How to use Image Overlay
- 1
Upload the base image
Drop the image you want to use as the background onto the "Base image" drop zone.
- 2
Upload the overlay image
Drop the image you want to composite on top onto the "Overlay image" drop zone.
- 3
Choose a blend mode and opacity
Select a blend mode from the dropdown. "Normal" is a simple alpha composite; "Multiply", "Screen", and "Overlay" create different tonal effects. Set opacity to control the strength of the overlay.

What blend modes do
A blend mode determines how two images interact at each pixel rather than one simply covering the other. Multiply darkens the result - useful for adding texture from a paper or film scan to a photograph. Screen lightens - useful for adding light leaks or glow effects. Overlay increases contrast while mixing colors from both images, creating a punchy combined result. The visual output changes dramatically depending on both the blend mode and which image is on top.
Double exposure is one of the most popular uses: two photographs combined at reduced opacity with a blend mode create the impression of a single frame exposed twice. This technique appears in portrait photography, editorial design, and social media creative work. For showing multiple images side by side rather than blended, the photo collage tool arranges them in a grid layout instead.
Practical compositing uses
Image overlay is also useful for straightforward tasks beyond creative effects. Placing a logo over a background at reduced opacity creates a simple watermark — for a dedicated workflow with position and size controls, try the watermark tool instead. Overlaying a texture onto a flat illustration adds surface depth. Combining two versions of an image - one sharp, one blurred - at different blend modes produces a selective focus effect. The ten available blend modes cover the most common compositing needs without requiring a full design application.
