Free file tools. No signup. No watermark. No uploads.

Why processing in the browser matters

Most free file tools work by uploading your document to a server, processing it there, and sending the result back. That is fine for a takeaway menu and a poor idea for a bank statement, a passport scan, a signed contract, or anything your employer would rather you kept in-house.

Filezy takes the other approach. Modern browsers are capable enough to merge PDFs, render pages to images, and re-encode photos without any server involvement at all. Your files are read from your disk into your browser's memory, processed there, and written straight back out as a download. There is no upload, so there is no copy sitting in someone's temporary storage, no retention window to trust, and nothing to be exposed if that storage is ever misconfigured.

You don't have to take our word for it. Open any tool, let the page finish loading, then turn off your internet connection and use it. It will work. Or press F12, open the Network tab, and watch: adding a file produces no upload request. That test works on any file tool, and it is the quickest way to tell the two kinds apart.

What Filezy can and can't do

Running locally has limits worth being upfront about. Operations that need heavy computation or large models — OCR to make a scan searchable, aggressive PDF compression, editing text inside a PDF — genuinely need a server, and we don't pretend otherwise. What browsers handle well is exactly what most people need most often: combining, separating, rotating and trimming PDFs, building PDFs from photos, and converting, resizing and compressing images. Those are the tools here.

The other real limit is memory. Because everything happens on your device, a very large job is bounded by your available RAM rather than by our policy. On a laptop that ceiling is high; on an older phone it is lower.
