Frequently asked questions
What is a Base64 image?
A Base64 image is a binary image file encoded as ASCII text. It is often embedded directly in HTML, CSS, or JSON as a Data URL (e.g. data:image/png;base64,...) to avoid separate file requests. This tool decodes it back to a viewable image.
Do I need the 'data:image/...;base64,' prefix?
No. This tool accepts both raw Base64 strings and full Data URLs. If you paste a raw string, the format is auto-detected from the binary signature (JPEG, PNG, GIF, WebP, etc.).
What image formats are supported?
PNG, JPEG, GIF, WebP, SVG, BMP, and ICO. The format is auto-detected from the Base64 header bytes so you do not need to specify it manually.
Is my data sent to a server?
No. Everything happens in your browser using the Web APIs. Your Base64 string never leaves your device.
