Add your TIF file
Drop one or more .tif files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .tif image to .apng re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .tif image to .apng re-encodes the pixels for a different balance of size, quality, and support. A .tif file is an ordinary TIFF image wearing the three-letter spelling of the extension; the bytes inside are identical to a .tiff. The shorter form comes from the MS-DOS era, when the FAT file system's 8.3 naming rule allowed only three characters after the dot, and it stuck as the default on Windows software ever since.
An .apng file is an animated extension of PNG: full 24-bit color with 8-bit alpha per frame, in a stream that plain PNG decoders read as a normal still image. It delivers the smooth, semi-transparent animation that GIF's 256-color palette never could, and it is the format behind many messaging-app sticker packs. For this route the practical draw is 16.7 million colors and real alpha per frame, versus GIF's 256 and binary transparency and backward compatible: old decoders still render the first frame — balanced against files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .tif, dual spellings trip up strict file-type filters and deduplication scripts. Switching to .apng buys you 16.7 million colors and real alpha per frame, versus GIF's 256 and binary transparency, which is why it is the better fit for animated stickers (Apple's iMessage and LINE both build on APNG). Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | TIFF image (.tif) | Animated PNG (.apng) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | bitstream-identical to .tiff: an IFD-and-tag structure defined by the TIFF 6.0 specification | adds three chunk types to PNG: acTL (animation control), fcTL (frame control), and fdAT (frame data) |
| Strongest at | document-imaging and fax archives, which overwhelmingly use the three-letter form | animated stickers (Apple's iMessage and LINE both build on APNG) |
| Weak spot | dual spellings trip up strict file-type filters and deduplication scripts | files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better |

Select .apng in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if APNG is selectable, the route is real and validated.
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid APNG file. Outputs keep the original filename with the .apng extension.
Since tif is lossless-oriented and apng is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .apng itself requires.
Yes — the .tif file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Chrome 59+, Firefox 3+, Safari 8+, and Edge 79+ all animate .apng natively, so browser coverage is complete. Desktop support is patchier — most image editors open only the first frame — and social platforms frequently flatten or re-encode uploads, so test the target platform before committing to it.
It depends on the content: adds three chunk types to PNG: acTL (animation control), fcTL (frame control), and fdAT (frame data). Convert one representative file first and compare before batch-processing a large set.
In .tif, identical to .tiff — native EXIF tags, XMP, IPTC, and ICC profiles all persist regardless of which extension spelling the file uses. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
