Resize and Compress Images Without Uploading

The Resize & Compress Image tool on BonChecker allows you to resize and reduce the file size of your images instantly, all within your browser. There's no need to upload files, install apps, or worry about where your images are going. Everything runs locally, which means your files stay on your device.

Whether you're preparing images for a website, shrinking AI-generated artwork, or adjusting photos for social media, this tool gives you quick control over both dimensions and quality. Just drop in a JPG, PNG, or WebP file, set the width and height you want, and choose the compression level. You'll see a live preview of the result before downloading.

One feature that sets this tool apart is the option to lock the aspect ratio. When this is enabled, the image resizes proportionally, helping you maintain the original layout. You can turn it off if you prefer custom stretching or cropping. The quality slider, which ranges from 0.1 to 1.0, helps you adjust the balance between image clarity and file size—this is especially handy for email attachments, blog uploads, or online platforms with size limits.

Because it all works inside your browser, the process is fast, secure, and completely anonymous. Nothing is sent to a server. You don’t need an account, and there’s no watermark or ad clutter. It’s also designed to preserve or clean up EXIF data as needed, giving you better control over metadata visibility.

From resizing artwork and screenshots to compressing camera photos and AI images, this free tool makes the process simple and efficient—no matter what kind of user you are.
