What does this tool support?

Choose PNG, JPEG, GIF or WebP up to 5 MB. File signature and type must agree. Convert starts locally; no image is rendered. Output is a text data address up to 7 MB. Original metadata remains in the bytes: copying this result also copies any embedded metadata. The signature check is not a complete image integrity check.

Is my content saved or uploaded?

No. Only your non-sensitive settings are remembered. Input, output, image data and filenames stay out of storage and statistics.

What happens with a large result?

The displayed text is a limited preview above 200,000 characters. Download retains the complete result; copying is limited to 2 MB. A protective limit produces an error, never a silently shortened download.

Runs locally in your browser

Images: up to 5 MB. Output: up to 7 MB. Metadata stays in the encoded bytes. Files stay in your browser.

Guide

Turn a local image into a Base64 data address that contains the image bytes as text. Select the image and choose Convert to generate the result for copying or download.

Choose an image
Choose Example image or Open file. Files remain in this browser.
Choose the options
Use the controls above the fields. The question-mark buttons explain unfamiliar choices.
Read and keep the result
Choose Convert or Generate, then read Output. Download keeps the full result.

On mobile, choose Output to read the result. Clear removes both fields.

Image conversion

File types: PNG, JPEG, GIF or WebP, up to 5 MB (5,000,000 bytes). The detected file type must match its signature.
Convert: explicitly start local conversion. The image is not rendered or uploaded.
Output: a text data address, up to 7 MB (7,000,000 bytes), which contains the original file bytes.
Metadata: embedded information remains in the result. Sharing it also shares that metadata; the signature check is not a full image integrity check.

Shortcuts

Ctrl / Cmd + Enter — Run selected action
Ctrl / Cmd + Shift + C — Copy output
Ctrl / Cmd + S — Download output
? — Show shortcuts outside text fields

Shortcuts work while focus is in the workspace. Copy and download need valid output.
