FAQ
Do these specs change?
Platforms occasionally update their recommended dimensions. We keep this guide updated. The fundamentals (like 1080×1080 for Instagram squares) rarely change.
What file format should I use?
JPEG for photos (smaller file size), PNG for graphics with text or transparency, and WebP for the best compression. Most platforms accept all three.
What happens if I upload the wrong size?
Platforms will crop or scale your image, often cutting off important content. Using the correct dimensions ensures your full image displays as intended.
