Reduce image file size — JPEG, WebP, or lossless PNG
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
Clacify's Image Compressor reduces the file size of JPEG, PNG, and WebP images using lossy and lossless compression — all processed locally in your browser with no server upload. Set your quality level to balance file size vs. image clarity. Ideal for compressing photos before uploading to Instagram, sharing on WhatsApp (which recompresses and degrades images), embedding in websites for faster page load, or attaching to emails with size limits. The compressed image downloads directly to your device with no watermark.
Upload your image to Clacify's Image Compressor and set the quality slider to 80–85% for JPEG. This typically reduces file size by 40–60% with no visible quality loss to the human eye. For PNG files, lossless compression is used — file size reduction is smaller but there is absolutely zero quality loss.
WhatsApp automatically compresses images you send, but you can control quality better by compressing first. Aim for a JPEG file under 500 KB at 80% quality. Use Clacify's Image Compressor to reduce your photo before sending to preserve as much quality as possible through WhatsApp's re-compression.
