pdfeditor.onl/compress-pdf — Best Free Option

No daily limits. No watermarks on output. Files processed in your browser — never uploaded. Good compression: balanced quality/size. Strong compression: maximum size reduction. Works in any browser on any device.

Tip: Test both Good and Strong compression on your specific PDF — the optimal setting varies by document type and the proportion of images vs. text.
