Resize Images by Pixels or Percentage

Why Resize Images Before Uploading or Sharing?
Adjusting your photo's visual scale helps you achieve perfect framing and guarantees compatibility across digital systems:
- Preparing images for social media: Avoid awkward automated cropping by manually scaling images perfectly to platforms like Instagram or Twitter.
- Reducing file size for uploads: Shrinking the resolution significantly minimizes overall file weight. If you also need to reduce file size after resizing, you can use our Image KB Compressor.
- Meeting upload dimension limits: Quickly comply with strict width or height limitations mandated by university portals or government gateways.
- Optimizing images for websites: Appropriately scaled pictures dramatically decrease loading times and boost site performance.
