Why PDFs get too big
PDFs balloon when they contain high-resolution images, embedded fonts or scanned pages. Compressing re-encodes these elements to remove waste while keeping the content readable.
Step-by-step
- Open the Compress PDF tool.
- Drop your PDF into the upload area.
- Pick a level — Recommended works best for most files.
- Click Compress and download instantly.
