: How to make typography hi-res for web? Suppose I'm going to make a typography poster (or whatever) that's going to be posted for advertisement in, let's say, Facebook, how high should the resolution

@Smith574

Many folks used to resort to automatically answering 72dpi, as that was the old school monitor resolution. Now monitor resolutions are much higher. If you view a jpeg in your web browser that is too big to be seen at 100%, most of them automatically scale them down to fit the whole image. So there is no hard fast answer on the resolution question without knowing more about the end use. I will tell you that there is no reason to go higher than 150dpi.

Jpeg compression is not ideal for continuous tones and solids. It's good for photos. If you are doing text and line art, PNG is a good format. GIF is outdated, PNG has superseded it in pretty much all aspects outside of animation.

I believe Facebook only allows JPG images and, on top of that, Facebook re-compresses JPG images.

The issue you are having is likely less to do with the particular resolution of the image you are creating and more to do with JPG compression--which typically makes any text blurry.

I may be wrong about the JPG-only part, though. If I am, try uploading your images as GIF or PNG files. The compression that GIF and PNG uses will likely produce a sharper image for type than JPG does.

If you are doing this ONLY for facebook, determine the max width or height available to you and then make your image exactly that dimension.

If you are doing this for yourself, then do it however you like and then export a reduced size version with the right pixel dimensions for facebook, then upload that copy to facebook.

The advantage of this is that you are able to tweak it, sharpen it etc before you upload it. Export to PNG-24 if possible (if facebook supports that of course), since this will preserve colors and the text will look as crisp (virtually) as in the original. Jpeg tends to blur and smear areas of solid color because of the nature of the compression algorithm.

Finally, once you upload the image to facebook, save the uploaded image back to your computer and compare it to the one you uploaded. Look at the file size, the file type, etc. This might will help you figure out how it changes during uplaod and then decide on how to work with the problem.

Try to save poster in png.
May be you try to upload too big image, that downsampled on server automatically.
