Free Online Image Resizer for Social Media
Every social media platform has its own image size requirements, and posting the wrong dimensions means your images get cropped weirdly or look blurry. A good image resizer takes the guesswork out of this by giving you exact presets for every platform.
Why Image Dimensions Matter on Social Media
Instagram crops your image to a square if it doesn't fit. Facebook squashes wide images into tiny thumbnails. LinkedIn preview images get cut off at the edges. Each platform has specific aspect ratios and pixel dimensions that make your content look its best.
I used to just upload whatever size image I had and hope for the best. The result? Blurry profile photos, chopped-off text in cover images, and post images that looked way different than what I designed. Not anymore.
Built-In Social Media Presets
The image resizer includes presets for all the major platforms, so you don't need to memorize any numbers:
- Instagram — Square post (1080×1080), Portrait (1080×1350), Story (1080×1920), Reel cover (1080×1920)
- Facebook — Post (1200×630), Cover photo (820×312), Profile (170×170), Event cover (1920×1005)
- Twitter/X — Post (1600×900), Header (1500×500), Profile (400×400)
- LinkedIn — Post (1200×627), Cover (1128×191), Profile (400×400)
- YouTube — Thumbnail (1280×720), Channel banner (2560×1440)
Custom Sizes Too
Not everything is for social media. Sometimes you just need to resize a photo to specific pixel dimensions for a website, a presentation, or an email. Type in any width and height you want, or use the percentage scaler to shrink images proportionally.
The tool preserves aspect ratio by default (so your images don't get stretched), but you can override that if you specifically need a non-proportional resize.
Quality Settings
You also get control over output quality. Need a small file size for a website? Drop the quality to 70-80% and you'll barely notice the difference visually. Need pixel-perfect output for print? Keep it at 100%. The preview shows you exactly what the output will look like before you download.
Batch Processing
This is the feature I didn't know I needed until I had it. Drop multiple images in and resize them all to the same dimensions at once. Super useful when you're prepping a bunch of product photos or creating a series of social posts.
Everything runs in your browser — images aren't uploaded to any server. That matters when you're working with client photos or unreleased product images.
