DICOM to TIFF Converter

Convert DICOM medical images (.dcm) — CT, MRI, X-ray, ultrasound — to TIFF. Lossless, private and metadata-free: only the image pixels are exported, never patient data.

Your privacy, by design

Every conversion removes DICOM metadata by default. No configuration is required.

A DICOM header carries Protected Health Information — patient name, ID, birth date, study dates, physician and institution. This converter exports only the image pixels, so every one of those tags is dropped automatically. The one exception is text a scanner may have burned directly into the picture, which is part of the image itself and cannot be removed automatically.

Archive a .dcm scan as a lossless TIFF

DICOM is the format medical scanners use, and it can rarely be opened outside specialist viewers. Converting to TIFF gives you a lossless, print-ready copy of the scan for documentation or archiving — while the sensitive metadata stays behind. Everything is processed in memory and deleted the instant your download is ready.

About Converting DICOM to TIFF

DICOM is the international standard that medical scanners use to store and exchange images — CT, MRI, X-ray, ultrasound and more. A .dcm file wraps the picture together with a large header of patient and study information, which is why it can rarely be opened outside specialist viewers. When you need to move away from DICOM, the usual reason is simple: cannot be opened by ordinary image viewers.

Converting your DICOM image to TIFF solves that. TIFF is a flexible, high-fidelity raster format favored in publishing, photography and scanning. It supports lossless compression, layers and multiple pages in a single file. In practice you gain lossless, print-quality output and multi-page and layer support. PrivConvert runs the whole DICOM-to-TIFF conversion in server memory and deletes your file the instant the TIFF is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need lossless, print-quality output
  • You need multi-page and layer support
  • You need industry standard for scanning and prepress
  • Sharing a DICOM image with someone whose software expects TIFF

Tips for best results

  • TIFF preserves quality exactly, so the conversion from DICOM will not introduce any new compression artifacts.
  • For the smallest possible TIFF without visible quality loss, start from the highest-quality DICOM you have.
  • Files up to 250 MB are supported, and you can batch-convert several DICOM files at once; each is processed privately and deleted immediately.

Frequently Asked Questions

Is my patient information removed?
Yes — by default. We read only the image pixels and re-encode them, so every DICOM tag (patient name, ID, birth date, study dates, referring physician, institution and all other metadata) is discarded. The TIFF we hand back contains no header data at all.
Is there anything you can NOT remove?
One thing: text that the scanner has 'burned into' the picture itself. Some machines paint the patient's name or ID directly onto the pixels. That is part of the image, not the metadata, so no converter can detect or erase it automatically. If your scan has burned-in text, crop it out before sharing.
Why TIFF for medical images?
TIFF is a lossless, print-quality format widely used in publishing and archiving. It reproduces the scan exactly with no compression artifacts, which makes it a good choice for documentation, printing and long-term storage.
Which DICOM files are supported?
Standard single- and multi-frame images from CT, MRI, X-ray, ultrasound and similar modalities, including compressed variants (JPEG, JPEG 2000, RLE). We apply the file's stored window/level so the image looks the way a viewer would show it. For multi-frame files, the first frame is exported.
Is this tool really free and private?
Yes. It is completely free, with no watermarks and no sign-up. Every conversion runs in an isolated, in-memory process — your file never touches the disk, is never stored or shared, and is wiped from memory the moment your download is ready.
Can hospitals or clinics use this converter?
The converter is designed to process files entirely in memory and removes DICOM metadata from the exported image by default. Organizations should always ensure that using any online service complies with their internal policies and applicable privacy regulations.
