Both photos are decoded straight into the browser and drawn side by side on an HTML canvas, not uploaded to a server or any third-party host. Because the layout, spacing, and background are all computed locally, you can change settings and re-export instantly.
How to use it
- Drop, click, or paste your first image into the left box, then your second into the right one (pasting fills them in order automatically).
- Choose "Fit" to keep each image's own aspect ratio, "Crop" to force both into matching squares, or "Square post" for one 1080 x 1080 image. Tick "Add labels" to caption each side.
- Adjust spacing and padding, and optionally turn on a gradient background with your own colors and direction.
- Preview the combined canvas and download it as a PNG.
Frequently asked questions
Are my two images uploaded anywhere to build the comparison?
No - both images are loaded and drawn onto an HTML canvas locally. Nothing is sent to a server.
How do I get both images in?
Drag-and-drop or click each of the two upload boxes, or paste with Ctrl+V - pasting fills the first image, then the second.
What's the difference between "Fit" and "Crop" mode?
Fit scales both images to the same height while keeping their original aspect ratios. Crop crops both to a square so they line up exactly. Square post makes the whole image 1080 x 1080, with each photo centre-cropped to a tall half.
Can I label the two images?
Yes - tick 'Add labels' to put a caption such as 'Before' and 'After' in the corner of each image, and choose top or bottom. For progress or renovation photos, the Before and After Photo Maker opens with labels already on.
Can I customize the background?
Yes - use a solid white background, or turn on a two-color gradient with a horizontal, vertical, or diagonal direction, plus adjustable spacing and padding.
What format is the exported image?
The combined comparison downloads as a PNG.
Why does the output look smaller than my original photos?
Each image is capped at 600 pixels on its matched dimension so the combined comparison stays a reasonable size for sharing. Your original files aren't touched, only what's drawn on the exported canvas.
