size limits?
Yes, the maximum file size is 50MB per image. If you upload a file larger than 50MB, you'll see an error message: "File too large. Maximum size is 50MB." For best performance, we recommend keeping images under 20MB. Batch processing supports up to 50 images at once. If you have very large images, consider using the Image Resizer tool first to reduce dimensions.
Can I add both text and logo watermarks?
Yes! Choose between text watermarks (customizable font, size, color) or image/logo watermarks. Position and adjust opacity for perfect results.
Is this tool really free?
Yes! This watermark tool is completely free with no hidden costs, watermarks on your images, or signup requirements.
Can I watermark multiple images at once?
Yes! Use batch mode to apply the same watermark to up to 50 images simultaneously. Download individually or as a ZIP archive.
How do I position my watermark?
Drag the watermark directly on the preview to position it precisely. Choose from preset positions or set custom X/Y coordinates for exact placement.
How do I download watermarked images?
After adding your watermark, click the Download button to save the watermarked image. For batch processing, download individually or click "Download All as ZIP". Files save to your device's default download folder.
Does this work on mobile/phone?
Yes! The Watermark tool works perfectly on iPhone, Android phones, and tablets. The interface is fully responsive and touch-friendly, so you can add watermarks on the go.
How long does processing take?
Processing is instant! Watermarking typically takes 1-5 seconds per image depending on file size and your device speed. Larger images (20MB+) or batch processing may take 5-10 seconds. Since everything runs in your browser, speed depends on your device's performance.
What browsers are supported?
This tool works on all modern browsers: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+, and Opera. It also works on mobile browsers including Safari on iOS and Chrome on Android. For best performance, keep your browser updated.
