Add Logo online

Placing a logo by hand on each photo gives slightly different sizes and positions. Here the size and margin follow the same rule every time.

Choose the photo first and the logo second. Dropped and pasted images are added to the ones already open, so you can open the photo and then drop the logo onto it. Picking with the button again replaces the set, so select both files together if you use it. The logo is scaled, keeping its proportions, until it fits within 28% of the photo's width and 28% of its height, then placed 24 pixels from the right and bottom edges.

Overlay opacity runs from 0 to 100% and starts at 55%, which reads as a soft watermark. Raise it to 100% for a solid logo. The 24 pixel margin is fixed in real pixels, so on a large camera photo the logo sits very close to the corner. A logo with a white box behind it will show that box; use a transparent PNG.

Add Watermark writes text instead of an image, which is quicker if your brand is just a name. Image Overlay stretches a second image across the whole photo rather than a corner. To brand an animated GIF, use Add Image to GIF, which puts the image in the same corner of every frame.
