Convert an Image into a Base64 Data URI String
Encode a PNG, JPG, WebP or SVG as a complete base64 data URI ready to paste into CSS, HTML or JSON. Bytes unchanged, encoded in your browser.

- Produces the complete data URI with the correct MIME prefix, so it pastes straight into src or url() without editing
- The original bytes are encoded unchanged — no re-compression, no resizing, no quality change
- One click copies the whole string to the clipboard, or saves it as a .txt file for long output
- Shows the character count, which is the number that tells you whether inlining is sensible
Base64 re-expresses a file's binary bytes using sixty-four printable characters, letting an image be embedded directly inside CSS, HTML or JSON as a data URI instead of being fetched as a separate file.

How to Use the Free Online Image to Base64 Converter Studio in 4 Steps
Simple 4-step walkthrough for fast, secure processing
Shrink the image first if it is large
Encoding adds a third to the size, so use the Resize and Compress Image tools before encoding anything you intend to inline.
Drop the image in
PNG, JPG, WebP and SVG are accepted, and the file is read and encoded inside this tab.
Check the character count
The length is shown alongside the output. A few thousand characters is comfortable to inline; tens of thousands is a sign to link the file instead.
Copy or download the string
Copy the whole data URI to the clipboard, or save it as a text file when the output is too long to handle comfortably.
