Image Compressor

Web performance studies consistently show that oversized images are the #1 contributor to slow page loads. A typical website with unoptimized images loads 3–5× slower than it could. For Nepali users on slower mobile connections, image optimization directly translates to better user experience and higher engagement.

Target file sizes for web use

- Hero images: ≤200KB - Product photos: ≤100KB - Thumbnails: ≤20KB - Icons: ≤5KB (better as SVG) - Blog post images: ≤150KB

Quality settings explained

JPG/WebP quality is set on a 0–100 scale. Quality 100 is (nearly) lossless. Quality 75–85 is the sweet spot — visually indistinguishable from 100 on most screens but 50–70% smaller. Below 60, compression artifacts become visible on fine details and sharp edges.

Lossy vs lossless

For photographs, lossy compression (JPG, WebP lossy) delivers the best file size reduction. For screenshots, diagrams, and UI graphics, lossless compression (PNG with oxipng optimization) preserves quality without introducing artifacts.

Batch compression

Upload multiple images and compress them all in one pass. The tool shows before/after sizes and total savings. Download all compressed images as a single ZIP file.
