Free online JP2 to TIF converter

Publishing, scanning, GIS, and document-management systems may require TIFF files and reject JPEG 2000 images. Converting a JP2 file to TIF creates a raster image that those applications can open, edit, print, or store.

What JP2 is

JP2 is the usual .jp2 file wrapper for JPEG 2000 image data. JPEG 2000 supports lossy or lossless compression, high bit depths, tiling, progressive decoding, embedded ICC color profiles, and optional alpha channels.

JP2 is used in digitized collections, high-resolution scans, geospatial imagery, scientific imaging, and some preservation workflows. Its software support is less universal than TIFF support because an application needs a JPEG 2000 decoder to open it.

What TIF is

TIF and TIFF refer to the Tagged Image File Format, normally stored as .tif or .tiff. TIFF can store grayscale, RGB, CMYK, alpha data, ICC profiles, metadata, 8-bit or 16-bit channels, and multiple images in one file.

TIFF is widely used by scanners, page-layout software, image editors, print workflows, and repositories. It supports uncompressed data and lossless compression such as LZW, ZIP/Deflate, and PackBits; TIFF can also contain JPEG-compressed image data, which is lossy and less consistently supported.

A TIFF is often much larger than a JP2 because JPEG 2000 can compress images efficiently. TIFF should be chosen when the receiving program requires it or when its compatibility matters more than file size.

Convert a JP2 file to TIF

For a single conversion without installing software, upload the JP2 file to the converter on 101convert.com, select TIF as the output format, start the conversion, and download the .tif file. Open the result in the program or device that requires TIFF before discarding the source file.

For local conversion or batches, ImageMagick is a practical option. Its ability to read JP2 depends on the installed build including JPEG 2000 support, commonly through OpenJPEG. Create a TIFF with lossless LZW compression using:

magick input.jp2 -compress LZW output.tif

Use Deflate compression when the destination application supports it:

magick input.jp2 -compress Zip output.tif

Check image dimensions, channel depth, colorspace, and embedded profiles before and after conversion:

magick identify -verbose input.jp2
magick identify -verbose output.tif

GIMP can also export TIFF if its installation can open the JP2 source. Open the file, choose File → Export As, enter a name ending in .tif, select Export, then choose LZW or Deflate in the TIFF export options.

Quality and compatibility limits

Converting a lossy JP2 to TIFF cannot restore detail removed when the JP2 was encoded. LZW and Deflate preserve the pixels decoded from the JP2 without adding another lossy compression stage.

Keep the source bit depth where the destination supports it. Saving a 16-bit image as 8-bit TIFF reduces tonal precision and can create banding in smooth gradients. Confirm that the target application accepts 16-bit TIFF before delivery.

Preserve an embedded ICC profile when color accuracy matters. Colors can change if a converter discards the profile, if the receiving application is not color-managed, or if RGB and CMYK are converted between one another.

JP2-to-TIFF conversion usually creates a single-image TIFF because most JP2 files contain one image. TIFF supports multi-image files, but it does not provide standardized editable layers; application-specific layer data should not be assumed to survive conversion.

Very large images can exceed the limits of classic TIFF and require BigTIFF. Check that the receiving software supports BigTIFF before converting large scans, maps, or scientific images.
