About This Tool
This free online image compressor reduces the file size of JPEG, PNG, and WebP images directly in your browser. Your images are never uploaded to any server — all compression happens locally using the Canvas API, keeping your data private and secure.
Quality Control: Choose from High (90%), Medium (70%), or Low (50%) quality presets, or set a custom quality level from 1 to 100. Higher quality means larger files; lower quality means more compression and smaller files.
Before/After Preview: Compare the original and compressed images side by side to visually verify that quality is preserved. Check the exact file size difference and the percentage saved.
Supports Multiple Formats: Works with JPEG (.jpg), PNG (.png), and WebP (.webp) images up to 100MB. The output format matches the input format by default, so your compressed image stays compatible with your workflow.
Use Cases: Optimize website images for faster page loads and better SEO. Reduce email attachment sizes to stay under limits. Free up storage space on your device by compressing photos. Prepare images for social media where file size limits apply.
