How the compressor protects quality

The tool starts with the least destructive approach. Best Quality rewrites the PDF structure without intentionally reducing image quality. Balanced and Smallest Size can render pages to compressed images when stronger size reduction is needed.

Target a specific upload limit

Enable Target file size for limits such as 2 MB or 500 KB. The browser tries progressively stronger settings and stops at the highest-quality candidate that reaches the target. Exact size cannot be guaranteed because PDFs vary widely.

What stays private?

Your selected PDF is read into browser memory and the result is created locally. No account is required. Third-party JavaScript libraries are fetched by the page, but the PDF itself is not sent to those library hosts for processing.
