About Image Compressor

Image Compressor is a free, fast, and privacy-focused online tool that helps you reduce image file sizes without sacrificing quality.

What We Offer

Image Compressor provides a suite of free online image processing tools:

Image Compression — Reduce JPEG, PNG, and WebP file sizes by up to 80% while maintaining visual quality.
Image Resizing — Change image dimensions to fit your specific requirements.
Format Conversion — Convert images between JPEG, PNG, and WebP formats.

All tools are completely free with no usage limits, no registration required, and no watermarks added.

How It Works

Image Compressor uses modern web technologies to process images entirely within your browser:

Canvas API — When you upload an image, it is drawn onto an HTML5 Canvas element. The Canvas API then encodes the image with your chosen quality settings, producing a compressed version.
Compressor.js — We use the open-source Compressor.js library, which wraps the Canvas API and provides fine-grained control over compression parameters including quality, dimensions, EXIF handling, and format conversion.
Vue.js — The user interface is built with Vue.js, providing a responsive and interactive experience for adjusting compression options and previewing results in real-time.

The entire process happens in your browser's JavaScript engine. No image data is ever transmitted to any server.

100% Browser-Based Processing

Unlike many online image tools, Image Compressor does not upload your images to a remote server for processing. Everything happens locally in your browser:

Your images never leave your device.
No server-side storage of your files.
No third-party access to your image data.
All processing is done using standard web APIs supported by modern browsers.

This approach ensures maximum privacy and speed — there is no waiting for server uploads or downloads.

Privacy Protection

Your privacy is our top priority. Here is how we protect it:

No image uploads — Images are processed entirely in your browser using JavaScript and the Canvas API.
No data collection — We do not collect, store, or analyze any images you process.
No tracking of image content — We have no ability to see, access, or share your images.
Minimal analytics — We may use standard web analytics to understand overall site traffic, but this never includes image data.

For more details, please read our Privacy Policy.

Supported Formats

Our tools support the most common image formats used on the web:

JPEG/JPG — Best for photographs and complex images with many colors.
PNG — Best for images requiring transparency or with text/sharp edges.
WebP — A modern format offering superior compression for web use.
GIF — Supported for compression (static frames).

Open Source

Image Compressor is built on top of open-source technologies. The core compression engine uses Compressor.js, an open-source JavaScript image compression library.
