Why is the file bigger than the PNG?

TIFF here is uncompressed RGBA, so the files run larger than PNG's lossless compression. You trade size for broad print and editing compatibility.

Is transparency preserved?

Yes. TIFF stores an alpha channel, so transparent PNG pixels stay transparent.

PNG to TIFF

Writes your PNG into lossless TIFF with transparency intact.

What this does

This redraws each PNG onto a canvas and writes it out as an uncompressed RGBA TIFF. The conversion is lossless and keeps transparency, so the output suits print and editing workflows, though the file runs larger than PNG's compressed form.

How it works

1Drop your PNG images.
2Each one gets re-encoded as an uncompressed TIFF.
3Download each one, or grab them all as a zip.
