DICOM to PDF converter online — private, no upload
Drop a .dcm file or a whole study folder and turn it into a PDF: one slice or the full series report with a cover page. Patient data never leaves your device — parsing and PDF generation both run locally in your browser. Viewing is free; exports use a one-time license.

How it works
Drop a study folder
A whole CT/MR study at once — files are parsed on the spot by JavaScript in this tab and grouped into series, in the scanner's own slice order. Nothing is uploaded, ever.
Find the right slice
Scroll the mouse wheel to step through slices and drag on the image to adjust window/level (contrast) — exports capture exactly what you see. Corner annotations show slice position and window values.
Export the PDF
"PDF slice" gives you the current slice as a one-page PDF. "PDF report" merges the whole series — cover page with the study metadata, one page per slice — into a single document you can archive or attach. Exports unlock with the one-time license.
Simple pricing
The viewer is free and unlimited. A one-time $9.99 unlocks every export — PNG, JPG and PDF.

Frequently asked questions
How do I convert DICOM to PDF without installing software?
Right here: drop the .dcm file (or the whole study folder) onto the box above.
The images open instantly and viewing is free — scroll to the slice you need, adjust the
window, then click "PDF slice" for a one-page PDF, or "PDF report" to merge the whole series
into one document with a cover page. Exports use a one-time $9.99 lifetime license. No PACS
workstation, no account, no upload.
Is it safe to convert patient scans here?
Yes — by construction, which matters for patient data. The DICOM files are parsed and rendered entirely by JavaScript running in your browser, and the PDF is assembled locally too; no file bytes are ever transmitted. You can verify this yourself: open your browser's developer tools (Network tab), convert a file, and watch — nothing is sent anywhere. Details in the privacy policy.
What's the difference between "PDF slice" and "PDF report"?
"PDF slice" exports the slice currently on screen — exactly as you windowed it — as a single PDF page. "PDF report" walks the whole series: a cover page with the patient/study/series metadata, then one page per slice with window-value captions. Both are covered by the same one-time $9.99 lifetime license; viewing files on the page is free.
Can I adjust brightness/contrast before converting?
Yes. Drag on the image with the left mouse button: horizontal movement changes the window width (contrast), vertical movement changes the window center (brightness) — the standard DICOM window/level gesture. The buttons above the image jump to the standard presets (Soft tissue, Lung, Bone, Brain). Single-slice exports (PNG, JPG, PDF) capture exactly what you see; the full report uses each file's stored default window for consistency across the series.
Why can't some files be converted?
Two cases are called out explicitly instead of failing silently: the file stores its pixels compressed (JPEG or RLE transfer syntax — common in hospital PACS exports), or it uses a YBR color space. Those slices are skipped in a report (the rest still export), and the viewer tells you exactly why. Uncompressed grayscale, RGB and palette-color images convert directly.
Can I use the PDF for diagnosis?
No. The PDF is a convenience rendering for review, archiving and documentation. It is not a medical device output and is not intended for diagnostic use — always verify against the original DICOM files on a regulated diagnostic workstation.
I already paid but lost my license key — what do I do?
Your key is shown on your Gumroad receipt, emailed to you right after checkout — search your inbox for "Gumroad" and open the receipt to copy it. Then click "Enter license key" in the top navigation to re-activate PDF report export.
