About RayoPDF

RayoPDF is a free online PDF compressor with one job: make your PDF files smaller, fast, without touching your privacy.

What it does

Drop a PDF into the compressor and it re-encodes oversized images, rebuilds the document structure more efficiently, and hands you back a lighter file — with the same pages, order, text and orientation. You choose how hard it squeezes: Low, Medium, High or Maximum.

How it works

Everything happens directly in your browser. Your file is read into your device's own memory, processed locally with standard web technologies, and downloaded straight back to you. There is no server upload step at all — which is also why the tool feels instant.

The philosophy

• Drop. Compress. Go. Three steps, no settings maze.
• Private by design. Files that never leave your device can't leak.
• Honest results. If your PDF is already optimized, you get the original back — never a heavier file.
