What is an Image Compressor?

An image compressor reduces the file size of an image by lowering its quality level or removing unnecessary metadata, while keeping the image visually acceptable. Smaller images load faster on websites, consume less bandwidth, and reduce storage costs. Image compression is one of the most impactful web performance optimisations available — images typically account for 50–90% of a webpage's total download size.

JPEG compression is "lossy" — it discards some visual data permanently to achieve smaller sizes. PNG compression can be lossless (no quality loss) or lossy. WebP is Google's modern format that achieves significantly smaller sizes than JPEG and PNG at equivalent quality. Our tool uses browser-side canvas rendering to compress images by adjusting quality level, letting you find the sweet spot between file size and visual fidelity.

How to Use the Image Compressor

1. Drop your image onto the upload zone or click Choose Image to browse.
2. Adjust the Quality slider (10–100%). Lower values = smaller file, lower quality.
3. Compare the Original and Compressed previews side by side with file sizes.
4. Натисніть Download Compressed Image to save the optimised file.
