File sizes are validated before uploading. Files that exceed a platform's limit will be rejected.
When posting to multiple platforms at once, the strictest limit applies to all files in the request.
Compressed files generally upload faster and are less likely to hit size limits. Consider optimizing media before uploading.
Social networks may update their limits at any time. We keep this page aligned with the latest behavior observed in production.
