PDF Compress Tool Explained
A browser-side PDF compress tool cannot do every kind of deep compression that server software can, but it can still be useful for a light optimization pass. This tool reloads the PDF structure locally and saves a rewritten copy using a more compact object-stream style where possible. Some files shrink, some stay about the same, and some may even grow slightly depending on how they were created originally. The benefit is that the workflow remains private, instant, and static-site compatible for quick local checks.
FAQ
Will every PDF become smaller?
No. Some PDFs shrink, while others may stay close to the same size.
Does this reduce image quality?
No. This pass rewrites the PDF structure rather than re-encoding images.
Is the file processed locally?
Yes. The optimization runs entirely in the browser.
