The file never leaves your computer. No signup, no upload, no tracking.<\/p>\n<p>Use the quality slider to control the tradeoff between file size and visual quality. At 80% (the default), most photos look identical to the original. Below 60%, compression artifacts become visible around sharp edges and text. For photos, 70 to 85% is usually the sweet spot.<\/p>\n<h2>How JPG compression works<\/h2>\n<p>JPEG compression divides the image into 8&#215;8 pixel blocks and discards visual detail that the human eye is unlikely to notice. Lower quality settings discard more aggressively, producing smaller files with more visible artifacts. The quality slider above gives you direct control over this tradeoff. Since this tool re-encodes the image, there is a small generation loss even at 100% quality. If the original JPG is already heavily compressed, re-encoding at a higher quality setting will produce a larger file, not a better one.<\/p>\n<h2>Tips for the best results<\/h2>\n<p>Start at 80% and compare the output visually. If it looks good, try 70%. Photos with smooth gradients (sky, skin) tolerate lower quality than images with sharp text or line art. If you need a specific file size target (for example, under 1 MB for an email attachment), adjust the slider until the output size shown below the download button meets your goal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Need a smaller JPG for an email attachment or a website with upload limits?
