Frequently asked questions
Which formats compress best?⌄
JPG and WebP support lossy quality control. PNG is lossless, so it is re-encoded as JPG or WebP for meaningful savings.
Is there a file size limit?⌄
There's no hard server limit because nothing is uploaded, but very large images may be slow on low-memory devices.
