Reduce image file size while keeping quality
JPG, PNG, WEBP · Max 20MB
Image compression is the process of reducing the file size of an image while preserving as much visual quality as possible. It works by intelligently removing redundant data — colors and details that your eyes barely notice — to achieve dramatic file size reductions, often 60-90% smaller than the original. Compressed images load faster on websites, save bandwidth on mobile networks, fit more content in email attachments, and reduce cloud storage costs. Modern compression algorithms preserve visual quality so well that the difference is almost imperceptible at standard viewing distances.
Common use cases: optimizing images for faster website loading, preparing photos for email attachments, reducing storage on phones and cloud accounts, uploading galleries to social media without losing quality, sending photos via WhatsApp or messaging apps, and freeing up disk space on photo archives. SEO and Core Web Vitals also reward compressed images with better Google rankings.

Image compression reduces file size by removing redundant or imperceptible visual data. JPG uses lossy compression that intelligently discards detail your eyes can barely see, achieving 60-90% size reduction with minimal visible quality loss. The quality slider lets you balance file size and visual fidelity.
75% is the sweet spot for most use cases — strong compression with virtually invisible quality loss. Use 90% for professional photos, 60% for web galleries with many images, and 40-50% for previews or thumbnails. Never go below 30% unless you accept very visible artifacts.
No. Compression only reduces file size by improving how the data is stored. Image dimensions (width and height in pixels) remain exactly the same. To change image dimensions, use our Image Resizer tool instead.
FileTools supports JPG, PNG, WEBP, JFIF, and HEIC images. The compressor outputs JPG by default for maximum compatibility and best compression ratio. For PNG-specific optimization or transparency preservation, consider using Image Converter to switch formats.
Yes. Files are processed on our secure server and automatically deleted within 1 hour. We never store, share, or analyze your images. The compressor is also free and requires no signup.
