AboutAbout Novus Convert
Novus Convert is a free, ad-supported file converter and compressor that processes supported files inside your own browser. It is built and operated by Novus Stream Solutions in London, Ontario, Canada.
01What this site is
Novus Convert converts and compresses files without asking you to hand them to a server. The catalogue documents 274 file formats, 255 of which have a real engine that runs in the browser, and those engines produce 2,400 working conversion routes. There is no account, no upload quota tied to a subscription, and no watermark on a result. If a format appears in the format directory without a converter attached, that is deliberate — it means this release can describe the format accurately but cannot yet produce a valid file in it.
02Why the conversion runs on your device
A conventional online converter is an upload service: your file crosses the network, a server decodes it, and a download link comes back. That model means someone else's disk holds your tax return, your client's artwork, or your unreleased footage — however briefly. Novus Convert inverts it. The decoders and encoders are compiled to WebAssembly and executed inside your browser tab, so the bytes never leave the machine you are sitting at. That is also why there is no upload progress bar, no file-size pricing tier, and no server queue to wait in.
03The engines doing the work
Roughly 40 distinct engine families back the working routes: an FFmpeg build for audio, video, and animation; LibRaw for camera RAW; pdf.js and pdf-lib for documents; SheetJS for spreadsheet interchange; libarchive for RAR, 7-Zip, and friends; Open CASCADE for STEP and IGES geometry; fonteditor-core for typefaces; @jsquash for AVIF and JPEG XL; plus hand-written encoders for images, meshes, subtitles, and structured data. They are downloaded only when a conversion actually needs one, which is why the first HEIC or first video conversion of a session pauses to fetch its engine and later ones do not.
04What we refuse to ship
A conversion route is published only when an engine can produce output that passes a real signature check. Formats that cannot clear that bar — currently 12 of the 274 documented — are published as reference guides with no upload control at all, rather than as buttons that fail after you have waited. The site would look larger if we listed them as conversions. It would also be lying. Verified formats number 255, and the help centre explains what happens when one of them still cannot read your particular file.
05How the catalogue stays honest
Every count on this site — including the ones in this paragraph — is read from a single capability registry when the page is built, not typed into the copy. Two build-time assertions refuse to compile a release where a published route has no implementation, or where a format is missing its written profile. Routes are additionally exercised against pinned real-world fixtures in an end-to-end browser suite; a route without a passing fixture stays unlisted from search rather than being quietly advertised. The changelog records what each release actually changed.
06Who runs it
Novus Convert is operated by Novus Stream Solutions, a sole proprietorship trading as Novus Stream Solutions and based in London, Ontario, Canada. There is no support call centre and no ticket bot — convert@novusstreamsolutions.com reaches the person who writes the code. Bug reports that name the input format, the output you chose, and the exact error text shown under the file are usually reproducible the same day.
07How it is paid for
Advertising, and nothing else. The site shows ads from Adsterra and uses Google Analytics for aggregate traffic, both gated behind the consent control described in the cookie policy. Legal and policy pages carry no advertising at all. File contents and filenames are never shared with an advertising or analytics partner — they never leave the browser to begin with. If a feature ever cannot be funded this way, it will be announced before it changes, not applied retroactively.
08The rest of the toolset
Novus Convert is one of several small, single-purpose tools published by Novus Stream Solutions. They share a design language and the same bias toward doing the work locally where the browser allows it.
