Topaz Gigapixel moved to a subscription model in 2024. Here’s how it compares to omnikitbolt for everyday upscaling.
| Feature | Topaz Gigapixel AI | omnikitbolt |
|---|---|---|
| Price | $99–199 one-time or $17–25/mo subscription | Free (5 upscales/day) — no credit card |
| Install required | Desktop app (Windows / Mac) | Browser only — nothing to install |
| Privacy | Local processing on your machine | 100% in-browser — images never leave your device |
| Upscale 2x / 4x | Yes | Yes |
| Signup needed | Yes (Topaz account required) | No — open and go |
| AI super-resolution | Yes — proprietary deep learning models | Yes — real ESRGAN neural network (browser-based) |
| Best for | Extreme detail recovery on degraded photos | Web, social media, product photos, everyday use |
Honest note: both use AI super-resolution. omnikitbolt runs a real ESRGAN neural network locally in your browser (fully private, no upload). Topaz’s proprietary models are larger and trained on billions of images, so they recover more detail on heavily degraded or very small sources. For web, social media and everyday photos the difference is negligible.

4x upscaling uses two sequential 2x passes for significantly sharper results than a single 4x jump.
Upscaled images are saved as lossless PNG to preserve every detail. No compression artifacts added.
Topaz Gigapixel AI is now part of Topaz Photo AI, which costs $199/year or roughly $17–25/month as a subscription. A legacy one-time license was previously available at $99, but new purchases require a subscription. omnikitbolt offers the same core upscaling (2x and 4x) completely free, directly in your browser — no install, no signup.
Yes. omnikitbolt uses a real ESRGAN neural network (the same class of AI model as Topaz) running directly in your browser — no installation or signup required. Free users get AI 2x upscaling. Upscayl (free, open-source desktop app) is another solid option for offline use.
omnikitbolt now uses ESRGAN — the same neural network architecture behind most AI upscalers including Topaz. For 2x super-resolution on everyday photos, results are very close. Topaz Gigapixel's proprietary models trained on billions of images can recover more detail on heavily degraded or very small sources. For thumbnails, product photos, social media, and everyday upscaling, omnikitbolt AI produces excellent results — and it's entirely free at 2x.
omnikitbolt runs a real ESRGAN (Enhanced Super-Resolution Generative Adversarial Network) model in your browser using TensorFlow.js. The model was trained to hallucinate realistic high-frequency detail — edges, textures, fine patterns — that simple interpolation cannot recover. It processes your image in overlapping patches to handle any size without running out of GPU memory. Everything runs locally in your browser; your images are never uploaded to any server.
Free users get AI 2x upscaling (e.g. 500x500 → 1000x1000). Pro users get AI 4x (e.g. 500x500 → 2000x2000) and can process images up to 2500px on the longest side with full AI. 4x is ideal for small thumbnails, icons, or print preparation where maximum enlargement is needed.
No — AI upscaling actively sharpens and reconstructs detail rather than blurring. ESRGAN is specifically trained to recover sharp edges and textures. The result is noticeably crisper than browser or Photoshop bicubic interpolation. For very degraded or noisy originals, the AI may occasionally introduce mild artifacts on extreme fine detail, but overall sharpness is substantially better than non-AI methods.
omnikitbolt supports all major image formats: JPEG/JPG, PNG, WebP, GIF, AVIF, and HEIC. The upscaled output is always PNG to preserve maximum quality without any lossy compression artifacts.
Yes! Free users get 5 upscales per day with images up to 1500px. Pro users ($9/month) get 100 upscales per day with no size limits, plus access to all 27 omnikitbolt tools with higher limits.
Topaz Gigapixel AI used to cost a one-time fee of $99. In 2024, Topaz Labs moved to a subscription model — Topaz Photo AI now costs $199/year or roughly $17–25/month. Many photographers and designers who simply need to upscale a photo for web or print don’t need enterprise-tier AI to do it.
omnikitbolt is a free browser-based alternative that handles the most common upscaling jobs: enlarging product photos, prepping images for print, making thumbnails sharper on Retina displays, and recovering old low-resolution images. Everything runs in your browser — your images never leave your device.
