Social Media Image Sizes
Every platform crops and scales uploads differently. Starting with the correct dimensions avoids blurry edges, awkward crops, and rejected ads. This resizer includes one-click presets for LinkedIn posts (1200×627), Instagram square and story, X headers, YouTube thumbnails, and Facebook posts — plus a custom tab when you need exact pixels or a percentage scale.
Unlike cloud resizers, your marketing assets and client photos never leave your device. Batch an entire folder of campaign creatives and download one ZIP. Shareable URL parameters remember your preset and quality settings for repeatable workflows.
Fit Modes Explained
- Cover — fills the target frame by center-cropping (best for hero images).
- Contain — fits the entire image inside the frame with letterboxing.
- Stretch — forces exact width and height (may distort).
