Convert and compress images, look up DNS records, trim audio, extract video frames, and run dozens of other everyday tasks — directly in your browser, with no account and no install.
Every small task you keep opening a desktop app for — resize an image, check a DNS record, strip EXIF data, trim an audio clip. Done in the browser. Free.
AT USE is a collection of more than 30 browser-based tools built for creators, marketers, and product teams who need to get things done without installing software or signing up for a SaaS subscription. Image processing runs server-side via ImageMagick. DNS and network tools query live servers — no cached results. Video and audio tools run in-browser via WebAssembly.
Tool categories cover what comes up most in a real workflow: image conversion and compression, video and audio utilities, network and DNS diagnostics, and developer helpers like JSON formatting and JWT decoding. Every tool is free, works on any modern browser, and needs no account.

No. Every tool on AT USE is available without creating an account or signing in. Open the tool page, run your task, and download the result. There are no paywalls, no email gates, and no trial limits on any of the listed tools.
Files you upload are processed only for your session and are never shared. Image and audio processing runs server-side using temporary storage that is automatically cleared after your download is ready. We do not use your uploaded content to train models or share it with third parties. For complete details see the Privacy Policy.
AT USE is free to use. The site is supported by non-intrusive Google AdSense ads — there are no subscriptions, no premium tiers, and no hidden paywalls on any tool. If you block ads, the tools still work.
AT USE supports JPG, PNG, WEBP, AVIF, BMP, TIFF, HEIC, ICO, and SVG. The image converter handles 72 format-pair combinations — for example JPG to WEBP, PNG to AVIF, HEIC to JPG, and BMP to PNG. The image optimizer compresses and resizes any of these formats server-side using ImageMagick.
Image tools accept files up to 20 MB per upload. Audio converter tools accept files up to 50 MB. Video tools that run in the browser (trim, compress, frame extract) work with whatever your browser can load — typically several hundred MB. Batch operations allow multiple files in a single run.
Nothing to install, nothing to update. AT USE runs entirely in your browser so it works the same on Windows, Mac, Linux, and mobile. You do not need to subscribe, create a workspace, or manage software licences. For one-off tasks — converting a file, looking up a DNS record, trimming an audio clip — opening a browser tab is faster than any alternative.

The Network & DNS category includes DNS lookup (A, AAAA, MX, NS, TXT, CNAME, SOA, CAA records), reverse DNS, WHOIS, propagation checker, blacklist check, online status checker, TCP port checker, SPF record checker, and DMARC record checker. All checks run against live servers — no cached results.
