Html Email Embed Image Base64

Html Email Embed Image Base64 – You are trying to use base64 images in your email signature. Unfortunately, you find that these images are corrupted because your email client cannot display (render) them. Additionally, when adding a signature using the Signature Web Add-in for Outlook (either automatically or manually), you may receive the following error message:

Base64 encoding allows you to convert various types of data (including images) into a human-readable string. The string can be embedded directly into your code (eg the HTML code of your signature). The main advantage of such an approach is that there is no need to take data from external sources because it is already there – in the code. However, this can be achieved using embedded images.

Basically, base64 encoded images are technically supported in all signature modes (you can manually include them in your HTML), however they may cause unexpected errors or behavior.

Why Optimizing Images With Base64 Is Almost Always A Bad Idea

Support for Base64 images varies by email client, meaning some clients cannot display them (like Gmail on the web).

In short, it is better to embed your images when designing a template in the editor available in email signatures for Office 365 – this method has proven itself on different platforms and a range of different emails. Clients have proven. To embed a traditional PNG or JPEG (JPG) image in your signature template, click the Image button on the editor ribbon, select the Embedded Image option, and select your image file (Figure 1.).

By using embedded images this way, you avoid both problems associated with using base64 encoding, and your recipients no longer have to click the “Download images” (or similar) button. 20 years ago we all had a very slow internet connection. Some of us even had traffic controlled plans. For this reason, many have disabled the display of images in their browser. Developers need to check how web pages look without images. Do you really miss those days? There is no reason for that, but we still have this problem in the email world.

Embedded Images In Html Email

About 25% of viewers are unlikely to see images in their emails. There are three main reasons for this: to save traffic on mobile devices, to prevent tracking of user behavior (when images are in the cloud), and some large companies prevent their employees from downloading images from external servers. There is a solution for the last two reasons using embedded images.

We usually upload the required image files to a public web server. Links to these files are then used in our code. For example:

It is very difficult without special equipment. If you are developing HTML code on your computer, all image files should be stored in a local folder. Also, you should use local links for your files in code, e.g

Embed Html Mail Images

There are two basic approaches to attaching images to email messages: include and embed. When including, everything is straightforward: you add it as a separate file that does not affect the HTML structure. In this case, your recipient will receive the attached image, unaltered and uncompressed. The only thing you need to worry about is the maximum email size limit. Even if your email client/service can send a large attachment, that doesn’t mean your recipient will receive it. If you’re not sure what email client the other side is using, stick to the smallest range possible. Overall, email services are pushing size limits: Outlook desktop allows sending up to 20MB, while other popular email clients allow 25MB and more.

When you create transactional emails, whether it’s an order confirmation, an account notification, or an automatically generated payment receipt, you’ll most likely add some design elements or at least your company logo. In this case, you need to embed an image in the email, and this is where it gets complicated. By embedding we also attach an image, but now it is an integral part of the HTML message body. Apart from the size of the image, you must now decide where to host it and how to encode it, because no one can guarantee that it will be displayed correctly.

Depending on the behavior of email clients, you can choose between three main techniques for embedding images in emails.

MIME (Multipurpose Internet Mail Extensions) is an Internet standard developed for SMTP that allows multiple content types (HTML and text) to be sent in a single message body and supports non-text attachments such as images.

This means that your message must contain at least two parts, HTML and plain text, separated by defined boundaries.

Embedding Images In Emails: Good Or Bad Thing?

To embed an image, attach it, set its CID (Content ID) and reference it in the message body with a standard HTML tag:

This method of working with images has been used for a long time. However, since it is an attachment, it affects the size of the email message. The larger the email size, the longer the loading time, which can be very annoying for your recipient. Several things to note:

Another way to display an image in the message body is to include a base64 image in the HTML. It also refers to the MIME standard, but don’t worry too much about that here. Base64 is a group of similar binary-to-text encoding schemes. If you want to know more about this, check out Wikipedia as it has a comprehensive article on the subject.

To include an image in your email, you need to base64 encode the image file: use one of several encoding services, and then include the base64 numbers in the HTML code, like this:

Be prepared to see very long code for the image as each Base64 digit represents 6 bits of data. This long image path also increases the overall size of the HTML message. Do not use it for large images.
