What's the difference between lossy and lossless compression?

Lossy compression removes some image data to achieve smaller files, potentially causing quality loss. Lossless compression reduces size without any quality loss by finding more efficient ways to store the same data.

About Image Compression

Image compression reduces file sizes by removing redundant data or approximating pixel values. This makes images load faster on websites, take less storage space, and transfer quicker via email. Our tools use industry-standard algorithms including PNG optimization, JPEG quality adjustment, and modern WebP compression.

Lossy Compression

Reduce size up to 90% by removing some image data. Best for photos.

Lossless Compression

Preserve every pixel while reducing file size. Best for graphics.

Quality Control

Adjustable settings to balance size and quality for your needs.

Private & Secure

Most tools run in your browser. Files stay on your device.

Frequently Asked Questions

Lossy compression (used in JPG, WebP) removes some image data to achieve smaller files. You may notice quality loss at high compression. Lossless compression (used in PNG, SVG) reduces size without any quality loss by finding more efficient ways to store the same data.

For photos, use JPG for maximum compatibility or WebP for modern browsers with better compression. AVIF offers even better compression but has limited browser support. Use our JPG to WebP converter to upgrade your photos.

For logos and graphics, use PNG for raster images with transparency or SVG for scalable vector graphics. PNG preserves sharp edges and text perfectly. SVG is ideal for icons and illustrations that need to scale to any size.

Typical reductions: JPG can be reduced 60-80% with minimal quality loss. PNG often shrinks 30-70% depending on the image. GIF animations can be reduced 40-60%. Results vary based on image content and original optimization level.

Lossless compression (PNG, SVG) preserves 100% quality. Lossy compression (JPG, WebP) may show artifacts at high compression levels. Our tools let you preview results and adjust quality settings to find the right balance.
