Compress a PDF Free
Compress a PDF free — genuinely free. No credit card, no trial countdown, no watermark on your output. Reduce PDF file size without losing quality.
Most “free” PDF tools aren't really free — they cap file sizes, count your jobs, or stamp a watermark on the result. This one has none of those limits: compress up to 20 PDFs per job, as often as you like, with clean output every time.
The tool is funded entirely by optional premium plans for heavy users. For everyday compressing, the free tier is all you need.
