Will the text get smaller?

Slightly. A4 is narrower but taller than Letter, so content is scaled down a few percent to fit the width and centered vertically.

Can I convert A4 to Letter instead?

Yes. Use Convert A4 PDF to Letter, or choose Letter from the page size list.

Do you store or retain my processed files?

No. Online PDF Editor processes files in your browser using local memory. Your files are not uploaded to our servers, and closing the browser tab clears them from the tool.
