Image Compressor

Evorenza Image Compressor is a free browser-based tool that reduces image file sizes while preserving visual clarity. Files are processed on your device and are never uploaded.

How to use Image Compressor in 3 simple steps

  1. Step 1: Drag and drop images into the compression area (JPG, PNG, WebP, SVG, BMP up to 500 MB).
  2. Step 2: Adjust the quality slider (e.g., 80% for high visual fidelity) and select your target export format.
  3. Step 3: Review side-by-side file size savings and download your optimized images individually or in a ZIP.

Is Evorenza Image Compressor safe for confidential files?

Yes, Evorenza Image Compressor is entirely safe for private photographs, identity documents, product mockups, and corporate graphics. Compression executes locally on your hardware with zero server uploads.

Your pictures are decoded and compressed inside your browser canvas context, meaning no third party ever gains access to your files.

How does Image Compressor work without uploading?

Images are loaded into an HTML5 Image element and painted to an off-screen HTML5 canvas element. The browser then encodes the canvas pixel buffer into your chosen format (WebP or JPEG) using native browser compression codecs at your specified quality level.

This client-side workflow operates entirely offline after the initial web bundle loads, delivering near-instant compression without network latency.

Is it really free?

Yes, Evorenza Image Compressor is 100% free with no image quantity caps, daily quotas, or watermarks.

All compression features, batch processing, and ZIP downloads are available to everyone without fees.

What file types and sizes are supported?

Supports JPG, PNG, WebP, BMP, and SVG files up to 500 MB each, with batch processing for up to 100 images at once.

You can convert formats during compression (e.g., PNG to WebP) for maximum byte savings on web assets.
