Frequently asked questions
Which aspect ratio should I use for a thumbnail?
16:9 is the standard widescreen ratio used by YouTube thumbnails, video covers, and most presentation slides.
What aspect ratio is best for social media posts?
1:1 square works well across most feeds, while 4:5 and 4:3 are common for portrait-leaning posts. Choose the ratio that matches the platform you are uploading to.
Can I crop to a ratio that is not listed?
Yes. Switch to the custom ratio option and type any width-to-height values, such as 21:9 for an ultra-wide banner.
Does cropping reduce the resolution of my photo?
Cropping removes pixels outside the selected area, so the output is smaller than the original unless you zoom out. You can set the exact output width and height before downloading.
