A few useful details
Does “under 50KB” mean exactly 50KB?
No. The default is strictly below 50,000 bytes. A smaller file can meet an upper limit. If your form also specifies a minimum, enter it under Other upload requirements.
Will the picture stay the same size?
Not always. Without fixed dimensions, we may reduce the pixel dimensions to meet your file limit. Original and output dimensions are shown side by side. Enter a width and height if your form requires exact pixels.
Does passing the checks guarantee my upload will be accepted?
No. These checks cover only the size, pixel dimensions and JPEG format you entered. A website may also check photo content, background, capture method or other rules. This tool does not certify official requirements.
