Frequently asked questions
Is the PSB to MRW converter free?
Yes. This free online converter has no limits and no watermarks.
Are my files uploaded to a server?
No. All conversion happens locally in your browser, so your images never leave your device.
Can I convert multiple PSB files at once?
Absolutely. You can drop many files and convert them all in one go — free and private.
Is PSB to MRW processed on my device?
Yes. XConverters handles files locally in the browser and does not transfer them to our servers.
Will MRW reduce PSB quality?
This MRW path keeps pixel data intact depending on your settings.
Does transparency from PSB carry into MRW?
No. MRW does not preserve alpha the same way; transparent areas flatten to a solid backdrop.
Do I need software installed for PSB to MRW?
No. Open the tool in a modern browser, pick PSB, and download MRW after processing.
How large can my PSB file be?
Limits depend on device RAM and the browser. Test one large file before converting a full batch.
What this conversion does
This path turns PSB (.psb) files into MRW (.mrw) inside your browser. XConverters reads pixels locally and re-encodes them in the target format without sending your file elsewhere.
MRW output is lossless and fits uncompressed camera originals before editing.
When to use it
You need MRW for uncompressed camera originals before editing while the source is PSB.
Solid backgrounds are fine and you do not need alpha in MRW.
You want an instant MRW preview before sharing or publishing.
Advantages
Convert PSB → MRW locally without waiting in a remote queue.
MRW keeps fine detail for print and archival use.
Batch a handful of PSB files with the same settings.
Limitations
Transparency in PSB becomes a flat background in MRW.
Very large PSB files can exhaust browser memory before conversion finishes.
Quality considerations
Avoid re-saving PSB through multiple lossy formats.
Compare size and sharpness before replacing the original.
Keep the original PSB copy before committing to MRW.
Best practices
Name outputs with the correct .mrw extension to avoid viewer errors.
Add a white or brand-colored backdrop before MRW when transparency is not needed.
Use identical quality settings across a batch for consistent results.
Privacy
Your files never leave your device when you use PSB → MRW conversion on XConverters. No account is required and we do not retain copies of the images or documents you process.
That local-first model suits personal photos, work documents, and sensitive RAW files you prefer to keep offline.
Browser processing
XConverters runs PSB → MRW conversion entirely inside your browser. Files are decoded locally, pixel data flows through Canvas or WebAssembly where needed, and the finished file is encoded on your device.
No remote copy is created during processing. Temporary data clears when you close the tab or refresh unless you download the result yourself.
Common mistakes
Assuming MRW is always smaller than PSB — lossless PNG/TIFF output can be larger.
Forgetting that MRW removes PSB transparency.
Re-converting the same PSB through MRW while lowering quality each time.
