PSB to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
Photoshop Large Document and Gzipped TAR Archive 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. TAR.GZ is what open-source projects and Linux servers expect to receive.
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.
How PSB compares to TAR.GZ
| PSB | TAR.GZ | |
|---|---|---|
| Compression | Lossless (RLE/ZIP layers) | gzip (DEFLATE) |
| Best for | Design source files | Source releases and backups |

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 TAR.GZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
!Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)

Frequently asked questions
Is this PSB to TAR.GZ 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 TAR.GZ?
No — TAR.GZ 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.
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.
Will transparent areas survive the conversion to TAR.GZ?
Transparency is kept whenever TAR.GZ 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.
