How do I add a watermark to an image online for free?

Upload your image to ZapFile's Watermark tool, type your watermark text, adjust the position, opacity, and size, then download the watermarked image.

Can I watermark multiple images at once?

Yes. ZapFile's watermark tool supports batch processing — upload multiple images and apply the same watermark settings to all of them.

The watermark is burned into the downloaded image. ZapFile does not store originals or watermarked versions anywhere.

Yes, all ZapFile tools are completely free with no hidden costs or subscriptions.

Absolutely. All processing happens directly in your browser. Your files are never uploaded to any server.

No. ZapFile requires no registration, login, or account creation.

Supported formats are listed on each tool page. We support all major file formats.

Since processing happens in your browser, the limit depends on your device's memory. Most files up to 500MB work fine.
