Common Use Cases
Visa and Immigration Applications
Many visa portals (Schengen, US, UK, Canada) require supporting documents under 1MB each. Compress your passport scans, bank statements, and cover letters to meet these strict limits.
Government Forms and ID Uploads
Government portals for tax filings, permit applications, and ID submissions often cap uploads at 1MB. Compress your documents to upload without errors.
Mobile Sharing via WhatsApp and Telegram
Sending large PDFs over messaging apps is slow and sometimes blocked. Compressing to under 1MB ensures fast delivery and easy downloading on any device.
Scholarship and University Applications
Many scholarship and admissions portals require transcripts, recommendation letters, and essays under 1MB. Compress without losing readability.

Tips for Getting Under 1MB
If your PDF is still over 1MB after compression, try these strategies:
- ✓ Split first, then compress — break a large PDF into smaller sections, then compress each one.
- ✓ Remove unnecessary pages — delete blank pages or pages that are not required for your submission.
- ✓ Use Black & White — if color is not required, convert images to grayscale before compressing (this reduces size significantly).
- ✓ Flatten the PDF — if the PDF has form fields or annotations, flatten them first to remove hidden data.
