PNG Metadata Viewer
Upload a PNG to inspect EXIF/XMP blocks, GPS tags, and text chunks (tEXt/iTXt/zTXt) while keeping pixels untouched.

Why view PNG metadata?
Checking PNG metadata helps you protect privacy, verify authenticity, and understand how the file was created.
Protect privacy
Catch GPS trails, device IDs, and captions in your PNG before posting or handing off.
Verify authenticity
Check capture time, camera/lens settings, and export software to spot edits in your PNG.
Prep delivery
See color profiles, dimensions, and orientation so PNG exports look correct on every screen.
Preview the report layout
See how we surface EXIF, PDF, and video metadata before you upload your own file.
Example Metadata Report
After uploading, you'll get a detailed breakdown of your file's hidden data, similar to the example below.

Our secure process
We show you exactly what happens when you upload a file, so you know where your data goes and what stays untouched.
Upload over HTTPS
Pick or drop your PNG. Transfers are secure.
Parse metadata only
We read headers and metadata blocks; the file content is not changed or recompressed.
Highlight key signals
We group timestamps, authorship, location, and technical fields so you can spot what matters quickly.
Display readable results
You see structured metadata grouped by sections for fast review with no downloads required.
Delete temporary copy
The transient server copy is purged right after processing completes.

What PNG metadata can you view?
Here are the fields you can inspect before you share or archive the file. Use them to verify provenance, quality, and privacy.
- EXIF/XMP blocks and GPS (when present)
- tEXt/iTXt/zTXt chunks for captions and comments
- ICC profiles, bit depth, and transparency/orientation details
What metadata lives inside a PNG
PNG was designed in 1996 as a patent-free replacement for GIF, and its metadata story reflects that era: the spec defines three text-chunk types — tEXt (Latin-1), zTXt (compressed), and iTXt (UTF-8 with optional language tag) — that carry free-form key/value pairs like Software, Author, Copyright, Description, and Comment. Modern editors and phone screenshots rarely populate these, but screenshots from macOS, Photoshop exports, and scientific imaging tools often do, which is why an old PNG can still leak a machine name, render date, or keyword it was never meant to share.
On top of the native text chunks, most toolchains now piggy-back EXIF and XMP inside the eXIf or iTXt:XMP chunks. That is how a PNG can end up with GPS coordinates, camera make/model, lens focal length, and editing history — the same fields you would expect from a JPEG. You will also see ICC profiles (iCCP), gamma (gAMA), chromaticity (cHRM), and sRGB rendering intent (sRGB) chunks, which govern how the image should be color-managed on the display or printer.
Because PNG is lossless, every chunk sits next to the pixel data without touching it. The viewer walks the chunk list, decodes each one, and shows what is present — a transparent, read-only audit trail of what your PNG will reveal when it leaves your machine.
PNG metadata FAQs
Do screenshots store metadata inside the PNG?
They can. macOS screenshots embed a tEXt chunk with `Software` and sometimes a capture-source hint. Windows Snipping Tool and most mobile screenshots are cleaner but may still carry a sRGB/pHYs chunk that fingerprints the tool.
Can a PNG contain GPS coordinates?
Yes, if the file was exported from a phone or camera pipeline that wrote an eXIf chunk or embedded EXIF inside an iTXt:XMP block. Standard browser-saved PNGs do not carry GPS, but Lightroom, Photoshop, and many Android share-sheets do.
What is the difference between tEXt, zTXt, and iTXt chunks?
tEXt is plain Latin-1 key/value; zTXt is the same but zlib-compressed for large comments; iTXt is UTF-8 and supports a language tag and optional compression. We decode all three and show their contents verbatim.
Does the viewer strip or change the PNG?
No. We parse chunks sequentially and hand back the original file untouched. If you want a cleaned copy, use the PNG metadata remover — this tool is read-only.
Why does my PNG show an ICC profile I did not set?
Most editors inject a default ICC (usually sRGB IEC61966-2.1) on export even when you do not choose one, which is why the profile field is rarely empty on modern PNGs.
