Image Compressor

Upload your image (JPG, PNG, WebP, or GIF) using the file picker or by dragging it into the upload area. Adjust the quality slider to your preferred level — 80% quality typically gives a great balance between size and appearance. Click Compress and download your optimized image instantly.

Most JPG images can be reduced by 40–80% in file size with minimal visible quality loss. PNG images with lots of solid colors can compress even more. The exact reduction depends on image content, complexity, and the quality setting you choose.

The compressor supports JPG/JPEG, PNG, WebP, and GIF formats. You can compress a JPG and keep it as JPG, or compress a PNG and keep it as PNG. The output format matches the input format to preserve transparency and color accuracy.

At quality settings of 75–85%, most people cannot see any difference between the compressed and original images when viewed on screen. The compression is perceptual — it removes data that the human eye is least sensitive to. Only at very low quality settings (below 50%) does visible degradation appear.

Yes. You can upload up to 20 images simultaneously and compress them all at once. Each image is compressed individually with your chosen settings, and you can download them all as a ZIP archive or save them one by one.

No. All image compression happens locally in your browser using the HTML5 Canvas API. Your images are never sent to any server or third-party service. They remain on your device throughout the entire process, keeping your photos completely private.

Yes. The Image Compressor is fully mobile-responsive. Open the tool in your mobile browser, select images from your photo gallery, choose your compression quality, and download the optimized images — all without installing any app.

For web use, set quality to 75–80% and use JPG format for photos, PNG for graphics with transparency. Aim for image file sizes under 200KB for standard web images. WebP format provides the best compression for web use if your website supports it.

PNG uses lossless compression, so quality settings don't dramatically reduce file size the same way as JPG. For significant PNG compression, try converting to JPG (if transparency is not needed) or WebP format using our image converter tools.

Yes, 100% free. No watermarks are added to your compressed images, there are no file limits, no sign-up required, and no premium tier. You can compress as many images as you need, whenever you need.
