⚙️ How It Works
1
Upload two images
Drop your 'Before' image on the left slot and 'After' image on the right. Both render at the same display width for accurate comparison.
2
Drag the comparison slider
A purple slider handle divides the canvas. Drag left to see more of the right (After) image, drag right for more of the left (Before). Labels identify each side.
3
Download the current view
Download a snapshot showing exactly the current slider position — useful for showing a specific comparison point in a report or presentation.
❓ Frequently Asked Questions
How do I create a before and after image comparison?
▼
Upload your 'before' image in the left slot and 'after' image in the right slot. The slider divides them — drag it to reveal more of either side. Customize the labels to 'Original' / 'Edited' or any text you prefer. Download a snapshot at any position.
What is a before-after image slider used for?
▼
Common uses: showing photo editing results (original vs retouched), displaying design changes (old vs new website screenshot), demonstrating product comparisons, showing seasonal changes in landscape photography, and illustrating the effect of filters or treatments.
Do both images need to be the same size?
▼
No — the tool works with images of different sizes. Each image is scaled to fill the canvas width independently. For the most accurate visual comparison, use images of the same dimensions and content framing.
Can I embed the comparison slider on my website?
▼
This tool creates a downloadable snapshot. For an embeddable interactive slider on your website, you would need to implement it in code using libraries like img-comparison-slider or TwentyTwenty jQuery plugin.
What's the best way to show photo editing before and after?
▼
Export a copy of the original before editing (the 'before'), then upload both the original and your edited version here. Position the slider at 50% for a balanced initial view, then download that snapshot. This is particularly effective for showing retouching, color grading, or background removal results.
