How Does Our Image Compressor Work?

Reduce image file size in three simple steps — no account, no upload, no hassle.

1

Upload Your Image

Drag and drop or click to select any JPG, PNG, or WebP image from your device. Your file is loaded directly into your browser's memory — it never touches a server.

2

Choose Quality & Format

Drag the quality slider to find your ideal balance between file size and visual quality. The real-time size estimate updates instantly so you see exactly what you'll get.

3

Compress & Download

The Canvas API renders your chosen parameters locally, creating the compressed file. No data ever leaves your device — it's the safest way to compress sensitive images.

Why Compress Images for the Web?

Images account for over 50% of an average webpage's total data. Large images slow down page loads, hurt your Core Web Vitals score (LCP in particular), and cost you organic ranking on Google. Compressing a 2 MB JPEG to 300 KB — without visible quality loss — can cut load times by seconds, reduce bounce rates, and have a measurable impact on ad revenue and conversions.

100% Client-Side — Your Data Stays Private

Cloud compressors often keep copies of your photos. ImageSetu is fundamentally different: the compression happens inside your browser. We never see your images, and they don't leave your device.

JPEG vs. WebP vs. PNG — Which Should You Choose?

JPEG: Best for photographs. Achieves the smallest file sizes with minimal visual loss at 70–85% quality. Universally supported. WebP: Google's modern format. Typically 25–35% smaller than JPEG at the same quality. Ideal for websites targeting Chrome and modern browsers. PNG: Lossless and supports transparency. Best for logos, icons, and graphics with sharp edges. Always larger than JPEG/WebP for photos.
