How to deliver high-resolution files to clients without losing control of the download
Client file delivery goes wrong when the preview is already the product. High resolution file sharing should be a second state: they have seen enough to approve, and only then do the masters move.
To deliver high resolution files to clients is a control problem, not an upload-size problem. The files will fit. The mistake is sending the print-ready set as the first look, or leaving a drive on "anyone with the link" after the job ends. Creative file delivery should have a preview state and a release state.
Photographers, designers, and filmmakers already know the difference in the studio. The client sees a proof. The lab gets the TIFF. 2026 just moved that ritual onto phones. If the first link is already 100MB per still, you lost the download before anyone said yes.
Preview quality is a decision
A preview has one job: let them approve. It should be sharp enough to judge focus, type, and grade. It should be weak enough that it cannot replace the delivery. Watermarks help when the set is easy to steal. Softness or a smaller long edge helps when a mark would hide the work. Password the door when the people are named.
- Stills: review size plus a mark, or a blur on faces if the set is sensitive.
- Motion: a watermarked review codec. Keep the mezzanine off the preview link.
- Design: flattened pages. Outlines and working files wait for release.
Approval, then the masters
Send the preview on a door you control
Password it. Say how long it stays up. Password a share if the set should not travel. Do not drop masters into the same thread "so they can see it properly."
Collect a clear yes
A reply, a signed PDF, a checkout if money is still due. Client approval is the switch. Until then, high resolution file sharing is optional and usually a mistake.
Release the finals on a link you can shut
Same folder if the tool can swap the unpaid view for the paid or approved view. Separate folder if you must. Either way, secure client downloads should be a URL you can expire, not an attachment that lives in their mail forever under your name.
Expiry and passwords are part of delivery
Professional file delivery includes an end date. Agencies change staff. Couples share with a printer, then a cousin, then a Facebook group. A password you can rotate is kinder than a public folder you forgot. When the job is done, turn the share off. The library still has the pack if they come back under contract.
Spike keeps preview rules and the masters in one folder so you are not maintaining two archives. A drive can do a clumsy version of this with two folders and a calendar reminder. The habit is the same: the first look is not the release.
After they download
Leave the release up long enough for hotel wifi and a second art director. Then shut it if the contract is time-boxed. If a file was wrong, replace it in place and tell them the URL did not change. That is client file delivery as a place, not as a series of emergency transfers.
If they can print it, you already delivered. Make sure you meant to.
Watermark and blur choices for stills live in the photo preview note. This page is the sequence: look, approve, then hand over the high-resolution set on purpose.
Questions
Good to know
Small enough that a screenshot is not a print or a broadcast master. For stills, a long edge that looks fine on a phone and fails on a wall. For video, a watermarked H.264, not the ProRes. For design, a flattened PDF, not the outlined pack.
