Resize an Image for Instagram, Facebook & LinkedIn
Every platform crops and compresses uploads its own way, so a photo that looks sharp on your phone can end up cropped oddly or soft after upload. Uploading at the platform's own recommended pixel size gives it the least reason to re-process your image.
Common sizes (pixels)
| Use | Recommended size |
|---|---|
| Instagram square post | 1080 × 1080 |
| Instagram portrait post | 1080 × 1350 |
| Instagram Story / Reel | 1080 × 1920 |
| Facebook post (shared link/photo) | 1200 × 630 |
| Facebook cover photo | 820 × 312 |
| LinkedIn post image | 1200 × 627 |
| LinkedIn cover banner | 1584 × 396 |
| LinkedIn profile picture | 400 × 400 |
| X (Twitter) post image | 1600 × 900 |
| YouTube thumbnail | 1280 × 720 |
Platforms tweak these numbers occasionally. If a specific upload still looks off after resizing, check the platform's current help page — but these values are the stable, long-standing standard for each.
Step by step
- Open the resizer and switch to Pixels mode.
- Type the width from the table above. Uncheck aspect-ratio lock if you also need the exact height (the photo is centre-cropped to fit).
- Most platforms don't enforce a KB cap, but if you want to keep uploads fast on mobile data, add an optional max size of 500KB–1MB.
- Drop your photo and download.
Why exact pixels beat "just upload the original"
Uploading a 12-megapixel original and letting the platform resize it usually works fine — but the platform's own compressor is tuned for speed, not your specific photo. Resizing yourself first, especially for text-heavy graphics or product shots, keeps you in control of what gets cropped and how sharp the result looks.
Posting several images in a batch? See the bulk resize guide — set the width once and process the whole set together.
