Why Use PDFBro to Compress PDF to under 100 KB
Frequently Asked Questions
How do I get my PDF under 100 KB?
Use PDFBro's 'High' compression. For text-heavy PDFs, this is usually sufficient. For image-heavy PDFs, you may also need to convert images to lower resolution first.
What if High compression still doesn't get under 100 KB?
Try splitting your PDF into smaller sections, or convert pages to images at 150 DPI and recombine them. Every page of image data adds to file size.
