PNG TO TIFF CONVERTER
Convert a PNG to LZW-compressed TIFF, losslessly.
Your file is uploaded only for the moment it takes to convert, then deleted from the server straight away. It is never stored, indexed, or shared.
Lossless at Both Ends
Unlike the JPG route, this one really is lossless end to end: PNG stores exact pixels, LZW-compressed TIFF stores exact pixels, and the conversion is a repackaging rather than a re-encode. The reason to do it is almost always that something downstream insists on TIFF — print production, scientific imaging, document management systems and publisher submission portals all tend to. Expect the file to grow. LZW is a more conservative compressor than PNG's Deflate, so a TIFF of the same image is commonly two to three times larger.
Privacy Note
This conversion runs on our server. Your file is uploaded only for the seconds the conversion takes and is deleted immediately afterwards — it is never stored, indexed, or shared. Accepted input: PNG, up to 40 MB.
Key Features
- Genuinely lossless in both directions — the pixels round-trip exactly
- LZW compression for compatibility with print and archival software
- Accepts files up to 40 MB to allow for the larger output
- Expect roughly 2-3x the source size; that is LZW, not a fault
