Make a PDF smaller without uploading it. The optimizer rebuilds the file, packs its objects into compressed object streams, and compresses any page content that was saved uncompressed. You see the before and after size, and nothing is downloaded if no smaller file is possible.
It depends on how the PDF was made. Files exported without compression can shrink a lot; PDFs that are already optimized may not get smaller at all.
No. Embedded images are left exactly as they are, so quality does not change. That also means image-heavy or scanned PDFs usually shrink only a little.
You'll see a message saying the file is already well optimized, and no file is downloaded.
Your PDFs never leave your device. The files are opened and processed by JavaScript in your browser, and the result is saved straight to your downloads — nothing is uploaded to AblePro or any other server.
