Frequently asked questions
- How do I measure a file size?
- Drop a file into the tool or choose one from your device. File Size Meter immediately shows its size and basic file details.
- Can I check a file size from a URL?
- Yes. Paste a public HTTP or HTTPS file URL and select Check URL size. The remote server must allow browser CORS requests.
- Are my local files uploaded?
- No. Local file measurements run in your browser, so the files stay on your device and are not uploaded to GleeTool.
- Can I measure several files at once?
- Yes. Select or drop multiple files, review each result, then download one file or all selected files as a ZIP archive.
- Can the tool show image dimensions?
- Yes. When an image can be read, the tool shows its width and height alongside the file size.
