Image Compressor

When to use this

You're about to upload a hero image to your site and it's 4.7 MB straight from the camera. Your email newsletter platform caps images at 1 MB. Shopify is warning you that your product photos are slowing down your store. These are compression moments — you need the same image, just smaller.

The other common trigger is platform-specific size limits. WordPress media uploads, Squarespace backgrounds, Etsy listings, LinkedIn posts — they all have ceilings. Rather than guessing, compress to 200–500 KB and you'll clear virtually every platform's requirements without visible quality loss.

One important rule: always resize first, compress second. Compressing a 4000×3000 photo and then displaying it at 800×600 wastes most of the work. Resize to the display dimensions, then compress. You'll get dramatically smaller files with better visual results.

Good to know

85% quality is the sweet spot. Below 85%, you start seeing artifacts — banding in gradients, fuzz around text. Above 90%, files barely shrink but you're burning bytes on imperceptible detail. For most web images, 80–85% is where quality and size meet.

Diminishing returns above 90%. Going from 90% to 100% quality roughly doubles file size while producing differences only a pixel-peeping comparison tool would catch. Save the 95–100% range for print-quality originals you'll never serve on the web.

WebP output beats JPG. If your platform supports it (and in 2026, nearly all do), choose WebP output. It produces files 25–35% smaller than JPEG at the same perceived quality. It's the single biggest free win in image optimization.

Compression is lossy and one-way. Once you compress, the discarded data is gone. Always keep your original files. Compress copies, not sources.

Everything stays on your device. No server upload, no account, no tracking. Your images never leave your browser tab.
