Social Image Resizer

Resize images for Instagram, TikTok, YouTube, X, LinkedIn, and more. Choose presets, fit mode, and export instantly in your browser.

How to use this tool

  1. Upload an image and choose a platform preset.
  2. Select fill/crop or contain mode with optional background color.
  3. Generate preview and download in PNG/JPG/WebP.

Preset benefits

  • Platform-specific dimensions reduce automatic crop surprises.
  • Consistent exports simplify cross-channel publishing workflows.
  • Custom mode supports any campaign or ad requirement.

Output guidance

  • Use cover mode for edge-to-edge designs with controlled cropping.
  • Use contain mode to preserve full composition without cut-off.
  • PNG best preserves transparency; JPG/WebP reduce file size.

FAQ

Can I resize to custom dimensions?
Yes. Select the Custom Size preset and edit width/height.
Why is part of my image cropped?
Fill mode intentionally crops to match target aspect ratio. Switch to contain mode to keep the whole image.
Is processing local?
Yes. Resizing and export are browser-side.
