Blend Two Images Together
Upload a base image and an overlay, then choose a blend mode to combine them. Canvas globalCompositeOperation handles the math — from simple darkening (multiply) to creative effects (difference, exclusion).
Frequently Asked Questions
What blend modes are available?
Normal, multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, and exclusion — 12 modes total.
Do both images need to be the same size?
No — the overlay image is scaled to match the base image dimensions. The base image defines the output size.
What is the opacity slider for?
Opacity controls how visible the overlay is. At 100%, only the blend mode effect shows. At 50%, you see a mix of the original and blended result.
