What PNG to TIFF conversion does

Convert a PNG image to TIFF directly in your browser. TIFF is the standard for print production, scanning, publishing, and archival master copies, where lossless fidelity matters more than file size.

How to convert PNG to TIFF

1. Choose a PNG file.
2. Select Convert & download.
3. Save the .tiff file from your browser downloads.

Why use this conversion

Print shops, scanning pipelines, and archival workflows often specifically require TIFF as the master format, since it stores pixel data without the lossy compression JPEG uses.

Transparency and output quality

Output is uncompressed 8-bit RGBA, so an alpha channel from the source PNG is preserved. This tool writes uncompressed TIFF (raw RGBA pixel data), so the file can be several times larger than the source PNG, which already uses deflate compression.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: PNG (.png) only, up to 25.0 MB and 8,192 px per side.
• This is a standard baseline uncompressed TIFF. Software expecting a specific compressed TIFF variant (LZW, ZIP) should still be able to open it, since compression is optional in the TIFF spec.
• Metadata is not preserved in the downloaded file.

PNG to TIFF FAQ

Why convert PNG to TIFF?

TIFF is the standard for print production, scanning, publishing, and archival master copies, where lossless fidelity matters more than file size.

Does TIFF output keep transparency?

Yes. Output is uncompressed 8-bit RGBA, so an alpha channel from the source PNG is preserved.

Why is the TIFF file so much larger than the source PNG?

This tool writes uncompressed TIFF (raw RGBA pixel data). PNG uses deflate compression; TIFF here does not, so the file can be several times larger for the same image.

Will every TIFF reader open this file?

It is a standard baseline uncompressed TIFF, which is broadly supported. Some software that expects a specific compressed TIFF variant (LZW, ZIP) may still open it, since compression is optional in the TIFF spec.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
