Is my image uploaded to a server?

No. All processing happens entirely in your browser using the FileReader API. Your image is never sent to any server.

What image formats are supported?

JPG, JPEG, and PNG files are supported. The tool reads the file's MIME type to embed it correctly.

Why is the HTML file larger than the original image?

Base64 encoding expands binary data by about 33% (a factor of 4/3). With the data-URI wrapper and HTML markup added, the resulting file ends up roughly 1.37x the size of the original image.

Can I open the downloaded HTML file without internet?

Yes. The HTML file is fully self-contained — the image data is embedded directly inside the file, so it works offline in any browser.

Is there a file size limit?

There is no enforced limit, but very large images (above ~20 MB) may slow down older browsers when generating the base64 string. For best performance, keep images under 10 MB.

Can I customize the HTML output?

You can set a custom document title before converting. The generated HTML is minimal and valid, so you can open it in a text editor to add further customizations after downloading.

Summary

This tool converts a JPG or PNG image into a self-contained HTML file by encoding the image as a base64 data URI and embedding it directly inside the HTML markup. Everything runs in your browser — no file is ever uploaded to a server. The resulting HTML file can be opened in any browser and displays the image without requiring any external files or network access.

How it works

Click "Choose Image" or drag and drop a JPG or PNG file onto the upload area.
A preview of your image appears immediately.
Optionally set a custom title for the HTML document.
Click "Convert to HTML" — the image is encoded to base64 and wrapped in a minimal HTML template.
Click "Download HTML" to save the self-contained HTML file to your device.

Use cases

Embed a photo into a standalone HTML file for offline viewing.
Package a diagram or chart as a portable HTML document to share with others.
