How it works
Important
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
Image-to-Base64 mode reads the selected file into a standards-based data URL that includes its MIME type. Reverse mode validates the data URL prefix and decodes the payload before enabling preview and download.
Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.
Questions
No. Base64 usually increases the byte size by roughly one third and is best for small embedded assets.
No. It must decode to supported image data and should include a valid image data URL MIME prefix.
Open-source foundations
Lucaden documents its standards sources, architectural references, and permissive runtime dependencies while keeping this workspace consistent with the Lucaden interface.
