You can upload your photos, illustrations, and vector art to Adobe Stock from the Adobe Stock Contributor portal, or directly through Lightroom Classic CC, or Bridge CC. For information on uploading video, please see Upload video to Adobe Stock.
Visit contributor.stock.adobe.com and sign in with your Adobe ID.
Select Upload in the header of the Contributor portal. Then, drag and drop the photos, illustrations, or vectors you want to submit. Alternatively, select Browse to locate your files, then select Choose.
In Lightroom Classic CC's Library mode, select the photos you want to upload to Adobe Stock and drag them into the Adobe Stock Publish Collection. Finalize your submission in the Contributor portal.
In Bridge CC, drag and drop your JPEG, EPS, or AI files to the Publish panel then finalize your submission in the Contributor portal.
If you get an error message when attempting to upload a vector file, your artboard is probably too small. Make sure your artboard is at least 15 megapixels.
