Frequently asked questions
Is Filembly really free?
Yes — every conversion is free, with no account, no watermarks and no daily caps beyond fair-use rate limiting. The only hard limit is 4 MB per file.
Are my files stored anywhere?
No. Files are converted entirely in memory and the result is streamed back in the same request. Nothing is written to disk, nothing is logged, and nothing exists on our servers after the conversion completes.
Which formats can I convert?
Documents (PDF, Word/DOCX, TXT), images (JPG, PNG, WEBP) and spreadsheets (Excel/XLSX, CSV) — 14 conversion pairs in total. The Supported Formats page lists every pair with honest notes about conversion fidelity.
Do I need to install anything?
No. Filembly runs in your browser on any device — desktop, tablet or phone. Upload a file, pick the output format, convert and download.
