About This Tool

Image Compressor is a free online tool that reduces the file size of your images directly in your browser. Supporting JPEG, PNG, and WebP formats, it allows you to adjust compression quality, resize dimensions, and convert between formats — all without uploading your images to any server. Large, unoptimized images are one of the biggest contributors to slow page load times, which negatively impact user experience, bounce rates, and SEO rankings. Whether you need to optimize images for your website, reduce file sizes for email attachments, or prepare photos for social media, this tool provides instant results while keeping your data completely private. The compression happens entirely client-side using the HTML5 Canvas API, ensuring your images never leave your device.

How to Use

  1. Set your desired compression quality using the slider (10-100%). Lower values produce smaller files with more compression artifacts.
  2. Optionally set a maximum width to resize large images. The height is automatically adjusted to maintain the aspect ratio.
  3. Choose your output format: JPEG for photos, PNG for graphics with transparency, or WebP for modern web optimization.
  4. Click the upload area or drag and drop your images. You can compress multiple images at once.
  5. Review the compression results showing original and compressed sizes, then download individual images or all at once.

Frequently Asked Questions

Yes, absolutely. All image compression happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. The tool works completely offline once loaded, ensuring maximum privacy for your sensitive images and photos.
This tool supports JPEG, PNG, WebP, GIF, BMP, and most other browser-compatible image formats as input. You can output compressed images in JPEG, PNG, or WebP format. JPEG is recommended for photographs, PNG for images requiring transparency, and WebP for the best compression ratio on modern websites.
The compression ratio depends on the original image and your quality settings. JPEG images can typically be reduced by 50-80% with minimal quality loss at 70-80% quality. WebP format often achieves 25-35% smaller files than equivalent JPEG images. PNG compression is lossless but generally produces larger files than JPEG for photographs.
Only if you set a maximum width. By default, the tool preserves the original dimensions. When you set a maximum width, the image is proportionally scaled down if it exceeds that width. The height is automatically calculated to maintain the original aspect ratio, so your images are never stretched or distorted.
