Image to PDF combines JPG, PNG or WebP photos into one file in your browser. Add up to 30 images (50 MB each), preview each page, remove extras, then download. Free, no login.
Open the finished PDF once and check the page order before you email or upload it. Keep the original photos until the portal accepts your submission.
Next: Compress PDF if the file is still too large, Merge PDF to join other documents, or Compress Image if a photo is too heavy before you convert. More PDF tools sit in the same category list.
