Online image merge tool that combines two images into one. Supports horizontal and vertical merging with adjustable spacing and alignment. Client-side Canvas processing, no upload needed.
Frequently Asked Questions (FAQ)
What merge modes are supported?
3 modes: ① Horizontal: two images side by side; ② Vertical: two images stacked; ③ Grid: 2×2 grid layout (requires 4 images). Adjust order, spacing, and alignment before merging.
How is the output size calculated?
Horizontal merge: total width = imageA width + spacing + imageB width, total height = taller of the two. Vertical merge: similar. Choose 'top', 'center', or 'bottom' alignment for different height/width images. Images are never stretched or cropped.
What image formats are supported for input/output?
Input: PNG, JPG/JPEG, WebP, GIF. Output: PNG (lossless, recommended) or JPEG (lossy, adjustable quality). Use PNG for text screenshots or images needing transparency.
Is image merging done locally or on a server?
Completely local browser processing using HTML5 Canvas API. Your images are never uploaded to any server. Works even offline.
