Image Obfuscation

Click to upload, or drag an image here

PNG / JPG / GIF (first frame) · Very large images are scaled down for smoothness

Image obfuscation rearranges pixels along a space-filling curve (Gilbert curve), turning the picture into meaningless colorful noise;
An obfuscated image keeps its colors even after compression and de-obfuscates normally (near-lossless under light compression);
Obfuscate: turn a normal image into a scrambled one; De-obfuscate: restore a scrambled image (must have been obfuscated by this site);
Restore: go back to the originally uploaded image (valid for this page session only);
Downloads are JPG at 95% quality;
Unlike steganography: obfuscation hides no files, it just makes the picture unreadable — great for "anti-spoiler" or "anti-scraper" posts;
For study and research only. Do not use for unlawful purposes.

Not a filter — every pixel is moved to a new position along the Gilbert curve. Impossible to reverse by eye.

A shuffled image survives WeChat/QQ-style compression and still de-obfuscates with colors intact.

All computation happens in your browser. Nothing is uploaded — works offline.
