Percentage of the original dimensions.
sRGB is right for screens and the web. Keep the original for print workflows; grayscale discards color.

How to use this tool
- 1
Upload the .jp2 files
Pages, scans or tiles from an archive download, up to 20 per batch and 95 MB each.
- 2
Keep quality at 90
Quality is set to 90 so fine print and map lines survive. Use Resize if a scan is far larger than you need.

JP2 to JPG for archive, library and satellite downloads
JPEG 2000 was published by the Joint Photographic Experts Group as ISO/IEC 15444-1 in 2000, meant as the successor to the 1992 JPEG. It replaced JPEG's blocks with a wavelet transform, added a true lossless mode and let a file be decoded progressively by resolution or region. The web never adopted it: Chrome, Firefox and Edge do not display JP2, and Windows Photos does not open it either.
Institutions with huge image collections went the other way. Digitized newspaper pages, scanned books, historical maps and satellite tiles are often stored and offered for download as .jp2. That is fine on the provider's servers and a dead end on your laptop. Converting to JPG gives you a file you can annotate, crop, print or attach to a report.

JP2
JPEG 2000
JPEG 2000 is a wavelet-based image standard published by the Joint Photographic Experts Group in 2000. It supports lossless and lossy compression, high bit depths, transparency and progressive decoding, and avoids JPEG's blocky artefacts. It is used in digital cinema, medical imaging, satellite imagery and library archives. Web browsers and most consumer apps do not support it, which limits everyday use.

JPEG image
JPEG (or JPG) is the most widely used photo format, standardised by the Joint Photographic Experts Group in 1992. It uses lossy compression that discards fine detail the eye is unlikely to notice, which keeps photos small enough for the web, email and phone storage. It handles smooth gradients and natural scenes well, but sharp text, line art and flat colours pick up visible blocky or fuzzy artefacts. JPEG has no transparency and no animation, and every re-save loses a little more quality. Every browser, phone, camera and image editor can open it.

People convert JP2 to JPG after downloading a page, a map or a photograph from a library, archive or satellite portal that stores JPEG 2000 masters, because their own computer, phone or editor cannot open the file.
What changes when a wavelet JP2 becomes a JPG
Kept in the JPG
- Full pixel dimensions
- Embedded color profile
- Grayscale or color look
- Readable text and line work at quality 90
Lost or reduced
- Lossless pixel accuracy
- 16-bit tonal depth, cut to 8 bits
- Region and resolution streaming
- Transparency, filled with a background
Archive scans are often very large in pixels, for example a full newspaper page at 400 DPI, so the JPG can run to several megabytes even with good compression. If you only need to read or quote the page, set Resize to a longest side of 3000 px. For a stack of page images that should end up as one document, our guide on scanning documents to PDF shows the next step, and the image compressor brings individual pages under an upload cap.
JPEG 2000 to JPG questions
Why do library and archive downloads come as JP2?
JPEG 2000 can be lossless or close to it at much smaller sizes than TIFF, and servers can pull a zoomed-in region or a low-resolution view out of one file without decoding all of it. That suits collections with millions of large page scans, which is why digital libraries adopted it.
Can I convert frames from a digital cinema package?
Not directly. A DCP stores its JPEG 2000 frames as codestreams inside MXF files, not as separate .jp2 images, and this page accepts .jp2 files only. Frames have to be extracted with DCP tools first.
Is a JPG made from a lossless JP2 still an exact copy?
No. Lossless JPEG 2000 reproduces the original pixels perfectly, but JPG compression always discards some detail. At quality 90 the difference is invisible for reading and sharing; keep the JP2 as the archival master.
Why is my JPG larger than the JP2 it came from?
JPEG 2000's wavelet compression is more efficient than JPEG's 8 × 8 blocks, especially for large scans, so the same visual quality takes more bytes as JPG. Lower Quality or resize the page if the file has to fit an email or a form.
Do 16-bit grayscale scans keep their tonal range?
JPG stores 8 bits per channel, so 65,536 gray levels become 256. That is plenty for reading text or viewing a photograph on screen, but not for measurement work; for that, keep the JP2 or convert to TIFF.
What about .j2k, .jpf or .jpx files?
They are related JPEG 2000 variants: a bare codestream, and extended containers from Part 2 of the standard. This converter takes .jp2; if a tool can re-save the image as .jp2 or TIFF, the TIF to JPG page handles the rest.
