The Resize Workflow
- Start with high resolution — always resize down, never up
- Use our Image Resizer — preset social media templates
- Export as WebP — 30% smaller than JPEG
- Compress before upload — platforms re-compress, start smaller
Common Mistakes
- Uploading 4000px images → platforms compress aggressively
- Wrong aspect ratio → auto-crop cuts off important content
- PNG for photos → 5-10x larger than necessary
- No compression → slow upload, worse quality after platform processing
