How to Convert Images for Medical Records
Medical records systems, patient portals, and insurance claim forms each have specific image format requirements. Whether you are uploading wound photos for telehealth, attaching lab results to your patient portal, or submitting images for an insurance claim, the file format matters. Upload the wrong format and the system rejects it. Upload an unnecessarily large file and it may time out or fail silently.
Privacy is especially critical with medical images. Uploading personal health photos to a random online converter means your medical images pass through someone else's server. For HIPAA-sensitive content, browser-based conversion that never leaves your device is the only approach that maintains patient privacy.
This guide covers the format requirements for common medical record systems and explains how to convert images while keeping them completely private.
Step-by-Step Instructions
- Identify the Required Format
Check your medical portal or insurance form for accepted file types. Most patient portals accept JPG and PNG. Insurance claim systems often accept JPG, PNG, and TIFF. Some older hospital systems only accept TIFF for radiology and pathology images. If the upload form does not specify, JPG is the safest default for photographic medical images.
- Convert to the Accepted Format
If your image is in a format the system does not accept (HEIC from your iPhone, WebP from a screenshot, or BMP from a scanner), convert it to JPG or PNG. Use JPG at quality 90 or higher for photographs to preserve diagnostic detail. Use PNG for screenshots of documents, lab results, or anything with text that needs to remain sharp.
- Check Resolution and File Size Limits
Most patient portals limit uploads to 5MB or 10MB per file. Medical photos from modern phones can be 5 to 15MB each. If your file exceeds the limit, reducing JPG quality from 95 to 85 typically cuts the file size by 40 to 60 percent with no visible quality loss. Do not reduce resolution below 1000 pixels on the longest side, as medical images may need to be zoomed in for examination.
- Remove EXIF Data If Needed
Phone photos contain EXIF metadata including GPS location, device information, and timestamps. For medical images, you may want to keep the timestamp (documenting when a condition was photographed) but remove the GPS data. Some conversion tools strip EXIF automatically. Check your converted file's properties to verify what metadata was retained.
- Upload and Verify
After converting, upload the image to the medical portal or attach it to your message. Most systems show a preview after upload. Verify that the image is clear, properly oriented, and that any text (lab results, prescriptions) is legible. If the system rejects the file, check the error message for specific format or size requirements you may have missed.
Common Medical Image Scenarios
Telehealth wound documentation is the most common medical image conversion need. Patients photograph wounds, rashes, or surgical sites on their phones and upload them to their patient portal for remote monitoring. These photos are typically HEIC (iPhone) or JPG and may need conversion to meet the portal's requirements.
Insurance claim attachments are another frequent use case. You may need to photograph a prescription, a medical bill, or damage documentation and submit it digitally. These images need to be clear enough to read all text while meeting the insurer's file format and size restrictions. Scanned documents from older scanners may be in BMP or TIFF format that needs conversion to JPG or PNG for online submission.
- Telehealth photos: Convert HEIC to JPG at quality 90+
- Insurance claims: JPG or PNG, typically under 5MB per file
- Scanned prescriptions: Convert to PNG for text clarity
- Lab results screenshots: PNG preserves text sharpness
- Radiology images: TIFF for lossless archival quality
Privacy and HIPAA Considerations
Medical images are protected health information under HIPAA. When you upload a wound photo or lab result to an online converter that processes files on a server, that server briefly has access to your protected health information. Most free online converters do not have HIPAA Business Associate Agreements and are not compliant with medical privacy regulations.
Browser-based conversion eliminates this concern entirely. When the conversion happens in your browser using local processing, the image never leaves your device. No server ever sees your medical images. This is the only conversion approach that maintains full HIPAA compliance for patient-initiated image conversion.

imageconvert.co converts images entirely in your browser. Your medical photos, lab results, and health documents never leave your device. No upload, no server processing, no privacy risk. Convert between JPG, PNG, TIFF, and other formats instantly while keeping your protected health information completely private.
Frequently Asked Questions
What image format do medical portals accept?
Most patient portals and medical record systems accept JPG (JPEG) and PNG. Some also accept TIFF and PDF. JPG is the most universally accepted format. If your portal does not specify, convert to JPG at quality 90 or higher.
Is it safe to use online converters for medical images?
Most online converters upload your files to a server for processing, which means your medical images pass through third-party infrastructure. For non-sensitive images this is fine, but for medical photos and health documents, use a browser-based converter like imageconvert.co that processes everything locally on your device.
How do I reduce the file size of a medical photo?
Convert to JPG and reduce the quality setting. Going from quality 95 to quality 85 typically reduces file size by 40 to 60 percent with minimal visible difference. Avoid reducing below quality 80 for medical images, as diagnostic details may be lost. If the file is still too large, you may need to reduce the image resolution.
Should I keep EXIF metadata on medical photos?
It depends on the use case. For wound documentation and telehealth, the timestamp metadata is medically relevant (it documents when the photo was taken). GPS location data is typically not needed and can be a privacy concern. If you are unsure, ask your healthcare provider what metadata they need.
