VICAR to JPC Converter
Processing entirely on your device — large files may take a moment.
VICAR is NASA/JPL's planetary image format — Mars rover and Voyager frames circulate in it, with a label block describing the instrument. Convert photos to JPC for streaming pipelines, or JPC back to JPG/PNG for everyday viewing.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the VICAR format
The VICAR Planetary Image coder of the ImageMagick set — the planetary-science format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
About the JPC format
JPC is JPEG 2000 stripped to its bare codestream: the same wavelet-compressed image data as JP2, minus the container boxes that give JP2 its metadata, color profiles and file signature. Broadcast and archival systems that stream codestreams directly (rather than storing boxed files) work with JPC.
Because there is no container, JPC carries no thumbnail, no EXIF and no declared colorspace — players must probe the codestream header itself. Converting JPC into JP2 restores a full container; converting to JPG or PNG produces an instantly viewable copy.
+Strengths
- ✓Wavelet compression, better per-byte quality than JPG
- ✓True lossless mode available
- ✓Streamable — no container parsing needed
!Limitations
- −No metadata, color profile or thumbnail
- −Browsers cannot open it at all
Why convert VICAR to JPC?
There is a concrete reason this conversion exists: Niche format — few modern readers JPC sidesteps that — Wavelet compression, better per-byte quality than JPG If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this VICAR to JPC converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting VICAR to JPC?
No — JPC is a lossless format, so every pixel of the converted image matches your original VICAR file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your VICAR files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several VICAR files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
