How does PDF compression work?
NeatKit compresses your PDF by re-rendering each page as an optimized JPEG image and rebuilding the document. This is especially effective for image-heavy PDFs and can dramatically reduce file size. All processing happens in your browser — your files are never uploaded to a server.
Will compression affect quality?
The compression is lossy — text is rasterized into images, so the output is best for viewing and sharing rather than editing. Lower compression preserves more detail, while higher compression produces smaller files with some visible quality reduction. Choose the level that best fits your needs.
How much can I reduce the file size?
Results vary depending on the content of your PDF. Image-heavy documents can see reductions of 50–80%, while already-optimized or text-only PDFs may see smaller improvements. In rare cases the output may be larger than the original — NeatKit will let you know if that happens.
