Common questions
What aspect ratio should I use for Instagram?
1:1 for square posts, 4:5 for portrait posts, which take up the most space in the feed, and 9:16 for stories and reels.
What is the aspect ratio of a YouTube thumbnail or a website banner?
YouTube thumbnails and most video players use 16:9. Website banners vary; 21:9 or 3:1 are common for wide headers.
Will cropping reduce the quality?
Cropping only cuts off edges; the remaining pixels are not resized. Saving as JPG or WebP compresses again, so choose a high quality or PNG.
Are my images uploaded?
No. They are cropped in your browser and never sent to our server or anyone else.
