The Complete Image Resize Guide for Every Social Network

Cheat sheet of every social media image size in 2026 — Instagram, TikTok, LinkedIn, Twitter, YouTube — plus a free tool to resize them in one click.

Why Image Size Matters

Posting the wrong-sized image to a social network usually results in awkward cropping. The platform fits your image into its slot however it wants — and what looked perfect on your computer ends up cropped, blurry, or stretched.

The 2026 Cheat Sheet

Instagram

  • Square post: 1080 × 1080

How to Resize Instantly

  1. Open the Image Resizer
  2. Drop your photo
  3. Click a social media preset, or type your own dimensions
  4. Click Resize

The tool runs entirely in your browser, so even high-resolution photos process in under a second.

Tips

  • Aspect ratio matters — if you're going from a 16:9 photo to a 1:1 square, you'll lose part of the image. Use Crop Image first to choose what stays.
  • Compress after resizing — once dimensions are right, run the result through the Image Compressor for an extra size reduction.
  • Keep originals — always resize a copy and keep your high-res master.
