Free Image Compressor: Reduce File Size, Not Quality
Welcome to the #1 Free Online Image Compressor. In the digital world, speed is everything. Large image files slow down your website, fill up your phone’s storage, and are impossible to email.

Why Use Our Image Optimizer?
🚀 Boost Website Speed (SEO)
Google punishes slow websites. If you run a blog, e-commerce store, or portfolio, uploading raw images (3MB+) hurts your ranking. Use our tool to shrink them to 200KB. Faster sites rank higher and keep visitors happy.
🔒 Private & Secure (Client-Side)
Most compressors upload your photos to a cloud server to process them. We do not. Our tool uses your device’s own processing power to compress images locally. Your personal photos, ID cards, or client work never leave your computer.
📧 Email & Storage Friendly
Most email providers (Gmail, Outlook) have a 25MB attachment limit. If you try to send 10 high-res photos, it will fail. By compressing them first, you can send dozens of photos in a single email without hitting the limit.
Understanding Image Formats
Compressing JPG (JPEG)
JPG is a “lossy” format. Our tool intelligently removes data that the human eye cannot see, drastically reducing file size while keeping the photo looking sharp. Perfect for photography.
Compressing PNG
PNG is “lossless” and supports transparency. Our tool optimizes the color palette and metadata to reduce the size without destroying the transparency or sharp edges. Perfect for logos and screenshots.
Compressing WebP
WebP is the modern standard for the web. It offers the best compression. Our tool fully supports WebP optimization for next-gen website performance.
Frequently Asked Questions (FAQ)
Will my image look blurry?
No. At our recommended setting (0.7), the visual difference is almost imperceptible to the human eye, but the file size drops significantly. If you need higher quality, simply slide the “Quality” slider up to 0.9.
Can I compress multiple files at once?
Yes! You can select 10, 20, or even 50 images at once. Our tool processes them in a batch queue, allowing you to download them individually as they finish.
Does this work on Mobile?
Yes. This tool is fully responsive on iOS (iPhone) and Android. It is perfect for shrinking photos taken with your phone camera before uploading them to social media or forms.
