Large File Transfer Built for Repeat Delivery

Most "send large files" tools are built for a single hand-off and nothing after it. Filemail lets you upload files free up to 5 GB, pCloud Transfer sends up to 5 GB with no registration, and Wormhole does simple, private, end-to-end-encrypted sharing with expiring links — all excellent when you need to fire one file across once and forget it. But every one of them treats the file as disposable: it lives for a few days, then it's gone, and there's nothing to reuse, embed, or automate.

If you deliver files to clients, customers, or your own app over and over, that one-off model quietly becomes the bottleneck. files.link is built for the repeat case — you upload a large file once, get a fast, permanent CDN download link, and keep the file in reusable storage instead of re-uploading it for every send.

The delivery is the differentiator. A public large file gets a permanent, edge-served CDN URL the moment the upload confirms, so a 2 GB installer, a video master, or a design archive downloads from the nearest edge instead of a single origin server — the same delivery the file storage with CDN and file to link pages cover in depth.

When a send should not live forever, a private file is never given a public URL at all: your backend mints a cryptographically signed link on demand that defaults to a 10-minute window and can stretch to 7 days, then stops working when the clock runs out (the temporary file hosting page walks the expiring-link mechanics).

No recipient ever creates an account — the deliberate contrast with Dropbox, whose large-file shares can drop a recipient onto a login or "request access" wall — and there are no ads on the download page.

Because every transfer is the same three-call REST upload — POST for a presigned URL and id, PUT the bytes, POST to confirm — a backend can turn a finished render, an export, or an invoice into a shareable link in one workflow step, the way file.io exposes an API for programmatic sharing but without the single-download self-destruct. That makes files.link a fit for software and media distribution, client deliverables, paid digital downloads, and app-generated links (see the file sharing and files SDK surfaces, and the upload a file guide for the full flow).

Pricing is prepaid credits with no subscription and no per-seat plan: you pay only for the storage and bandwidth you actually use, so a heavy delivery month costs more and a quiet one costs less, with nothing auto-renewing. Honest fit check — if you send one big file a year, a free one-off transfer tool is genuinely the right call; files.link earns its keep when large-file delivery is a recurring part of how you work.
