Offloadio — Back up, verify, and organize every shoot automatically

Q: What is Offloadio?

Offloadio is a macOS and Windows app that copies footage off SD and CFexpress cards, verifies every file with a BLAKE3 checksum, and automatically organizes it into named folders as it copies.

Q: Which platforms does it run on?

macOS (Apple Silicon) and Windows. The Windows version is distributed through the Microsoft Store; the macOS version is a direct download.

Q: Does it need an internet connection?

No. Offloadio runs fully offline with no account and no telemetry. The only time it goes online is a one-time license activation.

Q: How much does it cost?

Your first five offloads are free. After that it is a one-time $79 launch price (going up to $119) with no subscription.

Offload + organize

The folders build themselves.

Tell Offloadio how you like a shoot organized — once. Every offload after that sorts by capture time, drops each clip into the right folder, and renames it your way — automatically, while it copies. No Finder cleanup. No dragging. No 1 a.m. renaming.

Sort by capture time

Footage sorts itself by when it was shot.

Name your windows once — “Ceremony,” “Reception,” “Morning Shoot” — and every clip, from every card and camera, lands in the right folder by capture time. Overnight and multi-day events handled.

{window}capture timemulti-day

Zero manual sortingDrop in the cards and walk away — every frame files into its window's folder as it copies.
Save it as a templateReuse a whole set of windows next shoot, or set a default that loads the moment you launch.

Custom folders & filenames

Delivery-ready names on every file.

Build your folder tree and filenames from tokens — date, type, sequence — and watch the live preview update as you type. Every still and clip in the run is named your way, consistently. The Finder rename pass is gone for good.

Multi-card, multi-drive

Every card to every drive, in one pass.

Drop in all your cards and copy to a working drive and a backup at the same time. Each file is read off the card just once, then verified — so it's faster, and gentler on cards you can't replace mid-shoot.

Built on trust

Your footage is irreplaceable. So we never gamble with it.

Other tools race to copy fast. Offloadio is built so the footage that leaves your card is provably identical to what was on it — and nothing it does can ever harm the original.

Your card is never at risk

A write-protection layer refuses any write that resolves onto removable media — even through symlinks. Your card is never modified, renamed, or deleted from.

enforced in code, not by convention

Proof every file made it

Each file is re-read after copying and its 256-bit BLAKE3 hash compared against the source. A mismatch deletes the bad copy and flags the file — so a corrupt copy never hides among the good ones.

BLAKE3 · 256-bit · per file

A crash can't fake a file

Files are written to a temp name and renamed into place only after copy and verify succeed. A power loss, force-quit, or pulled card never leaves a half-file pretending to be real.

How it works

From card to delivery-ready — in four steps.

One pass does the backup and the busywork. Then re-verify months later, with the same engine watching your back.

1

Detect

Insert your cards

Every card is detected automatically, with file counts by type, total size, and the camera identified from the images themselves.

2

Copy & file

Offload and organize

All cards copy at once — to a working drive and backup together — and each clip files into your folders, renamed, as it lands. Each file is read off the card just once.

3

Verify

Prove every file

Every copy is re-read and BLAKE3-compared against the source. A per-file audit manifest and a shareable HTML report land right alongside your footage.

Re-verify

Still good, months later

Point Offloadio at the archive any time and it re-hashes every file against the stored manifest — catching bit-rot or a flaky drive before it bites.

integrity for the long haul

Years from now

Know your footage is still good — long after delivery.

Most tools verify once at copy and forget. Offloadio writes a manifest you can re-check forever, so you can prove a finished archive is still perfect — not just hope it is.

No nasty surprises

It quietly handles everything that can go wrong.

The failure modes that wreck a delivery — full disks, duplicate filenames, half-copied files — are designed out by default, with no extra clicks.

Pick up where it left off

Files already copied are recognized by hash — not filename — and skipped. Re-running an interrupted offload copies only what's missing, instantly.

No file ever overwrites another

Two cameras both shooting DSC0001? Detected and resolved by numbering — never overwritten, never lost, even across many cards at once.

Never fills a disk halfway

Every destination is checked for room before a single byte copies — so an offload never strands you with a half-full drive at the worst moment.

A receipt for every job

A per-file CSV manifest and a clean, shareable HTML report land beside the footage — proof for a client or your own peace of mind. Tuck it away or turn it off.

Eject only when it's safe

Cards auto-eject only after a fully verified, failure-free run. Anything less is reported file-by-file, and the cards stay safely mounted.

Your clients' footage stays yours

No account, no cloud, no network at runtime, no telemetry. Everything runs on your machine, and the footage never leaves it.
