Your blog posts can carry images, video, and audio, and in most cases you simply paste a link and your store does the rest. This guide covers all three kinds of media, where each one goes on the post's edit page, and the few rules worth knowing.
Images
Every post can have a main image, and you have two ways to provide it. You can upload an image directly from your computer, or you can paste an external image URL if the picture already lives somewhere online (JPG, PNG, or WebP). If you supply both, the external URL takes priority. The main image is what appears at the top of the post and in most places the post is shown.
There is also a separate thumbnail image, used for the smaller previews in listings and related-post strips. Setting a dedicated thumbnail is optional — if you leave it blank, your store automatically falls back to the main image, so a post will never show up without a picture just because you skipped the thumbnail. Upload a purpose-made thumbnail only when you want the small preview to be cropped or composed differently from the full-size image.
Use WebP images whenever you can
The format you upload matters more than most people realise. WebP is a modern image format that shows the same picture at the same quality as a JPG or PNG, but in a much smaller file — often around a third smaller. Smaller files load faster, and that has real benefits for your store: pages appear quicker, visitors on phones and slower connections do not give up waiting, and Google rewards fast pages with better search rankings. Slow, heavy images are one of the most common reasons a site feels sluggish, so switching to WebP is one of the easiest speed wins you can make. Every modern browser displays WebP, so there is no downside for your visitors.
If you only have a JPG or PNG, it is worth the small extra step to convert it before uploading, because that one-time effort pays off on every single page view from then on.
How to convert a JPG or PNG to WebP
You do not need any special software — a free website does it in seconds. A good free tool is Squoosh (squoosh.app, made by Google): open it, drag your JPG or PNG in, choose WebP as the output format on the right, and download the result. Other free browser tools do the same job, including FreeConvert (freeconvert.com) and, if you have lots of images to do at once, batch converters such as toWebP.io.
Two quick tips while you are there. First, resize very large images down to a sensible width before converting — a blog image rarely needs to be wider than about 1500 pixels, and shrinking the dimensions saves even more weight than the format change alone. Second, if the tool offers a quality slider, around 75–85% usually looks identical to the original while keeping the file small. Save the WebP file, then upload it to your post exactly as you would a JPG or PNG.
Video
To add a video, paste its link into the video URL field. You do not need embed codes or iframes — paste the ordinary public page URL and your store converts it into a proper inline player automatically. YouTube (including Shorts) and Vimeo are supported, and you can paste a standard watch link, a short share link, or an existing embed link; all of them work.
For a post that is mainly about the video, also set the post's content type to Video (covered in the post-settings guide) so the clip is brought to the front and labelled correctly. A video can equally be dropped into an otherwise text-based article — just paste the URL and it will render where it belongs.
Audio
Audio works much like video, with two options. The first is to paste a link into the audio URL field. Public page URLs from SoundCloud, Spotify (episodes and shows), Buzzsprout, Anchor / Spotify for Podcasters, and Podbean are converted into an inline player automatically — again, no embed code needed.
The second option is to upload an audio file directly. Uploaded files must be MP3 or M4A and no larger than 50 MB. If you set both an audio URL and an uploaded file on the same post, the uploaded file wins and is the one that plays. As with video, set the post's content type to Audio when the recording is the main event so it is presented as a podcast-style post.
A quick summary
For images, upload a file or paste an image URL, and optionally add a thumbnail. For video, paste the page URL into the video field. For audio, paste the page URL into the audio field or upload an MP3/M4A under 50 MB. Whenever the media is the whole point of the post, set the matching content type so your store frames it correctly.
