Free online tools for images, DNS, video, and audio
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.
Flagship tool
Image Optimizer
Compress, resize, convert, and clean backgrounds with queue-backed processing.
Compress JPG, PNG, WEBP and AVIF files with an adjustable quality slider — typically 60–85% smaller with no visible loss.
Resize to exact pixel dimensions, a percentage of original size, or a bounding box that preserves aspect ratio.
Convert & clean — switch format, remove background, and strip EXIF metadata in the same operation.
Batch process multiple files in one run — download results individually or as a ZIP archive.
Compress portfolio images before uploading to your site, batch-convert RAW or HEIC photos to JPG or WEBP for delivery, remove backgrounds for product shots, and prep social-ready thumbnails at the right dimensions — all without leaving the browser or installing anything.
Look up DNS records to verify propagation after a domain move, check SPF and DMARC configuration before a cold-email campaign, confirm a site is reachable from outside your network, and convert images to WEBP or AVIF for better Core Web Vitals scores — one tab, no accounts.
Run a quick DNS or WHOIS lookup during an incident, extract a frame from a screen recording, decode a JWT token, validate a JSON payload, or convert an audio file format — tasks that take one minute and do not need a dedicated tool installed on every machine.
AT USE covers 375 free tools across 10 categories — from image format converters and file compressors to DNS lookups, audio conversion, and video editing utilities. All tools run in your browser with no login required.
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.
Are my files private — who can see what I upload?
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.
How much does it cost?
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.
What image formats does AT USE support?
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.
Can AT USE tools handle large files?
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.
Why use AT USE instead of a desktop app or paid SaaS?
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.
Does AT USE have DNS and network tools?
Yes. 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.
