How to Make a Branded Upload Portal for Box

When a client needs to send you files, the upload page they see is a touchpoint in your customer experience. If that page shows Box's logo and branding, your brand disappears at a moment that should feel seamless.

A branded upload portal solves that. It's a custom upload page that carries your logo, your colors, your fonts, and your voice, while still sending files into your existing Box account. The uploader has no idea there's a third-party tool involved. They just see your brand, upload their files, and get a branded confirmation.

This guide walks through how to build one using EZ File Drop, a purpose-built tool that connects your Box to a fully brandable upload experience with no coding, no hosting, and no design team required.

Why Box File Request Isn't Enough for Client Work

Box File Request has come a long way. It supports custom form fields, handles large files on Enterprise tiers, and gives you a drag-and-drop form builder directly inside Box. For internal, Box-native workflows, it's a capable option.

For client-facing work, it still has real gaps:

• Business plan or higher required. You can't create a Box File Request on a personal or Starter plan. The feature is gated to Box Business, Business Plus, Enterprise, and Enterprise Advanced. If you're on a lower tier, File Request isn't available at all.
• Box branding, not yours. Upload pages show Box's logo and styling. There's no way to add your logo, change the colors, or customize the page copy beyond basic form labels. After an uploader submits, they see a Box-branded success screen.
• No embed option. Box File Request gives you a shareable link, but there's no embed code. Clients always leave your site to upload.
• Notifications only go to the Box account owner. There's no way to notify the uploader, your team, or a third party about new submissions.
• No dynamic file organization. Files all land in the folder you created the File Request on, no automatic subfolders or file renaming.

For client-facing file collection, a branded upload portal closes these gaps while keeping the files exactly where you want them: in your Box account.

What a Branded Upload Portal Gives You

EZ File Drop's branded upload portals for Box include:

• Your logo on the upload page, in email notifications, and on the success screen
• Custom colors, fonts, and page layout to match your website
• Custom page copy (headline, welcome message, drop zone text, success message) so the portal speaks in your voice
• Custom form fields for collecting context alongside the files (client name, project ID, email, categories, etc.)
• Automatic file organization in Box using form field data
• White-labeling on Business and Premium plans (no EZ File Drop branding anywhere)
• Embeddable on any website (WordPress, Webflow, Squarespace, Wix, or any page that supports HTML embeds)
• Works with any Box plan, including Starter and personal tiers where Box File Request isn't available

Files still land directly in your Box account, in the folders you choose, using your existing Box storage. EZ File Drop is the branded front door. Box is still the storage.

Step 1: Connect EZ File Drop to Box

Sign up at ezfiledrop.com/join. Every new account starts on a 7-day Business plan trial with 1 GB of upload bandwidth, no credit card required.

From the main dashboard, open Cloud Settings and click Connect to Box. EZ File Drop uses OAuth2 to link to your Box account, so your Box password never leaves Box. Approve the connection in the Box authorization window and you'll be returned to EZ File Drop with Box connected.

Unlike Box File Request, EZ File Drop works with any Box plan. For a detailed walkthrough of the connection step, see the Box connection tutorial.

Step 2: Upload Your Logo and Brand Assets

From the main menu, click Upload Forms, then Create New Form. In the form editor, give your portal a name and upload your logo.

A few things worth knowing about the logo:

• It appears at the top of the standalone upload portal page
• It appears in email notifications (upload confirmation, team notification, third-party notification)
• It appears on the upload success screen after a file is submitted
• If you plan to embed the portal on your website without a logo above the form, the logo is still used in emails, so upload one even if you plan to hide it in the embed

Then add a page header and welcome message. This is your voice. Write copy that matches your brand, formal for legal or financial workflows, warm and conversational for creative work, whatever fits the relationship you have with the people sending you files.

Step 3: Customize Colors, Fonts, and Layout

Open the Style editor to make the portal match your brand. The Form Element dropdown lets you toggle between every part of the portal and edit its styling individually:

• Page Background
• Page Header
• Page Text
• Form
• Inputs Labels
• Inputs
• Files Drop Zone
• Files List
• Submit Button

You can match your website's typography, color palette, spacing, and visual tone. On Business and Premium plans, the portal is fully white-labeled with no "Powered by EZ File Drop" footer and no EZ File Drop branding anywhere on the page or in the emails.

Step 4: Add Custom Form Fields

Form fields let your portal collect context alongside the files. EZ File Drop supports text fields, dropdown menus, checkboxes, and radio buttons. Any field can be marked required or optional.

Common fields for a branded upload portal include:

• Client or uploader name (used to organize incoming files)
• Email address (used to send upload confirmations)
• Project name or ID (used to route files into the right subfolder)
• Category or file type (dropdown for submission type)
• Notes or message (long-text field for context)

Field values can also be used to automatically organize incoming files in Box. More on that in the next step.

The file upload field itself is also configurable. You can require it, set a maximum number of files per submission, restrict which file types are accepted, and set a per-file size limit up to 150 GB on any plan.

Step 5: Point the Portal at Box and Set Up File Organization

In the Cloud Destination section, select the Box folder where uploaded files should land. Then use the dynamic file organization settings to automatically create subfolders and prepend file names based on form field data.

For example, a portal that collects a project name and an uploader name could route each file into a subfolder named after the project, with filenames prepended by the uploader. So a photo from Sarah Johnson for the Website Redesign project arrives in your Box as "Sarah Johnson - headshot.jpg" inside a "Website Redesign" folder. No manual sorting, no lost files.

For the full walkthrough, see the Dynamic File Organization tutorial.

Step 6: Publish and Share the Portal

Click Save and Publish. Your branded upload portal is live immediately.

Share as a Standalone Page

Every portal has a unique URL at ezfiledrop.com/yourteam/portal-name. The URL slug is editable. Share the link directly over email, in a proposal, or in a contract. No hosting, no configuration.

Embed on Your Website

Copy the embed code and paste it into your site. The embedded portal carries all your branding and fits seamlessly into your page design. Toggles let you show or hide the logo, header, and page text so the embedded version matches its surrounding page. Works on WordPress, Webflow, Squarespace, Wix, or any HTML-supporting site.

See the embedding tutorial for platform-specific setup.
