Image Compare Slider
Drop two images. Drag the divider to reveal the difference. Export the result as a single PNG. Everything stays on your device — no upload.
Everything runs in your browser. Your images are never uploaded.
FAQ
Are my images uploaded anywhere?▼
No. Both images stay in your browser tab — they're never sent to Pyrelo or any other server. Close the tab and they're gone.
Can the two images be different sizes?▼
Yes. The 'after' image is scaled to match the dimensions of the 'before' image so the slider lines up. For the best result, use images that are the same aspect ratio.
Can I export the compared view?▼
Yes — click Download composite. We bake the slider position into a single PNG at the source resolution. Perfect for before/after social posts or design reviews.
Does it work on phones?▼
Yes. The slider responds to touch as well as mouse.
Why is the slider vertical and not horizontal?▼
Vertical (left/right reveal) is the standard for landscape photos. Use the orientation toggle to switch to a horizontal slider for portrait photos or top/bottom comparisons.
