About IntactFile

What IntactFile is

IntactFile repairs corrupted files — video (MP4, MOV, MKV, WebM), PDFs, ZIP/RAR/7z archives, Office documents (DOCX, XLSX, PPTX), JPG and PNG photos, and SQLite databases — directly inside your browser tab. A damaged file is usually intact data trapped inside a broken structure: an index that was never written, a directory truncated mid-download, a cross-reference table that got mangled. IntactFile reads what survived and rebuilds the structure around it, then hands back a working file. Diagnosis is free for every file, so you can see what's wrong before deciding whether a repair is worth it.

How it works — and why nothing is uploaded

The repair engines run on your own machine, compiled to WebAssembly and TypeScript and executed inside the page. Your file is opened locally, parsed locally, and rebuilt locally. It is never uploaded — there is no server that receives files, so there is nothing for anyone to store, leak, or subpoena. This isn't a privacy policy you have to trust; it's a property you can verify in under a minute. Open your browser's DevTools, watch the Network tab during a repair, and you'll see zero outbound requests carrying your file. For contracts, medical scans, payroll spreadsheets, or footage that simply shouldn't land on a stranger's server, that difference is the whole point — and for multi-gigabyte recordings, uploading was never practical anyway.

Why it exists

IntactFile started with a lost recording. A capture was interrupted, the file wouldn't open, and every "online repair" option wanted the footage uploaded first. Handing irreplaceable material to an unknown server and then waiting for it to come back felt wrong — and for large files, was barely possible. The engines that fix these problems can run on the user's own device, so that's where IntactFile puts them.

How repairs are checked

Every repair runs in the same order, and the order is built to keep you from paying for a result that doesn't work. Diagnosis comes first and is free for every file: before anything is rebuilt, IntactFile reads the damaged file and tells you what's actually wrong — a missing index, a truncated download, data that was overwritten — so you learn whether a repair is even possible before deciding anything. When a rebuild runs, the result is verified against the file format's own structural rules; a file that fails that check is reported as a failure rather than quietly handed back, and you're never charged for one that fails. Where only part of a file can be saved, that result is labelled as partial rather than dressed up as a clean fix — because for an irreplaceable file, an honest partial recovery is often the outcome that actually matters.

None of this is a claim you have to take on faith. We measure it and publish the numbers: a200-file repair benchmarkreports the real success and usable rates for each file type — including the formats that recover poorly — run through the same code the product ships. If you're weighing whether a repair is worth attempting, that page is the honest starting point.

How it's paid for

IntactFile is sustainable without selling data, because there is no data to sell. A free tier covers small everyday repairs — a few per day, no account required. Larger or more frequent jobs are covered by paid credit packs and subscriptions, priced per repair, and a repair that fails verification is never charged. Ads on this marketing site help fund the free tier; they never touch your files, which are only ever handled locally, in your browser.

What it can't do

IntactFile does structural repair, not resurrection. It rebuilds the scaffolding around data that survived — so when the underlying data is genuinely gone (overwritten, zeroed, or never written to disk), no tool can invent it back, and IntactFile will tell you so rather than pretend. It is not data-recovery software for a failing drive or a deleted file; it works on a file you already have that won't open correctly. Results depend on how a file was damaged, which is exactly why diagnosis is free and comes first.
