Compress PDF FAQ
Not every PDF can reach this narrow target range without changing image quality. The tool accepts only a candidate inside the target range; if no suitable candidate is found, it tells you instead of pretending that the target was reached.
The compression engine uses Ghostscript PDF rewriting rather than rendering every page into a JPEG image. Text and vector elements are therefore not intentionally flattened into page images. Image-heavy PDFs can still require image downsampling to reach a small target size.
No. This page is designed for browser-side processing with WebAssembly. Your PDF is kept in the browser during compression.
The browser needs to download and initialize the Ghostscript WebAssembly engine the first time. Later use can be faster because the browser may reuse its cached resources.
