Rabbit Labs

What we make.

Two browser extensions on the Chrome Web Store, and a file converter on the web. The extensions are free, need no account and collect nothing. Filebender is free with an account for a set number of files every day, and deletes your files an hour after converting them.

Browser Extension

Rabbit Ad Blocker

Blocks the ads. Keeps quiet.

A free browser extension that stops ads, trackers and pop-ups before the page can load them. YouTube ads included. No account, no settings to wade through.

One icon in the toolbar and a small panel. It counts what it stopped on the page you’re on, splits that into requests, ad slots, pop-ups and video ads, keeps a running total since you installed it, and stays out of the way the rest of the time.

Add to ChromeSetup and help guide

Out now on the Chrome Web Store, free, with nothing to sign up for.

How it helps

What Rabbit Ad Blocker does.

Ads go before the page draws

Requests get stopped at the network layer, so you never see the gap where the banner was going to be.

Trackers get the same treatment

The scripts that follow you between sites are blocked alongside the ads, because they are usually the same scripts.

Nothing to configure

Install it and it works. The panel is the whole interface: one switch, four counters and a button to pause it on the one site that insists.

Before you install it

What it asks of you.

An ad blocker needs permission to read every page you open, which is a lot to ask. The help page lists every permission it requests and what each one is for, so you can decide for yourself before you install it. The extension also ships unminified, so you can unpack what your browser installed and read it line by line.

Tab Management

Rabbit Smart Tab

Sixty tabs open. Again.

Smart Tab clears the tab bar without losing anything. Save one tab, a whole window, or everything you have not touched in hours, and it closes them and hands the memory back. One click brings any of it back, tab groups included. None of it leaves your browser.

A side panel you open when the tab bar has got away from you. It shows what you have saved, roughly how much memory came back, and a search box for finding the tab you meant.

Add to ChromeSetup and help guide

Out now on the Chrome Web Store, free, and everything it saves stays in your browser.

How it helps

What Rabbit Smart Tab does.

Out of the way, not lost

Save a tab or a whole window in one click. Smart Tab keeps the title, the address and the group it was in, then closes it and gives you the memory back.

Idle tabs tidy themselves

Turn on auto-archiving and anything you have not touched for two hours is saved and closed for you. The tab you are reading and anything pinned are left alone.

Close a window without losing it

Everything you save is searchable and sorted into workspaces, so picking the session back up tomorrow is one click rather than an archaeology exercise.

It all happens on your machine

Titles, addresses and the snippet of page text that makes search work are stored in your browser. Nothing is uploaded, and there is no account.

Before you install it

What it asks of you.

Worth being upfront about this: a tab manager has to read the titles and addresses of your open tabs, and Smart Tab also keeps a short snippet of each saved page so you can search for it later. All of that reading happens inside your browser and stays there. Nothing is uploaded, there’s no account, and there’s no sync server holding a copy of your session. The help page lists every permission and what it is for.

File Converter

Filebender

Any file, into the one you need.

HEIC photos into JPG, several photos into one PDF, a video into a GIF, a PDF small enough to email. Filebender has more than 400 conversions, PDF tools for merging, splitting, turning and removing pages, text from scans (OCR) and trimming for video and audio. It says before you start what a conversion will lose and how big the result will be.

One box to drop files into, a row per file with the format it becomes, and a gear for the details: size, quality, codec, page size. It also opens files straight from Google Drive and saves the results back there. With Add from phone, you can scan a code on your computer and send photos from your phone straight into the converter; they count towards your plan only when they're converted.

Open FilebenderHow it works

At filebender.rabbitlabs.app, with nothing to install. The free plan gives you a set number of files every day, and Day, Week and Month passes add more, each one payment that never renews. Every plan needs an account, which is free to create with Google or your email address.

How it helps

What Filebender does.

Almost any file

More than 400 conversions across images, vector art, video, audio, documents, spreadsheets, slides, ebooks and archives, with resizing and compression in the same step. Compress a PDF, picture or video to the size you choose, such as 5 MB: Filebender aims just under it, or tells you if it can't.

PDF tools and scans

Merge, split and organise PDFs, turn or remove pages, and put several photos into one PDF. Text from scans (OCR) makes a scanned PDF searchable or gives you its words as plain text, and video and audio can be trimmed to the part you want.

On your device where it can be

JPG, PNG and WebP photos, and PDFs you merge, split or organise, can be done in your browser, so those files never leave your device. They still need your account and count towards your plan like any other file.

Gone in an hour

Files sent to Filebender's servers are deleted an hour after they're converted, or the moment you press Delete, and photo location is removed by default. A file converted there can go straight to your phone: scan the code to download it. The code works for 10 minutes.

Before you use it

What it asks of you.

Unlike the extensions, Filebender mostly needs a server: most files are uploaded to Rabbit Labs' servers on Google Cloud, converted there in locked-down containers with no internet access, and deleted an hour later. Nobody looks at them. Photos converted in your browser, and PDFs you merge, split or organise, aren't uploaded unless you ask for a damaged PDF to be repaired: Filebender only counts them against your account's plan, by type and size. Filebender's privacy policy has the details, including what your account and any pass you buy keep, and for how long.

How we work

The same rules for everything we ship.

No subscriptions

The extensions are free, with no pro tier waiting in the wings. Filebender has a free plan too, with an account and a set number of files every day, and its Day, Week and Month passes are for when you need more files, more videos or bigger files. A pass is one payment and never renews.

We keep only what we need

The extensions collect nothing: no browsing data, no usage stats, no crash pings. Filebender needs a server to convert files, deletes them an hour later, and keeps only what it needs to run your account and any pass you buy.

You can read the code

Nothing we write is minified or obfuscated. Unpack the extension your browser installed and read exactly what it does. Filebender's own page scripts are unminified too, and the libraries it uses to convert files in your browser are listed with their licences on its third-party notices page.

As little about you as possible

The extensions need no account and no email address. Filebender needs an account, with Google or with your email address and a password. It keeps your name and email address (and what Google sends, if you use Google), a log of when you signed in, and a record of any pass you buy. Your card details go to SumUp, never to us.

What’s next

There’s more coming, slowly.
