Business Impact

The Commercial Value of
2K & 4K Imagery.

Visual excellence is directly correlated with user trust, brand authority, and digital conversion rates. PixelBoost bridges the gap between legacy assets and modern 4K displays without manual recreation.

Brand Authority

Enhance User Experience

Low-resolution artifacts undermine brand credibility. Upgrading asset fidelity to 4K ensures your product photography and digital interfaces look razor-sharp on ultra-high-definition screens.

Print Readiness

Legacy Asset Reclamation

Transform web-compressed graphics and legacy archives into pristine 2K and 4K print-ready media. Reconstruct missing pixel density for brochures and large-format displays.

E-Commerce

Maximize Conversions

Detailed visual context reduces buying friction. By eliminating pixelation from compressed source files, your storefront presents products with 4K clarity, reducing return rates.

Digital Media

Polished Digital Renders

Perfect for illustrations and game concepts. The neural network intelligently interprets edges, scaling digital art to 4K presentation while avoiding generic blurring.

Security Protocol

Why Local Processing
Trumps Cloud Platforms.

When you upload proprietary assets to cloud upscalers, your data enters an external server. PixelBoost operates on a completely local architecture — zero data leaves your device, ever.

Data Sovereignty

Zero Remote Footprint

Your assets are never sent to a third-party server, cloud bucket, or external API. The upscaling pipeline runs entirely inside your browser sandbox.

IP Protection

Strict Confidentiality

Unreleased prototypes and proprietary designs remain safe. If data doesn't travel, it cannot be intercepted.

Compliance

Regulation Friendly

Because no information leaves the user's device, PixelBoost natively aligns with data protection guidelines, eliminating complex compliance overhead.

Performance

No Server Bottlenecks

Cloud tools throttle based on subscription tiers. Local compute ensures an independent, predictable pipeline always ready to output high-resolution results.

Core Capabilities

Advanced Architecture.
Zero Friction.

Deployment

Edge Execution

The AI model caches to your device on first visit. Once loaded, the platform operates fully offline — no network dependency for subsequent runs.

Performance

GPU Acceleration

PixelBoost detects WebGPU capability and routes computation accordingly. On supported hardware, fp16 GPU inference dramatically outperforms CPU processing.

Multi-Pass

Iterative Super-Resolution

2K and 4K targets are reached through sequential ×2 passes. Each pass refines the previous output, producing results far superior to single-step interpolation.

Accessibility

No Friction, No Paywall

No registration, no usage caps, no watermarks. Full 2K and 4K parity on every single run — completely free, always.

Documentation

Frequently Asked
Questions.

What determines processing speed?

Speed depends entirely on local hardware. Systems with WebGPU support process tiles in parallel on the GPU, achieving results significantly faster than CPU-only paths. Tile size also affects throughput: larger tiles reduce total tile count but require more VRAM.

How many passes does 4K take?

PixelBoost calculates passes dynamically based on input size. Each pass doubles the resolution. A 500px image needs approximately 3 passes to reach 4K — the UI shows the estimated count before you process.

What AI model powers PixelBoost?

The Swin2SR-lightweight model — a compact, quantized (q4f16) Swin Transformer variant optimized for image super-resolution. It weighs under 8 MB and loads entirely in-browser via Transformers.js.

Is my data ever sent anywhere?

Never. All pixel data remains inside your browser's memory. The AI model is fetched from a CDN once and cached. After that, PixelBoost runs fully offline with zero external calls during processing.
