Questions about scientific calculator
Yes — no watermark, no daily cap, no signup. Pro raises the file-size and batch limits, but the tool itself is not gated.

Up to 10 files at 15 MB each. Everything runs in your browser, so the real ceiling is your device’s memory — the cap keeps a large file from exhausting the tab.
