How to use
Up to 20 files, 10 MB each, 50 MB total. PNG, JPEG and WebP images up to 16 megapixels. Image output is a still image; image metadata is not preserved. The file renamer preserves original file contents.
Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
Batch Image Watermark: Add Logo to 20 Photos
Adding a watermark helps deter unauthorized use of property photos shared online. Add a logo or text to up to 20 images at once, adjust opacity and position. Everything runs in your browser. A watermark deters copying but never gives full protection.

Where can you use this on social media?
YouTube
Prepare a 16:9 frame for a YouTube video thumbnail, then check text readability and file size. Compressing an image does not compress a video.
Instagram
Prepare square or 4:5 artwork for an Instagram post, or 9:16 for a story. These are working options. Check cropping in the profile grid and app before posting.
TikTok
Prepare a 9:16 photo or vertical cover for TikTok. Keep titles away from edges where app controls may overlap. Image tools do not produce videos.
Facebook
Use images in Facebook posts, product pictures or link sharing. A 1200 × 630 working canvas is an option for link images; check the final view on phone and desktop.
