Free online JPG to HTM converter

A legacy web editor, publishing system, or hosting environment may require an .htm page instead of a standalone image. The conversion creates an HTML document that displays the JPG; it does not turn JPEG image data into HTML code.

What the JPG format is

JPG, also written JPEG, is a raster image format designed mainly for photographs and other images with continuous color. Lossy compression keeps files small but can remove fine detail and create block or ringing artifacts, especially after repeated editing and saving.

Digital cameras, smartphones, scanners, image editors, and screen-capture tools commonly create JPG files. Web browsers and applications such as Adobe Photoshop, GIMP, Affinity Photo, and Microsoft Photos can open them. JPG supports millions of colors but does not support transparency; images with transparent areas generally require PNG or WebP.

What the HTM format is

HTM is the three-letter filename extension commonly used for an HTML web page. An HTM file is a plain-text document containing markup such as <html>, <head>, and <body>, along with text and references to images, stylesheets, scripts, and other resources.

.htm and .html normally represent the same HTML document type. The shorter extension remains useful for older web servers, editors, and publishing systems that expect three-character extensions. An HTM page can add a title, alternative text, captions, links, dimensions, and CSS around the original JPG without changing the image itself.

How to convert a JPG to HTM

The most reliable method is to create a small HTML page in a plain-text editor. A browser then loads the page and displays the JPG.

1. Put the JPG in a working folder and note its exact filename, including its extension and capitalization.
2. Open Notepad, VS Code, or another plain-text editor.
3. Create a file named photo.htm and enter the following code, replacing photo.jpg with the real image filename:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Photo</title>
</head>
<body>
  <img src="photo.jpg" alt="Description of the photo">
</body>
</html>

4. Save the file as plain text with the .htm extension. In Notepad, select Save as type → All files if necessary, and verify that Windows has not added .txt, producing photo.htm.txt.
5. Open photo.htm in a web browser. Keep photo.jpg in the same folder, because the relative path in src depends on it.

For a page hosted on a case-sensitive server, match the capitalization of the filename exactly. To control display size, add attributes such as width and height or use CSS; scaling a small JPG beyond its native dimensions can make it look soft.

Use the built-in online converter

You can also convert the file on 101convert.com for free without installing software.

1. Open the JPG-to-HTM converter on 101convert.com.
2. Upload the JPG and select HTM as the output format if a format selector is shown.
3. Start the conversion and download the resulting .htm file.
4. Open the downloaded page in a browser. If the generated HTML references the original JPG rather than storing it inside the page, keep the JPG beside the HTM file and preserve its filename.

Desktop editors can perform the same task. Microsoft Word can save a document containing an image through File → Save as → Web Page, but it may create additional folders, metadata, and presentation markup; a plain-text editor produces a smaller and more predictable page.

Quality and compatibility limits

Placing a JPG in an HTM file does not improve image quality, remove JPEG artifacts, or reduce the image's existing compression. The JPG remains a separate resource when the page uses src="photo.jpg"; moving only the HTM file creates a broken image.

For a self-contained page, the image can be converted to Base64 and placed in a data: URL, but this increases the HTML payload by roughly one third and makes the source harder to edit. A data URL also exposes the encoded image to anyone who can view the page source, so it is unsuitable for confidential content.

Use descriptive alt text for accessibility. Browsers generally render .htm and .html the same way, but a server can assign different routing or MIME settings to each extension. HTM is a page container, not a replacement for JPG: the browser still needs the image data, either as a linked file or embedded data.
