Photoshop: Low quality JPEG files and strangely small Photoshop display

Hello,

Here's a problem I'm dealing with for a week now :

First, the image size on Photoshop is not the same as in other application. Photoshop displays them twice smaller than in reality.

This is annoying because I can't work on my stuff and see it how it's supposed to be seen. It somehow can be fixed by zooming 200%. 

Second, and worse : when I save my images as JPEG (even at 12), the quality is really poor. It's very annoying for webdesign work where I need high quality images for clients.

Can someone help me fix this ?

Do you happen to be working on a 27-inch Retina 5k iMac?

I do not have a problem displaying my full image size in Photoshop. I'm not an expert, but it seems to me that the problem you are having is your problem, not Photoshop's. In order to get help with your problem, you need to provide detailed information about your system, what you are trying to do and what is going wrong.

Photoshop displays images at 100% pixel per screen pixel. Many browsers and other applications, scale up images using interpolation. You should design your work at twice the resolution to accommodate HDPI monitors. https://www.leemunroe.com/designing-for-high-resolution-retina-displays/

I work an a 13,3 inch MacBook Pro Rétina with Mojave.

My problem is simple : I remember a time when Photoshop displayed the images the size they actually were. Beside, when I saved them as JPEG, they would not only be saved in the same size I was working on in Photoshop, they would also have a very nice quality.

That was a much happier time. I wish I could go back then. Now, my JPEG appear twice as big in Image Viewer and in my browser and their quality is pretty poor.

I've spend nearly all day chating with an Adobe supervisor who could not find the solution to my problem. They basically answered to me that they did a lot of changing and that's one of them.

So I ask myself : Why, dear God, why ? Everything worked so well.

I'm basically stucked. I have to have high quality images since I'm a graphic designer and I just can't send to client low quality images. But with that messing up, I can't work. Which means I can't earn money, which means I can't eat.

Sorry but I'm very desperate right now.

Nothing has changed about how we save JPEG files from Photoshop.  Are you using File > Save As or File > Export > Save for Web (Legacy)...?

If using Save As, what Image Options are you choosing?    As I'm sure you're aware, it's the Quality Slider that affects the resulting image quality.  I try to keep this at 8 or higher, but never lower than 6.

If using Save for Web, what options are you setting there?  I try to keep this at 80, but never lower than 60.

Either approach should get you pretty good looking JPEG files when viewed at 100% in any application that displays JPEGs.

I've tried every possible setting. No matter what, I still end up with huge images with low quality. I've tried several versions of Photoshop, I've even changed my MacOS to El Capitan again. No result.

I tried everything, I asked everyone. Maybe I should just use another software for my webdesign stuff. Which is quite painful knowing that I've spent 10 years trying to learn Photoshop...

Here's a logo I saved as JPEG with best resolution possible. We can see that it's kinda blurry and has pixelisation on it. This is not just because I uploaded it here on the forum. It looks like that on my Image Viewer too.

I'm probably stating the obvious here, but something is causing the 490x261 image to be displayed at 200% (or 2x).

I copied your image to Photoshop and it correctly posted at 100%, looking sharp as expected; however, a screenshot shows the 490x261 displayed at 980x522, looking blurry. 

  

What method are you using to have the JPEG?  I used File > Save As.

Okay... here's where the display of web graphics gives me a small headache.

If I right-click 1st "Le coqulicot" image (the one that you posted, Yassine) the graphic directly and copy it before clicking on it to open it in a new window, the pasted result is sharp at 490x261.

If I click the 1st "Le coqulicot" image, it opens in a new window at 1000x552 and looks great.  

The JPEG only appears to be going soft when not displayed at 100%, either larger or smaller.  I think the issue is outside of Photoshop and the way to resolve it is to make sure that you always have a version that matches how it's going to be displayed.
