Frequently asked questions
Common questions about the Image Compressor.
How much can I shrink a file without it looking worse?
It depends on the image, but for JPG and WebP you can often cut file size dramatically at a quality setting where the loss is hard to see. Lowering the quality slider or the max width reduces size further.
Which formats can I compress?
You can compress JPG, PNG and WebP images, and you can choose the output format as part of the process.
What does the max width setting do?
It resizes the image down to a maximum pixel width before compressing, which is often the biggest single saving if your photo is far larger than where it will be displayed.
Is the compression lossy or lossless?
JPG and WebP use lossy compression, so you trade a little quality for much smaller files; converting to those formats from PNG is where the largest savings usually come from.
Are my images uploaded to compress them?
No. Compression runs in your browser, so the images stay on your device the whole time.
