Use case
Fix PDF Upload Errors for Google Classroom
Resolve classroom and LMS PDF upload failures caused by large size, unsupported structure, or mixed document quality.
Implementation guidance
LMS and classroom uploads fail for predictable reasons: file-size limits, unstable document structure, or poor scan quality. Most issues can be resolved by standardizing format and reducing size before upload.
A reliable flow is to convert source files to PDF, compress to the required threshold, and verify that page orientation and text readability are correct. This prevents last-minute submission failures.
