Output naming & batch behavior

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

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 Animated PNG to Image palette JSON

Before you start

Drop one or more Animated PNG files; this format cannot be pasted as plain text.

Accepted: .apng, .png · image/apng

Choose or drag one or more Animated PNG files onto the drop zone.
Confirm the detected format and adjust the available settings. Mixed-format batches are flagged before conversion.
Select “Convert on this device.” Produces JSON with HEX/RGB values, sampled pixel counts, percentages, and transparency coverage.

How this converter behaves

The browser decodes the image into pixels and re-encodes those pixels in the destination format.

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 structural. The converter preserves meaning and structure supported by both formats.

Animated input is flattened to its first frame on this static-image route.
Colors are quantized into bounded RGB buckets and sampled on very large images; this is a practical dominant-color palette, not a color-managed scientific analysis.
