Reduce file size without a server upload
Compression happens with your browser's image encoder. Lower quality usually reduces size more, but can also remove more visual detail.
WebP or JPG?
WebP often provides an efficient balance for websites, while JPG remains a simple compatibility choice for photographs. Compare the downloaded result before replacing an original.
Keep originals
Compression is destructive. Keep the original file if you may need to edit or export it again later.
