Scrub PNG Data - Remove Metadata & Chunks
Clean your PNG images by removing hidden metadata, textual information, and auxiliary chunks. Ensure your graphics and screenshots are private before sharing.
Do PNGs Have Metadata?
Yes. While PNGs don't use the same EXIF structure as JPEGs by default, they use "chunks" to store auxiliary data. This can include:
- tEXt / zTXt / iTXt Chunks: These can store free-form text like the author's name, copyright notices, software used (e.g., "Adobe ImageReady"), and creation time.
- eXIf Chunk: Newer PNG standards allow embedding full EXIF data (including GPS) directly into PNG files.
- pHYs Chunk: Physical pixel dimensions (DPI).
- tIME Chunk: The last time the image was modified.
Why Scrub PNGs?
1. Remove Software Fingerprints
Screenshots or exported graphics often contain the name of the software used to create them. Scrubbing removes these "fingerprints."
2. Protect Copyright & Privacy
If you are sharing a draft or a meme, you might not want your name or creation date embedded in the file.
3. Optimize for Web
Removing unnecessary chunks (ancillary chunks) can slightly reduce the file size, making your website load faster.
Example: PNG Chunk Removal
| Chunk Type | Description | Status After Scrubbing |
|---|---|---|
IHDR | Image Header (Critical) | Kept (Required) |
IDAT | Image Data (Critical) | Kept (Required) |
tEXt | Textual Data (Software, Author) | Removed |
zTXt | Compressed Text Data | Removed |
eXIf | Embedded EXIF (GPS, Camera) | Removed |
tIME | Modification Time | Removed |
