Damask
What Damask is
Damask is a free, open-source digital asset manager that creative studios can run themselves through a web interface, API, or self-hosted deployment. It handles images, video, audio, PDFs, and documents. Projects, folders, tags, custom metadata fields, and cross-project collections organize files, while OCR full-text search and perceptual-hash visual search help locate them. Processing includes image thumbnails and transformations, video and audio transcoding, PDF thumbnails, OCR extraction, and background removal. Assets retain version history with rollback, and users can make resized, cropped, converted, or background-removed variants with previews and bulk workflows. Password-protected or expiring links support sharing, and public client comments work without an account. Damask accepts ingestion through IMAP, SFTP, WebDAV, S3-compatible storage, and email. It uses local storage by default, supports SFTP or S3 backends, and can run as Docker or a local single binary.
