Was using Photoshop's Quick Export to PNG with a 250x59px grayscale image. Chrome vs Safari vs Firefox comparison (ok nevermind about Firefox it's whack):
Tried searching the chromium groups for anything similar but didn't find anything specifically like this. Anyone know what's going on? Only seems to happen on smaller sized images, this same image not scaled down from 2000+ px does not show the same inner glow-y stuff.

On Windows, and to a certain degree also on Mac OS, with different browsers (Firefox, Chrome, Safari), our menu bar has rather pixelated/blurry font-rendering. This is on an ASP.NET Core 2.1 site that uses Bootstrap 4.1.3 but it's easy enough to reproduce with just simple HTML: https://jsfiddle.net/2tgc9r84/
<html>
<body style="background-color:#e72c87;">
<p style="font-size:20pt;">
This is some text that looks terrible.
</p>
</body>
</html>
Interestingly, the same font renders just fine in other areas of the site. I have noticed this on a 4K monitor that has 150% scaling activated but the issue also shows up with 100%. I have also tried this with different fonts, so apparently it's not an issue with the font, either.
Originally I thought this was an issue with transparency or transformations but finally, I tried simply changing the background color - and it turns out this blurriness is very obvious with red and dark blue (and of course, combinations of those, like magenta), and pretty much invisible with most other colors. Also, by changing the main background color, I can reproduce the issue for the other areas.
You can directly have a look at the site where this occurs here: https://beat-the-rhythm-vr.com/Home/Social (the navigation with the blurry text shows up after accepting the cookies).
Here's an image that shows the effect with different backgrounds, and also rendered on Mac OS (the Mac OS screenshots appear smaller in the image):
As far as I can tell, this does not happen at all on iOS. On the Mac, I don't quite see the issue on the screen but it does become obvious when making a screenshot. This could, however, also be an artifact due to scaling on the screenshot.
This is what it looks like on iOS (I get the same blurriness on Windows when making the Window small enough to get the same layout as on mobile, so that's also not the issue causing this / fixing this):
The obvious question: Is there any way to fix this, and if so, how?
EDIT: This is in addition to the comment on Porter's answer (I can't add screenshots in comments, so I'm posting this here):
EDIT 2: While this article is about a slightly different issue, my guess is that what I'm seeing is really just a limitation of ClearType that is related to what the article outlines: Color-aware ClearType requires access to fixed background pixels, which is a problem if you don't know what the background pixels are, or if they aren't fixed
ClearType apparently doesn't work when the background color isn't known, and from what I'm seeing, it seems to be designed primarily for black text on white backgrounds, also works well with light colors on dark backgrounds but not really so much for red/blue/magenta backgrounds (and any font-color).
I am unable to reproduce this on a 1080p or 4K display, with either mobile or web view on Firefox and Chrome. Fonts do tend to blend with the background color, so not every pixel of the font is going to be the same color; It'll blend on the edges. The smaller the font, the less pixels it has to work with for blending. If you use a larger font, does the same problem occur?
If you look at this page, you will see that the right two images are sideways:

But when you click on them, they appear correctly in full screen view, vertically. I can't see anything wrong in my HTML img code that could cause this.
Can anyone tell me why this is happening? These photos were taken with an iPhone 5 by the way.
This is a particular problem with how the iPhone exports images. Seem this link for a similar situation.
Computers/browsers and iPhone software interpret the camera metadata (details about image, including portrait/landscape) differently thus causing the difference in rendering.
I was able to download the far right image in Pixelmator/Photoshop and save it as a jpg again, making sure it was portrait. This made it so the browser properly rendered the image and did not rotate it 90 degrees.
Were these pictures taken sideways, by any chance? Have you tried editing and "exporting for web" from Photoshop, for example?
Maybe the problem is on the image EXIF (as in you only see the image correctly because the browser reads the EXIF info and rotate it on screen). Exporting it will most likely remove that info from the image file and it might make it correct.
I spent an hour with this that I'll never get back. :)
The Problem
I took the picture on my Samsung GALAXY Tab PRO 8.4. It rendered SIDEWAYS in an Android Emulator as well as in FireFox 42.0.
The Fix
I edited the picture in IrfanView.
I went to Properties_Settings -> JPG_PCD_GIF ->
UNCHECK "Auto-rotate Image according to EXIF info (if available)"
It now renders OK in FireFox. I haven't checked the emulator yet.
When designing my site i noticed that under dark backgrounds all of the images I used as sprites turn out like this:
I have tried multiple versions on PNGs and GIFs. IT works fine under firefox.
However, if i do not use sprites the image displays as:
This is the same exact image just without any positioning tags.
Can anyone help?
I fixed it. The issue was my cache needed to be cleared!
I am optimizing my site for these higher resolution monitors (especially the new iPad). I have the site formatted the way I want, and I was just increasing the resolution of each image but still constraining it to the DIVs that I currently have. For example, I have an image with a resolution of 483x246 and I have it fitting a DIV with a set size of 188x96.
The images look great on Chrome, Firefox, and most importantly on the new iPad. Even zoomed in it's nice and crisp (as opposed to my old 188x96 image that looked blurry and pixelated when zoomed in)
The problem comes in when I open the page in IE. It displays the image at the correct size but it's jagged. See link to comparison below. I know it's an issue with the way IE resizes and renders pictures on the fly.
My question would be, is there a way to make IE display the picture nicely? If not, is there a way I can put in the code so that if it detects IE, it displays my old low res image? I've looked everywhere but haven't found anything that relates to my specific problem. I know this is a small example but my bigger images do the same thing and are more noticeable. I hope you all can help. Thanks. :)
Comparison:
Have you tried putting this in your CSS?
img { -ms-interpolation-mode: bicubic; }
There's also this https://github.com/adamdbradley/foresight.js which looks very interesting
Make sure IE9 isn't in compatibility mode or IE7/8 mode...
The reason this happends if because the bitmapdata is actually rendered completely different in the IE browser, the thing IE does is it "cuts" away pixels over a set ratio so like every 5 pixels it yanks a pixel and therefor makes it look like it misses certain gradient properties.
not much you can do about this except for keeping the aspect ratio set but I guess you would've known that by yourself already
I have a Joomla website and I observe a problem with some images.
In Chrome images look really good and sharp but in Firefox and IE the images are not that sharp and the colors are a bit strange.
Take a look at the photos below. The difference is more obvious on the Standings were the emblems of the teams are really small.
Any suggestions??

You're telling the browser to scale the image from 150 pixels to 60 pixels.
Most browsers aren't good at that.
You should create images that are exactly the right size using an image editor.
This will give you complete control over how the image is scaled (image editors do a much better job than Firefox), and make the files smaller too.
