What this tool does

This browser-based compressor rasterizes pages for predictable size reduction. That can greatly reduce image-heavy files, but selectable text may become image content.

Frequently asked questions

Will text stay selectable?

Not necessarily. This compression method rasterizes each page, so text can become part of a page image.

Why can a compressed PDF sometimes be larger?

Already-optimized or mostly-vector PDFs may not shrink with rasterization. PDFbrix tells you when the new file is not smaller.

Are files uploaded for compression?

No. The included compressor runs locally in your browser.
