How to Inspect .PSD Files Locally
- Drop Your .PSD File Above
Select or drag your
.psdfile into the interactive workspace at the top of this page. - In-Memory Binary Parsing
Your browser reads the file via the HTML5
FileReader/ArrayBufferAPI and mounts the photopea engine. - Inspect, Navigate & Export
Use the viewer toolbar to zoom, inspect layers/tables/3D geometry, or export to standard formats with zero server uploads.
What Is a .PSD (Photoshop Document) File?
PSD (Photoshop Document) and PSB (Photoshop Big, for dimensions up to 300,000 × 300,000 pixels and files over 2 GB) are Adobe Photoshop’s native layered raster and vector design containers. Unlike flat delivery formats such as JPEG or PNG, a `.psd` file preserves the complete non-destructive authoring state of a composition: individual pixel layers, Smart Objects, live typography layers, vector shape masks, adjustment layers (Curves, Levels, Hue/Saturation), blending modes, and ICC color profiles.
Binary Architecture, Header Structure & Client-Side Parsing
Every binary `.psd` file starts with the 4-byte ASCII signature `38 42 50 53` (`8BPS`), followed by a 2-byte version integer (`0x0001` for PSD with 32-bit length fields, or `0x0002` for PSB with 64-bit length fields), 6 reserved zero bytes, channel count (1 to 56), pixel height and width (32-bit big-endian), bit depth (`1`, `8`, `16`, or `32` bits per channel), and color mode (`1` Grayscale, `3` RGB, `4` CMYK, `9` Lab). The remainder of the file is structured into four sequential length-prefixed sections: (1) Color Mode Data, (2) Image Resources (`8BIM` blocks storing EXIF, XMP, ICC profiles, guides, and slice metadata), (3) Layer and Mask Information (the layer tree, blend keys like `norm`/`mult`/`scrn`, and per-channel RLE PackBits or ZIP-compressed pixel planes), and (4) the pre-composited Merged Image Data fallback. ViewAnyFile.app mounts the full Photopea engine in-browser to parse and edit every `8BPS` / `8BIM` structure locally.
Common .PSD Compatibility & Troubleshooting Guide
When a PSD file appears flattened or displays a warning in third-party viewers, the file was saved in Photoshop without "Maximize Compatibility" enabled—omitting the pre-composited Merged Image Data in Section 4—or relies on CMYK/Lab adjustment layers that naive viewers cannot blend. Because ViewAnyFile.app uses a complete layer-compositing engine rather than just reading the flattened thumbnail preview, you can toggle individual layers, edit live text layers, and export individual assets.
Why Engineers & Teams Use ViewAnyFile for .PSD Files
- Avoids Adobe Creative Cloud subscriptions ($59.99/month) just to inspect or export a client PSD
- Full interactive layer tree — toggle layer visibility, inspect blending modes, and edit text layers inline
- Supports 8-bit, 16-bit, and 32-bit RGB, CMYK, and Grayscale PSD and large PSB files
- One-click export to transparent PNG, JPG, WebP, SVG, or print-ready PDF directly in your browser
- 100% client-side execution — unreleased brand campaigns, UI mockups, and creative IP never leave your device
Common Production Workflows for .PSD Files
- Frontend developers inspecting layer dimensions, hex colors, and exporting PNG/SVG slices from designer handoffs
- Marketing managers editing text layers on social media templates without Photoshop installed
- Clients reviewing agency creative mockups, poster layouts, and photo retouching proofs in the browser
- Photographers previewing multi-layer retouched composites on laptops or tablets
- Converting layered PSD compositions into flattened PNG, JPEG, or PDF deliverables (/convert/psd-to-png)
- Inspecting Smart Objects, layer masks, and adjustment layers before print production

Frequently Asked Questions — .PSD Format Specification
Can I toggle individual layers and edit text inside a PSD file here?
Yes! Our PSD viewer integrates the full Photopea engine, allowing you to inspect the complete layer hierarchy, hide/show layers, edit text layers, and export individual slices or flattened images.
What is the difference between a .psd and a .psb file?
Standard `.psd` files use 32-bit length pointers, limiting them to 30,000 × 30,000 pixels and 2 GB. `.psb` (Photoshop Big, version `0x0002` in the `8BPS` header) uses 64-bit length fields to support canvases up to 300,000 × 300,000 pixels. Both are supported.
Does the viewer support CMYK PSD files intended for print?
Yes. CMYK (`colorMode = 4`), RGB, Grayscale, and Lab PSD files are decoded and color-managed in your browser.
Can I convert a PSD file to PNG or PDF without opening the full editor?
Yes. You can export directly from the viewer or use our dedicated PSD to PNG (/convert/psd-to-png) and PSD to PDF (/convert/psd-to-pdf) converters.
