Why PNG instead of JPG?
Both JPG and PNG are standard image formats, but they handle quality very differently. JPG uses lossy compression — it discards some image data to reduce file size. PNG is lossless: every pixel is preserved exactly as it was in the original DICOM.
For medical scans, this distinction matters when you need images for a publication, academic report, or medical presentation; when you want to zoom in tightly without compression artifacts; or when you've been asked specifically for a lossless format.
How DICOM-to-PNG export will work
The converter is nearly ready. Here's how it will work once launched.
-
Drop your DICOM file or folder
Drag and drop into the dropzone, or click to choose. The converter reads the DICOM data locally — nothing is uploaded.
-
Choose the slice
For multi-slice studies (MRI, CT), you'll pick the slice you want as PNG. Single-image DICOMs (X-rays) export automatically.
-
Download your PNG
The PNG downloads directly to your computer. Lossless, full-resolution, no watermark.
PNG vs JPG vs PDF — which format should you choose?
PNG is the right choice when quality is the priority: publications, printed materials, presentations, or situations where you need a pixel-perfect lossless image.
JPG is the right choice when file size matters more: emailing a scan to a family member, sharing on a phone, or attaching to an online form. The quality difference is usually invisible in practice.
PDF is best when you want a document-style output: multiple slices, captions, or a report format. OpenMyScan will offer all three export formats.
Questions people actually ask
Is the PNG converter available now?
Not quite — it's launching soon. In the meantime, DICOM to JPG is fully available and works with all scan types.
What's the difference between PNG and JPG for a medical scan?
PNG is lossless — every pixel is preserved exactly. JPG uses lossy compression that can introduce subtle artifacts at high zoom levels. For personal viewing and sharing, JPG is usually fine. For publications or detailed clinical review, PNG is safer.
Will the PNG file contain patient data?
By default, yes — DICOM files contain patient name and ID. If you want to remove that information first, use our DICOM Anonymizer tool before exporting.
Are my files uploaded anywhere?
No. All processing happens locally in your browser. Files never leave your device.
Will there be batch export?
Single-slice export will be available on the free tier. Batch export of full series is planned for OpenMyScan Pro.
What scan types will be supported?
PNG export will work with MRI, CT, X-ray, and ultrasound — any study that opens in the standard DICOM viewer.
