- How does local PDF compression work?
- Compress PDF will re-encode embedded images at a lower quality via the Canvas API and strip unnecessary metadata, all inside your browser using pdf-lib.
- Will compressing my PDF reduce quality?
- You will be able to choose a compression level that trades off file size against image quality, similar to server-based compressors, but without uploading anything.
