What does Image to PDF do?
Image to PDF is a free online tool that can convert one or more images into a single PDF. The PDF result from Image to PDF is a separate copy to inspect before you use it elsewhere. One possible use is mixed-format scans gathered into one attachment.
Image to PDF combines pictures from several supported image formats into one PDF. It is useful when an attachment limit or file workflow calls for one file instead of many separate pictures.
Mixing width and height or orientations can lead to pages with different shapes, so check the final file rather than assuming a uniform sheet layout. The content remains image-based and can be recognized with OCR separately if you need searchable words.
A set of pictures can form one PDF for easier sharing. The picture files still determine how sharp the pages look.
Arrange the uploads in the desired sequence. Check whether mixed shapes produce a useful reading view. This step does not read text or restore a scan's missing edges.

Formats and limits for Image to PDF
The Image to PDF form accepts the image formats in the table sources. Each Image to PDF upload can be up to 300 MB, which equals 300 MiB. The allowed suffixes on the Image to PDF page do not prove that a source has valid content inside it.

The result is not an editable reconstruction of image content. Animated or multi-frame sources may be interpreted differently by the format change engine.
How this tool works
Image to PDF uses ImageMagick to handle the source on the server. The Image to PDF request uses your chosen input rather than any local editing project left on your device. Check the PDF contents produced by Image to PDF before treating them as ready for another app or reader.
For Image to PDF, your browser uploads the source to our file-processing server. This is a server task, not local editing.
Files are due for deletion within 1 hour. Cleanup runs during normal service operation. Keep a local download for future use.
