Why Client-Side Processing Changes Everything

Legacy file converter sites upload your personal files to distant cloud servers. File Fix Hub executes WebAssembly code inside your browser so your files never leave your computer or phone.

100% Private & Leak-Proof

Because your files are read directly into local browser RAM, no server ever sees, stores, or logs your confidential bank statements, tax returns, or personal photos.

Zero Network Lag

Uploading a 500MB PDF to a cloud server takes minutes. Running Canvas & WebAssembly locally processes files in milliseconds with zero network waiting time.

No File Size Limits

Other sites cap uploads at 15MB to save bandwidth unless you pay $12 per month. File Fix Hub leverages your device's native RAM, so there are no arbitrary paywalls.

Frequently Asked Questions

Got Questions? We Have Answers.

Everything you need to know about our privacy technology and browser-based tools.

How do you guarantee my files are 100% private and never uploaded?
Unlike traditional file conversion sites that send your files to remote servers over HTTP, File Fix Hub runs all parsing, image manipulation, and PDF compiling inside your browser using JavaScript, HTML5 Canvas, and compiled WebAssembly (WASM). Your files never leave your device RAM memory and are discarded as soon as you close or refresh the page.
Are there any file size limits or paywalls?
No! Because processing uses your own device hardware, we do not pay expensive cloud processing server bills per file. This means there are zero arbitrary file size limits, zero daily usage caps, and no paid subscription accounts.
Does File Fix Hub work on mobile phones (iOS & Android)?
Yes, File Fix Hub is built mobile-first. You can compress photos, convert JPG to PNG, or merge PDFs directly from your iPhone, iPad, or Android phone without installing any app from the App Store or Google Play.
What browsers are supported?
All modern web browsers supporting WebAssembly and HTML5 Canvas API are supported, including Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, and Brave across desktop and mobile devices.
Why does File Fix Hub display advertisements?
File Fix Hub is 100% free to use. Advertisements help cover domain hosting, software development, and open-source maintenance. All ad slots are strictly separated from tool action buttons so they never interfere with your file converting experience.
