What is Image Compressor?
Large images are the single biggest cause of slow-loading web pages. Compressing your images before publishing can reduce file sizes by 50–90% with little to no visible quality loss — dramatically improving page speed and Core Web Vitals.
This tool compresses images entirely in your browser using the Canvas API. Your files are never sent to any server — they stay on your device throughout the entire process. No account, no watermarks, no limits.
You can process up to 10 images at once. Adjust the global quality slider and see the estimated compression ratio before downloading. Export individual files or batch-download all as a ZIP.
How to use
Frequently asked questions
No — all compression happens in your browser using the Canvas API. Your images never leave your device.
For photos on the web, 75–85% JPG or WebP quality is typically indistinguishable from the original to the human eye while cutting file size by 60–80%.
Yes. PNG is lossless by nature, but you can convert PNGs to JPG or WebP to dramatically reduce their file size (note: this loses transparency).
This can happen if the original was already highly compressed, or for very small files where canvas encoding overhead outweighs the compression gain. Try WebP output in that case.
