Image preparation help
Resize a photo or signature for an online form
Application portals can check image dimensions, format and file size independently. Start with the current instructions for the exact form you are submitting, then enter those limits in the image preparer.
Find the exact requirements first
Write down the required format, width and height, any minimum or maximum file size, and any crop or background rules. Requirements vary by organization and application cycle. A rule from an older notice or another exam may not match the form in front of you.
FormReady is an independent utility. It does not receive official portal rules or certify that a file will be accepted. Do not treat a preset or an example from another site as current instructions.
Match dimensions and crop ratio
If the portal gives pixel dimensions, use those values directly. If it gives a physical size and a dots-per-inch value, a basic conversion is:
pixels = millimetres ÷ 25.4 × DPI
For example, 25.4 mm at 300 DPI corresponds to 300 pixels. Use that calculation only when the instructions specify both physical size and DPI; a portal that checks pixels may not care about print metadata.
Set the crop to the same width-to-height ratio as the target image. Resizing a square crop into a tall portrait can stretch the image or cut off important areas. Inspect the final crop before saving.
Meet the file-size limit without guessing
Pixel dimensions and file size are separate checks. JPEG quality and image detail affect how many kilobytes a file uses, so the same dimensions can produce different file sizes. Reduce quality gradually, then check the measured output against the portal’s minimum and maximum rather than assuming that “smaller” is always better.
Use the requested format. Changing a filename extension does not convert an image. If the portal accepts only JPEG, make sure the downloaded file is actually JPEG.
Review the saved image
- Compare the downloaded dimensions, format and measured file size with the current official requirements.
- Open the result and check that the face or signature is clear and not stretched.
- Keep the original image so you can retry with a different crop or quality setting.
- Upload the result to the official portal and follow its own validation messages.
The image is processed in your browser and is not uploaded to FormReady. That protects the local workflow, but only the application portal can decide whether a submitted file meets its rules.
