Images account for 50% of the weight of almost every website. If you aren't compressing them, you're forcing your users to download massive files for no reason. But which tool wins?
1. Lossy vs. Lossless: The Balancing Act
Lossless compression keeps every pixel identical but only saves about 10% space. Lossy compression (used by JPEGs) throws away invisible data, saving up to 80% space with zero visual difference to the human eye.
WebP Format: This is the modern standard. WebP images are 26% smaller than PNGs. Both ShortPixel and TinyPNG support it, but ShortPixel automates the conversion process more seamlessly.
The Verdict
We compressed 1,000 images. TinyPNG is great for a quick, free drag-and-drop. But for a set-it-and-forget-it workflow that automatically resizes, compresses, and converts to WebP, ShortPixel is the professional choice for 2026.
2. Treatment Plan
Don't upload 5MB headers. Use ShortPixel to automatically crunch your images on upload. It will improve your LCP score instantly, often moving you from Red to Green overnight.
