Compress JPG, PNG, WebP and AVIF images in your browser. Resize photos, batch convert formats, download ZIP files, and keep images private with no uploads.
This tool supports JPG, JPEG, PNG, WebP and AVIF output, plus common browser-decodable image inputs. Unknown supported inputs are converted through the browser canvas pipeline.
No, all image processing and compression happen directly in your web browser. Your images are not uploaded to any external server, ensuring your privacy and data security.
Lossy compression significantly reduces file size by removing some data from the image, which may result in a slight loss of quality. Lossless compression reduces file size without any loss of quality, but the compression ratio is lower.
Yes. You can output compressed images as JPEG, PNG, WebP or AVIF, regardless of the original browser-supported input format.
Absolutely. You can resize your images to one of our preset dimensions or specify your own custom width and height.
Yes, you can upload multiple images and compress them all at once. You can then download them individually or as a single zip file.
There's no single "best" setting; it depends on your needs. For web use, a quality between 0.7 (70%) and 0.85 (85%) often provides a good balance between file size reduction and visual quality. Experiment with the slider to find what works best for your specific image.
