Why we built this tool

We noticed most image compressors upload files to servers. Since privacy is our core principle, we built this tool to process everything locally using Canvas API and WebAssembly.

About QR Código Generador: what you should know

Photographers and hobbyists sharing work online. Before uploading to a gallery, social feed, or portfolio, optimize the file so it loads fast for visitors while still looking sharp on high-resolution screens.

Key features

  • One-Click Download — When you are happy with the result, download the processed image in one click. No watermarks, no sign-up walls, no forced account creation.
  • Direct File Upload — Drag and drop or select an image from your device. The tool supports common formats and gives you a live preview before any processing happens.
  • Local Processing Only — Your image never leaves your browser. Even photos with location EXIF data are processed on-device, protecting your privacy.

Common use cases

  • Reducing Email Attachment Size — Email clients and servers have attachment limits. Compress or convert an image so it fits in the message without losing visible quality.
  • Standardizing a Batch of Photos — When photos come from different cameras and phones, make them consistent — same format, same orientation — before adding them to a gallery or document.
