Who we are, why we process your files inside the browser without uploading them to any server, which tools we offer, and how the project sustains itself.
Modern tools for optimization and digital document management.
At BawiTools we develop solutions focused on efficiency, privacy and performance. Our mission is to simplify file management without compromising data quality or security.
BawiTools is a project developed by engineers focused on creating fast, reliable and accessible digital tools. We specialize in document optimization and efficient processing directly from the browser.
We bet on modern solutions that eliminate the dependence on heavy software, offering a lightweight and direct experience for the user.
The starting point was a specific and very common annoyance: for everyday tasks — shrinking a PDF that will not go through email, converting an image because a portal only accepts JPG, trimming thirty seconds off a video — the usual answer is installing a desktop program that takes hundreds of megabytes, or uploading the file to an unknown server and trusting that it gets deleted.
Neither option seemed reasonable to us for something the browser can already do. Today's browsers include everything needed to decode images, process audio and video and manipulate documents without leaving the tab. BawiTools was built on that idea: let the tool go to the file, rather than making the file travel to the tool.
To provide digital tools that allow anyone to optimize and manage files in a simple, fast and secure way, without the need for advanced technical knowledge.
In practice that translates into three commitments that shape every product decision. The first is that there are no barriers to entry: no tool asks for registration, an account, or personal data in order to work. You open the page, drag your file in and get on with it.
The second is that the tool should explain what it does. Every page includes a guide to the relevant format or operation, because we believe that knowing why a PNG weighs more than a JPG, or why compressing a text document barely reduces its size, is as useful as the convert button. The third is that the result should be predictable: same files, same outcome, no surprises and no watermarks.
To become a leading platform in web tools for digital productivity, standing out for performance, simplicity and a focus on privacy.
We want local processing to stop being the exception and become what people expect by default from a web tool. Uploading a private document to someone else's server for a trivial task should be seen for what it is: an unnecessary risk when an alternative exists that does exactly the same thing without the file ever leaving your device.
There are plenty of file tools on the internet. These are the concrete decisions that set us apart from most of them:
Local processing in the browser: your files are opened, transformed and downloaded without leaving your device. There is no upload to a server, and therefore no copy anyone has to promise you they will delete afterwards.
High performance and efficient optimization: with no network transfer involved, waiting time depends solely on your own machine. A large file is not slower because your connection is, and there are no queues or hourly usage limits.
No registration or mandatory accounts: no tool asks for an email, a password or personal data to work. We also do not impose watermarks or hold back features to push you toward a paid tier.
Modern and easy-to-use interface: each tool does one specific thing and explains it on its own page, with the minimum necessary jargon.
Focus on privacy and security: because we never receive your files, we cannot analyse them, keep them or pass them to third parties. Privacy here is not a promise in the privacy policy, it is a consequence of how the tool is built.
The catalogue brings together 33 tools organised into five categories, all free and all using the same local processing model:
Converter: conversion between the common image formats — JPG, PNG, WebP, AVIF, GIF, BMP, TIFF and ICO — plus image to PDF and PDF to image.
Compressor: size reduction for PDF, Word, Excel, PowerPoint, images and video, matching quality to what you will actually use the file for.
Multimedia: video and audio trimming, conversion between video and GIF, extracting the audio from a video, and merging, trimming and changing the speed of GIFs.
Developers: JWT debugger, Base64 encoder and decoder, and a formatter for JSON, XML, YAML and CSV.
AI: image upscaling and automatic background removal, with the models also running in your browser.
When you drag a file into one of our tools, the browser reads it from your disk into the tab's memory. From there all the work happens inside it, and the result is offered to you as a locally generated download. At no point in the process is there a network request containing your file.
To achieve that we use the capabilities the browser itself exposes. Image conversions rely on the decoders and encoders browsers already ship with. The video, audio and GIF tools run a version of FFmpeg compiled to WebAssembly — the same engine behind a great many desktop applications — inside the tab. The AI features load their models onto your machine and run inference locally.
This carries an honest trade-off worth knowing about: speed depends on your computer or phone, not on our servers. A long video on a modest machine will take a while. In exchange, there is no daily file limit, no waiting queue, and your contract, your invoice or your personal photos are never copied to a machine you do not control.
It also means the first load of some tools downloads the components they need — the video engine and the AI models are not small. That is a cost you pay once, after which it stays in the browser cache.
BawiTools is built with modern technologies such as React, client-side optimization and performance-focused architectures, allowing complex processes to run directly in the browser.
The site is generated as static pages and only loads interactive code where it is genuinely needed, so the content is available from the server's first response and the tool activates afterwards. It is available in Spanish and English, with its own addresses for each language.
Heavy processing relies on WebAssembly, which lets compiled code run in the browser at close to native speed. That is what makes it viable for tasks which a few years ago demanded an installed program — transcoding video, applying a super-resolution model to an image — to work in a tab today.
BawiTools is free and has no paid tier, no plans and no locked features. We would rather say openly how it is funded than leave it to the imagination.
The site is supported by advertising and by voluntary donations from anyone who wants to contribute. Ads are blocks clearly separated from the content, and they are never served on the basis of your files — quite simply because we never receive them: advertising has no way of knowing what you are converting or which document you compressed.
We use first-party and third-party cookies for analytics and advertising, and we ask for your consent before enabling any that are not strictly necessary. You can accept them, reject them or customise your choice at any time from the cookie preferences link in the footer. The details are in our cookie policy and our privacy policy.
If you want to contact us for suggestions, support or collaboration, write to us. We read every message: bug reports, formats you find missing, tools you would like to see, or any problem with a specific conversion. If you are writing about a fault, telling us the file type and the browser you use saves us a good deal of time.
