Base64 to Image Converter

Paste your Base64 string into the input field on this page and the image preview appears instantly. You can download the decoded image or copy it as raw Base64, a data URI, an HTML img tag, or a CSS background property. No software installation is required.

Visit base64toimagefree.com — a free base64 to image online converter that runs entirely in your browser. Paste your encoded string, see a live preview, and download or copy the result. Your data never leaves your device because all processing happens client-side.

Base64 text is a text representation of binary image data. Paste the text (with or without the data:image/png;base64, prefix) into our decoder. The tool converts the Base64 text back into a viewable image automatically. It supports PNG, JPEG, GIF, WebP, SVG, AVIF, and ICO formats.

Yes. Base64 encoding is fully reversible — it is not encryption. Decoding Base64 restores the original binary data exactly. Our Base64 to Image tool reverses the encoding by decoding the string and rendering the original image file. Format conversion (e.g. PNG to JPEG) is a separate optional step on our format converter page.

Base64 is an encoding scheme, not encryption — so "decrypting" Base64 actually means decoding it. Paste the Base64 string into our decoder to convert it back to its original image. If the data was encrypted before encoding (e.g. with AES), you would need the original encryption key — standard Base64 decoding alone will not recover encrypted content.

Paste the Base64 string or data URI into the Base64 to Image page to see a live preview with MIME type, dimensions, and file size. You can also view Base64 images by setting an HTML <img src="data:image/png;base64,..."> tag, or by pasting a data URI directly into your browser address bar if it includes the full data:image/... prefix.

A Base64 image is binary image data encoded as a text string using Base64 encoding. It is commonly used in JSON APIs, HTML emails, CSS, and data URIs (data:image/png;base64,...). Base64 is encoding, not encryption — it can be fully decoded back to the original image file.

Raw Base64 is just the encoded string. A data URI adds a prefix with the MIME type, like data:image/jpeg;base64,/9j/4AAQ.... Our tool accepts both formats. Use our data URI to image converter if you specifically work with data:image/... strings.

Common causes: invalid characters in the string, missing or incorrect data URI prefix, truncated/corrupted data, or wrong MIME type. Ensure the string contains only valid Base64 characters (A–Z, a–z, 0–9, +, /, =). Paste the full string and check for extra whitespace or line breaks. Our decoder shows a clear error if the input is invalid.

Our tool supports files up to 10 MB for image-to-Base64 encoding. For Base64-to-image decoding, the decoded image must also be within 10 MB. Larger strings may slow down your browser because all processing happens client-side on your device.

In JavaScript, set an image source to a data URI: img.src = "data:image/png;base64," + base64String. To download, convert Base64 to a Blob using atob() and Uint8Array, then create an object URL. Our online tool does this instantly without writing code — paste, preview, and download.

Paste your Base64 string into our Base64 to PNG converter, select PNG as the output format, and click Convert. You can also decode on the base64 to image page and download directly if the source is already PNG.
