Would you send an invoice as an image or a PDF?

I’m building Create Instant Invoice for freelancers and tradespeople who need a quick invoice without an account. Two early testers especially liked saving the invoice as an image to send from their phones.

Would you use that, or do you prefer a PDF? You can try a sample invoice at https://createinstantinvoice.com/ — it’s free, with no signup or watermark.

I’d appreciate honest feedback on the mobile editor, the exported invoice and anything that feels confusing. I’m the maker, so useful criticism is welcome.
