Tips for Using the File Info Tool
- Use the file size information to identify large images that may need compression for web use.
- Compare dimensions across images to ensure consistency before creating layouts or galleries.
- Check bit depth to understand image quality — 8-bit is standard for web, 16-bit for high-quality editing.
Frequently Asked Questions — File Info
Is the file info tool free?
Yes, completely free. No registration, no hidden charges, and no file size limits. All file analysis happens locally in your browser.
What file information is displayed?
Our tool displays: file name, exact file size (bytes/KB/MB), MIME type, image dimensions (width × height), aspect ratio, file format, color depth, bit depth, and last modification date. Image-specific data is extracted using the browser's native image decoding.
What image formats are supported?
All common web image formats are supported: JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF, SVG, and HEIC. If your browser can display it, our tool can analyze it.
Is my privacy protected?
Yes, 100%. All file analysis is performed locally in your browser using JavaScript. Your images and their data never leave your device — no uploads to any server.
Can I upload multiple images at once?
Yes, batch upload is fully supported. Upload multiple images and select each one from the list to view its individual file properties. This is great for comparing files before optimization workflows.
What does bit depth mean?
Bit depth determines the number of possible colors per pixel. 1-bit is black and white, 8-bit supports 256 colors per channel (standard for web), 24-bit is true color (16.7 million colors), and 32-bit adds an alpha transparency channel.
How is file size calculated?
The file size is read directly from your original file. It shows the exact size on disk in bytes, automatically formatted to KB or MB for readability. This is the actual storage size of the file, not an estimate.
