Image to 20 KB and the size on the form
Some Indian exam and government photo uploads stop at 20 KB. That is a very small file for a face.
The browser recompresses a JPG toward 20 KB. A plain head-and-shoulders photo can make it. A group photo or a busy background usually cannot without looking harsh.
If it is still too big
Crop to the portal pixel size first, then compress from the original. This page does not know which portal you are using, and the picture is not uploaded.
Pixel rules and kilobyte rules are different. Resize first when the portal asks for both.
When Image to 20 KB is the right page
Image to 20 KB sits on this site because Image and 20KB are not interchangeable, even when they look similar in a file list. Some Indian exam and government photo uploads stop at 20 KB. That is a very small file for a face. Resize, crop, rotate, compress, or change a photo when the next form has rules. A head-and-shoulders photo can meet it. A group photo or a busy background usually cannot without looking harsh.

What you give up by leaving Image
Image tools redraw the picture in your browser. They do not upload the file. These tools do not recover detail the camera never captured. Upscale and HD modes enlarge pixels. They are not AI reconstruction.
Keep the original photo.
What you gain, and do not gain, with 20KB
The download has to be 20KB, because that is the format the next step named. A head-and-shoulders photo can meet it. A group photo or a busy background usually cannot without looking harsh. The browser recompresses a JPG toward 20 KB on your device.
This page does not know which portal you are using. Read the form.
A test that matches the real file
Start from the question the other software asked. If it asked for 20KB, Image to 20 KB is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. Some Indian exam and government photo uploads stop at 20 KB. That is a very small file for a face. The browser recompresses a JPG toward 20 KB. A plain head-and-shoulders photo can make it. A group photo or a busy background usually cannot without looking harsh. The limit is the part people skip, and it is the part that decides whether the download is usable. Crop to the portal pixel size first, then compress from the original. This page does not know which portal you are using, and the picture is not uploaded. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. Check three things in the download: it opens, the Image material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original Image as well when you are allowed to. Image to 20 KB is a convenience copy. It is not a new master. Photos fail uploads for three separate reasons: the format name, the pixel size, and the kilobyte size. Image to 20 KB only does the Image to 20KB step. If the form also prints a pixel size or a 20 KB or 50 KB cap, do that step with the matching tool, starting from the original each time. A second lossy save will not recover detail.
Here is the decision for Image to 20 KB. You start with Image and you stop when a real program accepts 20KB. The original pixels are what you have to work with. The edit is local. Pixels and kilobytes are separate rules. Crop to the portal size first. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

Other jobs start from the homepage, where each tool is named for the conversion it actually does.
