How to use
Select exactly two files together: base image first, logo second. The selection summary shows the order. Set logo width and placement.
Limits and behavior
The logo keeps its aspect ratio and must fit the base image. Browser canvas scaling is used. Still PNG, JPEG and WebP only; 20 MB, 4 megapixels and 4,096 pixels per side. Processing stays on your device. Exports apply orientation and discard source metadata. PNG output preserves transparency unless the selected operation composites it.
Composite a logo over a picture
Use a selected logo image as a watermark over a base image. This is useful for branding marketing assets and marking design previews.
Does a logo watermark prove copyright ownership?
No. A visible logo is not independently verifiable proof of authorship. Preserve original source files and licensing records.
