📖 What is the Compress PDF?
Many college enrollment portals, job boards, and emails enforce strict PDF file size limits (like 2MB or 5MB). When you scan documents using a mobile app, the output file is often too large to upload.
This browser-side PDF compressor optimizes image quality and embedded fonts to dramatically shrink your PDF size while keeping text and graphics readable.
