Are my PDFs uploaded?

No. Reading, rendering, editing, and exporting happen locally in your browser.

Can PDF Studio open password-protected files?

Not yet. Encrypted files return a recoverable error instead of being uploaded or partially processed.

Does Optimize structure compress images?

No. It writes PDF object streams and removes unused copied structure. It does not reduce image quality or promise a smaller file.

What image files can become a PDF?

PNG and JPEG images are supported. Each image becomes one page and keeps its original aspect ratio.
