Gazelle Social Media Resizer

Resize images for Instagram, Twitter, LinkedIn, TikTok, Facebook, YouTube, and Pinterest with one click — no signup, no watermark, no upload. Drop your image, pick a platform preset, choose cover or fit mode, and export. Everything runs in your browser using the Canvas API. Your images never leave your device.

What are the correct image sizes for social media?

Instagram Post: 1080x1080, Instagram Story: 1080x1920, Twitter Post: 1200x675, LinkedIn Post: 1200x627, TikTok: 1080x1920, Facebook Cover: 820x312, YouTube Thumbnail: 1280x720, YouTube Banner: 2560x1440, Pinterest Pin: 1000x1500. This tool has all these presets built in.

What's the difference between Cover and Fit?

Cover fills the entire target size by scaling and cropping the image — no empty space, but some edges may be cut. Fit scales the image to fit within the target size — no cropping, but may have bars on the sides or top/bottom.

Can I resize for multiple platforms at once?

Currently you resize one platform at a time. Select a preset, export, then select another preset and export again. Each export is instant.

Is my image uploaded anywhere?

No. The image is processed entirely in your browser using the Canvas API. Nothing is uploaded to a server.
