// quick guide
Image compression reduces the file size of images in bytes without degrading their visual quality below an acceptable threshold. Compressing images is vital for web performance, as smaller images load faster and consume less bandwidth.
How to use this tool:
- Drag and drop your images into the dropzone, or click to browse files.
- Select your output format: WebP (highly optimized next-gen format), AVIF (superior compression), JPEG, or PNG.
- Adjust the quality slider to find the perfect balance between file size reduction and image clarity.
- Preview the compressed size and quality side-by-side with the original image before downloading.
// frequently asked questions
What is the difference between WebP and AVIF?
WebP is widely supported by all modern browsers and offers excellent compression compared to JPEG/PNG. AVIF is a newer format that provides even better compression and quality retention than WebP, although it may have slightly longer compression times.
Does compressing images here upload them to a server?
No. The image compression engine runs locally in your browser using client-side JavaScript APIs. Your private images are never uploaded or stored anywhere.
Can I batch compress multiple images at once?
Yes. You can upload multiple files simultaneously. The tool will process them in parallel and let you download them all in a single batch, maintaining local browser-based execution.
