TIFF to PNG – Lossless Conversion for Editing and Web

TIFF and PNG are both lossless formats, so converting between them produces a pixel-perfect copy — no quality is sacrificed in the process. The practical reason to make the switch: PNG is far more widely supported by web browsers, apps, and design tools, while TIFF's main stronghold is print and archival workflows. PNG gives you the same lossless quality in a format that works everywhere.

Transparency: TIFF to PNG without losing alpha

TIFF supports alpha channels — some TIFF files from design or imaging software carry transparency data. PNG preserves that alpha channel faithfully. Transparent areas in the source TIFF appear as transparent pixels in the PNG, with no fill color applied. This makes TIFF-to-PNG a clean conversion for graphics and composites that need to maintain their transparent backgrounds for web use or further editing.

File size: why PNG is typically smaller than TIFF

TIFF can store data in several compression modes — some uncompressed, some using LZW or ZIP internally. Uncompressed TIFF files are enormous. PNG uses DEFLATE compression consistently and tends to produce smaller files for the same lossless content, especially for photographic images. Converting from an uncompressed TIFF to PNG often reduces file size by 30–60% with zero quality change.

FAQ

Is TIFF to PNG truly lossless?

Yes. Both are lossless formats. The conversion is a pixel-for-pixel transfer with no compression artifacts introduced.

What happens with a multi-layer Photoshop TIFF?

The converter processes the flattened composite image. Photoshop layer structure isn't preserved — PNG doesn't support layers.

Can I batch-convert scanned TIFF documents to PNG?

Yes. Up to 200 files per run, up to 80 MB each. A ZIP bundles all the PNG outputs.

What about 16-bit TIFF files from a scanner or camera?

16-bit depth TIFFs are supported. PNG can store 16-bit per channel data, so the bit depth is preserved in the output.
