Why use FileView?
Most online file converters ask you to upload your document to their server first — which means a copy of your file sits on someone else's machine, even if only briefly. FileView works differently: every file you open is read and converted directly inside your own browser using JavaScript. Nothing is uploaded, nothing is stored, and there's no account to create. Close the tab and it's gone. That makes it a practical choice for viewing resumes, contracts, spreadsheets or exports that you'd rather not hand to a third-party server, while still getting instant conversions between formats like CSV, JSON, XLSX, XML, YAML and Markdown.
Frequently asked questions
Is FileView safe to use with sensitive files?
Yes. FileView processes every file entirely inside your own browser using JavaScript. Files are never uploaded to a server, so nothing leaves your device.
Do I need to create an account to use FileView?
No. FileView requires no signup, no login, and no installation. Just open the site and drop in a file.
What file formats does FileView support?
PDF, DOCX, XLSX, XLS, CSV, TSV, JSON, XML, YAML, HTML, Markdown, common image formats (PNG, JPG, WEBP, GIF, SVG, BMP, TIFF), and 15+ programming languages for code viewing.
Is there a file size limit?
FileView accepts files up to 100MB. Since everything runs in your browser, very large files may take longer to process depending on your device.
