PAM (Portable Arbitrary Map) is an extended Netpbm format supporting any number of channels.
OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic. It is widely used in visual effects and computer graphics.
FreeFileConvert uses tuned encoding for PAM to EXR conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PAM files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized EXR results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent EXR audio with dependable progress tracking.
PAM files can contain grayscale, RGB, or RGBA data with 1 to 65535 maximum value.
EXR supports multiple channels, 16-bit and 32-bit floating-point pixels, lossless and lossy compression, and metadata storage.
Upload your image file in the PAM format from your device, Dropbox, or Google Drive.
