Quick start

How to decode Base64 to an image

  1. Paste Base64 — use a full data:image/…;base64,… URL or raw Base64 that contains image bytes.

  2. Convert — click Convert. The tool checks that the data contains a supported image and loads a preview only when it does.

  3. Download or copy — save the image file, or copy the normalized data URL for reuse.

Format notes

Valid Base64 is not always an image

Any text can be Base64-encoded. This page only accepts payloads whose decoded bytes match a supported image format (PNG, JPEG, GIF, WebP, BMP, SVG, or ICO).

A complete data URL already includes the MIME type. Raw Base64 is fine too—we detect the format from file signatures when the prefix is missing.

If conversion succeeds, you will see format, dimensions, and size. Download as Original to keep the decoded file, or pick PNG / JPEG / WebP to re-encode. Invalid input shows an inline error and clears any previous result.

Editing the input clears the previous preview and disables Download so you never save a stale file by mistake.

Decoding runs in your browser—Base64 is not sent to ConversionTab servers for this tool.

Short answers about invalid input, formats, downloads, and privacy.

Valid Base64 for plain text (for example aGVsbG8= for “hello”) is not an image. Paste image data or a data:image/… URL. Use the Base64 Decoder for text.

Decode accepts PNG, JPEG, GIF, WebP, BMP, SVG, and ICO. Download as Original keeps that format, or choose PNG, JPEG, or WebP to re-encode before saving.

Yes. Paste raw Base64; we detect the image type from the decoded bytes and build a proper data URL for preview and download.

The preview, Download, and Copy actions clear immediately so you cannot download the previous image after changing the text.

No. Decoding and preview run in your browser. Download the image to your device when you are ready.
