Most email providers cap attachments at 20MB–25MB, while job portals, university admissions, and government systems frequently enforce strict limits as low as 1MB or 2MB. Here is how to quickly reduce your PDF size to meet any threshold.
Understanding Common Upload Limits
- Gmail & Outlook: 25MB attachment limit.
- USCIS & Government Portals: 6MB to 12MB limit per upload.
- Academic & Job Application Portals: Often 2MB to 5MB limit.
The Quick 3-Step Size Reduction
Upload your document to PDFRack PDF Compressor. Select Recommended for general email use or Extreme if you must meet an aggressive <1MB threshold. Toggle "Convert to Grayscale" for scanned receipts and text-heavy forms to achieve an additional 30% reduction.
