Crop or pad a photo to the exact size each platform wants: Instagram 1080×1350, YouTube 1280×720, X, Facebook, LinkedIn, TikTok.
How to use
- Choose a photo or drop it in. You can paste a copied photo too.
- Pick a platform preset or choose Type your own and enter a width and height (16–6,000 px). Presets: Instagram 1080×1080, 1080×1350, 1080×1440 and 1080×1920; YouTube 1280×720 and 2560×1440; X 1600×900, 1500×500 and 400×400; Facebook 820×312; LinkedIn 1200×627 and 1584×396; TikTok 1080×1920; KakaoTalk 720×720.
- Choose a fit mode. Cover crops around the centre of the photo to fill the frame; Contain keeps the whole photo and fills the rest with your background colour (white, light grey, custom, or transparent for PNG).
- Set the file format (JPEG, WebP or PNG) and quality (50–100%); the preview and estimated file size update.
- Press Download. The file name includes the preset and the pixel size.
FAQ
What is the difference between Cover and Contain?
Cover crops around the centre of the photo so the frame is completely filled; Contain keeps the whole photo visible and fills the rest with the background colour. You cannot choose the crop position in Cover, so crop it first in Change Image Aspect Ratio if you need to.
What size should an Instagram image be?
At 1080 px wide: square 1080×1080, portrait 4:5 1080×1350, portrait 3:4 1080×1440, and Stories or Reels 9:16 at 1080×1920. Since the 2025 profile grid change to 3:4, a 4:5 post is cropped at the sides in the grid, so keep key content in the middle.
What is the YouTube thumbnail size?
1280×720 (16:9). YouTube Help asks for a width of at least 640 px, 16:9, in a common format such as JPG or PNG, and recommends larger sizes like 3840×2160 (use Type your own). Uploads can be up to 50 MB from a computer and 2 MB from the mobile app.
Are there X, Facebook and LinkedIn sizes?
X: post 1600×900, header 1500×500, profile 400×400. Facebook: the cover as shown on a computer, 820×312 (phones show it at 640×360, so the sides are trimmed). LinkedIn: post 1200×627 and profile banner 1584×396.
What if my size is not listed?
Choose Type your own and enter a width and height between 16 and 6,000 px, for example 640×640 for a KakaoTalk channel profile.
Can I see the file size before saving?
Yes. The estimated file size for the chosen format and quality is shown with the output size. JPEG and WebP can be reduced with the quality slider; PNG has no quality setting.
How are big photos and transparent PNGs handled?
Photos longer than 4,000 px on the long side are scaled down to 4,000 px first. Output can be set up to 6,000 px, but enlarging beyond the original does not make it sharper. Transparent areas turn white when saved as JPEG; with Contain and PNG you can keep them transparent.
