Output: Exact Size JPG

💡 How it works: If the original image is larger than the target, we scale and adjust the JPEG quality intelligently to bring it close. If it is smaller (or once we get it close), we append safe, standard JPEG metadata comments (COM markers) to match the exact byte size without altering the visual quality of your photo. Output is always downloaded as a highly compatible .jpg format.

Frequently Asked Questions

What is the Exact KB Image Converter?

It is a target-driven image compressor that compresses and pads images (JPG, PNG, WEBP) to match an exact file size in kilobytes (such as 15KB, 20KB, 50KB) specified by the user.

How does the exact sizing work?

If the image is larger than the target, the tool adjusts resolution and quality. If it is smaller, it appends safe, non-destructive metadata comments (COM markers for JPG, private chunks for PNG, and PAD chunks for WEBP) to make the file size match the target exactly. The visual quality remains unchanged.

Which formats are supported?

The tool fully supports JPG, PNG, and WEBP formats. You can upload any standard image format and output it in the exact file format and size you select.

Why do government and exam portals require exact KB sizes?
