About img.awajis

img.awajis is a collection of free image processing tools that run entirely in your browser. Your files are never uploaded to any server — all compression, conversion, and editing happens locally using WebAssembly technology.

How It Works

When you drop an image into img.awajis, it's decoded and processed using industry-standard codecs (MozJPEG, libwebp, oxipng) compiled to WebAssembly. This gives you near-native processing speed without any server infrastructure. Your browser does all the work.

Privacy First

We built img.awajis because we believe image processing shouldn't require uploading your files to a stranger's server. With img.awajis:

  • Zero files are uploaded — ever
  • No data is collected about your images
  • Works offline once loaded
  • No account or sign-up required

Technology

img.awajis is built with SvelteKit and uses WebAssembly codecs from the jSquash project (derived from Google's Squoosh). The codecs include:

  • MozJPEG — Mozilla's optimized JPEG encoder
  • oxipng — Rust-based PNG optimizer
  • libwebp — Google's WebP encoder/decoder
