Disclosure: I'm part of the team that builds Filewhisk. Submitting our own tool.
Name: Image Metadata Viewer (Filewhisk)
URL: https://filewhisk.com/view-image-metadata/
Suggested section: Image/Video → Metadata
Cost: Free, no account, no usage limits. Supported by ads on the page (never inside the tool).
Source: Not open source. It is plain client-side JavaScript, so the code that runs can be inspected in the browser's developer tools.
What it does
Reads the EXIF block of a JPEG and shows camera make and model, software, lens, date taken, ISO, aperture, shutter speed, focal length, flash, orientation and GPS coordinates (with altitude when present). If GPS is found, it links to the location on OpenStreetMap.
Why it may be relevant
The file is parsed entirely in the browser with the File API — it is never sent to a server. For a sensitive image that a researcher does not want to hand to a third-party service, this avoids the upload step that most web-based EXIF viewers require.
How to verify there is no upload
Open the page, then disconnect from the internet (or set the browser's Network tab to Offline) and drop in a JPEG. The metadata is still read and displayed. The Network tab also shows that no request carries the file.
Limitations
- JPEG only. HEIC, PNG and WebP files are not parsed.
- EXIF only — XMP and IPTC fields (captions, credits, edit history) are not shown.
- Metadata can be edited or stripped. Most social networks and messaging apps remove EXIF on upload, so images downloaded from them usually show little or nothing. Missing or present metadata does not by itself prove where or when a photo was taken.
- The OpenStreetMap link is an external request made only if the user clicks it.
Thanks for maintaining the toolkit.
