Your unique share URL appears instantly. Copy it with one click and send it anywhere. Anyone who opens it sees the live interactive comparison — no login, no app, no friction.

⇄
Interactive Split-Screen Viewer

The generated viewer uses a real draggable divider — not a static GIF or screenshot. The handle can be dragged to any position, letting viewers examine specific areas of both images at full resolution.

🔗
Instant Shareable URL

Every comparison gets a unique link at imglab.net/slider/. No expiry, no paywall, no account needed for viewers. Share in Discord, Reddit, Twitter, or embed in a blog post — it just works. A Share button in the viewer lets anyone re-share it instantly.

🔄
Auto WebP Conversion

PNG and JPG files are automatically converted to WebP before upload, shrinking file size without visible quality loss. A quality slider lets you tune the compression level from 1–100.

🏷️
Custom Labels & Name

Name each image (e.g. “Before” / “After” or “Original” / “AI Upscale”) and give the whole comparison a title. The name becomes part of the shareable URL and the viewer heading.

🔍
Zoom & Fullscreen

Scroll to zoom, type an exact percentage, or pick a preset (Fit / 50 / 100 / 200). Inspect fine detail — texture, sharpening artifacts, noise — at full pixel resolution. Fullscreen mode fills any display.

❤️
Hearts — Up to 5 per Person

Viewers can tap the ❤ button up to 5 times on any comparison to express how impressed they are. The live total updates in real time. Counts are stored per-browser, so returning visitors pick up where they left off — no login needed.

❤ ❤ ❤ ♡ ♡ Up to 5 · live count · no login
⇄
Swap Images with X

Press X on your keyboard to instantly swap the left and right images. Upload order no longer matters — you can always flip them in the viewer without re-uploading anything.

🛡️
Safe Content Filtering

Uploaded images are checked for inappropriate content before processing. The tool is safe for public sharing and won’t host content that violates community guidelines.

❤️ More Than a Like Button

Unlike a simple one-click thumbs-up, IMGLAB Slider lets every visitor give up to 5 hearts to a single comparison. Each tap adds one heart — so if you’re truly blown away by a restoration or transformation, you can keep clicking to give it the recognition it deserves. The live count updates immediately for everyone viewing the slider. Once you’ve given all 5, your contribution is locked in for that comparison.

❤ ❤ ❤ ♡ ♡
❤ 3 / 5 given · 2 remaining · updates live
💡
A single click like doesn’t convey intensity. When someone gives all 5 hearts to a before/after AI restoration, that tells a much richer story than a binary thumbs-up — and makes heart totals a genuine signal of how impressive a comparison really is.
✦ What People Use It For
🤖
AI Upscaling Tests

Compare your original image to the AI-upscaled result side by side. Let others drag the slider to judge the difference themselves — much more convincing than two static screenshots.

🖼️
Photo Retouching

Show clients or followers the before/after of a retouch job. The interactive format beats a static before/after grid — viewers can focus on exactly the area they care about.

🎨
Design Reviews

Compare two design iterations, color grades, or filter presets. Share the link in Slack or a design review tool and get precise feedback on the differences.

📷
RAW vs Edited

Show the full impact of your Lightroom or Photoshop edit. A draggable slider communicates the transformation instantly in a way no static export can match.

🗺️
Map / Satellite Changes

Compare satellite or map imagery across time periods. Urban development, deforestation, disaster impact — the slider format makes temporal changes immediately legible.

🔬
Algorithm Benchmarks

Testing two image processing algorithms? Share the output as a slider and let collaborators evaluate the visual difference precisely, without needing to run the code themselves.
