Normalized data URL
Data URL preview without upload
The viewer accepts complete image data URLs or raw Base64. Raw input is treated as PNG by default for preview purposes.
Which image formats can be previewed?
Complete data URLs keep their declared MIME type. Raw Base64 input is previewed as PNG.
Is the image sent anywhere?
No. The preview uses the pasted string directly in the browser.
