A .env file stores environment variables for your app — things like API keys, database passwords, and configuration settings. Flipper File's ENV File Viewer lets you open and inspect any .env file directly in your browser, with secret values masked by default so you can share your screen safely. No file is ever uploaded to a server — everything stays on your device.
How to View a .env File
- Click "Choose File" or drag and drop your
.envfile into the upload area. - Your file opens instantly — each variable is listed with its key and value in a clean table.
- Toggle secret masking — by default, values are hidden. Click the eye icon next to any row to reveal a specific value, or use "Show All" to toggle all at once.
- Search or filter — use the search box to find specific keys by name.
- Copy any value — click the copy icon next to any row to copy that variable's value to your clipboard.

Frequently Asked Questions
What is a .env file?
A .env file (short for "environment") is a plain-text configuration file used by web applications to store environment-specific settings like API keys, database connection strings, and feature flags. It keeps sensitive configuration separate from your source code.
Is my .env file safe to open here?
Yes. Your file is processed entirely within your browser using JavaScript — it is never sent to Flipper File's servers or any third party. You can verify this by opening your browser's network tab before loading a file.
Why are values hidden by default?
Many .env files contain sensitive credentials like API keys, passwords, and tokens. Values are masked by default so you can safely open and inspect the structure of your file without accidentally exposing secrets if someone is watching your screen.
Can I view .env files with comments?
Yes. Lines starting with # are recognized as comments and displayed in a distinct style so they're easy to distinguish from variable definitions.
What formats does the viewer support?
The viewer handles all common .env formats: bare values (KEY=VALUE), quoted values (KEY="VALUE" or KEY='VALUE'), multiline values, and files with or without the .env extension. It also handles blank lines gracefully.
Can I edit my .env file here?
This tool is a viewer — it's designed for reading and inspecting. If you need to edit .env files, you'll want a text editor like VS Code. The viewer does let you copy individual values to your clipboard.
What's the difference between the ENV Viewer and the ENV Validator?
The ENV Validator checks your .env file for syntax errors and formatting problems. The ENV File Viewer is focused on reading and displaying your file content in a clean, organized table with value masking — great for quickly inspecting variables without opening a code editor.
Does this work on mobile?
Yes. The ENV File Viewer is fully responsive and works on phones and tablets, though the table layout is best enjoyed on a wider screen.
