What are the best practices for placing QR codes on marketing materials?

Place your QR code where it’s easy to see and scan, like the front of a flyer, the corner of a poster, or the back of a business card. Make sure there’s enough contrast between the code and the background, leave some white space around it, and include a clear call-to-action so people know what will happen when they scan.

How do I remove or undo a highlight in a PDF?: To undo a highlight with an online PDF editor, use Ctrl + Z or Cmd + Z. To remove a highlight with QuillBot’s free online PDF editor, click on the highlight you want to remove. When the highlight editor displays, click the trash icon.

How do speech-to-text tools work?: Though the specifics vary across different speech-to-text tools, they all follow the same general process:

The sound waves generated from a voice are recorded using a microphone and converted into digital signals a computer can understand.

These digital signals are processed to remove any unwanted noise and matched with phonemes (units of sound in language).

These phonemes are analyzed and combined, often using artificial intelligence, to build corresponding words and sentences.

These words and sentences are then stored as text.

If you’d like to see this process in action, try QuillBot’s free speech-to-text converter.
What is an online QR code?: An online QR code is another term for a “dynamic QR code.”

When you scan one, your phone first opens an intermediary link managed by a redirect service. That link then forwards you to the most up-to-date content or action defined by the QR code’s creator.

It’s called an online QR code because you need an internet connection for it to work. Some QR code content—such as Wi-Fi login details—needs to be available offline, so it must be stored in a “static QR code,” where all the information is directly contained in the code itself.

How long should a newsletter be?: The ideal length for a newsletter depends on your audience and goals, but in general:

Short and scannable wins. Most readers prefer 200–500 words, broken into quick sections with clear headings.

Value over volume. Instead of focusing on word count, focus on delivering one to three strong takeaways your subscribers can act on right away.

Mobile matters. Since many people read newsletters on their phones, concise copy, bullet points, and links to learn more often perform better than long essays.

If you have a lot to say, consider linking out to a blog post, video, or resource page rather than cramming everything into the email itself. That way, your newsletter stays engaging and easy to digest while still driving traffic to your deeper content.
