Compressing a certificate or ID scan to 200KB
Many portals ask for certificates, ID cards and other proofs as images under a few hundred kilobytes. At 200 KB a full page photographed with a phone can stay readable, including stamps and signatures, if you prepare it well.
Crop the photo to the edges of the document so no table or background shows. Resize it to around 1600 pixels on the long side. Then upload it here with the 200 KB target and JPG output, and zoom into the smallest text in the preview before you download.
Using 200KB as a web image budget
For a website, 200 KB is a reasonable ceiling for a large feature or header image. A photo of about 1600 by 1067 pixels usually fits at a good quality. Switching the output to WebP can make the same image noticeably smaller, or keep more detail at 200 KB.
Serve images close to the size they are displayed. A 4000-pixel photo scaled down by the browser wastes data, no matter how well it is compressed.
How the 200KB target works
The tool encodes the image at the highest quality and checks the size. If it is too big, it searches for the highest quality that fits. Only when the lowest quality is still over 200 KB does it scale the image down, in small steps, and report that it did.
Getting a smaller or larger result
Because the search starts at a high quality and works down, the result usually sits just under 200 KB rather than far below it. If you want an even smaller file, pick 100 KB from the target chips, or switch to By quality and choose a level yourself. PNG uploads default to JPG here, so the target applies without changing anything. Only PNG output, chosen by hand, ignores the target.
