Image Compressor

Compress and optimize image file size online free. Reduce image size while maintaining visual quality.

Shrink image file sizes while preserving visual quality for faster websites and smaller email attachments. This free browser tool compresses photos and graphics locally, improving load times and Core Web Vitals while dialing in quality settings per image type so pages feel snappy without looking blurry.

Why Compression Matters

Heavy images slow page loads, hurt search rankings, and frustrate mobile users on limited data. Email systems reject oversized attachments outright. Compressing images is often the single fastest performance win available to a website, requiring no redesign or code changes beyond swapping files.

Set up a repeatable workflow with named quality presets for photos, screenshots, and icons so teammates apply consistent settings without guessing each time. Compress before uploading to your media library rather than after, and spot-check critical images on a slow connection to confirm visual quality holds up under real-world conditions.

Choosing Quality Settings

Photographs tolerate moderate compression well; aim for quality settings around 75 to 85 for the best balance. Screenshots and flat graphics prefer higher settings or lossless formats to keep text crisp. Review each result at 100 percent zoom before committing to a full batch.

  • Photos: moderate quality, larger savings
  • Screenshots and logos: high quality to preserve edges
  • Always compare before and after side by side

Resize Before Compressing

Serving a 4000-pixel photo in a 600-pixel slot wastes bytes. Downscale images to their display size before compression, including 2x variants for retina screens. Dimension reduction often saves more than quality tuning alone, especially for full-width hero images, background banners, and gallery thumbnails rendered at fixed widths.

Formats Worth Knowing

JPEG suits photographs, PNG fits transparency and sharp edges, and modern formats such as WebP or AVIF deliver better compression ratios where supported. Choose format based on content, and provide fallbacks if your audience includes older browsers. Keep original masters uncompressed so future format changes never require re-editing from degraded copies.

A Practical Workflow

Export or capture at final dimensions, compress, test on a throttled connection, and deploy. Keep uncompressed masters in your asset library for future re-exports. Because compression runs locally, product photography and private documents never leave your machine.
