Convert large Photoshop documents (PSB) online for free
The converter easily converts your PSB large documents to various formats - free and online. No Adobe Photoshop or other Raster Image software needed.
The converter also works in reverse, so you can convert other "Large Document Format" formats to PSB without using software like Adobe Photoshop or a similar tool.
.PSB is a proprietary raster image format created by Adobe Systems. It is designed specifically for images larger than 30,000 by 30,000 pixels or files exceeding the 2 GB limit of standard PSD files. It is heavily used by professional photographers, matte painters, and billboard designers.
You can open and edit these files natively using Adobe Photoshop. Some alternative programs like Affinity Photo can also handle them. In rare cases, the .PSB extension is used for game data archives (CatSystem2 engine), E-mote character animations, or Siemens SIMATIC HMI panel backups.
The main disadvantage of the .PSB format is extreme incompatibility. Web browsers, default operating system viewers, and most standard image software cannot open them. Because they hold massive resolutions and multiple uncompressed layers, they consume huge amounts of RAM and disk space. Sharing a raw .PSB file with a client for review is practically impossible without forcing them to buy expensive software.
Drop your file here to analyze and convert it securely right in your browser. For client previews or web use, convert to JPG or WebP (note that layers will be flattened). For high-quality printing or archiving with better compatibility, convert to TIFF or PDF. If you need standard layered editing and your image is under 2 GB, you can shrink the canvas and convert it back to PSD.

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.
