APNG to TIFF Converter
Convert APNG to TIFF in your browser. APNG files usually come from animated stickers (LINE and Discord among others), UI animations and Firefox-era web graphics; TIFF is the better fit for printing, scanning and archival masters. You get an uncompressed 8-bit RGBA TIFF with the resolution recorded. Nothing is uploaded.

Why use Aback Images for apng to tiff
Where the TIFF goes next
TIFF opens in Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs.
TIFF next to APNG
The TIFF is written uncompressed, so expect it to be several times larger than the APNG, which stores lossless DEFLATE per frame, like PNG.
Written without a lossy pass
The TIFF is written uncompressed, so the pixels decoded from the APNG arrive unchanged.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
APNG vs TIFF
What changes from APNG to TIFF
Encoding: the APNG uses lossless DEFLATE per frame, like PNG; 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: 8 bits per channel in the APNG; TIFF allows 1 to 16 bits per channel, or 32-bit floating point, and the TIFF written here has 8 bits per channel.
Colour: RGB or an indexed palette in the APNG; TIFF supports RGB, CMYK, Lab, greyscale or palette, often with an ICC profile, written here as 8-bit sRGB.
Transparency: the APNG stores it as full alpha on every frame; the TIFF keeps it as an extra sample declared in the ExtraSamples tag.
Animation: fcTL frame-control chunks with fdAT frame data after the first image; the TIFF holds one image, so only the first frame is converted.
Metadata: the APNG can carry the same text and ICC chunks as PNG; TIFF can carry EXIF, XMP, IPTC and ICC, all stored as tags, but nothing is copied across.
About APNG
APNG extends PNG with animation frames. Unlike GIF it keeps full 24-bit colour and smooth 8-bit transparency, at the cost of larger files.
An APNG is a valid PNG with an acTL chunk announcing the frame count and loop count; each later frame is an fcTL chunk (size, offset, delay, blend and dispose rules) followed by fdAT data. Software that does not know APNG simply shows the first frame.
APNG files usually come from animated stickers (LINE and Discord among others), UI animations and Firefox-era 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 APNG to TIFF makes sense
TIFF is the better choice for printing, scanning and archival masters, while APNG suits high quality animated stickers and UI animations.
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
- APNG frames are full colour, so a GIF target has to reduce each frame to 256 colours.
- 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 APNG to TIFF lose quality?
TIFF is written uncompressed, so the pixels are stored exactly as decoded.
Is transparency kept in the TIFF?
Yes. APNG stores it as full alpha on every frame, and the TIFF is written with an alpha channel, so transparent areas stay transparent.
Will my animated APNG stay animated?
No. TIFF holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
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.
