How to Compress PDF and Reduce PDF File Size

Use the Compress tab to reduce PDF size for portals with strict file size limits. Upload your PDF, choose a compression level, and download the smaller file. Low compression keeps the best quality with modest size reduction - good for already-small PDFs. Medium compression reduces PDF file size by 40-70% while keeping text and photos readable at normal zoom - ideal for most government form uploads. High compression gives the smallest file size with some image quality reduction - best when you need to compress PDF to 100KB or compress PDF to 200KB. After compressing, open the file to verify all text and signatures are readable before uploading. Use the Image Resizer if you need to compress individual photo files before converting to PDF.
