What is Image Compressor?
Large images are the most common cause of slow web pages. DailyDevTools' Image Compressor reduces the file size of PNG, JPEG, and WebP images directly in your browser using advanced compression algorithms — no files are ever uploaded to a server. Reducing image sizes by 50–80% dramatically improves page load time, Google PageSpeed scores, and Core Web Vitals.
How to use Image Compressor
- 1Click Upload or drag and drop one or multiple images into the drop zone
- 2Use the quality slider (1–100) to control the compression level — 75–85 is the sweet spot for most images
- 3Compare the original and compressed file sizes shown for each image
- 4Click Download to save the compressed images, or Download All as a ZIP file
