What metadata is removed when I select the metadata removal option?

It removes document properties such as the author, title, keywords, creator, producer, and embedded thumbnails.

Will optimizing the PDF affect its layout or visual quality?

No, the optimization process preserves all page content, text formatting, and layout structure while cleaning the underlying file data.

What does the 'Remove Object Streams' option do?

It unpacks compressed object streams, which can increase compatibility with older PDF readers, though it may slightly increase the file size.

Does this tool compress images inside the PDF?

This tool focuses on structural optimization and stream compression; it does not perform lossy downsampling of embedded images.

Is my document data secure during the optimization process?

Yes, your files are processed securely and are not stored permanently or shared with third parties.
