Online Image Compressor – Shrink JPG, PNG & WebP

What is an Image Compressor?

An image compressor reduces the file size of photos and graphics while preserving as much visual quality as possible. metatool.in's free online image compressor works entirely in your browser using the HTML5 Canvas API — meaning your images are never uploaded to any server. No privacy risks, no file size limits, no subscriptions.

Smaller images load faster on websites, consume less storage, and are cheaper to serve via CDN. For web developers and content creators, compressing images before publishing is one of the highest-impact performance optimizations available.

How to Compress an Image

Click the upload area or drag and drop your JPEG, PNG, or WebP file directly onto it. metatool.in instantly shows a side-by-side comparison of the original and compressed image. Use the Compression Quality slider to fine-tune the balance between file size and visual fidelity in real time. When you're satisfied, click Download JPEG to save the result.
