How to Compress Images Without Uploading Them
Compress JPG, PNG, and WebP images directly in your browser without uploading them to any server.
Image compression is a common task for web developers, photographers, and content creators. But popular tools like TinyPNG and Squoosh upload your images to their servers. Here's how to compress images locally.
Local Image Compression: How It Works
Canvas API
Our image compressor draws your image onto an HTML5 canvas and exports it using canvas.toBlob() with adjustable quality settings.
Quality Control
Choose from High (95%), Standard (80%), or Compressed (60%) quality. Preview size reduction percentage for each image.
Batch Compression
Select multiple images and compress them all at once. Download individual files or all compressed images as a ZIP archive.
Format Flexibility
Our compressor supports JPG, PNG, WebP, GIF, BMP, and more. Convert between formats while compressing for additional size reduction.
