Compress PDF
Reduce PDF file size without losing quality for easier sharing and uploading.
iLovePDF
All-in-one PDF toolkit.
Best compression rates with quality control. Free tier allows multiple files, fast processing, and maintains readability. Most popular PDF tool.
Why I picked this:
iLovePDF is my top choice for PDF compression because it offers the best balance of file size reduction and quality preservation. I've compressed dozens of PDFs, and it consistently reduces file sizes by 50-70% while maintaining readability. The free tier is generous, and the processing is fast. For sharing PDFs via email or uploading to websites, it's essential.
Adobe Acrobat
Official PDF compression.
Adobe's built-in compression tool. Best quality preservation, but requires subscription. Part of their comprehensive PDF suite.
SmallPDF
Simple PDF compression.
Clean interface, fast compression. Free tier with file size limits. Good alternative to iLovePDF but fewer features overall.
