What is a PSD file and why do I need a viewer?

PSD (Photoshop Document) is Adobe Photoshop's native file format for saving layered images with editable text, vector shapes, effects, masks, and adjustment layers. PSD files preserve the complete design structure, making them essential for design workflows, client deliverables, and collaborative projects. While PSD files can only be edited in Photoshop (which requires an expensive Creative Cloud subscription), many people need to view PSD files without editing - clients reviewing mockups, developers inspecting design handoffs, managers previewing layouts. Our free online PSD viewer lets anyone open and view PSD files without installing Photoshop.

Are my PSD files safe and private?

Yes, absolutely. All PSD parsing, rendering, layer extraction, and metadata reading happens entirely in your browser using @webtoon/psd library with WebAssembly acceleration. Your design files never leave your device - there are no server uploads, database storage, cloud processing, or external API calls. Perfect for client work under NDA, confidential product designs, unreleased marketing materials, watermarked mockups, and proprietary creative assets that must remain private.

What's the difference between PSD and PSB formats?

PSD (Photoshop Document) is the standard format supporting documents up to 30,000 x 30,000 pixels and maximum file size of 2GB. PSB (Photoshop Big/Large Document Format) supports documents up to 300,000 x 300,000 pixels and files larger than 2GB - perfect for large-format prints, high-resolution posters, billboards, and multi-page designs. Both formats preserve layers, effects, and editability. Our viewer supports both PSD and PSB files with no size restrictions beyond browser memory limits.

Can I view individual layers or just the flattened image?

Both! The viewer displays the flattened composite image (how the complete design looks with all layers combined) and provides an interactive Layer Tree panel showing every layer, group, and nested structure. See layer names, visibility states, opacity settings, and blend modes. While you can't edit layers or export individual layers as separate files (this is a viewer, not an editor), you can explore the complete layer hierarchy to understand design structure.

What Photoshop versions are supported?

The viewer supports PSD files from Photoshop CS1 (version 8.0) through CC 2024+ and all versions in between (CS2, CS3, CS4, CS5, CS6, CC 2013-2024). Files created in older Photoshop versions (6.0, 7.0) are also supported. Modern Photoshop features like smart objects, adjustment layers, layer effects (shadows, glows), and blend modes are recognized, though some advanced effects may display as flattened in the composite view.

Are CMYK and Lab color mode PSD files supported?

The viewer fully supports RGB, Grayscale, and Bitmap color modes with accurate color rendering. CMYK (print) and Lab color mode files can be opened and viewed, but colors are converted to RGB for browser display, which may cause slight color shifts. For critical print work where exact CMYK values matter, use Photoshop with proper color management. For general viewing, mockup review, and design approval, our viewer works perfectly for all color modes.

What's the maximum file size I can upload?

The viewer supports PSD and PSB files up to 100MB. Most PSD files are smaller (5-50MB for typical designs), but large files with many high-resolution layers, smart objects, or extensive layer effects can exceed 100MB. If your file is larger, consider flattening some layers in Photoshop or saving a copy with reduced layer count specifically for viewing/sharing purposes.

Can I download the composite image from a PSD file?

Yes! Download the flattened composite image as a high-quality PNG file perfect for sharing with clients, inserting into presentations, uploading to websites, or using in documents. The PNG preserves transparency (if present) and maintains full resolution. Great for sharing designs with people who don't need the editable PSD file or for creating quick mockup presentations.
