About

What D4 Loot Filter Viewer is and why it exists.

What this tool does

D4 Loot Filter Viewer ("https://www.d4lootfilter.com") is a free tool that decodes Diablo 4 loot filter import codes and displays them in a readable format. Loot filter codes are base64-encoded binary data (protobuf) that Diablo 4 uses to represent a filter's rules, colors, and conditions. Paste a code into the decoder and this site parses that binary data and shows you exactly what the filter does: rule by rule, condition by condition.

This exists because Diablo 4's loot filter import/export feature is PC-only. Players on PS5 and Xbox can build filters through the in-game menu, but they cannot paste an import code directly into the game the way PC players can. If a console player wants to use a filter someone else built, they have no built-in way to see what that code actually contains. This site fills that gap: it decodes the code so a console player can read the rules and manually rebuild them, one entry at a time, in the console's own filter menu.

Why it was built

Loot filter codes are shared constantly by build guides and the community — Maxroll, Mobalytics, YouTube guides, and Reddit threads all post codes alongside builds so other players can copy a filter someone has already fine-tuned. That workflow works fine on PC, where the code is pasted straight into the game. On console it breaks down completely, because there was no way to see inside the code without a PC client. This tool was built to close that gap for console players, so a shared filter code is no longer useless just because you're playing on a PS5 or Xbox.

How it works

The decoding happens entirely server-side: a code is submitted, parsed, and the result is returned as structured data. Nothing you paste in is stored or logged beyond the life of that single request. The decoded output shows each rule's name, its visibility setting (Show, Hide, Recolor, and related states), its color if one is set, and its conditions — item type, required or optional affixes, rarity, greater affix thresholds, and other criteria the filter checks against. The goal is to make the rule as easy to read on screen as it would be in the in-game filter editor, so it can be typed back in by hand on console.
