How to Compress a PDF to 100KB or Less

In today's fast-paced digital world, large files are a major roadblock. Whether you're trying to email a document, upload it to a website, or simply save space on your hard drive, knowing how to compress a PDF to 100KB or less is a crucial skill. At PDFVertex, we've developed a powerful and secure online PDF compressor that allows you to reduce your file size without sacrificing quality.

Why is it Important to Compress Your PDFs?
