Compress large PDFs to under 1MB. Reduce file size without significant quality loss.
Why Compress PDFs Under 1MB
Many email systems and file sharing platforms have attachment limits of 1MB. Compressing PDFs below this threshold ensures you can share files via email, upload to any platform, and store more documents with less storage.
The goal is reducing size while keeping the document readable and professional.
Compression Methods
There are several ways to reduce PDF file size:
- Image compression - Resize and compress embedded images
- DPI reduction - Lower print resolution
- Quality settings - Adjust compression level
- Font subsetting - Embed only used characters
- Object removal - Strip unnecessary elements
