Social Media Image Size Guide
Using the correct image dimensions for each social media platform is crucial for making your content look professional. Images that are the wrong size get cropped awkwardly, appear blurry, or lose important details.
Instagram uses square 1080x1080 for feed posts and 1080x1920 for Stories and Reels. TikTok videos should be 1080x1920 (9:16). YouTube thumbnails work best at 1280x720, while channel banners need 2560x1440.
Twitter/X posts display best at 1200x675, with headers at 1500x500. Facebook recommends 1200x630 for posts and 820x312 for cover photos. LinkedIn posts should be 1200x627, with banners at 1584x396. Pinterest pins perform best at 1000x1500 (2:3 ratio).
This tool processes everything in your browser using the HTML Canvas API. Your images are never uploaded to any server, ensuring complete privacy.
Make every post stand out
Perfectly sized images are just the start. Grow your reach with SocialBooster.
Try SocialBoosterEvery network crops, compresses, and reframes your visuals differently, so an image that looks perfect on your desktop can end up blurry or awkwardly cut off once it hits a feed. This free social media image resizer fixes that in seconds. Drop in any JPG, PNG, WebP, or GIF, pick a platform preset, and export a pixel-perfect file ready to post. Because everything runs in your browser with the HTML Canvas API, your photos never touch a server, which keeps sensitive or unpublished content completely private.
Get the right social media image dimensions every time
Guessing the correct Instagram image size or YouTube thumbnail size wastes time and often produces stretched, pixelated results. Instead of memorizing a spreadsheet of numbers, you select a ready-made preset and the tool handles the math. Each preset matches the aspect ratio the platform actually displays, so your subject stays centered and nothing important gets clipped. The most popular social media image dimensions covered here include:
- Instagram: 1080x1080 square posts, plus 1080x1920 for Stories and Reels.
- TikTok: 1080x1920 full-screen vertical video and cover images.
- YouTube: 1280x720 thumbnails and 2560x1440 channel banners.
- Twitter/X: 1200x675 in-feed posts and 1500x500 profile headers.
- Facebook, LinkedIn, and Pinterest: post, cover, banner, and 1000x1500 Pin sizes.
How to resize and crop an image
The workflow takes under a minute and never requires an account or an upload. Follow these steps to resize and crop your image for any channel:
- 1. Drag a file into the upload box or click to browse from your device.
- 2. Choose a platform preset, or switch to Custom Size to enter an exact width and height in pixels.
- 3. Pick a fit mode: Cover crops to fill the frame, Fit pads the image with a background color of your choice, and Fill stretches it edge to edge.
- 4. Preview the output live, then download a clean PNG named for the platform and size.
Because the built-in image cropper works from the center outward, faces and focal points usually stay in view. If a specific crop is cutting off something important, switch to Fit mode so the whole picture is preserved inside a padded canvas.
Why correct sizing matters for reach
Properly sized visuals do more than look tidy. When your image already matches a platform's native ratio, the network applies less compression, so details stay crisp and text remains legible. Consistent dimensions also make a profile grid or campaign feel intentional and on-brand, which builds trust with new followers. For creators and marketers running the same asset across several networks, this social media image resizer removes the tedious step of re-cropping in heavy design software. Here are a few practical tips to get the most from it:
- Start from the largest platform you post to, then resize down to keep quality high.
- Leave breathing room around key elements so cover crops never clip logos or captions.
- Use the Fit mode background color to match your brand palette when padding portrait or landscape shots.
- Batch your content by exporting each platform version before you sit down to schedule posts.
Frequently asked questions
Is this social media image resizer free to use?
Yes. The tool is completely free with no sign-up, watermark, or usage limit. You can resize and crop as many images as you like for Instagram, TikTok, YouTube, and every other supported platform.
Are my images uploaded to a server?
No. All resizing happens locally in your browser using the HTML Canvas API. Your files never leave your device, which makes the tool safe for private, sensitive, or unreleased content.
What is the best Instagram image size?
For feed posts, use 1080x1080 pixels (a 1:1 square). Stories and Reels look best at 1080x1920 (9:16 vertical). Both presets are built in, so you can export the right Instagram image size in one click.
What size should a YouTube thumbnail be?
The recommended YouTube thumbnail size is 1280x720 pixels at a 16:9 aspect ratio. Select the YouTube Thumbnail preset and the tool will crop or pad your image to those exact dimensions.
What image formats can I upload and download?
You can upload JPG, PNG, WebP, and GIF files. The resizer exports a high-quality PNG, which preserves sharp edges and supports transparency when you use Fit mode without a solid background.
How is Cover different from Fit and Fill?
Cover crops your image to completely fill the target size without distortion. Fit scales the whole image to fit inside the frame and pads the empty space with a color you choose. Fill stretches the image to the exact dimensions, which can distort the aspect ratio.
