Free Watermark Image
Add verified text, logo, or mosaic watermarks to static and animated images with adaptive contrast and batch reports. A temporary copy uses the best available open-source processor, and the result is decoded again before download.

How it works
- Try the local sample or add up to 100 JPG, PNG, WebP, AVIF, HEIC, GIF, TIFF, or safe SVG sources; camera EXIF orientation is normalized before marking
- Build text, logo, or aligned text-and-logo marks with filename, date, width, and height tokens; uploaded logos are decoded, dimension-limited, metadata-stripped, and never retained
- Choose adaptive light/dark contrast or brand colors, then tune font, scale, opacity, outline, shadow, backing, padding, gap, and rotation
- Place one mark in nine anchors or at exact X/Y coordinates, or protect the full canvas with a staggered mosaic; orientation filters can target portrait or landscape sources
- Keep compatible source formats or deliver JPG, PNG, WebP, or AVIF with predictable names; animated GIF and WebP inputs preserve every frame, delay, loop, and alpha channel, while TIFF pages remain separately named
- Every output is independently checked for visible overlay pixels, placement, dimensions, animation structure, timing, private metadata, clean decode, transfer integrity, and archive reopen; batch ZIPs include text and JSON reports
Short-lived by design
Files are processed in an isolated temporary workspace that is deleted when the result finishes streaming or the job fails. Nothing becomes an account file.
