How image compression works
This tool re-encodes your images using your browser's built-in Canvas API. By adjusting the JPEG quality parameter, it removes redundant data while preserving visual quality. At 75% quality, most images lose 40-70% of their file size with no visible difference to the human eye.
Unlike server-based compressors, your images never leave your device. The compression happens entirely in JavaScript — no upload, no waiting, no privacy concerns.
When to compress images
Website performance. Large images are the number one cause of slow page loads. Compressing before upload can cut load times dramatically.
Email attachments. Most email providers limit attachment sizes to 25MB. Compressing images lets you send more files in fewer emails.
Storage and backup. Compress photos before archiving to save disk space without losing the images you care about.
