Output naming & batch behavior

Filename templateAvailable variables: {output} (converter’s meaningful name), {name}, {target}, {ext}, {index}. Duplicate names receive a safe numeric suffix.

Pipeline 1 linear · 0 branches

Why use A → B → C?

A pipeline feeds each result directly into the next compatible converter. Use one when the destination needs an intermediate representation or when you want to inspect and normalize that middle format.

JSON → CSV → XLSX turns records into rows before building a workbook.
Markdown → HTML → DOCX resolves markup before creating a document.
SVG → PNG → PDF intentionally flattens vector artwork before placing it on a page.

Only type-compatible next steps are offered. Lossy steps are marked before you run them.

About this conversion

How to convert SVG to Base64

Before you start

Paste SVG markup or drop an .svg file. Scripts and event-handler attributes are removed.

Accepted: .svg · image/svg+xml

Paste valid SVG content, choose files, or drag them onto the drop zone.
Confirm the detected format. Mixed-format batches are flagged before conversion.
Select “Convert on this device.” Produces previewable Base64 text and a correctly named download.

How this converter behaves

The SVG is sanitized and rewritten as inert framework source code. OmniCastConverter never evaluates the generated component.

What happens to your data?

The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.

Fidelity and limitations

This route is classified as lossless. The converter preserves meaning and structure supported by both formats.

The result is source text only and is never executed; review framework-specific accessibility props before shipping.

The “Use example” action in the workbench loads this exact input. Produces previewable Base64 text and a correctly named download.
