Free online MSG to WEBP converter

Source format: MSG

MSG is a Microsoft Outlook message file format used to store a single email message, including the subject, sender, recipients, body, attachments, and sometimes calendar or task-related metadata. It is commonly created and used in Microsoft Outlook and in email archiving or e-discovery workflows. MSG files are useful when you need to preserve an individual email exactly as it was received or sent.

Target format: WEBP

WEBP is a modern image format developed by Google. It supports both lossy and lossless compression, plus transparency and animation. WEBP is widely used on the web because it often produces smaller files than JPEG or PNG while keeping good visual quality. It is a strong choice for screenshots, graphics, and web publishing.

How to perform the conversion

Converting MSG to WEBP is not a direct format-to-format conversion in the usual sense, because MSG is an email container and WEBP is an image format. In practice, you first need to extract or render the visible content of the email as an image, then save that image as WEBP.

1. Open the .msg file in Microsoft Outlook or another MSG-compatible viewer.
2. If the email contains the content you want to preserve, display it on screen at the desired zoom level.
3. Capture the message as an image using a screenshot tool or export the email content to an image-capable workflow.
4. Open the captured image in an editor such as Paint, GIMP, or Photoshop.
5. Save or export the image as WEBP. In many editors this is found under File → Export As or File → Save As.
6. If you need a batch workflow, first convert or render the MSG files to images, then convert those images to WEBP.

Notes on quality, compatibility, or limitations

This conversion has an important limitation: MSG is not an image format, so the result in WEBP will only be a visual snapshot of the email, not a fully editable email file. Any attachments, message headers, and hidden metadata will usually be lost unless you preserve them separately.

Image quality depends on how the email is rendered and captured. Text may become blurry if the screenshot is low resolution, while a higher-resolution capture will produce a clearer WEBP file. If the email is long, you may need multiple screenshots or a scrolling capture tool, because a single image may not contain the entire message.

For archiving or legal purposes, keep the original .msg file alongside the WEBP image. Use WEBP when you need a compact visual representation of the email, not when you need the email itself.
