PSD Viewer for Mac
Need to open a .psd file on your Mac but don't have Photoshop? PeekPSD runs entirely in your browser — Safari, Chrome, or Firefox. Drop a PSD file and instantly see every layer, text block, font, and color. No app to install, no files uploaded anywhere.
Why PeekPSD works great on Mac
Safari optimized
PeekPSD uses Web Workers and OffscreenCanvas, both well-supported in Safari 17+. Files process entirely on-device with Apple Silicon acceleration.
No Homebrew, no dmg
Skip downloading apps. Open peekpsd.com in any browser and start inspecting PSD files immediately.
Retina ready
The canvas viewport renders at your display's native DPI, so layer detail is crisp on 5K iMac and MacBook Pro screens.
Works offline
PeekPSD is a PWA. Visit once, and it works even when your Mac is offline — perfect for coffee-shop design reviews.
macOS Preview can't show layers
Apple's built-in Preview app can open PSD files, but it only renders the flattened composite. You can't see individual layers, read embedded text, or check which fonts were used. PeekPSD gives you the full layer tree — groups, masks, blend modes, opacity values, and smart objects — all without touching Terminal or installing Xcode tools.
Designers, project managers, and developers who receive PSD files from clients can review them in seconds. Export individual layers as PNG, download the composite as JPG or WebP, or generate a PDF for print.
FAQ
Does it work on Apple Silicon Macs?
Yes. PeekPSD runs in your browser, which is already optimized for M1/M2/M3/M4 chips. Large PSD files process faster on Apple Silicon compared to Intel Macs.
Is my file uploaded to a server?
No. All processing happens locally in your browser using Web Workers. Your PSD file never leaves your Mac.
Can I install PeekPSD as a Mac app?
Yes — PeekPSD is a Progressive Web App. In Safari, go to File → Add to Dock. In Chrome, click the install icon in the address bar. It then works like a native Mac app.
