A new way to find
what gets it done.

Version 5.0.0 rethinks the path from opening the app to finishing a task. A new identity, clearer navigation and room to work.

Find it in a few keystrokes.

Search tools and actions with Ctrl + K, in English or Portuguese. Accents and word order won’t get in your way.

Keep your tools in reach.

Explore tools and actions in the new sidebar. Pin your favourites and work in full pages, with a clear path back.

Start with your file.

Drop a file on the home page to discover tools that can open it. Hover a card to preview the tool in action.

Everything follows your work.

Queue, history, settings and quick tools share the new design. Leave a tool’s page and its job keeps running in the queue.

Try it before
you install.

An imitation of the app with three ready-made walkthroughs. Click, drag and type: the list beside it keeps up with you.

Pick the result.
Not the binary.

The catalog is organised by what you want to end up with: merge these PDFs, pull the audio out of this video, shrink this image. The tool that does the work is an implementation detail, named on the card for when you care. Every one of them is listed in the full catalog below.

Before

$ ffmpeg -i lecture.mp4 -vn \
  -c:a libmp3lame -q:a 2 out.mp3

Remember flags, paths and quoting.

With Tools4Devs

You pick the result. The app builds the command.

  1. Drop or search

    Drag a file onto the home page, or press Ctrl + K and say what you want to do.

  2. Pick the result

    Extract audio, merge PDFs, shrink an image. The card shows which tool does the work.

  3. Follow it in the queue

    The job runs on your machine and keeps going in the queue even if you leave the page. The finished file is one click away.

It brings its own tools.

Nine tools travel inside the installer. The others download on first use, checked against a pinned SHA-256 before anything is unpacked, and activated by an atomic rename so a failed install never leaves half a tool behind. Everything lands in your own user folder, so Tools4Devs never needs administrator rights.

Six seconds per tool. All twenty-five are open source: no fork, no rewrite, no wrapper pretending to be the original. Tools4Devs runs the upstream binaries with an argument array, never a shell string, and the licence of every one travels with the installer.

Your files stay
where they are.

No account

No sign-up, login or subscription. Install and use.

No telemetry

No usage is reported and nothing about you is collected.

It all runs here

Every operation is a local process, on a file that stays where it is.

AI models run on your computer too. OCR and the photo upscaler are downloaded only if you ask, and your picture never leaves the machine.

Some tools need the internet, like downloading a video, searching by image or identifying a song, and each one tells you before it runs. Beyond that, the app only checks for updates and downloads the components you ask for.

The things people ask first.

Do I need to install FFmpeg, Python or anything else first?

No, nothing at all. Nine tools travel inside the installer and seventeen more are downloaded by the app on first use, each checked against a pinned SHA-256, with the size on screen before the download starts. The quick tools are part of the app itself. Nothing ever asks for administrator rights.

Does it update itself?

Yes. It checks for a new version when it opens, downloads it and installs it. It stops short of restarting itself, because a window that vanishes mid-job is not helpful, so the last step is a button. Every update is checked against a signature before it is allowed to run, so a tampered download is refused rather than installed. The portable build does not update itself, because there is nothing installed for it to replace.

Where does a finished file go?

Where you chose, or into the default folder set in Settings. Every finished job in the history has two buttons: one opens the folder with the file already selected, the other copies the path.

What are the quick tools?

About ninety small tools built into the app, with results as you type: change case, Base64 and hashes, date math, finance and health calculators, colour conversion, CSS generators, CSS and HTML minifiers, QR codes and barcodes, dice and raffles, and test data such as CPF, CNPJ and sandbox card numbers. There are also chat and post mockups, which turn a conversation or a tweet you type into an image.

What languages does it speak?

English and Brazilian Portuguese, chosen in Settings and remembered on the machine. The whole interface is translated, not only the menus: every tool, operation and option, the hints, the errors and the queue.

Does Tools4Devs need administrator rights?

No. Downloaded tools install into your own user folder under %LOCALAPPDATA%, so no elevation prompt is ever required.

Does it work offline?

Every operation on a file runs as a local process on your machine, so the converting, cropping, trimming and reading all work offline, and so do the quick tools. What needs a connection is what obviously would: downloading a video, fetching a tool you asked to install, a reverse image search, naming a piece of music and the three network lookups.

Is any of my data uploaded or tracked?

Nothing about you is collected (no telemetry, no analytics, no account), and your files stay where they are. A few tools send something out on purpose, and each says so before it runs: a reverse image search uploads the picture you picked, music recognition sends a fingerprint of a clip rather than the sound, and the network lookups ask a public service. See the privacy section.

Why does Windows SmartScreen warn me when I run the installer?

The installer is not code-signed yet, so SmartScreen shows an unrecognised-publisher warning on first run. SHA-256 checksums are published with every release so you can verify the download yourself.

Can Tools4Devs read text from scanned PDFs and images?

Yes. Tesseract reads text out of a picture or a scan, either into a text file or back into the PDF as a searchable layer behind the image. It is a neural network, it runs on your CPU, and it is downloaded only when you ask for it. Nothing is sent anywhere.

Start with Tools4Devs 5.0.0.

Choose your format on the 5.0.0 release page on GitHub. No account, no subscription and no tools to set up by hand.

Windows 10 and 11, 64-bit. SHA-256 checksums are published with every release. The installer isn't code-signed yet, so SmartScreen will warn on first run. More on that in the FAQ.
