Before launching a campaign, many media buyers remove watermarks and alter file hashes — but metadata often goes untouched. EXIF blocks can carry the device model, GPS coordinates, creation timestamps and other embedded data that may signal the file's origin or attract questions from platform moderation.
What EXIF is and why it matters for ad creatives
EXIF is a block of service data written automatically into a file by a camera or editor. It can include geolocation, device model, timestamps and capture settings. Video files store equivalent data inside the container.
For ad materials this creates two problems. Some advertising platforms read metadata during file review. And if the creative was adapted from third-party material, original tags stay inside and can point back to the source.
Removing EXIF does not touch the image or video itself — pixels stay the same, quality does not drop.
What Contentor EXIF Editor does
Contentor EXIF Editor is a free, browser-based tool that requires no installation. It covers four functions: viewing all metadata recorded in a file before processing; editing individual fields rather than deleting everything; full removal of EXIF and other service data; and batch processing of up to 30 files at a time. Both images and video are supported. Processed files are downloaded after the job runs.
In practice: upload a batch, review what each file contains, choose what to delete or edit, download the clean files. Batch processing up to 30 files is useful when preparing several dozen banners or video clips before a push — handling each one manually in a desktop editor at that volume takes considerably longer.
Being browser-based means nothing needs to be installed locally. That is practical when working across different machines or in teams where access to a single workstation is limited.
Limitations to keep in mind
Thirty files per session is the ceiling for batch uploads. Larger sets require multiple runs.
Because this is an online service, files are uploaded to a third-party server. That is worth considering when working with sensitive material.
The tool modifies only metadata, not the file's content. Altering the file hash requires separate steps.
