Agencies and people teams often refresh dozens of headshots at once. Normalize every crop to the same square frame, compress so uploads stay snappy, then ZIP before you hand files to each profile owner.
Follow the LinkedIn profile workflow (upload → resize → compress → checks → ZIP), then upload in LinkedIn's profile or company page editor.
In Bulk Resize, pick LinkedIn Profile Photo (800×800). More context: LinkedIn image resizer.
Then run Bulk Compress. If uploads fail, see listing images too large to upload and batch vs one-file compressors.
