This guide shows how to quickly compress images for WhatsApp in your browser.

100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.

Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
