DirectF is a free file manager and converter that runs entirely in your browser. No account. No cloud. No data collection. Ever.
Store and organize files directly in your browser's local storage. Persistent across sessions — no server needed.
Convert images, PDFs, CSVs and more. PNG → JPG, PDF → TXT, CSV → JSON and back — all offline, instantly.
Chain conversions together visually. Build custom pipelines — convert, filter, rename, zip — in one click.
Files are compressed with zlib on upload to save space in your browser, decompressed transparently on download.
Preview images, PDFs and text files directly in the app without downloading anything first.
Add custom tags and notes to any file for easy searching and organization across your library.
Tap the + button and pick files from your device. Any format, any size your browser can handle.
Convert to another format, add tags, build shortcuts, or just browse. It's all instant and local.
Download the result any time, or let it live in your library for the next visit. Your browser stores it.
DirectF runs entirely in your browser using IndexedDB for local storage. No files are ever uploaded to a server. No analytics. No tracking pixels. Not even an account is required.
