Source format

PFM

Portable Float Map (PFM) is an image file format designed for storing high-dynamic-range (HDR) images with floating-point pixel values. It's commonly used in computer graphics and scientific visualization for its ability to capture a wide range of light intensities without clipping. PFM files can be uncompressed or use simple run-length encoding. They store color information, typically in RGB or grayscale, with high precision, making them ideal for applications requiring accurate radiometric data.

Target format

NPY

NPY (NumPy array) is the binary file format used by the NumPy library in Python to store arrays. It's highly efficient for storing numerical data, including multi-dimensional arrays of floating-point numbers. NPY files contain the array data itself and metadata such as the data type, shape, and endianness. This format is fundamental for data science, machine learning, and scientific computing in Python, enabling fast loading and saving of complex datasets.

💡

Why Convert PFM → NPY?

Converting PFM to NPY is essential for data scientists and researchers working with high-dynamic-range imaging data within the Python ecosystem. PFM files, while excellent for storing raw HDR image data, are not natively handled by Python's primary numerical computing library, NumPy. By converting PFM to NPY, you transform the image data into a format that NumPy and associated libraries (like scikit-image, TensorFlow, or PyTorch) can readily import, process, and analyze. This makes PFM image data compatible with machine learning models, advanced image processing algorithms, and data visualization tools.

PFM vs NPY

PFM (Portable Float Map) and NPY (NumPy array) serve different primary purposes. PFM is an image file format optimized for storing high-dynamic-range, floating-point image data, often used in specialized graphics or imaging applications. Its strength lies in preserving precise radiometric information. NPY, on the other hand, is a generic binary file format for NumPy arrays, designed for efficient storage and retrieval of numerical data within Python. While PFM describes an image structure, NPY describes a numerical array's content and shape. Converting PFM to NPY bridges the gap, making sophisticated image data accessible for numerical analysis and machine learning in Python.

Frequently Asked Questions

How do I convert PFM to NPY?

To convert PFM to NPY, navigate to the Convert2.co PFM to NPY converter page. Click the 'Upload PFM File' button and select your PFM image file(s). Once uploaded, click the 'Convert to NPY' button. Your file will be processed, and you can then download the resulting NPY file.

Is the PFM to NPY conversion free?

Yes, Convert2.co offers free PFM to NPY conversion. You can convert your image files without any hidden costs or subscription fees.

What is the quality of NPY output?

The conversion from PFM to NPY aims to preserve the original image data's precision. Since PFM often stores floating-point data, the NPY output will represent this numerical data accurately, making it suitable for scientific and analytical purposes.

Can I convert multiple PFM files at once?

Our tool currently supports converting one PFM file at a time. For batch conversion needs, you may need to upload and convert each PFM file individually.
