Common questions
Are my files uploaded to your server?
No — and we structurally can't be. Every tool on HandyCompress runs entirely inside your browser using WebAssembly. The file is read into your browser's memory, processed by your own CPU, and the result is downloaded — without ever leaving your device. You can verify this by opening your browser's Network tab and watching for zero data leaving while you work, or by disconnecting your WiFi after the page loads.
Is this really free? What's the catch?
Really free, no catch. Because the processing happens on your computer instead of our servers, our cost per file is zero. We pay for static hosting (a fixed cost regardless of usage), so there's no economic reason to gate anything behind a paywall. The site is supported by ads placed below the tool, never inside the workflow.
What's the maximum file size?
There's no artificial cap. The only real limit is your own device's RAM — a modern laptop can handle PDFs up to a few hundred MB and folders of hundreds of images without trouble. Phones have less memory, so very large files may be slow on mobile.
Does it work offline?
Yes, after the first visit. HandyCompress is a Progressive Web App — the tools cache locally and run even with the network disconnected. You can install it to your home screen and use it like a native app.
Why use this instead of iLovePDF or Smallpdf?
Those services upload your files to their servers to process them. For sensitive documents — contracts, tax forms, medical records, personal photos — that's a meaningful privacy concession. HandyCompress processes everything on your device, so the file never leaves. We also have no file-count or daily-use caps because we have no per-file cost.
