A complete inventory of what Novus Convert does today: 255 browser-ready inputs, 2,400 conversion routes, batch queueing, same-format compression, signature-validated exports, and offline use.
Last updated: August 7, 2026
274 formats are documented, 255 of them convert locally, and together they produce 2,400 working routes. By category the catalogue is Data 61, Document 51, Archive 39, Image 37, Vector & CAD 35, Video 19, Audio 16, Ebook 9, Font 7. Every one of those figures is computed from the capability registry when this page is built, so it cannot describe a library the site no longer has. Browse them in the conversion directory or the format directory.
Drop in a mixed batch — a RAW photo, a video, a spreadsheet, an archive — and choose a different output for each row. The available outputs for a row come from the file's real signature and your browser's capabilities, never from its extension, so a mislabelled file is caught before conversion rather than after. Start at Convert.
Same-format compression re-encodes a file into a smaller version of itself: images and media at an adjustable quality, PDFs, ZIP-family packages, fonts, meshes, and text-like formats through their own paths. The saving is measured against the original and shown before you download, so a re-encode that would make the file larger is visible instead of silent. Start at Compress.
The queue runs conversions with a bounded concurrency — one at a time on mobile or memory-constrained devices, two elsewhere — so several WebAssembly decoders cannot exhaust the tab. Individual jobs can be cancelled mid-run, removed, or cleared entirely, and a cancelled job aborts the underlying worker rather than merely hiding its row.
Every result is inspected for the real container signature or decodability of the format you asked for. A failed encode therefore cannot be saved as a broken file wearing the right extension — the download simply does not enable, and the row reports what the engine actually said.
Finished results download individually, or several at once as a ZIP that also contains a manifest listing each file's output format, MIME type, byte size, and SHA-256 digest. The manifest is generated in the browser alongside the files it describes, so it can be used to verify a batch after the fact.
Images and Office or ebook inputs are capped at 100 MB, decoded images at 80 megapixels, PDFs at 150 MB, media at 500 MB, fonts at 50 MB, and structured text at 25 MB. Archives and 3D or comic packages are capped at 200 MB, and additionally at 5,000 entries and 512 MB expanded — the limit that stops a decompression-bomb archive from taking the tab down with it. The help centre lists the daily per-format export allowances alongside them.
Each of the 274 formats has its own page covering what the format is, where it came from, its technical characteristics, realistic use cases, honest pros and cons, and compatibility notes — including for the guide-only formats this release cannot convert. Those pages are generated from structured data rather than written twice, so a format's facts stay consistent everywhere they appear.
Each of the 2,400 working routes has its own page with an introduction, a reason to make that specific conversion, a from/to trade-offs table, step-by-step instructions, and a FAQ — composed from the two formats' profiles so no two routes read the same. Routes that are implemented but not yet fixture-verified stay out of search results until they are.
A complete tutorial walks through conversion, batches, compression, downloads, and mobile use; the documentation covers how local processing and validation work; the help centre answers the specific failures people actually hit; and the blog publishes original format guides and comparisons.
Novus Convert can be installed as a standalone progressive web app on desktop and mobile. A service worker caches the interface and any conversion engines you have already used, so after one online visit those tools keep working with no network at all — which is exactly the case a browser-local converter should handle and an upload service cannot.
Every primary workflow is reachable without a pointer, with visible focus and a logical order; file status, progress, errors, and validated downloads are announced to screen readers. The interface respects reduced-motion preferences, avoids relying on colour alone for status, and ships a light and dark theme. Details are on the accessibility page.
Advertising and analytics storage start denied. Where prior consent is legally required they stay denied until you accept; everywhere else the banner is how you turn them off, and rejecting removes the scripts that had already run. A browser Global Privacy Control signal always keeps advertising and analytics off. The choice is reopenable at any time from Manage cookies in the footer. The privacy policy and security page describe the rest.
