Why Do Upload Portals Limit PDF Sizes to 2MB or 10MB? File Limitations

Job Application Portals
Many recruitment and academic portals limit resume, CV, or portfolio uploads to under 2MB to keep candidate files manageable.
Tax Filing Platforms
When uploading supporting documents or scanned receipts for tax returns, systems strictly enforce small size caps for data management.
Email Attachment Limits

Frequently Asked Questions (FAQ) - PDF Compression
Q: Will compressing my PDF make the text blurry?
No, printed text remains perfectly sharp. The tool only compresses embedded images while leaving vector text layers untouched.
Q: Why did the tool return my original file without changes?
This happens if your original PDF is already highly optimized (vector-based). Forcing compression would only increase the file size, so our smart fallback returns the original to preserve the best quality.
