Why Are PDF Files So Large?
Oversized PDFs usually have one of three causes: high-resolution images embedded unnecessarily, fully embedded fonts instead of subsets, or hidden layers and metadata. PDF compression intelligently addresses all three without affecting text readability or searchability.
When Should You Compress a PDF?
- Sending as an email attachment (most services cap attachments at 25 MB).
- Uploading to a platform with a file size limit.
- Sharing reports or presentations via WhatsApp or Telegram.
- Speeding up PDF loading on websites.
