Reduce image file size online — supports JPG, JPEG, and PNG.
Lower quality = smaller file. PNG files are losslessly optimized (quality ignored).
Upload a JPG or PNG, choose the quality you want, and download a smaller image that is easier to share, upload, and publish.
Large image files slow down your website, inflate email attachments, and fill up storage space fast. Our free online image compressor solves all of that in seconds. Simply upload a JPG or PNG photo and our tool will intelligently reduce its file size while keeping your image looking sharp and professional.
For JPEG images, you can control the exact compression level using the quality slider. A setting of 70–80% is ideal for web use — it dramatically reduces file size without any noticeable loss in sharpness. At 50%, you still get a clean image perfect for email and social media. PNG files are automatically losslessly optimized, meaning every pixel is preserved while unnecessary metadata and color chunks are stripped away.
Unlike desktop software or heavy apps, there is nothing to install. The compression happens entirely online. Your file is processed securely on our servers and the result is returned directly to your browser for download. We do not store your images or share them with third parties.
Web developers compress images to hit Core Web Vitals targets and improve Google PageSpeed scores. Bloggers reduce photo size before publishing to WordPress or Webflow. E-commerce sellers shrink product photos for faster loading on Shopify, WooCommerce, and Amazon. Marketers compress banner images before sending email campaigns through Mailchimp or Klaviyo. Students and office workers shrink photos before attaching them to emails or reports.
Whether you are compressing a single headshot or batch-planning hundreds of product images, our tool gives you full control with zero complexity. Try it now — no sign-up, no limits, completely free.
