How to Compress PDF Files Without Losing Quality
Large PDF files can be a real headache when sharing via email or uploading online. The good news is you can significantly reduce file size without visible quality loss using the right techniques and tools.
Why PDF Files Become Large

Lossy compression achieves greater size reduction by slightly reducing image quality. For most business documents lossless compression provides sufficient size reduction.
