Introducing Our New Advanced PDF Compression Endpoint

We’re excited to announce the very first of our next-generation endpoints — /v2/pdf/compress — bringing massive improvements to PDF compression and performance.

Thanks to an upgraded engine based on PyMuPDF technology, the new /v2/pdf/compress endpoint can shrink your PDF files up to 40% smaller compared to the previous /v1/pdf/optimize endpoint — all while maintaining excellent visual quality.

Whether you’re optimizing for bandwidth, speed, or storage, this marks a big step forward in our mission to make PDFs faster, lighter, and easier to work with.

Important Update

The old /v1/pdf/optimize endpoint is now deprecated. While it remains available for use, we strongly recommend migrating to the new /v2/pdf/compress endpoint for better performance and future compatibility.

How It Works

Instead of using /v1/pdf/optimize, simply send your files to the new /v2/pdf/compress endpoint.

  • Default settings: Expect PDFs around 20% smaller than before.
  • Maximum compression: Achieve up to 40% smaller file sizes.

The new engine ensures faster processing, better compression ratios, and higher overall efficiency without sacrificing how your PDFs look.

Zapier and Make.com Users

New users will use the new compression endpoint by default. If you were using the older optimize action, you will have the option to transition to the new endpoint.
