What to expect
Place adjustable text watermarks on local images, including opacity and tiled patterns. Protect previews or label images with center, corner or tiled text watermarks.
Limitations and image privacy
Text watermarking does not enforce copyright or prevent cropping. Text and logo overlays are available, but do not reliably prevent copying or re-encoding.
Each file is capped at 20 MB and 30 million decoded pixels. Multiple files are processed sequentially to limit CPU and memory demands. Files are processed locally; nothing is transmitted to the image-processing server. Generated copies can differ from the original and original files remain on your device.
