Top 5 Ways to Compress PDF Files Online
Large PDF files can be a headache. They clog up email inboxes, take forever to upload, and eat up storage space. Fortunately, compressing PDF files is easier than ever with modern online tools.
Why Do PDFs Get So Big?
PDFs often contain high-resolution images, embedded fonts, and uncompressed data streams. While this ensures high quality for printing, it's often unnecessary for screen viewing or emailing.
How Compression Works
PDF compression algorithms work by:
- Downsampling images (reducing their resolution)
- Removing unused fonts and metadata
- Compressing text streams and structural data
