About this Image Compressor
Compress images for faster websites, email attachments and upload limits - without uploading your photos to a stranger's server. This image compressor re-encodes locally in your browser, shows exactly how many KB you saved, and lets you balance quality against file size with one slider.
How it works
Re-encodes the image through a canvas at your chosen quality. PNG is lossless in browsers, so quality mainly affects JPG/WebP output.
Privacy note: this tool runs locally in your browser. Your input is not uploaded, stored in analytics, or placed in the page URL.
