Convert DICOM to WebP
DICOM is the image format used for medical scans like MRI, CT, and X-ray, and WebP is a compact format built for the web. To convert DICOM to WebP, open the file in a converter and export it as WebP. Doing this on your own computer means the scan, and the patient details stored inside it, never get sent anywhere.

How to convert DICOM to WebP

- Choose WebP as the output format.
- Convert. The WebP images are written to your folder, and nothing leaves your machine.
DICOM vs WebP: what actually changes
| DICOM | WebP | |
|---|---|---|
| Opens everywhere | No, needs specialized medical imaging software | Yes, opens in any modern browser or image app |
| File size | Large, stores full uncompressed pixel data | Much smaller, compressed for web use |
| Quality | Lossless, preserves every diagnostic detail | Very good, but lossy by default, so some fine detail is discarded |
| Transparency | No | Yes |
| Patient metadata | Yes, name, ID, birth date, and study details embedded in the file | No, that metadata isn't carried over |
When to convert, and when not to
Convert DICOM to WebP when you need to share a scan image in a presentation, a report, or on a website, where a small, universally viewable file matters more than diagnostic-grade detail.
Keep the DICOM original for anything clinical or diagnostic, since a WebP export is lossy, drops the patient and study metadata, and isn't meant for medical record keeping.
Why not just use an online converter?
A DICOM file usually has patient details, like name, birth date, and medical record number, written into its header alongside the scan itself. Send that file to an online converter and those details go along with it, to a server you don't control. Converting on your own computer keeps the scan and everything attached to it on your machine the whole time.
Questions
Does converting DICOM to WebP lose image quality?
Yes, some. DICOM stores the scan losslessly, and WebP compresses it, so there's a quality trade-off. For viewing or sharing it's usually fine, but it isn't suitable for diagnosis.
Does the WebP file keep the patient's name or other details?
No. The patient metadata stored in the DICOM header isn't carried into the WebP file, so the exported image is just the picture, not the record.
Can I convert DICOM scans without uploading them anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so the scan and any patient information in it never travel over the internet.
Why would someone convert a medical scan to WebP?
Mostly for sharing outside a clinical system, like putting a scan image in a slide deck, a research write-up, or a webpage, where the receiving software needs a common image format instead of DICOM.
Can I convert a whole folder of DICOM slices at once?
Yes, you can drag in an entire folder and convert every slice to WebP in one pass, rather than opening each file individually.
