How It Works

Choose your PDF document directly from your device.

Choose between Low, Balanced, or Strong compression presets.

Instantly preview your saved space and download the compressed PDF.

Unlike cloud converters, zero bytes of your document or image are sent over the network.

No upload queue, no download wait times. Processing is powered by your own CPU & GPU.

No 50MB file size ceiling or hourly usage caps. Handle heavy files right on your hardware.

Are my files uploaded to a server for compression?

Never. Compression runs locally inside your browser using canvas rasterization and WebAssembly.

Will my document lose quality?

Our Balanced preset maintains sharp text readability while typically cutting file sizes by 40% to 65%.

Combine multiple PDF files into one document in seconds.

Extract page ranges or separate individual pages from your PDF.

Permanently rotate all or selected pages in your PDF.

Turn light PDFs into dark mode or invert colors for easy night reading.
