How to resize my featured image without appearing blurry?
I design my featured images using Canva. When I download it out, it is about 800kb and has a pixel size of 1350 x 650. The file format is png.
I will then proceed to resize it to 800 x 385, where I use a software Caesium, the size becomes 49kb. The problem is, the whole featured image (the wordings and the image) quality becomes blurry. And this happens be it png or jpg format.
Can anyone guide me on this, please? What am I doing wrong?
Thank you for your help.
