File Uploads in Online Form Builders

Online form builders help businesses collect vital information to boost sales and improve customer service. They also come with easy-to-use features, allowing enterprises to build forms suited for their campaign without paying a developer.

One of the most helpful features of online forms is their support for file uploads. With this, businesses can collect valuable files or documents from their target audience through the internet. It also allows the collection of files of any type, such as PDF, jpg, png, recorded videos, and more, from users.

Simply put, it allows customers to send a file and the businesses to receive it for a seamless transaction.

It is groundbreaking as it no longer requires people submitting forms to send confidential files physically. Moreover, it enables businesses to save costs and spend their resources on their core services and products.

How to Use File Uploads?

To assist you, here’s a quick step-by-step guide that will help add file uploads to your form.

Add a field to your form

Integrating a file upload field into your online form is easy. You have to click on the File Upload button or drag and drop it to your desired location in the preview area.

File Uploads

Select supported files types

To ensure security in your form, only allow uploads of safe file types, whether images, documents, audio, or video. Here are the ideal file types to allow:

  • Pictures: .png, .gif, .jpg
  • Documents: .doc, .xls, .ppt, .pdf
  • Audio: .wav, .mp3, .mp4
  • Video: .mpg, .mov, .vmv

To add allowed files, ensure that you check out all of them.

Restricted file types

Meanwhile, you can also select which file extensions are restricted from uploading to your form.

To do this, you have to click on the File Upload panel and specify the extensions you’d like to allow in the Allowed File Extensions field. It will prevent files with other extensions from submitting to your online form.

Set the maximum size for file upload

It is also essential to set the maximum file size for your forms. However, by default, the total file size for attachments is established by your server. You can use this as your guide in setting your preferred maximum file size, allowing only up to the extent that your server can handle.

Include file upload links in the notification

To avoid logging in to your website dashboard now and then, you can add the files attached in the form through the email notification. An automated email notification is sent to you every time someone fills up your record.

FAQS on File Uploads

Read on the following frequently asked questions regarding the file upload field:

Why does the file upload process hang and never finish even if I’m not uploading a large file?

There could be misconfigurations in your SSL connection. You can touch bases with your site host and tap them to fix the error to address this. At some point, you can also troubleshoot SSL issues.

Why do uploaded files appear as links instead of attachments in email notifications?

It depends on the maximum attachment size of your email provider and the file uploaded to your form. For instance, if your email provider only allows up to 10MB attachment size, but a user uploads a file larger than 10MB, then it won’t be delivered.
