Files Online
Open, view, zip, rename, and export files entirely in your browser. Nothing is uploaded. No server processes your data.
Drag files here or click to begin. Works in Chrome, Firefox, Safari and Edge.
Six purpose-built tools that run entirely in your browser. No account. No extension. No install.
Browse files and folders you select. Sort, filter and search by name, type, size or date. Nothing persists between sessions.
Preview text, JSON, CSV, spreadsheets, images, audio, video, PDF, and Word documents without installing anything.
Create ZIP files from any selection. Extract ZIP, TAR, and other archive formats. Repackage extracted content as a new ZIP.
Apply rename rules: find/replace, prefix, suffix, numbering, case transform. Live preview before applying. Export a rename plan.
Extract file metadata — name, size, type, modified date, path — into a CSV or JSON file. Optional SHA-256 checksums.
Save reusable operation presets locally in your browser. Load and apply rename, archive, or export configurations in one click.
Three steps. No sign-up. No waiting.
Click "Open Files" or "Open Folder" to select what you want to work with. You can also drag files directly into the browser window. No upload happens — files stay on your device.
Browse your file list, preview files in-browser, create or extract archives, batch rename with live preview, or export metadata tables.
Download processed files or archives directly to your computer. In Chrome and Edge, you can save back to a folder you've chosen. Recipes persist locally for reuse.
Everything happens in your browser. We do not operate any file processing server. Your files are never transmitted anywhere. There is no backend that could receive your data even if it wanted to.

No. All file operations happen inside your browser using standard web APIs. Your files never leave your device. There is no server involved in reading, processing, or writing your files.
The app shell works offline once cached by your browser. Libraries for archive extraction and document preview require an internet connection on first use unless you self-host the vendor files.
ZIP extraction works natively in all modern browsers via zip.js. RAR, 7-Zip, TAR and other formats are supported via libarchive.js using WebAssembly.
Recipes are stored in your browser's IndexedDB — a local database only accessible to this site. They never leave your device and are not synced across browsers or devices.
No. Files Online only works with files and folders you explicitly open in the tool. It cannot access arbitrary file system locations without your permission. Every access requires a deliberate action from you.
Chrome and Edge provide the fullest experience via the File System Access API, including the ability to save files back to a folder you've selected. Firefox and Safari work well with minor limitations around direct folder write-back.
