Frequently asked questions
Is my file uploaded when I convert it?
No. Every free tool runs entirely in your browser — your file is never uploaded. The conversion happens on your device, so there is no server to trust with your file.
Is it really free?
Yes — the on-device converters and privacy tools are free, with no sign-up and no watermark.
Is redaction permanent?
Yes. Redaction rebuilds the PDF from flattened images with the black boxes burned into the pixels and no text layer kept — the content cannot be copied out, searched, or recovered from the file.
Do I need an account?
No — the free tools need no account. An account is only for Pro features, such as high-fidelity server conversions.
What can I convert?
Documents (Word, Excel, Markdown, HTML), images (JPG, PNG, WebP, HEIC, SVG), PDFs (merge, split, rotate, compress, redact), and data files (CSV, XLSX, JSON, YAML) — plus privacy tools that redact documents, scrub personal data from text, and strip hidden metadata.
