Why Resize Images?
- Web performance — Uploading oversized images slows down websites. Resize before uploading to a CMS.
- Email attachments — Large photos can be blocked by email servers. Resize to under 1 MB.
- Social media — Each platform has optimal dimensions. Instagram posts: 1080×1080. Twitter header: 1500×500.
- Storage — Smaller images take less storage space on your device or cloud.
