DICOM to PNG8 Converter
Processing entirely on your device — large files may take a moment.
Convert PNG8 files like any PNG — to JPG, WebP or full-color formats. If your files are still in DICOM format, this page is the shortcut: DICOM is the ISO standard for medical imaging — CT/MRI slices carry patient metadata, window/level display parameters and pixel data in one file. Only uncompressed transfer syntaxes are supported.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the DICOM format
DICOM is the ISO standard for medical imaging — every CT/MRI slice bundles patient metadata, display parameters (window centre/width) and pixel data. The converter renders uncompressed transfer syntaxes through proper window/level mapping, exactly as a workstation would show it.
Patient and study metadata (name, ID, modality, date) are exported alongside the image as a text sidecar. Compressed transfer syntaxes (JPEG inside DICOM) are out of scope and reported clearly.
+ Strengths
- ✓Correct window/level greyscale mapping
- ✓Metadata exported as a text sidecar
- ✓MONOCHROME1/2, RGB and rescale handled
! Limitations
- −Compressed transfer syntaxes unsupported
- −Multi-frame volumes take the first frame
- −Huge CT stacks render slice by slice
About the PNG8 format
PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.
Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.
+ Strengths
- ✓Truly lossless — every pixel survives exactly as it was
- ✓Full alpha transparency with smooth edges, not 1-bit masks
- ✓Open standard, unpatented, with excellent tooling everywhere
- ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp
! Limitations
- −Photographs become several times larger than JPG
- −Base format has no animation (that is the APNG extension)
- −16-bit or high-resolution PNGs can grow very heavy
Why convert DICOM to PNG8?
There is a concrete reason this conversion exists: Compressed transfer syntaxes unsupported PNG8 sidesteps that — Truly lossless — every pixel survives exactly as it was If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this DICOM to PNG8 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 DICOM to PNG8?
No — PNG8 is a lossless format, so every pixel of the converted image matches your original DICOM 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 DICOM files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to PNG8?
Transparency is kept whenever PNG8 actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
