Compress Images

Most online image compression tools require you to upload your photos to a remote server. That means your personal images travel across the internet, sit on someone else's infrastructure, and may be stored indefinitely without your knowledge. LocalForge takes a fundamentally different approach. When you compress an image here, the entire operation happens inside your browser using client-side JavaScript and Web Workers. Your files never leave your device.

This matters more than most people realize. Images contain EXIF metadata including GPS coordinates, camera serial numbers, timestamps, and sometimes even thumbnail previews of the original unedited photo. Uploading these to a third-party server exposes information you may not intend to share. With LocalForge, that metadata stays on your machine unless you choose otherwise.

Our compression engine supports JPEG, PNG, and WebP formats with adjustable quality settings. Web Workers handle the processing in a background thread so your browser remains responsive even when compressing large files or batches. The algorithms balance file size reduction against visual quality, typically achieving 60-80% size reduction with minimal perceptible loss.

Whether you need to compress images for email attachments, website optimization, or storage constraints, you can do it here without trusting a third party with your data. No account required, no upload limits, no waiting for server processing. Just drag, compress, and download.
