Convert Base64 to Image — Free, Private, No Upload

Q: Do I need the data: prefix?

No. You can paste a full data URI (data:image/png;base64,...) or just the raw Base64. If there's no prefix, Latch detects the image type automatically from the decoded bytes.

Q: Why won't my Base64 decode?

Usually the string is incomplete or has stray characters. Make sure you copied the whole value. Data URIs must include the base64, marker. Latch trims whitespace and fixes padding automatically, but truncated data can't be recovered.

Q: What file do I get?

A real image file matching the detected type — image.png, image.jpg, image.svg and so on — saved straight to your device with one click.

Base64 to Image, explained

Base64 is a way of writing binary data — like an image — as plain text, so it can travel inside HTML, CSS, JSON or an API response. When you're handed one of these strings, you often need the actual picture back. This tool decodes it in your browser and hands you a real image file.

Paste either a full data URI (data:image/png;base64,…) or just the raw Base64. If the type isn't given, Latch reads the file's signature to work out whether it's a PNG, JPG, GIF, WebP, BMP, AVIF or SVG, and names the download accordingly. Whitespace and missing padding are fixed automatically.

Everything runs locally — the string never leaves your device, which matters when you're decoding data from private code or an internal API. Need to go the other way? Image to Base64 encodes a picture into a string.

Frequently asked

Is anything uploaded?

No. The Base64 is decoded entirely in your browser. Nothing is sent to a server — the tool even works with Wi-Fi switched off.

Do I need the data: prefix?

No. You can paste a full data URI (data:image/png;base64,…) or just the raw Base64. If there's no prefix, Latch detects the image type automatically from the decoded bytes.

Which image formats are supported?

PNG, JPG, GIF, WebP, BMP, AVIF and SVG. The type is read from the data URI if present, otherwise detected from the file's signature, and the download uses the matching extension.

Why won't my Base64 decode?
