Short-lived upload authorization
WordPress creates a time-limited signed upload authorization instead of receiving the full file payload.
Direct cloud uploads for WordPress forms
Files skip the server. Your forms don’t.
EdgeUpload turns supported form file fields into browser-to-cloud upload fields. Visitors send files directly to your own object storage, while the final cloud URL travels with the familiar form submission.

A shorter data path
Move the file, not your form workflow.
EdgeUpload asks WordPress for a short-lived upload signature. The browser uses it to upload to your configured bucket, then submits the resulting file URL through your existing form plugin.
Browser to your cloud bucket
The file moves directly from the visitor’s browser to storage you configure and control.
A cloud URL joins the entry
Your form plugin continues handling layout, validation, notifications, and entries with the final file URL.
Works alongside your stack
Keep the form plugin your team already knows.
EdgeUpload focuses on the upload path. It does not replace your form builder.

Common questions
Before you connect a bucket.
Does EdgeUpload store uploaded files on my WordPress server?
No. Files upload from the visitor’s browser directly to your configured cloud storage bucket. The resulting cloud URL is passed with the form submission.
Which storage providers does EdgeUpload support?
EdgeUpload supports Amazon S3, Tencent Cloud COS, Alibaba Cloud OSS, Azure Blob Storage, and Google Cloud Storage.
Do I need to configure CORS?
Yes. Your bucket must allow browser uploads from your WordPress site origin. EdgeUpload includes a CORS test to help verify the configuration.
Does it replace my form plugin?
No. Your form plugin continues to handle the form layout, validation, notifications, and entries. EdgeUpload changes the file upload route.
Can I limit it to specific forms?
Yes. You can optionally target specific form IDs; otherwise it can handle supported file fields across compatible plugins.
Give large uploads a more direct route.
Install EdgeUpload from the official WordPress Plugin Directory and connect your cloud storage.
