FAQ

Common questions

What file types does CopyFile support?

Every single one. CopyFile treats your file as raw binary data and duplicates it exactly — no conversion, no processing. PDFs, images, videos, executables, archives, fonts, spreadsheets… anything goes.

Is there a file size limit?

There's no hard limit enforced by CopyFile. The practical ceiling depends on your browser and available RAM. For very large files with thousands of copies, the resulting ZIP can consume significant memory — a warning is shown when the estimated output exceeds 500 MB.

Does my file get uploaded to your servers?

No — and there are no servers to upload to. Every operation happens inside your browser using JavaScript. Your file data never leaves your device.

Can I copy a file more than 999 times?

Yes! The slider is capped at 999 for convenience, but the number input below it accepts any positive integer — type 5,000 or 50,000 if you need. Just be mindful of the resulting ZIP size.

How are the copies named inside the ZIP?

Each copy keeps the original filename with a zero-padded number appended — for example, report.pdf becomes report_001.pdf, report_002.pdf, and so on. This keeps them sorted correctly in any file manager.

Is CopyFile really free?

Completely. No registration, no subscription, no watermarks, no usage limits. Open the page and go.
