This rebuilds the PDF from compressed page images — best for scanned or image-heavy files. Selectable text and crisp vector graphics are flattened in the process.
Frequently Asked Questions
Is compressing my PDF private?
Yes. Compression runs entirely in your browser — your file is never uploaded to a server.
How does the compression work?
Each page is re-encoded as a compressed image, which dramatically shrinks scanned or image-heavy PDFs. You control the quality and detail level.
Will I lose quality?
Compression is lossy and flattens selectable text, so it’s best for scans and image-based PDFs. Use a higher quality setting to keep more detail.
