Reduce JPG, PNG, and WebP file sizes by adjusting quality and output format. Free, private, and lightning fast.
Select a JPG, PNG, or WebP image up to 20 MB. The original file size is shown immediately.
Choose your output format (JPEG, WebP, or PNG) and drag the quality slider. Lower quality means smaller files.
See the original size vs. the compressed size and the % reduction. Download your optimized image.
JPG/JPEG, PNG, and WebP images up to 20 MB are supported as input. You can also choose a different output format — for example, converting a PNG to JPEG for a much smaller file.
PNG is a lossless format, so the quality slider has no effect when PNG is selected as the output. The image is re-encoded as-is. For the best size reduction, switch to JPEG or WebP.
This can happen if the original was already well-optimized or if you switch to a lossless format like PNG. Try lowering the quality slider or switching to JPEG for maximum reduction.
