Frequently Asked Questions

What does Img to CSS do?

Img to CSS converts images to HTML. It does this by creating an HTML table with colored cells. An image converted by Img to CSS will not be blocked by email clients and looks exactly like an ordinary image. We've created a gallery of screenshots so that you can see how our images display in different email clients.

Why aren't the converted images blocked by email clients?

Email clients look for "img" tags when they decide what to block. Img to CSS's method of creating images does not require an "img" tag, so email clients don't notice that there is an image.

How can I get more conversions?

If you have an account, you can buy more conversions here: buy conversions, or you can start a subscription for unlimited conversions.

Any Notes on Use?

The size of the resulting css/html file increases as the size of the image increases. For use in emails, only convert small images like icons and logos. Large images may be clipped by the email provider.

Transparency is also not supported by most email clients, so if you convert transparent PNGs, be sure to specify a background color.

Isn't this tool a spammer's dream?

We don't think that spammers will use this tool. Images converted by Img to CSS are larger than ordinary images, which means that they cost slightly more money to send. Spammers have a very low conversion rate, so they have to send massive amounts of emails to get a single sale. The added costs of sending images, though small for ordinary users, are amplified by the spammer's shotgun strategy. This should be enough to deter them from using the tool.

I can't log in to the site.

Cookies must be enabled to log in. We use the cookies to store things like your username, api key, and account type. This reduces the number of database queries that we have to make, which reduces costs.

Why isn't the conversion counter on the top left hand corner up to date?

We don't subtract the conversion until we're sure that the image converted correctly. This means that we have to send the response before the count can be updated. Once you navigate to a new page on the site, the count will be correct.

I see something like "<table cellpadding=0 ..." when I email an image.

In order to send html/css images, you must be able to edit the html. Most web clients don't offer this feature. You'll have to use a full-featured desktop client or a third-party service like MailChimp.

What are the downsides to using Img to CSS

Images converted by Img to CSS are larger than ordinary images. You have to be careful to keep the size of the email below 100kb or else gmail may clip the message. Also, if an image is forwarded from Outlook, it may not display in other clients. This is because Outlook changes the html when it displays the email, but does not change it back when it resends the email. Lastly, if an image is sent by Thunderbird, it will not display correctly in the "compose message" pane. It does display correctly once the email sent, but Thunderbird adds html that increases the size of the email.
