EnglishWhat Is FilesMD? File Metadata Viewer and Editor Explained
Updated
FilesMD is a browser-based metadata viewer and editor. You upload a file, and it shows the embedded metadata and EXIF fields — timestamp, thumbnail, software version, language, author, GPS location, original document ID, and more — with the option to edit those fields. It works with a very wide range of file types, so it is useful when you need to inspect what a file carries inside it without installing desktop software.
What you can do with it
The tool is built around one workflow: upload a file, read its metadata, and change it if needed.
- View metadata and EXIF fields. After upload, the tool extracts fields such as timestamp, thumbnails, software version, language, author, GPS location, and original document ID.
- Edit metadata. The page is labeled "View/Edit File Metadata," so editing is part of the intended use, not just reading.
- Work across many formats. Support covers photos, video, audio, documents, archives, and other binaries — far beyond the usual JPEG-only metadata tools.
Supported file types
The upload area accepts "(almost) any type of file." The listed categories and examples are:
| Category | Examples from the supported list |
|---|---|
| Photo | jpg, png, gif, tif, webp, heic, heif, raw, dng, cr2, cr3, nef, arw, psd, svg, xcf |
| Video | mp4, mov, avi, mkv, webm, wmv, flv, mts, mxf, 3gp |
| Audio | mp3, flac, wav, m4a, ogg, wma, aiff, ape |
| Document | pdf, docx, xlsx, pptx, epub, mobi, html, json, txt, rtf, csv, pages, numbers, key |
| Compressed | zip, 7z, rar, gz, tar, iso |
| Other | dll, exe, lnk, torrent, ttf, otf, woff, xmp |
If your format appears in the list, assume the tool will attempt to read its metadata. The list is long but not literally every extension, so check before relying on it for an unusual format.
How to use it
- Open filesmd.com.
- Drag and drop a file onto the upload area, or click to select a file from your device.
- Wait for the extraction to finish. The tool displays the metadata and EXIF fields it found.
- Review the fields you care about — for example, GPS location on a photo, author on a document, or software version on an exported image.
- If you need to change a field, use the edit function and then save or export the result.
The expected result is a readable list of metadata fields for that file, plus the ability to modify them.
When it is a good fit
- Checking a photo before sharing it. GPS location and timestamps are common fields people want to see before posting an image publicly.
- Verifying document authorship. Author and software version fields can tell you what produced a PDF or Office file.
- Inspecting media files. Video and audio files often carry container metadata that is hard to read without a dedicated tool.
- Quick checks without installing anything. Because it runs in the browser, it suits one-off inspections on a machine where you cannot install software.
Things to keep in mind
- Upload means the file leaves your device. The workflow is upload-based, so treat it as sending the file to a service rather than processing it locally.
- Not every field exists in every file. A plain text file will not have GPS data; a screenshot may have no author field. What you see depends on what the file actually contains.
- Editing changes the file's embedded data, not its content. Changing a timestamp or author field does not alter the image, audio, or document content itself.
- Very large or unusual files may behave differently. The supported list is broad, but extraction quality varies by format and by how the file was created.
If you only need to read metadata occasionally and want broad format coverage in a browser, FilesMD fits that job. If you need to process sensitive files without uploading them, a local desktop tool is the better choice.
