How Panda would explain it

A simple way to decide between PDF, JPG, PNG, and Word when an upload form is not very clear. Short answer: if the form does not say much, PDF is usually the safest choice.

  1. 1

    Start by checking whether the destination expects a document or an image.

  2. 2

    Use PDF when layout stability matters, JPG for lightweight image previews, and Word only when the receiver must edit the file.

  3. 3

    If an image upload is rejected, switch to a PDF workflow before trying again.
