Image Metadata Viewer — EXIF, Dimensions & Alpha
Drop one image or many to see dimensions, megapixels, file size, alpha, and full EXIF metadata — including camera make and model, capture date, exposure, and GPS coordinates where present. Everything runs in your browser, so you can audit a photo for hidden location data before posting it — without uploading it anywhere.

Multiple files allowed
What you'll see per file
- file / type / size — filename, MIME type, byte size.
- dimensions / megapixels — width × height in pixels and total MP.
- alpha — yes / no (based on a pixel scan of the corners). Yes = the PNG carries transparency.
- EXIF (when present, JPG sources) — camera make & model, lens, capture timestamp, exposure, aperture, ISO, focal length, GPS coordinates, orientation, software.
Common reasons to inspect
- Pre-share privacy audit. Phone photos often embed GPS coordinates and your device serial. Check before posting publicly.
- Asset audit. Folder of mixed sources — see dimensions / alpha at a glance to plan a batch convert.
- Debug a converter. Verify format / dimensions / alpha before shipping.
- Photography QA. Verify EXIF survived an export pipeline (or that it didn't, before sharing).
How to strip EXIF
If the inspector shows GPS or device info you don't want shared:
- Convert via PNG → JPG or JPG → PNG — the re-encoded output has no EXIF.
- Or run through Compress at quality 1.0 — same result.
- Macs: right-click → Get Info → remove individual EXIF fields.
FAQ
How do I check an image's dimensions?
Drop the file and the card shows its exact width × height in pixels and total megapixels — for one image or a whole batch at once. Nothing is uploaded and it works offline.
How do I remove GPS / EXIF location from a photo?
Re-encode it: run the photo through PNG → JPG, JPG → PNG, or Compress at quality 1.0 — the output carries no EXIF, so the GPS and device data are gone.
Why don't I see EXIF on my PNG?
PNG doesn't typically carry EXIF — it uses different metadata containers (tEXt / iTXt chunks) that this reader doesn't expose. EXIF is normally only present in JPG (and some WebP).
Alpha says "yes" but image looks fully opaque?
The PNG has an alpha channel but no transparent pixels — common when a source was saved as RGBA but the content is fully opaque. View in PNG viewer to confirm visually.
Does this work for HEIC or RAW?
Only what your browser can decode. HEIC has partial Safari support; RAW formats (CR2, NEF, ARW) typically don't open here.
Part of: Redact an image before sharing it
Pixelating a face is reversible in principle; a solid block is not. For anything that matters, use the block.
- 1 Pixelate Pixelate, blur or drop a solid block over a region
- 2 Remove metadata Strip GPS, camera serial and editing history
- 3 Chunk viewer See every chunk still in the file, byte by byte
- 4 Inspector Confirm the metadata has really gone
Part of: Work out what is wrong with a PNG
Start with the validator. It tells you whether the file is broken or merely unexpected, which are different problems.
- 1 PNG validator Signature, chunk order and CRCs, checked
- 2 Chunk viewer Every chunk in the file and what it holds
- 3 Inspector Dimensions, bit depth, colour type, metadata
- 4 Color count Whether it is really as complex as it looks
- 5 Dimensions What the pixels actually measure
