Many placements
Several placements need different sizes. File requirements are not the same on every unit. Landing URLs arrive separately, one asset is still missing while the rest look finished, and a corrected version shows up in a different channel. Launch readiness is hard to read when the pieces are scattered.
One request
Back to School Campaign
Four placements, each with its own requirement, in the same creative request.
Placement specs
Each placement becomes a slot. You can require exact dimensions or an aspect ratio, accepted formats, a max file size, a landing URL, and publisher instructions. The person uploading sees that requirement with the slot.
Keep the offer in the right third of the banner.
Leave clear space above the product for the headline.

Upload to the matching slot
Replace or remove a file, and add a note if the submission needs context.
One link
Advertisers and partners open one public link and see every requested asset. They upload to the correct slot without a DropAsset account. If a file needs to change, they can replace or remove it and leave a note on the submission.
Before launch
DropAsset checks the upload against that slot: exact dimensions, aspect ratio, file format, file size, and a landing URL when you require one. When a change is compatible, it can downscale, compress, or convert the file and keep the Original beside a Ready version.
DropAsset does not crop, stretch or upscale a creative just to make it pass.
Exact dimensions
Compared when the slot asks for a pixel size
Aspect ratio
Compared when the slot asks for a ratio
File format
JPG, PNG, and WebP against that slot
File size
Flagged when the file is over the limit
Landing URL
Collected when that placement requires one
Readiness
The request shows Ready, Needs attention, and Awaiting upload for each placement. That is asset readiness for the campaign, not a task list. There are no assignees, due dates, or comment threads.

Destinations
A landing URL can be required on the asset slot. Different placements can point to different destinations, and the file stays in the same intake as its URL. DropAsset does not check link health or redirects.

DropAsset
Yes. One request can include multiple asset slots, so a homepage banner, a mobile unit, a newsletter placement, and a social creative can be collected together.
No. Advertisers and partners open the public upload link and submit files without a DropAsset account.
Yes. Each asset slot can have its own dimensions or aspect ratio, accepted formats, file-size limit, landing URL requirement, and publisher instructions.
Yes. Each slot shows Ready, Needs attention, or Awaiting upload, so you can see which placements are complete and which still need a file or a correction.
Yes. A landing URL can be required on each asset slot, so different placements can carry different destinations. DropAsset stores the URL with that submission. It does not check whether the page is live or follow redirects.
No. DropAsset focuses on creative intake, validation and asset readiness. It does not currently provide project timelines, task assignments, approvals or campaign performance reporting.
Create one structured request for your campaign placements and give contributors a clearer way to submit the assets you need.
