DICOM to PDF converter
Convert DICOM to PDF online for free. Turn a scan or a whole series into a printable PDF with one, two or four images per page.
What it does
A PDF is the format to reach for when a scan has to be printed, filed or attached to paperwork. It keeps several images together in one document, prints predictably and opens on any device without a special reader.
You can put one image per page when detail matters, or two or four per page when you want an overview of a series without printing fifty sheets.
One, two or four images per page
Choose between detail and a compact overview.
Whole series in one document
Every loaded image becomes a page or a cell, in order.
Aspect ratio preserved
Images are fitted, never stretched — a distorted scan is useless.
Neutral document properties
No study or patient information is written into the PDF metadata.
How to use it
Load the study
Individual files or the ZIP.
Pick the layout
One image per page, or two or four.
Set the quality
Higher quality gives a larger PDF.
Download the PDF
Ready to print, email or file.
When people use it
Taking printed images to an appointment
A PDF prints the same everywhere, unlike a folder of images.
Attaching a scan to an insurance claim
Claims systems accept PDF; almost none accept DICOM.
Sending an overview of a series
Four slices per page gives a reviewer context without a huge file.
Supported files
- Uncompressed DICOM (implicit and explicit VR, little and big endian)
- RLE lossless compression
- JPEG baseline and extended, decoded by your browser
- Files with a .dcm extension, and DICOM files with no extension at all
- ZIP archives containing a whole study or several series
Limitations
- Images inside the PDF are JPEG-compressed to keep the file a sensible size, so the same lossy caveat as JPG applies.
- JPEG Lossless, JPEG-LS, JPEG 2000 and deflated transfer syntaxes are not decoded — they need heavy codecs we deliberately do not ship. You will get a clear message instead of a blank screen.
- This is a technical tool. It does not read your scan, does not look for findings and does not produce any diagnosis.
- Very large studies of several hundred megabytes may be slow, because all the work happens on your own machine.
Privacy and security
Processed in your browser — nothing is uploaded
Your files never leave your device. Everything runs inside your browser using JavaScript — there is no upload, no server copy and no queue.
Because nothing is uploaded, there is nothing for us to store or delete. Closing the tab removes the files from memory.
We never put file names, patient identifiers or metadata values into analytics or logs. Product events only count how many files were opened.
If you later choose the paid AI explanation, that is a separate, explicit step: you decide which files to attach and nothing is sent until you confirm.
Frequently asked questions
How do I convert a DICOM to PDF?
Load the file here, choose how many images you want per page and download. Everything happens in your browser.
Can I put a whole series into one PDF?
Yes. Load the series and every image becomes a page, or shares a page if you pick the two or four-up layout.
Does the PDF contain patient data?
No. The images are rendered pixels and the document properties are set to neutral values. Text printed inside the image itself still shows.
Is the PDF good enough for a doctor?
For discussion and reference, usually. For anything requiring measurement or re-windowing, they will want the original DICOM.
