Image compression reduces file size while maintaining visual quality as much as possible. Image file sizes matter for everyday tasks like website speed optimization, email attachments, and social media uploads.
This online image compressor supports 3 output formats: JPEG, WebP, and PNG, with a quality slider for precise compression control. All processing happens in your browser, so images are never sent to any server.
Choose between JPEG (best for photos), WebP (smallest size), or PNG (preserves transparency) based on your needs.
Directly compare original and compressed images with a slider to visually verify quality differences.
Automatically warns when converting transparent PNGs to JPEG to prevent unintended data loss.
Simply drag images to upload and compress multiple images at once.
Reduce image sizes for blogs, online stores, and portfolios to improve page loading speed.

With 80%+ quality setting, the difference is barely noticeable. You get much smaller files while maintaining clean images.
JPEG is most efficient for photos, WebP offers the smallest file sizes, and PNG is best for logos or icons that need transparency.
PNG and WebP preserve transparency. Converting to JPEG replaces transparent areas with white background, and a warning is displayed.
