Step-by-Step Guide
5 steps · takes under 1 minute
Choose your background image
Pick any JPG or PNG — a landscape photo, a branded office background, a blurred room, or an abstract design. Avoid very busy patterns that distract during calls.
Crop to 16:9 ratio first
If your image isn't already 16:9, crop it to 16:9 using the Crop tool (set to 16:9 aspect ratio). Centre the interesting part of the image in the frame.
Resize to 1920×1080px
Set width to 1920 and height to 1080. Enable aspect ratio lock — if the image is already 16:9, both dimensions will calculate correctly with the lock on.
Save as JPG or PNG under 5MB
Zoom accepts JPG and PNG up to 5MB. A 1920×1080 JPEG at 85% quality is typically 200–600KB — well within the limit.
Upload to Zoom
In Zoom: Settings → Background & Filters → Virtual Backgrounds → click + to add your image. It appears immediately.
What to Expect
Subject isolated, background replaced with transparency
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.
