Choose filesWhy compress images?
Heavy images are one of the most common reasons a website feels slow. They hurt Largest Contentful Paint, one of Google’s Core Web Vitals, and they slow down email, uploads and storage too. This image compressor shrinks JPG, PNG, WebP and AVIF files, often by 60 to 90 percent, and shows you the result before you download.
Upload a PNG and you get a smaller PNG back. Upload a JPG and you get a smaller JPG. You only convert if you choose to. On the Download step, the arrow next to each image shows what it would weigh as JPEG, PNG, WebP or AVIF, so you can pick the smallest format that still works for you. If your original is already well optimized, it is kept as it is.
What next? Need to hit an exact size? Try the 100 KB compressor. Need another format? Use the image converter. Need different dimensions? Use the image resizer.

Frequently asked questions
+Is this image compressor free?
Yes. It is free with no watermark, no sign-up and no daily limit.
+Are my images uploaded to a server?
No. Compression runs in your browser, so your images stay on your device. Only the tool’s own code files are downloaded.
+Why do PNG files get bigger in some compressors?
Basic tools re-save the PNG without optimizing it. This tool reduces colors and repacks the file with a PNG optimizer, and it keeps your original if it can’t make it smaller. Choose “Lossless” if you want pixel-perfect output.
+How much smaller will my images get?
It depends on the image, but photos commonly shrink by 60 to 90 percent. Images that are already well optimized change little. The preview and the size shown next to each image tell you exactly what you will get.
+Which format is best for a website?
WebP and AVIF usually give the smallest files in current browsers, JPEG and PNG are the safest for compatibility. Open the format menu on the Download step to compare the real sizes of your own image.
+Can I compress an image to an exact size like 100 KB?
Yes. Set a maximum file size in the settings, or use the dedicated page for compressing an image to 50 KB, 100 KB or 200 KB.
