How to Compress PDF Under 1MB

Why Do Websites Require PDFs Under 1MB?

Many websites enforce strict file size limits, especially job portals, email services, and government platforms.
If your PDF is larger than 1MB, uploads often fail or get rejected.

Common scenarios include:

• Resume and CV uploads
• Email attachments
• Government form submissions
• College and exam portals
• Online applications

Why PDF Files Become Large

PDF files usually grow in size due to:

• High-resolution images
• Scanned documents
• Embedded fonts and metadata
• Multiple image-heavy pages

Even a short document can exceed 1MB if it isn’t optimized.
