Data URI
Build or decode data: URLs from files or text. Get CSS, HTML, and Markdown snippets, live MIME/size info, image preview, and download, all in this tab.

Runs in your browser. Nothing is uploaded.
How it works
Encode a file or text
Drop any file up to 10 MB, or type text with a MIME type (optional Base64). The data: URL appears on the left.
Pick a snippet
Switch between raw URI, CSS background-image, HTML img/object, or Markdown. Copy or download the snippet.
Decode and preview
Paste an existing data URI to see MIME, size, image preview, and download the original bytes.
What is a Data URI?
A data URI (RFC 2397) packs media type and payload into a single URL, often as Base64. Data URI is part of Easy24’s conversion toolbox. Your input stays in this tab for normal use; Easy24 does not upload that content to process it. On the free plan you get 5 uses per day and files up to about 10 MB. Limits are shown before you download. Typical flow: Drop a file (free: 5/day, 10 MB) or encode text. Switch snippet type for CSS/HTML/Markdown. Paste a data URI to preview and download the bytes. Related tools and reverse conversions appear on the page when a follow-up step is common.
Why use this tool
- File and text → data URI in the browser
- CSS, HTML img/object, and Markdown snippets
- Live MIME type and byte size
- Image preview for image/* URIs
- Decode and download any valid data URI
- Free plan: 5 uses per day, 10 MB max
Questions
What is a data URI?
A data: URL embeds file bytes (often Base64) directly in HTML, CSS, or Markdown so you do not need a separate file request.
How do I use this tool?
Drop a file or encode text to build a data URI, choose a snippet format, or paste a data URI to preview and download.
When should I avoid data URIs?
Very large assets bloat HTML/CSS and hurt caching. Prefer normal URLs for big images and use data URIs for small icons or inline SVGs.

When to use Data URI
Data URI is one of those utilities you open for a few minutes, finish the task, and close without leaving a trail of uploads. Build or decode data: URLs from files or text. Paste carefully: whitespace and encoding choices change the output. Use the reverse tool on the page when you need to go back. Search results often mix upload-based converters with local tools. Read the privacy note on this page so you know which model you are using. On Easy24, normal use of this tool keeps processing in your browser. That means the content you paste or the file you pick does not need to be uploaded to finish the job. The free plan allows 5 uses per day and files up to about 10 MB; limits appear before download.
