MEF to PDF Converter

Convert MEF files to PDF. Batch, free and without uploading.

This tool converts MEF files to PDF. MEF is the RAW format of Mamiya cameras. It keeps unprocessed sensor data; conversion uses the camera’s white balance and colour settings.

PDF is a document format that looks the same on every device; fonts, images and layout are kept exactly. Each MEF file becomes its own PDF. To combine several images into one PDF, use the "JPG to PDF" tool. RAW files are large, so each photo may take a few seconds.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your MEF files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Optionally set a maximum width and height.
3. Press "Convert" and download the PDF files one by one or as a ZIP.

Frequently asked questions

Will converting to PDF reduce quality?

No. PDF is lossless; the image in your MEF is carried over as it is.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your MEF files are converted to PDF inside your browser and never sent to a server.
