When I'm trying to view pixel art up close, chrome starts blurring the image. I want to make it so that even when the image is zoomed in, I can still see the pixels in crisp detail, not a blurred one.

1At the moment I don't think you can disable the smoothing algorithm that chrome uses that smooths out the edges of the images when you zoom in them. Unless there's an extension that does so or someone knows something that I don't know as of yet.– DuckDuckGooseJan 9, 2013 at 7:50

By zooming do you mean ctrl/cmd and +?– booyaaJan 9, 2013 at 16:49

@booyas, yes, that's what I mean.– PropellerJan 10, 2013 at 14:40

1Things have improved, now this is a possible duplicate of stackoverflow.com/questions/7615009/… . In particular, see namuol's answer and jsfiddle at jsfiddle.net/namuol/VAXrL/1459 which demonstrates what I think you are wanting. TL;DR for chrome: "image-rendering: pixelated;" on img and canvas elements.– Don HatchJan 24, 2016 at 23:44

Not your question, but is it possible to store the images in higher quality at least, and then would the zoom use the extra detail?– XonatronMay 30, 2019 at 18:05

As per the comments:
it is now possible in Firefox: image-rendering: optimizeSpeed; – Arnaud

This isn't possible directly from the browser.
The smoothing is applied via an algorithm and most modern browsers do similar and in IE, Firefox and Chrome there is no way to turn this off.

You do have other options, here are the 2 main points from the link above, both are Chrome addons.
You could apply the CSS code below in the browser, which will turn it off!
img {
image-rendering: optimizeSpeed; /* */
image-rendering: -moz-crisp-edges; /* Firefox */
image-rendering: -o-crisp-edges; /* Opera */
image-rendering: -webkit-optimize-contrast; /* Chrome (and Safari) */
image-rendering: pixelated; /* Chrome as of 2019 */
image-rendering: optimize-contrast; /* CSS3 Proposed */
-ms-interpolation-mode: nearest-neighbor; /* IE8+ */
}

4Have you just said it's not possible and then pasted a working code to actually do it? Feb 24, 2016 at 10:36

I made this bookmarklet to disable smoothing. I keep the link in my bookmark bar and tap it when I want to disable the antialiasing on a page, usually for pixel art or classic gaming:
javascript:(function pixelate() {
const sheet = document.createElement('style');
sheet.innerHTML = 'img { image-rendering: pixelated; }';
document.head.appendChild(sheet);
for(let i = 0; i < frames.length; ++i) {
frames[i].document.head.appendChild(sheet);
}
})()
The reason a bookmarklet was appealing is that I don't like giving extensions the "read and change all your data on the websites you visit" permission.
I've noticed some issues with Chrome and Firefox when using GPU rendering with images. E.g.:
img {
-webkit-transform-style: preserve-3d;
transform-style: preserve-3d;
}
If you have any CSS statements with the following, try removing them and see if your image quality increases.
