Image Compressor
Compress JPEG, PNG, and WebP images instantly.
What is Image Compression?
Image compression reduces file size by removing unnecessary data while maintaining visual quality. This makes images load faster on websites, reduces bandwidth usage, and saves storage space. Our compressor works entirely in your browser using the Canvas API — your images never leave your device.
You can compress JPEG, PNG, and WebP images with adjustable quality settings. Optionally resize images to specific dimensions and convert between formats. Perfect for optimizing photos for web use, social media, or email attachments.
How It Works
Select your images, adjust the quality slider (lower = smaller file size, higher = better quality), optionally set a max width to resize images, and click Compress All. The tool processes each image using the Canvas API, maintaining aspect ratio and applying your chosen settings. Compare before/after results with the slider on each image.
Supported Formats
JPEG: Best for photos with many colors. Lossy compression with adjustable quality. PNG: Best for graphics, screenshots, images with transparency. Can be lossless or lossy. WebP: Modern format with better compression than JPEG/PNG. Supported by all modern browsers.
Privacy & Performance
All compression happens locally in your browser. Your images are never uploaded to any server. There are no file size limits or processing limits. Works offline once the page is loaded. For best performance, process images in batches of 10-20 at a time.
