What Image Base64 Encoder does
Copy the complete snippet
Copy transfers the complete result, even when the preview is shortened.
Choose a snippet format
Pick Raw Base64, Data URI, HTML, CSS or Markdown for each image.
Add alt text and decorative flags
For HTML or Markdown, describe an informative image or mark it decorative. Missing details are shown before the snippet is ready.
Build a set from several images
Choose which images belong to the set, then check the proposed names.
Check the size before you share
See the full Copy and Files sizes separately. Add your own byte limit if a destination restricts the output.
Save files without overwriting
Choose a local folder and see which files were saved. Existing files are never replaced.

Questions
Does it change my original files?
Original image bytes are not resized or recompressed. Copy transfers the complete result.
Which formats does it output?
Single images produce Raw Base64, Data URI, HTML, CSS or Markdown. Sets can also produce JSON.
Does it overwrite existing files?
No. Existing files are never replaced when the set is saved.
Can it decode Base64 back into images?
No. It is designed for compact image snippets and sets, not arbitrary Base64 decoding.
