Frequently asked questions
Which input formats work?
The tool accepts data URLs or raw Base64 for PNG, JPG, WebP, and AVIF images.
Do I need the MIME type?
A data URL includes its MIME type. For raw Base64, the tool assumes PNG.
Why does decoding fail?
The text may be truncated, contain invalid Base64 characters, or describe an unsupported image format.
Is my text sent anywhere?
No. Decoding and preview happen locally in the browser.
Can I download the decoded file?
Yes. Once a valid image is decoded, a download link appears with the matching file extension.
