Compress Image to 150KB

150 KB sits in a comfortable middle ground. It is the cap on a good number of application portals, certification sites and HR systems that want a passport-style photo or a scanned signature without filling their storage, and it is also a reasonable budget for a product shot on a marketplace listing or an image in a newsletter. Compared with the 100 KB limit that many stricter forms impose, the extra 50 KB mostly buys you cleaner edges around hair, text and fine lines, which is where aggressive compression shows first.

For a typical photo from a phone, reaching 150 KB rarely needs a change in dimensions: an image around 1000 to 1200 pixels on the long side usually fits at a quality setting that looks normal on a screen. The tool only reduces the pixel size when lowering quality alone cannot get under the number. Very large originals, such as a 12-megapixel shot or a high-resolution scan, will come back smaller in pixels as well as in bytes. If the original is already under 150 KB, nothing is changed and you keep the file as it is. The preset target can be edited if your form quotes a slightly different figure, such as 120 or 200 KB.
