Image Overlay
Lay one image over another and blend them with a choice of fourteen blend modes, including multiply, screen, overlay, soft light and difference. Upload the base image first and the overlay second, choose how the overlay is fitted to the base and set its opacity. Use it for textures, light leaks, frames, double exposures or color washes, and download the result as PNG, JPEG or WebP.
Frequently asked questions
Which image goes first?
Upload two images together: the base image first and the overlay second. The result always has the size of the base image, and the overlay is fitted onto it.
Which blend modes are available?
You can choose normal, multiply, screen, overlay, darken, lighten, color dodge, color burn, hard light, soft light, difference, exclusion, add and saturate. They follow the standard compositing formulas of the libvips image library.
Which blend mode should I use for a texture?
Overlay and soft light add texture while keeping the base image's contrast, multiply darkens with the overlay's dark parts, and screen lightens with its bright parts. Screen works well for light leaks and bokeh shot on black.
How is the overlay fitted to the base image?
Cover scales the overlay to fill the base and crops the excess from the center, contain fits it inside with transparent space around it, and fill stretches it to the exact size. Original size centers the overlay without scaling and crops it if it is larger than the base.
What does the opacity setting change?
Opacity from 1 to 100 percent scales the transparency of the overlay before it is blended. Lower values give a subtler effect with any blend mode.
Does transparency in the overlay matter?
Yes. Transparent parts of a PNG, WebP, GIF or AVIF overlay leave the base image untouched, so you can place frames or cut-out graphics with any blend mode.
Which formats are supported?
Both images can be JPEG, PNG, GIF, WebP, TIFF or AVIF. The download is a PNG by default, or JPEG or WebP at quality 90, and JPEG output fills transparent areas with white.
What are the size limits?
Each file can be up to 5 MB and both together up to 12 MB. A base image larger than 4000 pixels on a side is scaled down to fit within 4000 pixels.
Can I create a double exposure?
Yes. Upload a portrait as the base and a landscape as the overlay, then try screen or lighten with cover fit and an opacity around 70 percent for the classic double exposure look.
Are animated images supported?
Only the first frame of an animated GIF or WebP is used for each image. The result is a single still image named after the base image.
