Base64 to Image
Decode raw Base64 or a data URL after validating the raster image signature.
Decode raw Base64 or a data URL after validating the raster image signature. Processing stays on your device and the original remains unchanged.
How OpenFileTools processes it
Local processing, explicit choices.
The source is validated and processed in this browser tab. Large format codecs are loaded only on the relevant page; no image bytes are uploaded.

Validate decoded bytes, not just a format selector
Paste a supported data URL or choose a declared format for raw Base64. The decoded PNG, JPG, WebP, GIF, or AVIF signature must match before preview or download; SVG and markup are rejected.
Questions, answered.
Can this decode SVG?
No. Active markup formats are intentionally rejected.
