Lorel Posted December 12, 2019 Posted December 12, 2019 I often take a youtube video and resize it as a thumbnail to post on a website however it always comes out fuzzy. Here are the steps I'm taking: 1. copy image in browser 2. Choose new/from clipboard 3. choose document/resize doc Settings (change to 72dpi, size 125 x 71 px, leave resample checked, leave bilinear checked.) 4. view/zoom/actual size 5. export (it shows quality is down to 45% -- I usually use higher quality but even if I improve quality from here it doesn't improve image). (I've also tried bicubic). Can anyone tell me what else I can do to improve quality? Quote
Lorel Posted December 13, 2019 Author Posted December 13, 2019 Sorry I can't do as you suggested because there are up to 30 of these thumbnails per page. That would cause a massive download speed and harm ranking. I guess I'll have to find another program that can resize images. Quote
walt.farrell Posted December 13, 2019 Posted December 13, 2019 You could try one of the other resampling options. What are the original pixel dimensions?

If you are looking for something that will resize large images to just 125 x 71 px without a dramatic loss of detail (which I think is what you are interpreting as fuzziness), you are not going to find it. That is because a pixel is the smallest possible unit of detail of a raster image. So all you have is a rectangular grid of 71 x 123 pixels, each pixel of which must be filled completely with only one color. There is no way around this. You must increase the size (number of pixels) in the image if you want greater detail/less fuzziness.

For such a massive downscaling it is useful to sharpen the image afterwards. Example from 1500 px > 125 px: not sharpened / sharpened: (enlarge your browser zoom to make the difference more obvious.) < bilinear < bicubic < lanczos The resampling algorithm doesn't really matter here.

Lorel Posted January 4, 2020 Author Posted January 4, 2020 Thanks everyone. Sorry I'm so slow. I had to upgrade my computer. I'll try what you suggested as they sound like very good suggestions. Quote
