Base64 to Image decodes Base64 strings and data:image URLs into downloadable PNG, JPG, WebP, GIF, or SVG files entirely in your browser—nothing is uploaded.
Base64 to Image is a free browser decoder that turns Base64 text or full data URLs (data:image/png;base64,…) into real image files you can preview and download. Paste from DevTools, APIs, Slack, or databases; the tool strips whitespace, detects MIME type from the prefix or magic bytes, and shows live metadata (format, size, dimensions).
Supports PNG, JPEG, GIF, WebP, SVG, BMP, ICO, TIFF, and AVIF. Strings under ~15 MB decode smoothly; larger payloads show warnings. Pair with Image to Base64 for encoding and Image Compressor if the decoded file is still too large for your form or CMS.
Concise answers for common searches — definitions, steps, and comparisons.
A data URL embeds an entire file in a single string: data:image/png;base64, followed by the Base64 payload. Browsers can render it directly in <img src="…"> without a separate HTTP request. This decoder accepts the full URI or only the Base64 portion after the comma.
Base64 maps every 3 bytes of binary data to 4 ASCII characters. That expansion is normal—it is not corruption. After decoding, the downloaded image matches the original binary size (minus padding).
Right-click an image in the Network or Elements panel and copy as data URI, then paste here. The tool detects PNG/JPEG/WebP from the prefix, previews instantly, and lets you download a normal file for editing or compression.
Paste the full string—including data:image/png;base64, if present—or only the characters after the comma. Use Paste from Clipboard or drag text or an image file onto the drop zone.
The preview updates as you type. Check detected format, estimated file size, width, height, and aspect ratio in the metadata panel before downloading.
Click Download Image to save PNG/JPG/WebP (or detected type), or copy as raw Base64, data URL, or bitmap to the clipboard for reuse in code or design tools.
Base64 is ~33% larger than binary. After download, use Image Compressor or Image Resizer if the file must meet a portal or email size limit.
Common real-world scenarios where this tool saves time.
Decode image fields returned as Base64 in REST or GraphQL responses to verify thumbnails, avatars, or receipt scans without writing a script.
Preview data:image URLs copied from Chrome DevTools, Storybook, or inline CSS before replacing them with hosted asset URLs.
Turn pasted Base64 snippets from Slack, Jira, or log files into viewable images for designers and QA.
Recover PNG/JPG files stored as Base64 columns in CMS exports, legacy configs, or email templates.
Step-by-step chains that connect related tools for common tasks.
| Input style | Example prefix | Format detection | When to use |
|---|---|---|---|
| Full data URL | data:image/png;base64, | From MIME in prefix | HTML img src, CSS, clipboard from DevTools |
| Raw Base64 only | iVBORw0KGgo… | Magic-byte signatures | API bodies, logs without prefix |
| Whitespace-wrapped | Line breaks in PEM-style blobs | Stripped automatically | Copied from multi-line configs |
| Tool | Direction | Typical source |
|---|---|---|
| Base64 to Image (this page) | Text → file | APIs, data URLs, logs |
| Image to Base64 | File → text | Embedding in HTML, CSS, JSON |
This tool accepts both formats—if decode fails, try including data:image/png;base64, or only the characters after the comma.
Paste only the Base64 or data URL value. Remove surrounding quotes, commas, or JSON keys like "image":.
Format is auto-detected; if unknown, PNG is used as a safe default. Check the metadata panel for the detected MIME type.

Yes. Paste the full data URL—including the data:image/…;base64, prefix—or only the Base64 payload after the comma. The decoder strips whitespace, detects the MIME type when possible, and shows a live preview before you download.
Yes, as long as the payload is valid Base64 (optionally wrapped in a data URL). Everything runs locally in your tab: nothing is uploaded, so clipboard snippets from DevTools “Copy image as data URI” or API docs are safe to decode here.
Base64 is an encoding scheme that converts binary data (like images) into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). It lets you embed images in HTML, JSON, or APIs as text. Decoding converts that text back into the original image file.
Yes. All conversion runs in your browser. Your Base64 data is never uploaded or sent to any server. Everything stays on your device.
PNG, JPEG, JPG, GIF, WebP, SVG, BMP, ICO, TIFF, and AVIF. If the format is not detected from the data URL, the tool still allows preview and defaults to PNG for download.
Yes. This tool automatically detects the image format and allows you to download it as PNG, JPG, WebP, or other supported formats.
Yes. Once the page is loaded, the tool runs entirely in your browser with no server calls. You can use it offline to decode Base64 strings and download images.
Yes. The tool detects Base64 strings even without the data URL prefix. It uses format detection from the data URL when present, or MIME signatures (e.g. PNG, JPEG, GIF) when the prefix is missing.
Base64 encoding increases file size by roughly 33% compared to the original binary image. This is normal. You may want to compress the image after downloading if you need a smaller file.
Base64 encoding increases size by about 33% because it uses 4 ASCII characters to represent 3 bytes of binary data.
Strings under about 15 MB decode without warnings. Between 15–40 MB a warning appears; above 40 MB decoding is blocked to protect browser memory.
All Base64 decoding runs in your browser. Strings and images are never uploaded to EverydayTools servers.
Format detection uses data URL prefixes and standard Base64 magic-byte signatures; output matches browser atob decoding.
