Upload issues
Fix common document upload and preview problems.
Symptoms
- Upload fails or times out
- Preview is blank / missing pages
- Document appears but can’t be opened
Fixes
- Confirm file format and size: try a smaller file or split large PDFs.
- Check password protection: remove passwords/encryption from PDFs before uploading.
- Retry on a stable network: flaky connections can cause partial uploads.
- Re-upload: if preview generation fails, re-upload the source file.
