📤 Advanced File Upload Validator — Control What Gets Uploaded Before Bubble Touches It

Bubble’s FileUploader accepts almost anything, but real apps need rules, consistency, and control.
Advanced File Upload Validator gives Bubble developers a powerful client-side gatekeeper that validates, normalizes, and optimizes uploaded files before they are saved, trusted, or processed.

This plugin inspects image uploads in real time, extracts metadata, enforces size and dimension rules, validates aspect ratios, detects screenshots (from its naming, not all screenshots), normalizes filenames, strips EXIF data, resizes and compresses images, and outputs a clean, optimized file ready for storage. If a file doesn’t meet your rules, it’s blocked with a clear reason — no silent failures, no guessing.

It protects developers from inconsistent uploads, oversized files, broken layouts, bad filenames, bloated storage costs, and unpredictable user input. Instead of fixing files after upload (or worse, discovering issues in production), you enforce quality and consistency at the edge — where it’s fastest and safest.

This plugin is not about security scanning — it’s about control, performance, and reliability. Every file that passes is guaranteed to meet your standards, every time.

If your app handles user images, this plugin becomes part of your foundation.
