Quick answer

Choose the size that matches your limit (for example Compress Image to 50 KB). Each tool lowers JPG quality first and reduces pixel size only when needed, then shows the new size before you download.

Online application forms, exam portals and bank uploads often reject pictures that are too large, and sometimes too small. The tools below cover the usual limits: 5 KB to 500 KB for photos and signatures, 1 MB and 2 MB for documents, ranges such as 20 KB to 50 KB, and general tools where you type your own size. If a form needs a minimum size, the increase-size tools pad the file without changing the picture.

A file gets smaller in two ways: lower JPG quality, or fewer pixels. The tools use quality first and shrink pixels only when quality alone cannot reach the target, so you keep as much detail as possible.

General tools (choose your own size)

Very small: 30 KB or less

Form sizes: 31 KB to 150 KB

Larger: 200 KB to 2 MB

Between two sizes (KB range)
