Privacy Policy

Introduction

ImgTweak ("we", "our", or "us") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights regarding that information when you use our image tools at imgtweak.com.

By using ImgTweak, you agree to the practices described in this policy.

How Image Processing Works

Every tool on ImgTweak processes files entirely on your device using the following browser technologies:

• WebAssembly modules (MozJPEG, OxiPNG, libwebp, libavif, libjxl) for compression and format conversion
• Web Workers for CPU-intensive tasks such as SVG tracing, keeping your browser responsive during processing. Web Workers run in a separate thread on your device
• imagetracerjs (public domain) for raster-to-SVG vectorization on the PNG/JPG/WebP to SVG tools
• pdf-lib and pdfjs-dist for PDF creation and page extraction
• heic-to for HEIC decoding and utif2 for TIFF decoding
• icojs for ICO file handling and favicon generation
• Optional machine learning models for local OCR, background removal and facial landmark guide assistance. These assets load only when the related feature is used

These libraries do not send your image data to a processing server. Some tools download code, language data or model files when a feature is first used. After the required assets have loaded, image processing occurs on your device.
