The primary cause of blurring images is the less than Photoshop-quality image downsampling algorithm currently used in Muse (that was compounded in early betas due to a bug in the JPEG compression library we were using at that time). Due to work we've done for Beta 7 to improve image encoding performance we now have the infrastructure in place to enable us to take a much better image resampler/resizer (after Beta 7), so this source of blurring will be addressed.
The other source of blurring is unique to opaque images containing line art or otherwise containing hard edges and large areas of solid color. When an image is opaque Muse will encode it as JPEG (if it's altered in Muse is a way that requires re-encoding). For line art this will introduce JPEG compression artifacts that can be noticeable depending on your eye and the specific image involved.
There are (at least) to ways to avoid these JPEG compression artifacts:
- Resize your image before placing and avoid applying any effects (rounded corners, drop shadow, etc.) or doing any cropping or resizing in Muse. If the image is unaltered your original JPEG, PNG or GIF will be passed through unaltered.*
- Put at least one pixel of transparency in your original image. (It could be a single 99% opaque pixel.) This will force Muse to encode as PNG. PNG compression is lossless and thus doesn't introduce any compression artifacts. However, an average PNG can be 5 times the size of a JPEG for the same image, so there is an impact to webpage download performance.
*For PSD files Muse has to encode the original PSD data into some web-friendly image format. If an image is resized in Photoshop and placed Muse won't resize/resample the image data, but it will encode it as JPEG or PNG depending on whether it contains transparency.
THIS IS RIDICULOUS...
why can't you simply select the image and ask it to output as jpg, gif or png!
get with the program guys and please intruduce this feature!
Is it really ridiculous? I think you didn't understand a word of the explanation above.
yeah was just venting the old frustrations...do understand though, and applied the single pixel transparency and the PSD files sharpen up immediately. THX for the pointer!
For me, the most simple way to prevent a picture from getting downsampled is to choose in one egde a rounded corner of 1 Pixel. This isn't visible, but causes Muse to use losless PNG-Format instead of JPG, because rounded corners introduce transparency, which JPG doesn't support.
Sounds good I will try this. Very good idea. THX!
sorry, but this is unbelievable for a program supposed to be a professional website-editor.
I have large line-art images in my site, and now have to include transparency to force Muse creating png and producing proper quality... should we laugh or cry?
In a current project I notice that Muse creates/exports thes SAME jpg for dektop AND phone version. that is the reason, in this case, for the lousy quality of this (lineart) images. They only have 380 px widht even in dektop version!
In a test file with only 1 page and 1 image for each desktop and mobile, Muse created TWO files. since there is nothing to influence from my side this must be a bug.
another way to get the image quality needed, we can exchange the images in the folder of the webspace. this is ridicolous too, shure, but the a way to get 100% what you want...
unfortunately in this case it does not work since the 380 px images are neccesary and ok for the phone version... ;-(
I understand your frustration. In many ways the controls in Muse are almost too simplistic. I know it's nice to have a simple and easy tool for website creation but the developers need to start giving the program some fire power!
Can someone walk me through how to put this transparent pixel into a PSD button. In photoshop, I've got my two layers for my rollover button and then I save it and the quality is awful in Muse. So is this transparent pixel just an extra layer? Because when I add it as an extra layer an save it, then import the PSD button in muse, this layer isn't detected by the photoshop import/state options under the PSD button interface, and the quality is still awful. Any guidance would be much appreciated.
Yes the blury PSD files in Muse is a very studip problem which requires the following action. Make sure your PSD file isn't flattened, this means the layer can't be called background in italics - this is the default setting, you will need to double click the layer and name it something else for this to change...and then ensure at least one pixel in your image is missing, this means you litterally have to delete the pixel revealing photoshop's background checker board pattern which indicates transparency (ensure this feature is turned on in your preferences, it is by default). It doesn't have to be one pixel it can be an entire row or even a column of pixels. The main thing to remember is that it must be "at least" one pixel in order for Muse to recognise the need to export as a PNG.
If you have multiple layers then I am pretty sure you just need to delete the same area in all of them thus revealing the checkers!
...any further questions please just ask!
Legend! Thanks for the advice! Works a treat.
What about HiDPi images for product like the Retina MacBook Pro? I want my webpage to look good on HiDPI screens too and not just a standard screen. Does anyone have any solutions?
I've also started noticing problems when using the retina screen. All the websafe fonts look fantastic but the supporting images set automatically to 72ppi and look terrible next to the beautiful crisp type. Adobe need to get onto this asap. Screen technology is miles ahead of the automatic preferences of the software.
encountered this software glitch and found a manual fix:
1) create an additional file copy of the image that appears fuzzy
2) open muse and left-click on the image that appears fuzzy
2) click the blue arrow to open the options menu for the lightbox
3) selected show lightbox parts while editing
4) right click on the enlarged lightbox image
5) click 'replace image' and select the additional file copy
image will now appear normal when the lightbox opens in the preview
will this help with my issue?
" I'm currently making a personal website/portfolio and its going to be fairly photo heavy. I'm currently having a few issues with getting high res photos imported. I have heard something about muse using different downsampling techniques to photoshop which can cause fuzzy images. currently I export photos as full res and screen optimised versions (PS down-sampled to 1080x1625) both of these and PSD files when imported to muse don't come out looking nearly as good as they should..? is there some other method i should use to import them or other file size/dimensions ? the poor quality issue is even worse when the image is used as a parallax scrolller? "
some of my photography uses multiple layers in PS but if its a single layer or just adjustment layers can I use the same removal of a single pixel ? thanks for your help
Ok, did this and they still look terrible. Is there another way to get the images sharp. Am beginning to wish I had never bothered with Muse............ ...... .
I am seriously shocked at this appalling bug. I have been a front end developer for over 10 years and image optimisation is one of the most important aspects of front end dev. Anyone who thinks that its ok to add one pixel with 99% alpha to render a PNG is an acceptable solution needs to go back to print design, you can't have hero photography as a png! I'm going to overwrite my images on the server manually. I just used Muse for this one project to see if it sped up workflow for the odd stand alone page, I'm not sure if I'll do it again.
It would be great if you could set the optimisation on the image.in a tool bar. Also a reset image dimension and container dimensions would be good.
This is STILL the only way to get around this bug... annoying.
How poor is this? For the first time i placed some logo trademarks on a colored background in Muse, previewd my site and was shocked how badly Muse rendered my files. I tried png, gif, psd - all of them are fuzzy and unsharp.
Really disappointing. Additionally i am using a very cheap web editor on my windows-based system. There i can right click any image file and decide whether to export my graphic as a png, a gif or a jpg.
i can even decide about transparency. Now come on Adobe - for more than 25 years you sell the world's no. 1 image editing software and are not able to make a proper image export out of Muse possible?????
Site Properties. Turn off Convert Opaque PNG to JPEG.
Could you please attach here one of those images – but attach the original image, no screenshot or something else.
mac, i found out something interesting: the graphic files i have used recently derived from my mac
and have now been used on a windows based system. on my mac they look okay (whereas muse
reduces sharpness during the output - no doubt about that). Now i have reconstructed the corresponding
files on windows (made new png's) and have a look at how it appears now (on the left the mac versions
of the graphics, far right the new windows version of the png-file):
i can live with this result, however the amount of sharpness reduction is quite annoying.
The images, you provided, perhaps are not useful to find out, what happens on your side.
If these images really are the originals (what I really doubt), the displayed quality has to be expected. Your images are
a) to small and definitely have to be scaled up within your Muse layout, what of course decreases quality.
b) blurry with a (white) color fringe already within the originals. You can’t expect, the image quality gets better when placing such bad pictures in Muse.
Here an image showing your screenshot on top and your original images at the bottom. The picture was composed directly in Photoshop without Muse being in the game and without any scaling:
In other words: If the images, you provided, really are the originals, no other qualitiy can be expected: The images are lousy and furthermore scaled up.
Now this looks really good, Mac
Clearly i know about svg and did a test just to analyze - the trademarks show up sharp and clean.
But i can't use svg-data because of restrictions associated by the use of a copyrighted logo.
Everybody could download those svgs and use them without loss of quality within illustrator
or any other vector based application. So this method/format won't fit the bill.
As mentioned and shown above - apparently the jaggy graphics did result from a converting and
saving on mac/windows. The files must have been "destructed" while being saved on
different systems. Your svg suggestion surely is useful for a part of the used logos on
my site so i will give this a try.
Thanks again for taking the time and suggesting some interesting alternatives
Again one important hint:
If you place an image without scaling it in Muse – that means: 100 % size – it will not even be touched by Muse. Such a picture will make its way from your disc through Muse to the browser without any modification. The output is identical to the input. You simply can verify this by comparing the original image with the image you take from the HTML/images-folder after "Export as HTML" or if you grab it from the browser view.
That means: Verify within Muse, what pixel dimensions an image has to have and use Photoshop (or something else) to meet these dimensions exactly.
You can see here, what is possible:
The "new" Logo next to the arrow has exactly the same dimensions as those you posted above – and it was placed as a PNG!. You see: No bluriness at all …
Over the past three years since this original post has there been an easier way to solve the problem of blurry and pixelated images. I have tried everything mentioned above and my photoshop images that are imported into muse look like hell. One image in particular was originally taken last month on a Canon 7d mkii imported in to PS as a JPEG, I unlocked the layer and deleted the background around my subject, I saved as: PNG which looked great until it was in Muse. I tried resizing the image in PS and then place it in the muse website and still looks bad. I also read the post about making one pixel transparent, which I would think by deleting the background on the image, it would have made 80% of the image transparent, right? I give up and would like to see if someone has a solution to the problem! this has been driving me crazy for years, but I have just lived with it. Its a very unprofessional look to a website when the images are blurry.
I think, you didn’t read exactly.
For you one more time:
If you (1) switch off "Convert opaque PNG to JPG and (2) place your images in 100 %, Muse won’t even touch these pictures!
They will be passed over without any modification from your hard disk to your website.
Did you compare the original asset with the outputted picture in the images folder of your site?
If you respect (1) and (2) there can’t be any difference!
Mac, Im a little retarded and don't always comprehend what i read.. I appreciate your reply and will give it a go. Thank You
Given this answer was posted 6 months ago, when is the issue likely to be "addressed"?!
You did read the postings, didn't you?
Question marks don't work on a sliding scale. I totally missed the 2012...I'm a little stunned that it's actually been this long and a simple in-software resolution still isn't in place - weird. I'm still getting the same issue, trying ALL the fixes as suggested within CC and getting terrible results.

I don't see it.
I'm not sure it could be much clearer. I've resolved the issue.
