Before & After Slider
Compare two images side by side with an interactive drag slider. Upload before and after images, drag the divider, and download the combined view as PNG. Free, no sign-up.
Frequently Asked Questions
What image formats can I upload?▼
PNG, JPG, GIF, and WebP images are supported for both the before and after slots.
How do I drag the slider?▼
Click and drag the vertical divider line left or right to reveal more of the before or after image. On touch devices, use your finger to drag.
What does the Download button export?▼
It exports a PNG that captures the current split view — showing both images at the current divider position. The left side shows the before image and the right side shows the after image.
Is there a size limit on the images?▼
There is no enforced size limit, but very large images may slow down your browser since all processing happens client-side. Images are automatically scaled to fit the display area.
