Convert PSB to HDR
Fast, free, and secure PSB to HDR conversion. No registration required.
Whether you have one psb file or fifty, converting them all to hdr takes just seconds with Xonvert's browser-based engine. Your source file uses Photoshop Big encoding (standard since 2003). The output will use HDR Image encoding (available since 1985). This particular format pair is popular among photographers and designers who need reliable, fast conversion. This conversion is instant for most file sizes. Large files may take a few extra seconds of processing.
Advantages of HDR over PSB
There are strong reasons to convert PSB to HDR:
Industry standard: In many image workflows, HDR Image has become the go-to format, making this conversion a frequent necessity.
API and automation: Many automated workflows and APIs expect HDR Image as input, making this conversion necessary for programmatic processing.
Editing flexibility: HDR Image files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens HDR Image natively, reducing compatibility friction.
Smaller file size: Efficient compression in HDR Image often produces significantly smaller files than Photoshop Big, saving storage space and bandwidth.

PSB to HDR: Quality Comparison
File size can exceed 4GB (PSD limited to 2GB) When this data is re-encoded into HDR Image, Used for environment maps and Image-Based Lighting (IBL) Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. HDR Image preserves all data losslessly, so output size depends on the content's inherent compressibility.
Converting between image formats is one of the most common file operations. When moving from Photoshop Big to HDR Image, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
The PSB to HDR conversion applies format-appropriate algorithms to ensure maximum data fidelity. File size can exceed 4GB (PSD limited to 2GB)
