Convert HD photo files (HDP) online for free
The converter easily converts your HDP photos to various formats - free and online. No Magix Samplitude or or other Audio software needed.
To convert other file formats to the "Audio Cache Data" file type, you need software like Magix Samplitude or a similar tool.
The .HDP extension commonly represents one of two entirely different formats: a Magix Audio Waveform Peak file or a Microsoft HD Photo image. In the audio engineering world, programs like Magix Samplitude, Sequoia, and Movie Edit Pro generate these files to store the visual representation (waveforms) of audio tracks. These files utilize the Resource Interchange File Format (RIFF) architecture but do not contain actual sound data. Because they are purely visual cache files, attempting to convert them to playable audio formats is impossible. Alternatively, .HDP stands for HD Photo, a proprietary high-dynamic-range raster image format developed by Microsoft (later standardized as JPEG XR).
Users frequently struggle with .HDP files. The audio peak files clutter project folders and cause confusion when users mistakenly think they are lost audio recordings. The HD Photo files suffer from severe incompatibility; they lack native support in modern web browsers, macOS, and Linux, and require specific tools or plugins to open in software like Adobe Photoshop.
If you have an HD Photo image, you must convert it for practical use. For web publishing, convert to WebP or JPG. For lossless archiving or editing, convert to TIFF or PNG. Drag and drop your file to analyze and convert it - free, online, and without installing software. convert.guru will instantly identify whether your file is an image or an audio cache and provide the exact conversion or extraction tools you need.
Use Convert.Guru to open and convert your HDP file.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HDP converter.
