Frequently Asked Questions

What is Slink?

Slink is a self-hosted image sharing platform built with Symfony and SvelteKit that gives you complete control over your images and share links. It's positioned as a private alternative to public image hosts like Imgur: upload images to your own instance and share them with a link — without relying on third-party services.

Are my shares private by default?

Yes. All shares are private by default and only accessible to whoever holds the link. You can optionally require a password to view a share, set an expiration so a link auto-revokes after a chosen time, shorten URLs for easier sharing, or group images into a collection shared via a single link.

Can I self-host Slink?

Yes. Slink is distributed as a single container that bundles the web server, database, and image processing, which makes deployment dramatically simpler. Storage can be local filesystem, SMB, or Amazon S3 (and S3-compatible). It supports email/password login plus SSO/OIDC providers such as Google, Authentik, Keycloak, Authelia, and Pocket ID.

What image formats and upload features does it support?

Slink supports PNG, JPG, WEBP, SVG, BMP, ICO, GIF, AVIF, HEIC, and TIFF, with parallel multi-file uploads, progress tracking, image compression, and deduplication that detects duplicate images at upload time. It integrates with ShareX for automatic screenshot uploads and offers a public API with personal API keys for automation.

Is Slink open source?

Yes, Slink is open source under the AGPL-3.0 license and available on GitHub. There is no paywall or required cloud service — you can run it entirely on your own infrastructure. It also includes an admin dashboard with user/storage management, image moderation, nested tags, bookmarks, comments, and notifications for community use.

What is Slink best used for?

Slink is a great fit for private image sharing among friends, family, or a team; hosting screenshots for GitHub issues, portfolios, or blogs; or as a self-hosted replacement for public image hosts. Its community features (explore, bookmarks, comments) also make it suitable for small image-sharing communities.
