Does this Scrub PNG Data work completely offline without internet?

Yes. Once the page is loaded, all processing runs locally on your device in WebAssembly and HTML5 Canvas. You can disconnect from the internet or use airplane mode and continue converting safely.

Are my files uploaded to a remote server or cloud?

No. 0mod operates on a zero-upload architecture. Your files never leave your local device, making it safe for confidential, legal, healthcare, or personal documents.

Is there any file limit, queue, or paid subscription?

No. Because conversion runs on your device hardware rather than metered cloud servers, there are no artificial file caps, queues, or subscriptions.

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

How It Works

Upload PNG: Select your .png file.
Process: The tool parses the PNG structure and regenerates a new file containing only the critical image data.
Download: Save the clean PNG.

100% Private

This tool runs locally in your browser. Your PNG files are never uploaded to any server, ensuring total privacy for your screenshots and designs.
