imgsli is down. Here’s the free imgsli alternative to use

So you went looking for imgsli and landed here instead. Heads up before you keep hunting: imgsli.com is parked on an under construction page right now, so the little slider a lot of us leaned on for years just won’t load. Might come back, might not. Nobody really seems to know. But here’s the part that actually mattered, two images stacked in the exact same spot with a divider you drag between them. That’s the whole reason imgi exists, and you do not need an account to try it.

imgi is an imgsli alternative

imgi is a small, fast tool for comparing two images. Drop in a before and an after, drag the divider, and the change jumps out, a sharper texture, a color that shifted a hair, whatever moved. Two screenshots sitting next to each other never quite show that. A slider does.

And the fine detail is usually the whole point of a before and after, so imgi won’t quietly crush it. By default your files go up and come back at full quality, pixel for pixel, zero compression. Want smaller, faster-loading files? Turn on Compress. Out of the box, though, what you compare is the real image and not a squished copy, which is what matters when you’re judging an upscale or a retouch.

You get a short link you can hand to anyone, and it keeps working. That part matters here of all places: imgi’s links are permanent, so a comparison you post today is still live next year. And if the images should never leave your machine, offline mode runs the whole thing in your browser with nothing uploaded. We also wrote up the switch in more detail over on our detailed guide to switching. Coming from imgdiff.net instead? See the imgdiff alternative page.

imgi was built with permanence in mind, it is free and will stay free forever. If you just watched years of imgsli links go dark, that promise is the whole point. Hosting is paid for by ads on shared pages, not by holding your images hostage, and it is a stated commitment, not a hope.

What imgi offers

• Drag to compare. Horizontally or vertically, with a mouse, a finger, or the arrow keys. It’s fine on a phone.
• Permanent links. Every comparison gets a short URL. Paste it in a forum or hand it to a client, it keeps working.
• Embed it straight into your own site, blog, or a Nexus mod page.
• Up to ten images in one comparison, not just two, and you flip between which pair shows.
• Offline mode. Compare two files right in your browser, nothing uploaded and nothing recompressed, for when they shouldn’t leave your machine.
• Full quality by default. Nothing gets crushed on the way in. Flip on Compress only if you want smaller, faster files.
• Private links and no ads with Pro.

How to compare two images with imgi

1. Open the imgi home page and drop in your before and after images.
2. Drag the slider to compare, and label each side so viewers know which is which.
3. Click Publish for a permanent link, or Offline to compare without uploading.
4. Copy the embed snippet if you want the slider on your own site.

Ten seconds, if your two images are ready to go.

Moving from imgsli to imgi

The muscle memory carries over almost one to one. Two images, a divider you drag, a short link at the end. Here is the practical version of switching:

• Single comparisons work exactly how you remember: drop two images on the home page, drag, publish, share the short link. Labels go on each side so viewers know which is the before.
• Album users: imgi albums hold up to 30 comparisons behind one link, with a thumbnail strip to flip between them. Click “Add another comparison” in the tool to build one. You can add, remove, reorder, and rename comparisons later, and even swap out a single image, all without the shared link ever changing. Handy when a mod update replaces half your screenshots.
• Old links in your forum posts: those point at imgsli’s servers, so nothing can bring them back from our side. If the source images still exist on your machine, recreating a comparison takes seconds, then it’s one edit to the post. For anything you no longer have, try your old link on the Wayback Machine, some comparisons were snapshotted.
• Embeds: every imgi comparison has an iframe snippet under the Embed button. Paste it into a blog, portfolio, or mod page and viewers get the working slider inline.
• One difference worth knowing: imgi serves your files at full quality by default, byte for byte what you uploaded. Nothing is silently recompressed, which matters when the entire point is judging fine detail.

Who actually uses a before and after slider

If you searched for imgsli, you probably already know why you want one. Retouchers use it to show a client the edit against the untouched shot, because a slider makes the work obvious in a way a flat before/after JPEG never does. Game modders lean on it hard, which is exactly why Nexus, Reddit, and Discord filled up with imgsli links over the years, a mod next to vanilla with one drag. And lately it is the AI upscaling folks: load your upscale against the source and you can tell in about two seconds whether it actually added detail or just softened everything. Same tool, same idea, whether you are shipping a retouch, a render, or a texture pack.
