Details that travel quietly
Author names, document properties, camera details, dates, and selected image metadata can carry context further than intended.

WHAT THE CHECK CAN CATCH
Visible doesn’t always mean ready to share.
CheckBefore turns common file surprises into a short, human decision list—what you can remove now, what needs your attention, and what remains unchanged.
Content beyond the page
Comments, hidden sheets, rows, columns, and revision traces can survive after a document looks finished.
Hidden worksheetReview requiredLeft unchanged for your decision
Decisions that stay visible
When automatic removal could change meaning or behavior, we keep the item clear and ask you to review it.

The standard check happens where the file already is: your browser.
We do not need the original file, its visible content, or its filename for standard scanning. The original remains unchanged; cleaning creates a separate copy.

CLEAR BEFORE YOU BEGIN
Questions worth answering upfront.
Does CheckBefore guarantee a file is safe?
No. Results reflect only the checks performed. Review visible content and every item marked for a manual check.
Will cleaning change my original?
No. CheckBefore creates a separate copy. You can restore and rescan the original in the current session.
Are all hidden items deleted?
No. Supported cleanup is explicit. For example, Excel hidden items are made visible rather than deleting cell contents.
Which formats are available?
.xlsx, .docx, .pdf, .jpg, .jpeg, .png and .webp. Older Office formats and HEIC are not currently supported.
