1. Drop your files
One .dcm file, a selection, a whole study folder, or a .zip archive. Multi-frame files are expanded automatically.

DICOM to JPEG converter
Turn .dcm files into ordinary .jpg images you can email, print or drop into a document, with the brightness and contrast your scan was meant to be viewed at. Everything runson your computer. Nothing is uploaded.
Drop your DICOM files, study folder or .zip here
Nothing is uploaded. Files are read and converted on this computer.
CT presets
100% local: your files are read and converted in your browser and never uploaded.
How it works
Three steps, all of them on your own machine.
2. Set the window
The file's own brightness and contrast are used by default. Adjust them, or pick a CT preset, and watch the preview.
3. Save the images
A single image downloads as .jpg. A batch comes back as a .zip holding a folder of your images, mirroring the original structure.
Format
What you gain, and what you lose
A JPEG opens anywhere: in an email, a phone gallery, a word processor, a slide deck. That convenience costs the two things that make DICOM diagnostic, so it is worth being clear about the trade.
Good for sharing
Sending an image to a clinician, illustrating a question, putting a figure in a report, a paper or a presentation.
Loses the bit depth
16-bit pixels become 8-bit. The window you choose is baked in, and nobody downstream can re-window to look at bone and soft tissue separately.
Loses the metadata
Scanner, sequence, slice position, spacing and study identifiers all live in the DICOM header and do not survive. Keep the originals.
Privacy by design
Your images never leave your device
Decoding and JPEG encoding both happen locally in your browser. Your files are never uploaded to DocOrbit or any third party, and nothing is stored on a server. If you later request a second opinion, your imaging is encrypted in transit and at rest and isnever used to train AI models.
No upload
Files are opened directly by your browser. They never touch our servers.
No account required
No sign-up, no login, no email, no watermark, no limit on how many files you convert.
Works offline
Once the page has loaded you can disconnect entirely and it still converts.
DICOM to JPEG FAQ
Are my images uploaded?
No. The files are read, decoded and encoded as JPEG entirely inside your browser, on your own computer. Nothing is sent to DocOrbit or any third party and nothing is stored on a server. Once the page has loaded you can go offline and it still works.
Why do other converters make my CT look grey and flat?
Because a DICOM pixel is usually 12 or 16 bits and a JPEG pixel is 8, so something has to decide which part of the range to keep. Converters that just stretch the full range produce washed-out images. This one uses the WindowCenter and WindowWidth stored in the file, the same values a radiologist's viewer uses, and gives you sliders plus CT presets for soft tissue, lung, bone and brain if you want something different.
Can I convert a whole folder or a .zip at once?
Yes. Drop a folder, a .zip archive, or a selection of files, and every image is converted into a .zip containing a folder named after what you dropped, mirroring the original structure. A .zip you drop is read in place rather than extracted: each file inside is decompressed only when it is needed, so a zipped study uses no more memory than loose files. Multi-frame files produce one JPEG per frame.
Which DICOM files are supported?
CT, MRI, X-ray, ultrasound, PET, mammography and secondary capture, whether uncompressed or stored as RLE, JPEG baseline, JPEG lossless, JPEG-LS, JPEG 2000 or HTJ2K. Colour ultrasound and palette-coloured nuclear medicine images keep their colour.
Is a JPEG good enough for a diagnosis?
No, and you should not treat it as one. A JPEG is 8-bit and lossy: it throws away the bit depth that lets a radiologist re-window the image, and it drops the metadata that records what was scanned and how. It is the right format for sharing an image, putting one in a report or a slide, or illustrating a question. For an actual read, keep the original DICOM.
Does it remove patient details?
Partly, and not by design. Patient name and identifiers live in the DICOM header, which is not carried into the JPEG, so they are not in the file's metadata. But anything burned into the pixels themselves, which is common on ultrasound and secondary capture images, stays visible. Check the image before you share it.
Can a radiologist review my scan?
Yes. DocOrbit provides independent second opinions on radiology and nuclear medicine imaging, AI-supported and verified by a board-certified, subspecialty-matched radiologist, typically within 24 to 48 hours.
