Compress Image for Online Form
Online forms for government services, university admissions, job applications, and exam registrations almost always specify a maximum photo file size — typically 50KB to 200KB in JPEG format. Uploading a full-resolution phone photo (3–8MB) will fail the size check. This guide shows how to compress your photo to meet any form's file size requirement in seconds.

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