PSB to SIXEL Converter
Processing entirely on your device — large files may take a moment.
Photoshop Large Document and DEC SIXEL Graphics exist for different jobs: 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 an image to SIXEL to preview it inside a terminal session.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 SIXEL format
The DEC SIXEL Graphics coder of the ImageMagick set — the terminal-graphics format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+ Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
! Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
Why convert PSB to SIXEL?
Think of it as moving your file to the container that fits the job. Very large files SIXEL works differently: Written natively by ImageMagick 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 SIXEL 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 SIXEL?
No — SIXEL 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.
Can I convert several PSB files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
