About File Size Checker
The file size checker reads file metadata locally to display sizes without uploading. Useful for checking sizes before upload (avoiding failed uploads due to size limits), verifying export sizes, or calculating storage requirements.
Displays sizes in bytes, kilobytes (KB), megabytes (MB), and gigabytes (GB) simultaneously. For multiple files, shows individual sizes and total combined size.
File reading uses browser FileReader API to access metadata only, no file content is read or uploaded. Perfect for checking sensitive files, large media, or confidential documents before sharing or uploading.
