When to compress PDF files
Sending documents via email
Most email services limit attachments to 25MB. Compress your PDF reports and proposals to fit within limits without splitting into multiple emails.
Uploading to document management systems
Many CMS platforms and cloud storage services have file size limits. Compressed PDFs upload faster and stay within size caps.
Reducing scanned document storage
Scanned PDFs are notoriously large. Compressing the embedded scan images can reduce archive sizes by 70-80% with acceptable quality.
Faster PDF downloads on your website
If you host downloadable PDFs (guides, whitepapers, catalogs), compressing them improves download speed and user experience.
