TIFF to PNG

How it works

TIFF is common in scanning, printing and professional photo workflows, but almost nothing on the web displays it directly. PNG carries the same lossless accuracy while opening everywhere. This tool converts TIFF images to PNG directly inside your browser tab — no server, no upload, no waiting in a queue.

When you drop a file, Moyang reads its first bytes to confirm it's really a TIFF, then hands the bytes to a background Web Worker, where a dedicated TIFF decoder unpacks the first page's pixels — including any alpha channel, carried straight through. If the file has more than one page — common for scanned multi-page documents — only the first is converted, and the row is flagged. Your original file is never modified, and nothing ever leaves your device.

Because everything runs locally, there's no 10-conversions-a-day limit, no 100MB cap, and no processing queue — the kind of restrictions server-based converters impose to control their hosting bill. Convert one file or fifty; once a batch is done, download every result at once as a single ZIP.

Limitations

Multi-page TIFFs only get their first page converted — batch splitting per page isn't supported yet. Images over 100 megapixels aren't converted — decoding runs entirely in your browser's memory, and a file that large risks crashing the tab before it even gets to PNG encoding.

FAQ

Is this TIFF to PNG converter really free?

Yes — completely free, with no file size limits, no daily quota, and no account required. All conversion happens in your browser, so there's no server cost to recoup.

My scanner saved a multi-page TIFF — what happens to the other pages?

Only the first page is converted to PNG; if more pages exist, the converted row is flagged so this is never a silent surprise. Per-page batch splitting for multi-page TIFF is planned as a future improvement.

Why convert to PNG instead of keeping TIFF?

TIFF is barely supported on the web — most browsers won't display it inline at all — while PNG opens everywhere and is what design tools and content systems expect. Converting keeps the same lossless quality while making the file actually usable outside specialist software.

Is transparency preserved?

Yes. TIFF can carry an alpha channel, and any transparency in the source is carried straight through to the PNG output — no compositing needed, unlike converting to a format without transparency support.
