About Malfen
Malfen is a collection of 25 everyday utilities that work in a browser tab. There is no software to install, no account to create and no trial that runs out. Open the tool you need, do the job, close the tab.
Why it exists
The common way to compress an image or merge two PDFs online involves a download, an installer, a registration form, a watermark, or a progress bar that is padded out to make a free tier feel slow. None of that is necessary. Modern browsers can decode images, rewrite PDF documents and generate QR codes on their own — the work does not need a server at all.
So we built the site around that. The overwhelming majority of the tools here process your files locally, which makes them faster, more private and cheaper to run all at once. It is one of the rare cases where the honest approach is also the efficient one.
How the tools work
When you drop a file onto one of these tools, it is read into your browser’s memory and processed there — using the same canvas, cryptography and document APIs that any web application has access to. No upload request is made. You can verify that yourself: open your browser’s developer tools, switch to the network tab, and process a file. Nothing goes out.
A practical consequence is that the tools keep working without a connection once the page has loaded, and that there is no file size limit imposed by us — only the limits of your own device.
What we will not do
- No login wall in front of a tool.
- No watermark on anything you produce.
- No misleading download buttons or fake progress bars.
- No forced newsletter sign-up before showing a result.
- No collecting your files, your text or your email address.
How it is paid for
Advertising, placed away from the tool interfaces so it is never mistaken for a button. Some articles may link to products we think are genuinely worth recommending. Nothing you need is ever locked behind a payment.
What is next
The site is built as a platform rather than a pile of separate pages, which means a new tool is a configuration file and a component — everything else (search, categories, structured data, the sitemap) follows automatically. The goal is to keep growing past 25 tools across the 9 categories without the experience getting any heavier.
