File tools that never see your files.

Twenty-eight tools for video, audio, images, PDFs and text. Every one of them runs inside your own browser tab, on your own machine. Nothing is uploaded, because there is nowhere to upload it to.

Browse all 28 tools How it works

Drop a file to find the right tool

We read the type and show you what can be done with it. Video, audio, image, PDF or plain text.

Browse tools

Your file stays on your device. Nothing is uploaded.

There is no upload step

The file you pick is opened by your browser and handed straight to the tool. That is the entire journey — no transfer, no server hop, no waiting room.

No account, no queue

No sign-up wall, no email capture, no "your file is 14th in line". You open the page and the tool is ready.

Keep working offline

After a page has loaded once, you can disconnect and carry on. Nothing about the work you do needs a connection.

Five kinds of work, twenty-eight ways to do it

Each category is a set of small, single-purpose tools. Open one, do the thing, close the tab.

The six people open first.

Compress Image Shrink JPEG, PNG and WebP without sending the original anywhere. Generate Password Pick a length and a character set. Nothing to upload, because there is no input file. Format JSON Paste a blob, get it readable — and find the comma that broke it. Merge PDF Put contracts, invoices or scans into one document, in the order you choose. Trim Video Set the start and end, keep the middle, save the clip. HEIC to JPG Turn iPhone photos into something every other device can open.

How it works

01

Open the tool and choose your file

Or drag it onto the page. Some tools take text instead — those open with a box already waiting. Nothing happens until you say so.

02

Set what you need

A quality slider, an output format, a page range. The tool reads your file locally and shows you the result before you commit to saving anything.

03

Save it where you want it

Your browser writes the finished file to your downloads folder like any other download. Close the tab and the working copy is gone — we never had it.

What happens to your file

Nothing. That is the whole answer.

When you pick a file on Filezaar, your browser opens it from your disk and hands it to the tool running in the same tab. There is no request to a server in the middle, because there is no server-side step in the design. You can verify this yourself: open the network panel, drop a file, and watch how quiet it stays.

  • Read from your disk by your browser, not by us.
  • Held in the tab while the tool works, then discarded.
  • The finished file is saved by your browser to your device.
  • Closing the tab clears everything. There is no copy left behind anywhere.
  • No account, so nothing ties a file to a person.
  • Nothing is recorded about what you process or what is inside it.

Why not an upload site

Most online file tools are a form that posts your file to someone else's computer. This is what changes when that step disappears.

A typical upload site

Your file travels over the network to a server you cannot see.
You wait in a queue behind everyone else's jobs.
Size caps are set by a plan, not by your hardware.
A retention policy decides how long the copy lives.
Private documents pass through infrastructure you did not choose.
Big files need an account, and an account needs an email.

Filezaar

The file is opened on your device and stays there.
No queue. The only other job is yours.
The ceiling is your own machine, not a pricing tier.
Close the tab and the working copy stops existing.
Contracts, medical scans and unreleased footage never leave the room.
No account exists to create, so none is asked for.

Questions people actually ask

Are my files really never uploaded?

No. Your browser reads the file from your disk and the tool works on it in the same tab. If you want proof, open your browser's network panel before you drop a file and watch it stay empty.

Why is it free?

Because serving you costs us almost nothing. There is no storage to pay for and no processing to run on our side — the work happens on your device. A small number of unobtrusive ads on some pages cover the rest.

Why does the first load take a moment?

The tool itself has to arrive in your browser before it can do anything. That happens once per tool, and afterwards the page works even without a connection.

Is there a file size limit?

Not one we set. What you can process depends on your own device and how much room your browser has to work in. A phone will tap out earlier than a laptop.

Does it work on a phone?

Yes, for most tools. Small and medium files are fine on a recent phone or tablet. Very large video is still better handled on a desktop.

What happens if I close the tab halfway?

The work stops and the in-progress copy is discarded. Your original file on disk is untouched — a tool only ever writes a new file when you ask it to save one.
