Good to know
Every platform wants a different shape: square or 4:5 for Instagram posts, tall 9:16 for stories, wide 16:9 for YouTube and very wide banners for LinkedIn and X. Uploading one photo everywhere means the platform crops it for you, often cutting off heads or text.
Here you choose. Crop to fill keeps the frame full and trims the edges, centred on the spot you click. Fit keeps the whole photo and fills the gaps with a blurred copy of it or a plain colour, which works well for wide photos in a tall story.
Each size is saved at the exact pixel dimensions the platform recommends, so it stays sharp after upload. Platforms change their layouts from time to time, so check how the result looks in the app's own preview before you post.
Frequently asked questions
What size is an Instagram post?
1080 × 1080 pixels for a square post, or 1080 × 1350 for a 4:5 portrait post, which takes up more of the feed.
What size is an Instagram story?
1080 × 1920 pixels, a tall 9:16 frame. The same size suits Reels covers.
What size is a YouTube thumbnail?
1280 × 720 pixels, a 16:9 shape. Keep the file under 2 MB.
What size is a YouTube banner?
2560 × 1440 pixels, but phones and computers only show the middle 1546 × 423, so keep text and logos there.
What size is a LinkedIn banner?
1584 × 396 pixels for a personal profile. Your profile photo covers part of the lower left.
Can I keep the whole photo without cropping?
Yes. Choose Fit, and the gaps are filled with a blurred copy of your photo or a colour you pick.
Is it free?
Yes. Every size for one image is free.
Is my photo uploaded?
