Formats, file types, and size limits for JS
Knowing what JS Formatter accepts makes your workflow smoother.
Supported formats
The tool accepts text and data inputs rather than uploaded files.
| Format | MIME type | Status |
|---|---|---|
| Text / data | — | Supported |
Size limits
JS Formatter processes generous file size limits. Because everything runs in your browser, the practical limit is your device's memory — not a crowded server.
Getting the best output
- Use the newest formats you can for the best quality-to-size balance
- When quality matters, choose lossless options; when sharing, choose compact ones
- Keep a backup of your original input before processing
Verdict
JS Formatter handles text and data inputs as needed and generous file size limits with no file ever leaving your device.
