Good to know
TIFF is a professional-imaging container — scanners, faxes, medical devices, and print workflows lean on it because it supports layers, multiple pages, and lossless compression schemes like LZW and Deflate. The catch is that browsers never adopted it, so a TIFF won't preview inline or embed in a web page. Converting to PNG gives you a universal, lossless equivalent that renders identically in any tool or browser.
The two properties worth protecting during conversion are transparency and page count. An RGBA TIFF round-trips into an RGBA PNG with its alpha channel intact, so cut-outs and logos keep their transparency. Multi-page TIFFs — the norm for scanned documents and multi-frame captures — are split into one PNG per page, with the page number in each filename, and the whole set bundles into a ZIP.
Be aware of bit depth. TIFF commonly stores 16 bits per channel for high-dynamic-range and medical imaging, but the browser canvas that drives PNG export works in 8 bits per channel, so the output is downsampled. For everyday viewing and sharing that is invisible; if you genuinely need to preserve 16-bit data for further editing, use a desktop tool like ImageMagick instead.
Once you have PNGs, a lossless format is large — run them through an image compressor, or convert photographic pages to JPG when transparency isn't needed and file size matters more.
Frequently asked questions
- Why doesn't TIFF open in my browser directly?
- TIFF is a flexible, professional-imaging format that browsers never bothered to support natively — it has dozens of compression and tag variants. PNG is universal, lossless and renders the same image in any tool.
- Are multi-page TIFFs handled?
- Yes — every page is decoded separately and exported as its own PNG file. Filenames include the page number.
- Will the alpha channel survive?
- Yes — RGBA TIFFs round-trip into RGBA PNGs with full transparency.
- Can it handle 16-bit-per-channel TIFFs?
- Yes for decoding, but PNG export is downsampled to 8-bit per channel by canvas. For full 16-bit work, use a desktop tool like ImageMagick.
- Are my files uploaded?
- No — UTIF decoding runs entirely in your browser. Nothing leaves your device.
