Why online forms reject photos
Application portals check three things at once: the pixel size (for example 276 × 354), the file size in KB, and the file type. A phone photo is usually 3 to 6 MB and thousands of pixels wide, so it fails all three.
Fixing only one is not enough. Shrinking the pixels often brings the file under the limit, but some forms also have a minimum size and reject files that are too small. This tool hits the pixel size first, then tunes JPEG quality to land inside your KB range.
Limits differ between forms and change from year to year. Always read the official notice for the exact numbers and use the fields above to match them.
KB, pixels and DPI explained
- Pixels are the width and height of the picture. More pixels means more detail and a bigger file.
- KB is the size of the file on disk. At a fixed pixel size it depends mostly on JPEG quality and how busy the picture is.
- DPI only converts centimetres to pixels. A 3.5 × 4.5 cm photo at 200 DPI is about 276 × 354 pixels. The file itself does not change with DPI.
When a form asks for centimetres, pick cm or mm above and set the DPI the form mentions. If it does not mention one, 200 DPI is a common choice, but check the notice.
Tips for a good photo
- Use even light from the front, with a plain, light background and no shadows on your face.
- Look straight at the camera with your head and shoulders centred, then crop so the face fills most of the frame.
- Crop first, then let the tool pick quality. A tight crop keeps more detail at a small KB limit.
- If the result is over your limit, reduce the pixel size a little instead of lowering quality further.
Private by design
Your picture is decoded, cropped and re-encoded inside this page. Nothing is uploaded, and the site cannot make network requests. Because the result is drawn onto a canvas and saved fresh, it carries no EXIF data, so the camera model and GPS location from your original are gone.
Questions
Is my photo uploaded anywhere?
No. The image is processed in your browser and the page blocks network requests, so it never leaves your device.
Does it remove EXIF and GPS data?
Yes. The output is re-encoded from pixels, so camera details and location data from the original are not included.
How does it reach a KB range?
It sets the exact pixel size, then searches JPEG quality for the highest value that stays under your maximum. If the file ends up below your minimum, it adds invisible comment bytes to the JPEG so the size reaches it.
What if the file is still too big?
Lower the pixel dimensions, crop tighter, or raise the maximum if your form allows it. The tool shows the smallest size it could reach and suggests smaller dimensions.
Are the preset sizes official?
No. They are common examples. Every form sets its own pixel size and KB limits, so enter the values from your official notice.
