Increase a photo's file size to an exact target in KB without changing how it looks or its dimensions. For forms that require a minimum image size — the opposite of a compressor.
Many exam and government upload forms require a photo to be at least a minimum size (e.g. "20KB to 50KB"). If your photo is too small, the form rejects it. This tool pads the file up to the size you need.
