# Image Info & EXIF Viewer — Check image size, dimensions and EXIF on Mac

See size, dimensions, format and DPI, plus the camera, date and location hidden in a photo. Part of OneMacTools, 151 private tools in one native Mac app (macOS 26 or later); category: Images. Runs on your Mac; nothing is uploaded.

Drop images to see their real format, pixel size, aspect ratio, file size, DPI and print size, colour profile, camera and lens, exposure settings, date taken and location with a map link. Set limits — maximum or minimum KB, exact pixels — and every file gets a clear pass or fail before you upload it anywhere.

## How to use it
1. **Drop your images.** Add one image or many. Each gets its own block in the report.
2. **Add limits if you're uploading somewhere.** Type the form's rules in the right-hand panel: a maximum KB, a minimum KB, or an exact pixel size.
3. **Click Inspect.** The report appears in the app straight away: pixels, aspect ratio, file size, format, DPI, colour profile, camera and location where present.
4. **Read the checks.** With limits set, each image gets a tick or a cross for each rule, and the summary says how many don't meet them.
5. **Save the report if you need it.** Turn on “Also save the report as a file” to keep it as a text file in a dated folder in Downloads › OneMacTools.

## Options
- **Check: no bigger than (KB):** Optional. Type the largest file size allowed, such as 50, and each image is marked as under or over it. You can also type values like 1 MB.
- **Check: at least (KB):** Optional. The smallest file size allowed, such as 20. Many exam and government portals reject files below a minimum.
- **Check: exact size (px):** Optional. The exact width and height required, such as 200 x 230. Each image is marked as matching or not.
- **Also save the report as a file:** Off by default. Saves the full report as a text file as well as showing it in the app.

## Tips
- Check before you upload. Typing an exam or job portal's KB and pixel limits tells you in seconds which files will be rejected.
- Look at the print size line before printing. If an image has a DPI set, the report shows how big it prints in centimetres at that DPI.
- Check where a photo was taken before you share it. If a location line appears, anyone with the original file can see it too.
- Width and height are reported the way the photo displays, with the camera's rotation already applied, so portrait phone photos read as portrait.
- If a photo shows no camera details, it was probably a screenshot or passed through a messaging app that removed them.

## Questions
**How do I check a photo's size and dimensions before uploading?**
Drop it on Image Info & EXIF Viewer to see the pixels, KB, format and DPI. Type your form's limits, like at most 50 KB or exactly 200 × 230 px, and each file gets a pass or fail.

**How do I see where a photo was taken on a Mac?**
Drop it in and click Inspect. If the photo has location data, the report shows the coordinates, the altitude if recorded, and an Apple Maps link.

**How do I find out which camera or phone took a photo?**
The report lists the camera make and model, the lens, and the settings used: shutter speed, aperture, ISO and focal length, along with the date it was taken.

**Why is there no camera or location data?**
Screenshots never have any, and many apps, especially messaging apps, strip it when you share. A missing result just means there was nothing to read.

**How big will my photo print?**
If the file has a DPI value, the report shows the print size in centimetres at that DPI. For a sharp print, 300 DPI is a common target.

**How do I remove the location instead?**
Use Remove Metadata, which saves clean copies without the location, camera and other hidden details.
