Smart Image Compressor — Smaller Files, Same Dimensions
Unlike a traditional image resizer, this tool compresses your images by re-encoding them with a better algorithm— keeping the exact same pixel dimensions. A 4000×3000px photo stays 4000×3000px, just with a dramatically smaller file size.
Why WebP is the Best Choice
WebP is a modern image format developed by Google. At the same visual quality, WebP files are typically 25–35% smaller than JPEG. All major browsers (Chrome, Firefox, Safari, Edge) support WebP. If your images are going on a website, convert to WebP and use JPEG as a fallback.
Understanding the Quality Slider
The quality slider controls how aggressively the image encoder discards imperceptible detail. 80% quality is usually indistinguishable from 100% but can be 3–5× smaller. For website thumbnails you can often go as low as 60–70% without users noticing.
- 80–100% — Near lossless. Use for printing or professional archiving.
- 60–80% — Recommended for websites and social media.
- 30–60% — Aggressive compression. Fine for previews and thumbnails.
- 1–30% — Maximum compression. Noticeable quality loss on photos.
