Make an image a bigger file to meet a minimum upload size. Choose a target such as 20 KB or a range like 20 KB to 50 KB, and the tool brings the file up to that size while the picture stays exactly the same. Everything happens in your browser and nothing is uploaded.

Increase Image Size in KB raises the file size of a photo to a number you choose, without changing how it looks. Some upload forms reject a file for being too small and ask for a minimum, such as 20 KB, or a range like 20 KB to 50 KB. This tool adds harmless extra data to the file so it reaches the size the form wants, while the picture stays the same.
Upload your image, type the size you need in KB or MB or pick a preset, and the tool builds a new file at that exact size. The photo looks identical because the extra weight comes from data added after the image, not from stretching the picture. When you are happy with the new size, press Download and upload the file to your form.
Many government, exam and job portals set both a smallest and a largest file size. If your photo or signature comes out under the minimum, the form will not accept it. This is common when a scan or a phone photo is already small. Use this tool when a site says the file must be at least a certain size, or must fall inside a range such as 20 KB to 50 KB.
No. The tool keeps your original image and adds extra bytes until the file reaches the target. Image viewers ignore those trailing bytes, so the photo opens and looks exactly as before, with the same width and height. If your image already starts larger than the target, the tool first reduces it to fit and then tops it up to the exact size you asked for.
All of the work happens in your browser using your own device. Your images are never uploaded to a server, there is no account or sign up, and no watermark is added. Close the tab and nothing is left behind, which makes this a safe way to prepare photos, signatures and documents for an upload.
