Compress PDF for GST Returns Under 500KB (Fast & Secure)
Filing GST returns is stressful enough without technical glitches on the GST portal. One of the most common issues taxpayers face is the strict 500KB limit for document uploads.
Official Requirements & Limits
The GSTN portal has precise limits: GSTR-9 offline utility and other supporting documents usually must be under 500KB. Keeping it under 450KB is the 'safe zone' to avoid upload timeout errors.

Troubleshooting Tips
