Reduce image file size instantly. 100% in your browser.
60Image compression is the process of reducing the file size of an image. Large images slow down websites, clog up email inboxes, and take up storage space. Compressing them makes them easier to share, upload, and store — often with little or no visible loss in quality.
There are two main types of compression: lossy and lossless. Lossy compression (used by JPG) permanently removes some data to achieve smaller file sizes. Lossless compression (used by PNG) reduces file size without removing any data. For most purposes, lossy compression at 60-80% quality looks nearly identical to the original.
Using the tool is simple:
Your image is never uploaded to a server. Everything happens on your device, so your files stay private.
When you compress a JPG, the algorithm analyzes the image and removes subtle color variations that the human eye is unlikely to notice. It also groups similar pixels together, reducing the amount of data needed to represent the image. The result is a file that looks almost identical but is much smaller.
PNG compression is different. It is lossless, meaning the image remains pixel-perfect. PNG is best for graphics, logos, and images with text, where sharp edges matter. For photographs, JPG is usually the better choice because it compresses much more efficiently.
Imagine you have a 4 MB photo from your phone that you want to upload to a website. Many platforms have a 2 MB limit, so the upload fails. You open our Image Compressor, set the quality to 70, and compress the image. The result is a 1.2 MB file that looks nearly identical on screen. The upload succeeds, and the page loads faster for visitors.
This is why image compression matters: it makes your images usable in the real world, without sacrificing visible quality.
No. All processing happens in your browser using the HTML5 Canvas API. Your image never leaves your device.
JPG, PNG, and WebP images are supported. The output is always JPG for best compression.
No. Compression reduces file size, but the dimensions (width and height) stay the same.
60-80 is a good range. Lower values mean smaller files but more quality loss. For photos, 70 is usually a safe choice.
Our current tool compresses one image at a time. You can repeat the process for multiple files.
Yes. The compressed image does not include EXIF metadata (like camera settings or GPS location). This is good for privacy.
