AI Image Tools — Free & Private

AI-powered tools that run in your browser: remove backgrounds, extract text (OCR), upscale images, and vectorize photos. No upload, no API calls — everything stays on your device.

Remove Background

Remove backgrounds from photos automatically using AI. Free, instant, browser-based. No upload needed.

Extract Text (OCR)

Extract text from images using OCR. Supports 100+ languages. Free, instant, browser-based.

Upscale Image

Enlarge images 2x or 4x with intelligent upscaling and sharpening. Free, instant, browser-based.

Vectorize Image

Convert bitmap images to scalable SVG vectors. Trace edges and colors automatically. Free, browser-based.

AI That Runs in Your Browser

Unlike most AI image tools that send your photos to cloud servers for processing, Vizua's AI tools run entirely in your browser using modern browser technologies and JavaScript ML models. Your images never leave your device — complete privacy, even for sensitive photos.

Available AI Tools

  • Remove Background — Automatically detect and remove image backgrounds using an AI model. Perfect for product photos, profile pictures, and design work.
  • Extract Text (OCR) — Recognize and extract text from images using an advanced OCR engine. Supports 100+ languages. Great for digitizing documents, receipts, screenshots, and signs.
  • Upscale Image — Enlarge images 2x or 4x using smart resampling algorithms. Improve resolution for printing or display at larger sizes.
  • Vectorize Image — Convert raster images to SVG vector format using edge-detection algorithms. Ideal for logos, icons, and line art that need to scale infinitely.

How Client-Side AI Works

The background removal model (~40 MB) loads once and caches in your browser. Subsequent uses start instantly. OCR uses the OCR engine loaded from CDN with language-specific data files. Upscaling uses mathematical interpolation (smart resampling), and vectorization uses edge-detection tracing algorithms. All processing happens on your CPU/GPU — no server, no API, no usage limits.

Privacy Advantage

Cloud-based AI tools require uploading your images to remote servers. You can't verify what happens to your data. Vizua's approach is different: the AI model downloads to your browser, and all processing happens locally. Your photos of family, documents, ID cards, or sensitive materials never leave your device.
