Convert PSB files online for free
The converter easily converts your PSB file to various formats - free and online. No Photoshop or extra software needed.
The converter also works in reverse, so you can convert other Raster Image formats to PSB with high quality output.
A .PSB (Photoshop Big) file is an extra-large raster image format created by Adobe Photoshop to handle projects that exceed the technical limitations of the standard PSD format. While PSD files are strictly capped at 2 GB in file size and 30,000 pixels in any dimension, .PSB files support massive images up to 4 exabytes (EB) and 300,000 pixels in width or height. This makes them essential for billboard graphics, high-resolution 3D texture maps, and complex compositing workflows that require preserving layers, channels, and high-dynamic-range (HDR) data.
However, the massive scale of .PSB files creates significant workflow bottlenecks. Their proprietary nature means they are incompatible with most standard image viewers, web browsers, and mobile devices. Sharing a multi-gigabyte file via email or standard cloud tools is often impossible without compression, and opening these files requires a workstation with significant RAM and Adobe Creative Cloud licensing. Users often find themselves locked out of their own content if they cancel their subscription or need to send a proof to a client who lacks professional design software.
To overcome these hurdles, conversion is often necessary:
Use Convert.Guru to open and convert your PSB 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 PSB converter.
