Social Media Image Sizes
Don't want anything cut off? Choose a padding option. Want the frame filled? Choose “Crop to fill”.
Get the size right before you post
YouTube thumbnails and Instagram posts are shown at fixed ratios. Upload a photo with a different shape and the important part gets cut off, or the app crops it for you. This tool makes the exact pixel size for each platform — either cropping to the part you choose or padding so the whole photo stays visible.
Sizes
- YouTube thumbnail (16:9) — per YouTube Help, at least 640 px wide; up to 3840×2160 is now recommended. 1280×720 and 1920×1080 are common choices. Uploads from the mobile app must be 2 MB or less, and you'll be warned if a file is bigger.
- Instagram square 1:1 (1080×1080) — the safe default for posts.
- Portrait 4:5 (1080×1350) / 3:4 (1080×1440) — take up more of the feed; the profile grid now shows posts as tall 3:4 tiles.
- Stories/Reels 9:16 (1080×1920) — fills a phone screen.
- Landscape 1.91:1 (1080×566) — for wide landscape photos.
Crop or pad
With “Crop to fill”, a box in the target ratio appears on the photo; drag it to choose what stays. With several photos, use Previous/Next to adjust each — untouched photos are cropped from the center. The padding options keep the whole photo and fill the rest with a blurred copy of the photo or a solid color — perfect for putting a landscape shot in a Story or keeping everyone in a group photo.
Platforms change their specs from time to time, so check the app's guidance before posting. You'll be warned if a photo is smaller than the target and would be enlarged. Add a caption afterwards with Add Text to Photo. Photos are never uploaded.

Frequently asked questions
Instagram still crops my photo.
When picking the photo in the app, make sure the crop is set to the original ratio. If it's set to 1:1, a 4:5 photo will be cropped square.
What size should a YouTube thumbnail be?
1280×720 is sharp and small. For large screens, use 1920×1080 or more.
The blurred background is too dark.
It's slightly darkened to make the photo stand out. For a bright background, choose “Pad (solid color)” with white.
