Introducing Image Resizer — Resize and Convert Images Without Uploading Them

We're excited to launch Image Resizer, the latest extension in the UnifyBrowse suite.

The Problem

You have an image. You need it at 1080×1080 for Instagram, or under 1 MB for an email, or in WebP for a web project. So you open some online tool, upload your file to a random server, wait, download the result, and hope nobody stored your image somewhere.

Every time. For every image.

The Solution

Image Resizer runs entirely in your browser. No uploads. No waiting. No servers. Just drag, set your dimensions, and download.

✨ Key Features

• Exact resize — Set any width and height. Image fills the canvas exactly.
• Fit mode — Scale to fit inside your target dimensions with a clean white letterbox. No distortion.
• Crop mode — Center-crop to fill exact dimensions. Perfect for square social posts.
• Format conversion — Export as JPG, PNG, or WebP with adjustable quality.
• Social media presets — One click to set Instagram, Twitter, LinkedIn and more standard sizes.
• Bulk mode — Drop a folder of images, set your settings once, and download everything as a ZIP.
• Live preview — See the result before you download, with file size shown.
• Works in a tab — On Linux and some systems, the popup opens in a full browser tab automatically so the file picker never closes it.

🔒 Privacy First

Image Resizer uses the browser's native OffscreenCanvas API. Your images never leave your machine. No account needed. No tracking. Nothing uploaded.

🚀 Get Started

1. Install Image Resizer from the Chrome Web Store
2. Click the extension icon and drop in an image (or click to browse)
3. Pick a preset or set custom dimensions
4. Choose Stretch, Fit, or Crop mode
5. Download

That's it. Five seconds from image to resized file.
