About Convilyn — Convert on Download
Convilyn converts and compresses files in your browser, at the moment you
already have them — on the way in, on the way out, and in between.
Convert a download as it arrives
A .webp Word will not take. A .heic your printer rejects. A PDF you needed as
text. Convilyn notices the download and offers to convert it right there: the
download pauses, you pick a format, and the original is discarded only once the
converted file has actually arrived. If anything fails, you keep the file you
started with.
Fix a file a form refuses — before you give up on it
You attach a résumé and the application form rejects it: wrong format, no
explanation. Right-click the page and Convilyn reads what that file field
actually accepts, converts your file to match, and hands it back to the form.
Nothing else on the page is read, and the access ends when you navigate away.
PDF tools, without a round trip to a website
Extract the text. Export pages as images. Rotate, compress, pull out a page
range, or split a document into one PDF per page.
A tray for the pile
Receipts across five tabs, invoices from three billing portals, images from a
product page: right-click to add each to the tray, then convert, compress, or
download the whole pile as one ZIP. The tray survives tab closes and browser
restarts, and a file you have already collected is uploaded once, however many
operations you run on it.
Where the file came from, shown
A browser is the only place a file still carries its context. Convilyn shows the
source site next to the filename, so you always know what you are converting.
Your account, your key
Connecting takes one click and no password. The site mints an API key for this
browser that can do only what the extension needs — upload a file, run a
conversion, fetch the result. You can revoke it at any time from your account,
and uninstalling opens the page that revokes it for you. Files are processed on
Convilyn's servers and swept shortly afterwards.
Interface available in English, 繁體中文, 简体中文, 日本語 and 한국어.
Requires a free Convilyn account. Chrome 116 or newer.
