What "free offload software" actually has to do

Offloading a card is more than copying it. A real offload does three things: it copies every file off the card to safe storage, it verifies the copy by reading it back and comparing checksums (so a silently dropped or corrupted frame gets caught), and ideally it organizes the result so you can find clips later. Plenty of free tools do one or two of those. In 2026 a handful of free apps finally do all three, and only one of them also makes the off-site cloud copy. So the ranking isn't about "they're all the same"; it's about how much of a true offload each one covers without you paying.

Everything below is dated to October 2026. Tools and prices change, so check each project's own site before you rely on a detail.

1. Copsy — free, verified, and it backs up to Google Drive or Dropbox

Copsy — a free Mac camera-offload app — is first here because it's the only free app we found that adds the off-site cloud copy to a verified offload. Plug in an SD, CFexpress or camera card and Copsy auto-detects it by content (Sony, ARRI, RED, Blackmagic, Canon, Nikon, Fujifilm, Panasonic, GoPro, Insta360, DJI drones, audio recorders), copies the footage to an external drive, verifies every file with ASC-MHL checksums (the film-set / Netflix-delivery standard), then uploads that verified copy to Google Drive or Dropbox in the background while you load the next card. Uploads pick up where they stopped after a dropped connection or a restart. It organizes by date and source, writes a PDF report, and pings you on Telegram when it's done. No signup, no card limit, free.

Honest limits: Copsy is macOS-only (macOS 13+) for now, and its Mac app isn't notarized yet, so the first launch needs Open Anyway in System Settings. It mirrors to a second drive after the first copy rather than writing several drives at once, and it doesn't try to be a full DIT cart like Silverstack. If you need Windows, LTO/LTFS, or a deep clip-library/QC pipeline, a paid tool fits better. For "copy a card safely and put it in two places, one of them off-site," Copsy is the free pick.

2. Stow — free, signed, writes several drives at once (no cloud)

Stow from Lumira Studio is free with no trial, no account and, per its makers, no paid tier planned. It reads the card once and writes to all your destinations at the same time, verifies with xxHash3-128, writes an ASC-MHL v2 manifest, reads the camera from the card, and gives you a one-page report that prints straight to PDF plus a checksums.csv. It can send an optional phone alert through ntfy, and it's signed and notarized on Mac and Windows.

Honest limits: no cloud destination: in its own words, your footage never leaves the computer. Cloud destinations sit on its roadmap as "being looked at, not promised". The Mac build is Apple Silicon only, with no Intel version. If you want several local drives filled in one pass, it's an excellent free choice.

3. BitMatch — free and open-source (MIT), SHA-256

BitMatch is a free, MIT-licensed Mac app that reads the card once and writes to every drive at the same time. It verifies with SHA-256, with a Thorough mode that adds MD5 and a Paranoid mode that compares byte for byte, writes ASC-MHL inventories, recognizes Sony, Canon, ARRI, RED, Blackmagic, Panasonic, Fujifilm, GoPro, DJI and Insta360 cards, and exports PDF, CSV and JSON reports. It's signed and notarized, and on Mac it can send an extra off-site copy over SFTP once the local copy is verified.

Honest limits: it needs macOS 15.5 or newer, it doesn't upload to Google Drive or Dropbox, and it's very new: 15 releases between 21 September and 22 October 2026, so expect things to move.

4. Ingesto — free, open-source, cross-platform (no cloud)

Ingesto is free and open-source (GPL v3) and runs on macOS, Windows and Linux. It makes bit-for-bit verified copies with xxHash64, xxHash128 or MD5, writes ASC-MHL v2 (since version 2.5.4) as well as classic MHL, auto-detects the camera brand and model, copies to several drives or network shares in one pass, and writes reports in HTML, CSV and JSON. Since 2.5.5 the Mac app is signed and notarized by Apple, and it can push a phone alert per card through ntfy.

Honest limits: no cloud destination like Google Drive or Dropbox, so an off-site copy is a separate step. Version 2.8.0 needs macOS 13 on Apple Silicon. It's a solo open-source project on GitHub. If you want open-source or Windows/Linux it's the pick; if you want the cloud copy, Copsy fits better. Full Copsy vs Ingesto comparison →

5. FilmCan — free, open-source (GPL-3.0), Intel and Apple Silicon

FilmCan is free (donations welcome), open-source under GPL-3.0 and a universal Mac app for macOS 13 Ventura or later. It copies to several destinations in a single pass, verifies with xxHash128 in a Fast mode or a Paranoid mode that re-reads everything, writes ASC-MHL manifests checked against the reference ascmhl tool, and can notify you through ntfy or webhooks.

Honest limits: transfers stay local, with no uploads. The app is ad-hoc signed rather than notarized, so the first launch needs Open Anyway (or right-click → Open on macOS 13–14). You tag each source as Camera or Sound yourself; only sound drives are auto-detected.

6. DaVinci Resolve "Clone Tool" — free, verified, drive-to-drive

If you already have DaVinci Resolve (the free version is genuinely free and excellent), its Clone Tool on the Media page is a solid free offloader. It makes a checksum-verified copy of a card or mag (MD5 by default, with SHA-256 and other options) and can write to more than one destination at once, with an error warning if a checksum doesn't match. That's a real, verified offload, for free, from software a lot of editors already run.

Honest limits: no auto-detection of card type, no copying to cloud (Google Drive / Dropbox), and you have to launch a full NLE and switch to the Media page just to copy a card. It's drive-to-drive only and there's no Telegram-style "it's done" notification. Still, as a free, verified drive copy it's a strong number two, and a perfectly good answer on its own if Resolve is already open.

7. MhlFileVerify — free and open-source, but verify-only

MhlFileVerify (open-source, GPL-3.0, built on Pomfort's reference MHL tool) is free and useful, but it's important to be clear: it does not copy. It verifies or "seals" files against an MHL hash list (MD5, SHA1, xxHash, xxHash64), which is exactly what you'd use to re-check a backup that another tool (Resolve's Clone Tool, Silverstack, Hedge) already made with an MHL. Drag-and-drop a folder, pick the hash type, confirm everything matches.

Honest limits: because it can't do the copy, it isn't a standalone offloader. Think of it as the verification half of the job, paired with a tool that does the copy. Great free safety net, not a one-stop offload.

8. Terminal md5 / shasum — free, manual, no GUI

Every Mac ships with checksum tools in Terminal. You can cp -R a card, then run shasum -a 256 (or md5) on the source and the copy and compare the hashes by hand. It's completely free, it's bit-accurate, and it's a legitimate verification method if you're comfortable in a shell and scripting a loop over every file.

Honest limits: no GUI, no card auto-detection, no parallel cloud copy, and it's easy to make a mistake at 2am. Forget a folder, compare the wrong files, or skip the verify entirely. It's a great "I know exactly what I'm doing" fallback, not a workflow you'd want to run every shoot. For most people a GUI offloader removes the human error.

9. Plain Finder drag-and-drop — free, but NOT verified (risky)

Dragging the card's folder into a drive in Finder is what a lot of people actually do, and it's the one approach this roundup recommends against for camera footage. Finder copies the bytes, but it does not verify them: there's no read-back, no checksum, no warning if a frame silently drops or a file corrupts mid-copy. You find out in the edit, after the card is already formatted. It's free, but "free" isn't the point when the footage is irreplaceable. If you take nothing else from this page: don't format a card after an unverified Finder drag.

The free options, compared

Features were last verified in October 2026 and can change, so check each project's own site for current details. Copsy is the only free entry that backs up to Google Drive or Dropbox; Stow and BitMatch are the strongest free multi-drive offloaders; Ingesto is the strongest cross-platform one; DaVinci Resolve's Clone Tool is a fine verified copy if Resolve is already open.

Where the paid tools fit (so this stays honest)

Free isn't always the answer, and the paid incumbents are good for real reasons. OffShoot (the rebranded Hedge, roughly $169–$249) is mature, fast, ASC-MHL-compliant and runs on Mac and Windows, trusted on big productions. ShotPut Pro (around $169 plus an annual update plan) is a long-standing "industry standard" with PDF reports and an iOS monitoring companion. Pomfort Silverstack (a yearly subscription) is full DIT software with a clip library, QC, LUTs, and deep ASC-MHL reporting. It's powerful, with a steep learning curve. Others people weigh include YoYotta (around $110/yr). If you need Windows, LTO/LTFS, or a full cart workflow, those earn their price. If you just need to copy a card safely and verify it, the free options above will do the job.

How to make a free verified offload on Mac

1. Insert the card. With Copsy it's auto-detected by content; in DaVinci Resolve you open the Media page and the Clone Tool.
2. Choose destinations. Pick your external drive. In Copsy you can also add Google Drive or Dropbox to copy in the same offload; Resolve can write to more than one drive at once.
3. Copy with verification. Start the copy so the tool writes the files and generates checksums (ASC-MHL in Copsy, MD5 or SHA in Resolve).
4. Confirm the verify passed. Let the verification pass read the copy back and confirm every file matches. Only format the card after a clean verify.
