Best export config?

Hello guys,
I have made my design in PS, but i have a problem with the export configuration.
If i export the file with best quality the size is to large, but if i export for gaining small size, the quality isn't good enough.
Any suggestion for the best export config with "not too bad" quality and small size ?
Thanks

Really depends of the type of file you want.
Are you exporting a JPG? a TIFF? a PDF?

Other thing might be the PPI. Did you make your design at 300 PPI?
And is the export you want a final version, are something you want to show to someone else as an example?
Decreasing your file to 72 PPI also greatly decreases the file size, while it still looks good most of the time (for example; on a screen)

We need a little bit more info to give you a correct solution

did you set the resolution to be? If you left at 72 dpi (counts per inch), the logic is that the pixel is small, and the file is not as difficult as losing quality.

300dpi is a better solution if you want high-definition image processing. Usually for them ranges from 300-600dpi maximum.

The problem can be solved in two ways. If you go into Photoshop to Image-Image Size-that you can adjust the image resolution in dpi.

Another solution is to change that image on a document of 300 dpi, and its izrezanjem over the crop tool. Be sure to save the image as a JPEG, but can be preserved and the Save for Web & Devices, where exactly are you going to get better image quality and clearer picture.

On the third point of view, check out the Adobe Photoshop Lightroom, because it works perfectly well with manipulating the image processing, but it is alone Photoshop able to do. There could well adjust image exposure, image quality, the results are seen after her treatment, which is very good, because there is no pixel problem.

Here is the link of Photoshop Lightroom

Adobe - Lightroom : For Windows : Adobe Photoshop Lightroom 3.3

But the last versions of Photoshop Lightroom is the best for results with images

PortableAppZ: Adobe Photoshop Lightroom 5.3 Multilingual 32 & 64 bit
