Markdown image syntax, explained
The standard Markdown image syntax is : an exclamation mark, alt text in square brackets, then the image URL in parentheses. Embed image in Markdown documents (GitHub READMEs, docs, blogs) with this pattern and the renderer displays the picture inline. To add image to Markdown GitHub README files reliably, always use an absolute https:// URL — relative paths break when the README is viewed outside your repo.
Two upgrades cover the gaps of plain syntax: a linked image [](target-url) makes the picture clickable, and reference-style image Markdown (![alt][logo] plus a [logo]: url definition) keeps long URLs out of your paragraphs. Neither plain nor reference-style Markdown can resize — for Markdown image size control, emit an HTML <img> tag with width/height instead, which most Markdown renderers pass through unchanged.

Frequently asked questions
Why can’t I resize an image with pure Markdown image syntax?
Standard Markdown image syntax  has no dimension attributes — the spec only defines alt text, URL and an optional title. Every renderer therefore displays the image at its natural size. If you need a thumbnail, fixed width or height, use the HTML fallback mode of this markdown image generator, which emits
that Markdown renderers (GitHub, most static site generators) pass through untouched.
When should I use HTML <img> instead of Markdown image syntax?
Use HTML when you need sizing (width/height), lazy loading, CSS classes, alignment or captions — none of which pure Markdown supports. Use plain Markdown image syntax  for simple embeds in READMEs, docs and blog posts where portability matters, because some strict renderers (chat apps, Slack) strip raw HTML while rendering standard image syntax.
What is the difference between Image to MD and URL to MD Link?
Image to MD generates image embeds —  — which render the picture inline. URL to MD Link generates text hyperlinks — [link text](page-url) — which render clickable text. Images start with an exclamation mark; links do not. If you want a clickable image (a picture that links somewhere), use the linked-image mode here: [](target-url).
How do I write good alt text for Markdown images?
Describe what the image shows in one short sentence, as if explaining it to someone who cannot see it — screen readers announce it, search engines index it, and it displays if the image fails to load. Keep it under ~125 characters, skip phrases like "image of", and leave alt empty () only for purely decorative images. This tool escapes brackets in your alt text automatically so the syntax never breaks.
Why is my Markdown image not showing on GitHub?
The four usual causes: the URL is relative (READMEs need absolute https:// URLs — use the validator warnings above), the host blocks hotlinking, the file extension is wrong or missing (case, query strings and redirects confuse some renderers), or the URL contains spaces or parentheses that were never encoded. Paste the URL into this image to markdown converter first — it flags each of these problems and percent-encodes spaces for you.
Which characters must be escaped in Markdown alt text and titles?
In alt text, escape square brackets as \[ and \] — an unescaped ] ends the alt text early and breaks the embed. In titles, escape double quotes as \" because the title is wrapped in "...". In the URL itself, encode spaces as %20; if the URL contains parentheses, CommonMark requires wrapping the whole destination in angle brackets: ![alt](). This generator applies all of these rules automatically.
How does batch mode turn many URLs into a Markdown gallery?
Paste one image URL per line, optionally followed by " | alt text". Batch mode validates every URL, generates one embed per line and joins them with blank lines — which most renderers display as a vertical gallery. In reference-style mode it additionally collects all [ref]: url definitions into one block at the bottom, keeping long URLs out of your paragraphs.
