About TIFF to PNG
Where TIFF files come from
TIFF comes from scanners, fax software, microscopes, and print and publishing workflows. Browsers other than Safari, most websites, and design tools for the web can't show it. PNG keeps the same pixels and opens everywhere.
What changes
- Each page of a multipage TIFF becomes a separate PNG.
- 8-bit pixels are kept exactly, and transparency is kept.
- 16-bit TIFFs become 8-bit, and CMYK print files are converted to screen colour (RGB), so colours can shift slightly.
- Layers, colour profiles, and metadata are not kept.
Measured
Our 12-megapixel sample photo (4032 by 3024) saved as an LZW-compressed TIFF, converted in Chrome on a laptop. Phone timings are still to be measured.
| TIFF file | 15 MB |
|---|---|
| PNG file | 20 MB |
| Time in Chrome (laptop) | 0.9 seconds, including loading the TIFF reader |
In your browser
Safari reads single-page TIFFs itself. Chrome, Edge, and Firefox can't read TIFF at all, so they load a small TIFF reader (utif2, 31 KB) when you convert; it is also used for every page of a multipage file, in every browser.
Limits
- 16-bit and CMYK TIFFs lose their extra precision and print colour space.
- Every result stays in memory until you download it, so very long scans are best done in batches on phones.
- Rare compressions (such as JPEG 2000 inside TIFF) can't be read; the result says so for that file.
- Very large pages may be reduced to about 16 megapixels on iPhones. The result says so.
Other options
- TIFF to JPG: a much smaller file for photos and sharing.
- Image to PDF on Open PDF Toolkit: turn the scanned pages into one PDF.
- Compress image: shrink the PNGs by reducing their colours.
Questions
Is TIFF to PNG lossless?
Yes for 8-bit colour and greyscale TIFFs. PNG compresses without loss, so every pixel stays the same. 16-bit TIFFs are reduced to 8-bit.
Are my files uploaded?
No. Your files are processed on your device. We never upload them.
What happens with a multipage TIFF?
Every page becomes its own PNG, named with -page-1, -page-2, and so on. Download them one by one or all together as a zip.
Does it keep transparency?
Yes. TIFFs with an alpha channel keep it in the PNG.
Will the PNG be smaller than the TIFF?
Not always. For uncompressed TIFFs, usually yes. LZW and ZIP TIFFs are already compressed, so the PNG can be a similar size or a bit larger; our 15 MB LZW sample became a 20 MB PNG.
