PSB to DDS Converter
Processing entirely on your device — large files may take a moment.
PSB ("Photoshop Big") is PSD's large-format sibling — the same layered structure, sized for documents beyond 30,000 pixels that plain PSD cannot hold. Convert a PNG or JPG into a DDS texture for game-engine imports, or back to PNG for inspection.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the PSB format
PSD is Adobe Photoshop's native document format and the source-of-truth file of the design industry. It keeps everything editable: layers with masks, adjustment layers, smart objects, layer effects and live text. The format is big-endian and only partially documented, but its ubiquity means libraries in every language can read the common parts.
Two practical gotchas define PSD life outside Photoshop. First, files are enormous — hundreds of megabytes is normal for layered work. Second, the flattened composite other apps display is only embedded when the file was saved with “Maximize Compatibility” enabled; without it, converters that read the composite will fail. Sharing to non-designers means exporting a JPG, PNG or PDF copy.
+ Strengths
- ✓Fully editable: layers, masks, effects and live text
- ✓The universal design source format
- ✓Smart objects allow non-destructive scaling and filters
! Limitations
- −Very large files
- −Full fidelity requires Photoshop or Creative Cloud apps
- −Composite preview may be missing without Maximize Compatibility
About the DDS format
DDS is the DirectDraw Surface texture format of DirectX game pipelines. This converter writes the uncompressed 32-bit BGRA variant — the universal fallback every engine's importer accepts before any compressed codec.
Mipmaps and block compression (BC1-7) are not written; the file is a flat full-resolution BGRA image with a classic DX header.
+ Strengths
- ✓Universal engine-import fallback
- ✓Lossless, full alpha channel
- ✓No codec negotiation needed
! Limitations
- −No mipmap chain written
- −Uncompressed = large files
- −BC compressed variants not written
Why convert PSB to DDS?
Think of it as moving your file to the container that fits the job. Very large files DDS works differently: Universal engine-import fallback If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this PSB to DDS converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting PSB to DDS?
No — DDS is a lossless format, so every pixel of the converted image matches your original PSB file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your PSB files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to DDS?
Transparency is kept whenever DDS actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
