How to compress a PDF online
Upload your PDF using the box above, choose a compression level, then click Compress PDF. Your smaller file downloads automatically — the original page count and layout are preserved, only the file size changes.
Which compression level should I choose?
Low gives you the smallest possible file, useful for email attachments or upload limits. Medium balances size and visual quality for most everyday use. High keeps images and text looking closest to the original while still reducing size.
💡 Tip: compressing scanned pages? Try Low first — scanned PDFs usually shrink the most without a noticeable quality difference.
