Read image file bytes locally in the browser and convert them into raw Base64 text or a full data URL.
The image bytes were converted into Base64 text locally in your browser.
The browser reads the selected image file with FileReader and returns either the raw Base64 payload or the full data URL string.
This is an encoding step, not a visual transform, so the original image bytes are preserved in the encoded output.
No. Base64 encoding preserves the original bytes. MIME type metadata is included only when you keep the full data URL form.
Different destinations expect different formats, so the tool supports both common outputs.
Yes. Any regular image format the browser can read as a file should work.
Yes. High-resolution images can create very large text strings that are harder to copy and render.
Base64 is convenient for embeds and transport, but it is not efficient for very large assets.
Because the tool only reads the file, there is no lossy conversion or canvas re-encoding step here.
The MIME type stays important when you later use the encoded string in another context.
