Watermark Image FAQ
Enter your watermark text before choosing files, then select multiple JPG, PNG, or WebP images. The same repeated text treatment is applied to every selected image in your browser
Yes. The tool repeats the text diagonally across the complete image instead of placing a single watermark in one corner

Yes. You can select multiple supported images, process them as one browser-local batch, and save successful results individually or together as a ZIP
The tool supports tested still JPG, JPEG, PNG, and WebP images
No. Selected images, full file names, decoded image content, generated images, and ZIP files remain on your device and are not uploaded for processing. The page may still make ordinary website requests
No. Watermark text is not included in processing requests, analytics, URLs, feedback, or application logs
Images already selected keep the watermark text captured when they were added. Updated text applies only to images selected afterward
Yes. Text size is calculated from the image's short edge, so the watermark keeps a consistent visual proportion without stretching the letters

Yes. Plain Unicode text is supported, although exact glyph appearance can vary with the fonts available on your device and browser
No. This tool is designed specifically for repeated plain-text privacy watermarks
No. Capture time, location, color profiles, and other metadata are not copied, and animated images are not preserved as animations
