Hello,
I have been working on a design.
For 3 months now i have tried all possible ways to export the design as a pic.
It looks ok on the laptop after exporting but when uploaded to facebook, it looks very blury.
I have tried several pixel sizes,resolutions and bit depth but i still face the same problem.
I need help urgently.
Thank you.
perhaps Facebook reduces the quality of downloaded images
First off resolution (dpi) has NO effect on web images, that value is irrelevant so forget the dpi thing and just deal with pixel h x w. When the sizing is correct export for the web and optimize the image. Without seeing your image it is not possible to figure out what you are doing.
Yes, facebook automatically downsamples pics. If it's a pic for an ad i.e. a logo it's best to find out what file limitations are with facebook then match your image to those specs. Often times just grabbing a corner and scaling it distorts the image in many ways.
If you are playing with the dpi settings that will produce blurry. If you are trying to make a small image larger (upsample) that will also make it blurry. Make it the exact size facebook requires and it will look super. if you are making it smaller (downsampling) make sure you sharpen it a bit. Coming down also blurs things a bit. Must be exact size going up.
If you are taking he same single image and doing all of these things to it that will trash it.
Bob, I disagree. A large res image will slow your website down. That's one of the reasons facebook downsamples them all. If people visit a site and it takes a long time to load it's usually a bunch of images that aren't sized properly. Images for web use shouldn't be more than 96dpi. It's quite possible for anyone with cd/photopaint or illustrator/photoshop to make an image 600dpi AND 18" x 24"
