Why use Aback Images for png to tiff
Where the TIFF goes next
TIFF opens in Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs.
TIFF next to PNG
The TIFF is written uncompressed, so expect it to be several times larger than the PNG, which stores lossless DEFLATE with a prediction filter chosen per row.
Written without a lossy pass
The TIFF is written uncompressed, so the pixels decoded from the PNG arrive unchanged, apart from precision beyond 8 bits per channel.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
PNG vs TIFF
What changes from PNG to TIFF
Encoding: the PNG uses lossless DEFLATE with a prediction filter chosen per row; TIFF uses none, LZW, PackBits, Deflate or JPEG, chosen per file, and the download is an uncompressed 8-bit RGBA TIFF with the resolution recorded.
Bit depth: 1, 2, 4, 8 or 16 bits per channel in the PNG; TIFF allows 1 to 16 bits per channel, or 32-bit floating point, and the TIFF written here has 8 bits per channel. 16-bit PNGs from photo and scientific software are reduced to 8 bits per channel.
Colour: RGB, greyscale, or an indexed palette of up to 256 colours in the PNG; TIFF supports RGB, CMYK, Lab, greyscale or palette, often with an ICC profile, written here as 8-bit sRGB.
Transparency: the PNG stores it as a full alpha channel, so edges and shadows can fade smoothly; the TIFF keeps it as an extra sample declared in the ExtraSamples tag.
Metadata: the PNG can carry text chunks, an ICC profile, physical resolution and EXIF in an eXIf chunk; TIFF can carry EXIF, XMP, IPTC and ICC, all stored as tags, but nothing is copied across.
About PNG
PNG stores pixels losslessly with full alpha transparency. It is ideal for screenshots, logos, UI and anything with sharp edges, but photos saved as PNG are several times larger than JPEG.
A PNG opens with an 8-byte signature and is a chain of chunks, each with its own CRC: IHDR (size, depth, colour type), optional PLTE and tRNS for palettes, one or more IDAT chunks with the compressed rows, and IEND.
PNG files usually come from screenshots, design exports, logos and web graphics.
About TIFF
TIFF is the professional archive and print format. It can hold multiple pages, high bit depths and lossless data, and is common in scanning, publishing and GIS.
A TIFF begins with 'II' or 'MM' for the byte order and the number 42, then an offset to the first image file directory (IFD): a table of tags giving the size, compression, colour model and the location of the strips or tiles of pixels. Each further page is another IFD.
When converting PNG to TIFF makes sense
TIFF is the better choice for printing, scanning and archival masters, while PNG suits screenshots, logos, graphics and anything that needs transparency.
TIFF strengths: Lossless and print-ready; Multiple pages in one file; Preferred by print shops and archives. Drawbacks to weigh: Very large files; Browsers cannot display it; Many variants and compression schemes.
Limitations
- The TIFF is written uncompressed for maximum compatibility, so it is large; print shops and archives generally expect that.
- Browsers other than Safari do not display TIFF, so it is not a format for the web.

Frequently asked questions
Does converting PNG to TIFF lose quality?
TIFF is written uncompressed, so the pixels are stored exactly as decoded. 16-bit PNGs from photo and scientific software are reduced to 8 bits per channel.
Is transparency kept in the TIFF?
Yes. PNG stores it as a full alpha channel, so edges and shadows can fade smoothly, and the TIFF is written with an alpha channel, so transparent areas stay transparent.
Which apps open TIFF files?
Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs. It opens in Safari only; other browsers do not display TIFF.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
