Social Media Image Resizer
Free online social media image resizer. Resize any photo to the exact dimensions for Instagram, Twitter, LinkedIn, Pinterest, Facebook, and YouTube with cover or contain fit — all in your browser.
This social media image resizer crops or fits your photo to the exact pixel dimensions each platform expects — Instagram posts and stories, Twitter headers and posts, LinkedIn posts and banners, Pinterest pins, Facebook covers, and YouTube thumbnails. Pick a preset and a fit mode, and the tool produces a perfectly sized image you can download immediately. All resizing happens locally in your browser with the Canvas API, so your photos are never uploaded and remain completely private.
Use Cover to fill the frame and crop the overflow, or Contain to fit the whole image with a white background around it. Because everything runs in the browser with no external libraries, the tool is fast and works offline once loaded.
Frequently asked questions
Are my images uploaded anywhere?
No. Resizing is done entirely in your browser using the Canvas API. Your images never leave your device.
What's the difference between Cover and Contain?
Cover scales the image to fill the target size and crops whatever overflows, so there are no borders. Contain scales the whole image to fit inside the target, adding a white background to fill any empty space.
Which preset should I use for an Instagram feed post?
Use Instagram Post 1080×1080 for a square, or Instagram Portrait 1080×1350 for a taller image that takes up more space in the feed.
What format is the downloaded file?
The resized image is saved as a PNG to preserve quality.
