About Social Image Sizer
Resize and crop images to the exact pixel dimensions required by Twitter/X, Facebook, Instagram, LinkedIn, YouTube, and Pinterest. Select a platform preset and the tool automatically scales and center-crops your image to fit. Covers profile pictures, cover photos, post images, stories, and more — all with the correct dimensions for each platform. No uploading to any server — processing happens in your browser using the Canvas API. No sign-up, no watermarks.
Why Use Social Image Sizer?
- Platform presets — one-click resize to the exact dimensions each platform requires, eliminating the need to look up pixel sizes.
- Auto center-crop — images are scaled to cover the target size and cropped from the center, preserving the most important part of the image.
- Covers all major platforms and image types — profile photos, cover images, post images, stories, and thumbnails.
- 100% private — your images are resized locally using the Canvas API. Nothing is uploaded to any server.
- No watermarks — the resized image is clean and ready for upload.
Common Use Cases
Profile photo optimization
Resize a portrait or headshot to the exact dimensions required for Twitter profiles (400x400), Facebook profiles (170x170), or LinkedIn profiles (400x400).
Cover image preparation
Prepare cover photos for Facebook (820x312), Twitter/X (1500x500), LinkedIn company pages (1128x191), or YouTube channels (2560x1440) without cropping manually in an editor.
Instagram post sizing
Resize photos to Instagram square (1080x1080), portrait (1080x1350), or landscape (1080x566) before uploading to avoid Instagram's automatic compression cropping.
Content calendar batch preparation
When posting the same content across multiple platforms, resize the same source image to each platform's required dimensions for a consistent visual appearance.
Tips & Best Practices
- 💡Always start with the highest resolution version of your image. Resizing down preserves quality; scaling up from a low-resolution source produces blurry results.
- 💡For profile photos, use a high-contrast image where your face or logo is centered — center-crop works best when the main subject is already in the middle.
- 💡Instagram story and TikTok video dimensions are 1080x1920 (9:16 portrait). Make sure your image or video fills the full vertical frame.
- 💡After resizing, platforms apply their own compression when you upload. Starting with a larger, higher-quality image helps preserve visual quality after platform compression.
How It Compares
Social media management tools like Buffer, Hootsuite, and Canva include image resizing for their supported platforms, but they require accounts and are tied to their publishing workflows. Photo editors like Photoshop require manual canvas resizing. This standalone tool is faster for one-off resizing tasks — no account, no monthly subscription, and your image never leaves your device.
