You may upload your scanned surveys in any file format listed below:

• JPEG (.jpg/.jpeg)
• PNG (.png)
• GIF (.gif)
• TIFF (.tiff/.tif)
• PDF (.pdf)

Which is the best?

Ideally, you should scan your paper forms with DPI 300 in black-white/grayscale settings and choose PDF as an output format.

The PDF file format is recommended as you can combine multiple pages in a single file and do not need to worry about large file sizes.

You could also use the TIFF file format which also allows multiple pages, but we have noticed that it often results in larger files that can take longer to upload.

This is how the optimal print setting may look like (Image Capture for macOS):
