When to Use This Tool
Email attachments
Most email providers limit attachments to 10–25 MB. Compress large PDFs to send without needing a file-sharing service.
Uploading to portals
Government, legal, and HR portals often cap document uploads. Compression gets your file under the limit.
Mobile-friendly sharing
Smaller PDFs download faster on mobile data and take less storage — important when sharing documents with many recipients.
Long-term archiving
Reduce storage costs by compressing archives of old reports, invoices, and records.
