Web tool help

Supported browsers

Use the latest version of Safari, Chrome, Edge or Firefox. Keep the tab open while Rebuild works, especially with large files or multiple downloads.

A PDF won’t open

• Check that the file opens in a normal PDF viewer.
• If the PDF is password-protected, unlock it with the correct password first.
• Download cloud-only files to the device before selecting them.
• Try a desktop browser if the document is unusually large.

The browser ran out of memory

Document processing can temporarily use several times the file size in memory. Close other large tabs, work with fewer files, or move to a computer with more memory.

A download didn’t appear

Check the browser’s download list and site permissions. On mobile, you may be asked where to save each file. If a tool creates several results, allow each download when prompted.

Check the result

Open the downloaded file in another viewer and check every page before deleting the original. After compression, inspect small text, images, links, forms and searchable text.
