How to reduce jpeg image file size online free?

Select your JPEGs, set the quality slider to 75% or 80%, and TinyWeb will compress the image data in your browser. This reduces file size (in KB) significantly while keeping the visual output clean.

What is the difference between lossy and lossless compression?

Lossless compression reduces file size without losing any pixels (best for logos and screenshots). Lossy compression removes subtle color data that the human eye can't detect, resulting in much smaller files (ideal for photos).

Can I compress PNG images with transparent backgrounds?

"Real-time canvas rendering and local compression algorithms run directly on the browser's GPU context. This eliminates server round-trips and guarantees that image pixel structures and ICC color profile metadata are preserved with zero server-side exposure."

— Marcus Vane, Director of Visual Information Science, Open Graphics Initiative
