Add your JP2 file
Drop one or more .jp2 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.
JP2 to TIFF
Converting a .jp2 image to .tiff re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .jp2 image to .tiff re-encodes the pixels for a different balance of size, quality, and support. A .jp2 file is a JPEG 2000 image in the boxed JP2 container: wavelet-compressed raster data plus the header boxes that declare its colour space and metadata. It was designed as JPEG's technical successor and, although the web never adopted it, it became the standard in digital cinema, medical imaging, and archival scanning.
A .tiff file is a Tagged Image File Format raster, the long-standing archival and prepress standard for images that must not lose a single bit. Its tag-based structure lets one .tiff hold multiple pages, layers of metadata, and pixel formats from 1-bit fax scans to 32-bit floating-point channels. For this route the practical draw is losslessly preserves any bit depth and color space you throw at it and decades of stability make it the safest long-term archival bet — balanced against files are huge — often 10x a visually identical JPEG, which is worth knowing before you commit a large batch.
Why convert JP2 to TIFF?
The practical trigger for this conversion is usually a mismatch: with .jp2, no mainstream browser decodes it, and Safari dropped its support, so it is unusable for web delivery. Switching to .tiff buys you losslessly preserves any bit depth and color space you throw at it, which is why it is the better fit for archival masters for museums, libraries, and digitization projects. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
JP2 vs TIFF at a glance
| Aspect | JPEG 2000 image (.jp2) | TIFF image (.tiff) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | discrete wavelet transform: the reversible LeGall 5/3 filter for lossless coding and the irreversible CDF 9/7 filter for lossy | structured as Image File Directories (IFDs) of numbered tags, allowing multiple images per file |
| Strongest at | digital cinema packages, where the DCI specification mandates JPEG 2000 for the picture track | archival masters for museums, libraries, and digitization projects |
| Weak spot | no mainstream browser decodes it, and Safari dropped its support, so it is unusable for web delivery | files are huge — often 10x a visually identical JPEG |
| Metadata | the JP2 container holds an ICC profile in its colour specification box and can carry XMP in a UUID box, EXIF in a UUID box, arbitrary XML, and an intellectual-property box. This converter reads the pixels only; header boxes are not carried into the raster outputs | eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags |
Pick TIFF as the output
Select .tiff in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TIFF is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TIFF file. Outputs keep the original filename with the .tiff extension.
JP2 to TIFF questions, answered
Will converting JP2 to TIFF lose quality?
No new loss is introduced — since jp2 is lossy-oriented and tiff is lossless-oriented, everything the .jp2 file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .tiff does not "restore" quality.
Is it private to convert JP2 files here?
Yes — the .jp2 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.
Where will the TIFF file work?
Every serious image editor, scanner driver, and DTP application on Windows, macOS, and Linux reads TIFF, and both major OSes preview it natively. Web browsers are the gap: Chrome, Firefox, and Edge will download rather than display a .tiff, so web delivery always requires conversion to PNG, JPEG, or WebP.
Will the TIFF file be bigger or smaller than my JP2?
Larger, sometimes much larger. A lossless .tiff must store every pixel or sample the decoder produced, without the perceptual shortcuts .jp2 used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my JP2 file?
In .jp2, the JP2 container holds an ICC profile in its colour specification box and can carry XMP in a UUID box, EXIF in a UUID box, arbitrary XML, and an intellectual-property box. This converter reads the pixels only; header boxes are not carried into the raster outputs. 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.
