About
Built for the work you're already doing
AT USE is a free set of browser-based tools for image conversion, video metadata, DNS diagnostics, link management, and more. No account. No watermarks. No paywall.
What AT USE is
AT USE is a utility website: a focused collection of browser-based tools that each do one thing and do it well. Convert an image format. Run a DNS lookup. Shorten a URL. Generate a QR code. Extract a video frame. You open the page, drop in a file or enter a value, get your result, and leave. That's the full experience.
The site covers four main areas: image conversion and optimization (50+ format pairs), video metadata and utility tools, network and DNS diagnostics, and link management. We add tools based on real demand, not on what looks good in a feature matrix.
Who it's for
Creators who need a format conversion between takes. Marketers who need an image optimized before a social post goes live. Web developers running a DNS check or validating an MX record mid-deployment. Operations teams who need a WHOIS lookup without installing software. Product designers who need a PNG converted to WebP in 30 seconds, not a 10-minute SaaS sign-up.
If you search for a specific utility tool, use it, and close the tab, this site was built for you. AT USE is not for managing a workflow. It's for people who are already in the middle of one and need one task handled right now.
What makes us different
Most utility tools are either under-powered (browser-side JavaScript with no real processing) or over-demanding (accounts, subscriptions, watermarks on output). AT USE does neither.
Image conversion runs server-side using ImageMagick, the same library professional image pipelines use. Accurate color profiles. Correct transparency handling. Proper metadata on output. The 20 MB upload limit covers real working files, not just demo images.
No account to create. No email to verify. No watermark on the result. No upsell after the first conversion. The tool works the same way the hundredth time as it did the first.
AT USE supports over 50 image format pairs including AVIF, HEIC, TIFF, BMP, ICO, and WebP, formats that many converter tools skip or handle incorrectly. We test output quality, not just whether the conversion completes.
How tools are built
Building a converter that produces accurate output is a different problem from building one that just produces output. Early versions of several AT USE tools ran correctly on sample files and failed on edge cases that real users actually send: HEIC files exported from WhatsApp with stripped EXIF data, AVIF images with wide-color-gamut profiles that clip when downsampled to JPEG's sRGB range, TIFF files from scanner software with non-standard bit depths that confuse color profile engines.
We run our tools against large batches of real-world files whenever we release changes. The 20 MB upload limit is not arbitrary: it covers the 99th percentile of working files that users actually upload. When a conversion fails, the error message describes what went wrong in plain terms, not a stack trace.
Server-side processing means the same ImageMagick version, the same color engine, and the same compression parameters every time. That consistency matters for professional workflows. A product photo converted today should look identical to one converted next month.
The network tools operate on the same principle. Our DNS lookup queries authoritative nameservers directly. Our WHOIS queries hit the registrar's RDAP endpoint. The status checker runs a real HTTP request from our server, not a cached result from an intermediary. The number you see is the number we measured.
How we operate
AT USE is free because it's supported by Google AdSense advertising. No user data is sold. No tracking beyond standard analytics (Google Analytics, Search Console). Files uploaded for conversion are deleted from the server after your session, never stored persistently, indexed, or analyzed.
No dark patterns. No countdown timers. No “premium only” gates on core features. No fake download buttons. No email capture walls. The tool is the product. The ad keeps it free.
New tools ship when they're ready, not on a marketing schedule. If a tool isn't live yet, it shows as “coming soon” with no artificial launch date. If something breaks, we fix it and say so clearly in the error message.
Who's behind it
AT USE was founded and is operated by a small independent team of web engineers and product builders based in Israel. The project grew out of a practical frustration: the best free image conversion and utility tools available at the time either required account creation, added watermarks, ran client-side JavaScript that produced inconsistent results depending on the browser, or capped file sizes so low they were useless for real working files.
The founder's approach was to solve that problem once with server-side processing and no friction: build the tools, put them online, keep them free with advertising rather than subscriptions, and test output quality rather than just whether the conversion completes.
The team is small. We don't have a product roadmap that exists to impress investors. New tools ship when there's real demand for them and when the implementation meets our quality bar. If something breaks, there's a short path from the bug report to the person who can fix it. We check bug reports the same day they come in.
AT USE is self-funded, carries no outside investment, and has no corporate parent. The priorities are: tools that work, output that's correct, and a site that loads fast. Everything else is secondary.
Resources
The AT USE blog covers the practical side of the tools on this site: format comparisons grounded in what our converters actually produce, compression guides based on real upload patterns, and explanations of network and DNS concepts that come up when you're using tools like the status checker or WHOIS lookup.
Articles are written by the people who run the tools and read the conversion logs. If you want to understand why AVIF and WebP produce different results at the same file size, or what actually happens during DNS propagation, the blog is where that work lives.
Questions, bug reports, and feature requests go through the contact form. It reaches a real inbox. We respond.
Built by
The tools at AT USE are built and maintained by two people. Alex Carter builds the developer utilities, format converters, and network tools. Nina Calloway builds the image and video tools.
