How to Convert Base64 to an Image Online
Base64 is a way of writing binary data — like an image — as plain text so it can live inside code, JSON or a data URI. This tool does the reverse: paste that text and it decodes it back into a real image you can see and save. It accepts a full data URI or just the raw Base64, detects the type, previews it, and lets you download the file — all in your browser, with nothing uploaded.
Paste the Base64
Drop in a full data:image/... URI or the raw Base64 string. It's decoded locally — nothing is uploaded.
Confirm the type
A data URI already knows its type; for raw Base64, pick PNG, JPG, WebP, GIF or SVG.
Preview & download
See the decoded image, then download it as a real file in the right format.
When to Use This
Recover an embedded image
Pull an image back out of CSS, HTML, JSON or an API response where it was stored as Base64.
Debug data URIs
Quickly check what a data:image string actually contains while developing or troubleshooting.
Save inline email images
Turn a Base64 image from an email or export into a normal file you can keep.
Extract from config or DB
Decode an image that was stored as a Base64 text field back into a usable file.
No tooling needed
A quick decode-and-download without opening a code editor or writing a script.
Private by design
Because it runs in your browser, the data you paste is never uploaded anywhere.
Frequently Asked Questions
How do I convert Base64 to an image for free?
Paste your Base64 string or data URI above, preview the decoded image, and press Download — free, no signup, no watermark.
Do I need the data:image prefix?
No. If you paste a full data URI the type is detected automatically; if you paste raw Base64, just pick the image type and it's added for you.
Which image types are supported?
PNG, JPG, WebP, GIF and SVG. For a data URI the type comes from the string; for raw Base64 you choose it.
Why doesn't my string decode?
It may be truncated, contain stray characters, or not actually be image data. Make sure you copied the whole Base64 string, including all of it after the comma in a data URI.
Is my pasted data uploaded anywhere?
No. The decoding happens entirely inside your browser, so nothing you paste leaves your device.
Is there a size limit?
There's no fixed limit, but extremely long strings use more memory. For very large images this still works, just give it a moment.
Can I convert an image back to Base64?
Yes — use our Image to Base64 tool for the reverse direction, to encode a file into a data URI.
Does it work on phones?
Yes, in any modern browser on Windows, Mac, Android or iPhone with nothing to install.
Is this Base64 to image tool really free?
Completely free, forever — no account, no watermark, no daily cap and no premium wall.
