PSB to APK Converter
Processing entirely on your device — large files may take a moment.
Photoshop Large Document and Android Package 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. Repack an APK as ZIP to inspect its manifest and assets (not for reinstalling).
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How PSB compares to APK

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 APK format
An APK is Android’s install package: a ZIP holding AndroidManifest.xml, compiled DEX bytecode, native libraries and assets. Unpacking one is the standard first step of security review, compatibility checks and asset recovery.
One honest limit: unpacking is inspection, not installation — a repacked ZIP cannot be installed back onto a phone, and the page says so.
+Strengths
- ✓Everything an Android app ships
- ✓ZIP-based, easy to unpack
- ✓Manifest readable as XML
!Limitations
- −DEX bytecode is not human source
- −Repack cannot reinstall
Why convert PSB to APK?
Converting makes sense where the strengths of APK meet what PSB cannot give you. Everything an Android app ships Meanwhile Very large files One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PSB to APK 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 APK?
No — APK 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 APK?
Transparency is kept whenever APK 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.
