This browser-based EXIF Viewer can inspect common metadata embedded in a local JPG or JPEG up to 25 MiB, parsing the file in the current tab without uploading the image. The workflow is browser-based, but iPhone compatibility and iPhone file-picker support are not verified; any iPhone-specific references below apply only to browsers that allow local file selection. That makes it practical for checking camera details, capture settings, timestamps, orientation, lens information, and GPS coordinates without installing a separate iPhone app.
For a quick check, open EXIF Viewer in a browser and select a local JPG or JPEG to review recognized EXIF fields in a table. A browser-based viewer is useful when you want a table of recognized EXIF fields or need to inspect an original JPEG that is not already in the photo library.
There is an important format caveat: this viewer reads JPEG EXIF, not HEIC. A social-media download may also have had its metadata removed. The local file you select therefore determines which information can appear.
What You Can View on an iPhone
The EXIF Viewer focuses on common metadata embedded in a local JPEG. It scans the JPEG’s APP1 Exif segment, validates the embedded TIFF header, follows bounded metadata directories, and presents recognized fields in a plain table. The image bytes and parsed values remain in the current browser tab, and viewing the file does not modify it.
| Option | What it provides | Best suited for | Main limitation |
|---|---|---|---|
| Local file selection | A local JPG or JPEG selected in the browser | Supplying a JPEG for metadata inspection | JPG or JPEG only, up to 25 MiB |
| EXIF Viewer in an iPhone browser | Recognized common JPEG EXIF fields in a table | Inspecting a local JPEG and checking GPS data | JPG or JPEG only, up to 25 MiB; proprietary maker notes are ignored |
| Desktop ExifTool | Broader inventories, maker notes, and batch export | Unsupported formats, detailed investigation, and forensic work | Requires a maintained desktop setup rather than an iPhone browser workflow |
The table displays only fields the viewer recognizes and the selected file contains. A JPEG may contain none, some, or all of the supported fields, so an empty or partial result does not automatically mean the image was taken without a camera or location settings.
Read a JPEG on Your iPhone
- Open the viewer. In your iPhone browser, go to the EXIF Viewer page. This is a browser-based workflow rather than a native App Store application.
- Choose the original image. Tap the file-selection control and use the browser’s picker to select a local JPG or JPEG. Prefer the original file over a screenshot or a compressed copy from a messaging or social platform, because those copies can contain missing or changed metadata.
- Confirm the format and size. The selected file must be a JPG or JPEG no larger than 25 MiB. Renaming another format does not convert it. The viewer does not read HEIC, PNG, WebP, RAW, video, or full XMP and IPTC metadata.
- Select the file for scanning. After confirmation, the page locates the first valid Exif APP1 segment, validates its TIFF header, and follows bounded metadata directories. It handles common EXIF value types and never executes metadata found in the file.
- Review the recognized rows. Look for camera make and model, orientation, software, original and modified capture times, exposure time, f-number, ISO, focal length, pixel dimensions, lens model, and GPS latitude and longitude. Not every photograph will contain every field.
- Check sensitive fields before sharing. Pay particular attention to GPS rows. For maker notes, unsupported formats, complete inventories, or forensic evidence, move to a maintained desktop metadata tool such as ExifTool and preserve the original file.
If no fields appear, the JPEG may have no Exif segment, its metadata may have been stripped, or it may contain only unsupported proprietary fields. The absence of displayed rows is not proof that the image has never had metadata attached.
Camera, Capture, and Location Fields
EXIF groups related tags into directories, but the viewer turns those records into plain-language rows. Here is what the most useful groups mean in practical terms.
| Metadata group | Recognized fields | What the values describe |
|---|---|---|
| Camera | Make and model | The camera maker and model recorded by the file |
| Display | Orientation | How the stored image is intended to be displayed |
| Software | Software | Software recorded as writing or modifying the metadata |
| Dates | Original and modified capture times | Timestamps stored in the file, which may not reflect the present reality |
| Exposure | Exposure time, f-number, and ISO | Recorded capture settings |
| Optics | Focal length and lens model | Lens information and focal-length data stored by the camera |
| Dimensions | Pixel width and height | The stored image’s pixel dimensions |
| Location | GPS latitude and longitude | Coordinates embedded in the Exif GPS directory |
These fields are useful for checking what the file claims, but the viewer does not independently verify them. For example, an orientation label can help explain how the image should appear, yet it does not prove when or where the picture was captured. Likewise, the camera model, lens name, and exposure settings may have been copied from another file.
GPS Coordinates Need a Privacy Check
When standard EXIF GPS latitude, longitude, and hemisphere references are present, the viewer converts the stored degrees, minutes, and seconds into signed decimal degrees. That makes the location easier to recognize, but it can also expose a precise shooting location to anyone who receives the original file or a metadata report.
Review the GPS rows before posting the photo, sending the original file, or sharing a technical report. Also check whether the audience needs the coordinate at all. A location field is metadata embedded in the image, but it can still be sensitive even when it is stale, edited, or no longer exactly reflects where the photograph was taken.
Format and Privacy Boundaries
The viewer reads JPEG Exif, not every kind of image metadata. It does not claim full XMP, IPTC, HEIC, PNG, WebP, RAW, video, or proprietary maker-note coverage. Unsupported proprietary maker notes are intentionally ignored rather than guessed. If those records matter, use a full desktop metadata tool instead.
Within JPEG Exif, the reader supports little-endian and big-endian TIFF byte order, inline and offset values, ASCII, SHORT, LONG, RATIONAL, signed values, the Exif subdirectory, and the GPS subdirectory. Safety checks reject malformed segment lengths, excessive directory entries, unsupported or oversized field counts, and offsets that point outside the selected file. The parser stops at the first valid Exif APP1 segment.
Privacy comes from the processing location: the JPEG bytes are read and parsed in the current browser tab rather than sent to a server. That protects the selected file from an upload workflow, but it does not make embedded GPS data harmless. Treat the displayed location as information that needs an intentional sharing decision.
Metadata Is a Clue, Not Proof
EXIF data can be missing, stale, edited, copied, or removed by messaging and social platforms. It is therefore not proof of authorship, ownership, capture time, location, or authenticity. A detailed camera record can still travel with a picture that did not originate from that camera, and an absent date does not disprove when an image was created.
Use the viewer to inspect and understand the metadata stored in a particular JPEG. For stronger technical analysis, retain the original file and investigate with a broader tool rather than treating one browser table as a forensic conclusion.
Use a Desktop Tool for Deeper Analysis
Move to a maintained desktop metadata tool such as ExifTool when you need unsupported formats, proprietary maker notes, complete metadata inventories, batch export, or forensic evidence. Preserve the original file and do not rely on a converted or re-saved copy, because an export process can change which metadata remains.
The browser viewer follows the CIPA Exif 2.3 specification and cross-checks its recognized tag identifiers and types against ExifTool’s official EXIF tag table. Those standards support accurate field interpretation, but they do not turn editable metadata into proof that a photograph is authentic.
