TierDeck is a tier list maker with no ads, no account required. Rank anything you love and export a tier list image sharp enough to post anywhere. It opens fast and works offline. RANK ANYTHING • Start from S to F, 1 to 5, Tier 1 to 3, or Yes / Maybe / No. You can also write your own labels • Drag items between tiers, and reorder them inside a row • Add, insert, move, recolor, and delete tiers as you go • Undo and redo every change • Unlimited lists, always ADD IMAGES FROM ANYWHERE • Share photos, screenshots, posts and links to TierDeck from almost any app, and they land right in the unranked pool • Paste a link to a post or a video and TierDeck finds the picture in it • Pick several photos at once from your library, or paste an image from the clipboard MADE TO LOOK RIGHT • Tile shapes: square, poster, cover, wide, or each image's own proportions • Fill or fit, and drag any image inside its tile to frame it exactly • 1 to 8 columns, three row heights, item names on or off • Four colorblind-safe palettes, plus any hex color you like • Light and dark modes, and a board background you choose • A roomy layout on iPad and tablets EXPORTS THAT DON'T LOOK COMPRESSED • Your images are never recompressed when you add them. Compression is an export-time decision that only happens once • PNG or JPEG, with a quality slider • Original, 4K, and 8K resolution. 8K draws the whole board up to 8400 px wide • Transparent background for PNG, for when the board goes into a thumbnail or a stream overlay • Save straight to Photos, or send it to the share sheet SHARE THE TIER LIST, NOT JUST THE PICTURE • Export a .tiers file. Your tiers, placements and images are rebuilt exactly on someone else's device • Or export a tier list template: the same items with nothing ranked, so a friend can make their own ranking • Opening a .tiers file someone sent you is always free PRIVATE BY DEFAULT • No account, no sign-in, no analytics, no tracking, no ads • Your lists and images stay on your device because there is no server to send them to • Everything except adding an image from a link works with no connection at all FREE, OR UNLOCK PRO Free: unlimited lists, up to 30 images per list, Original-resolution exports with a small TierDeck mark, the built-in palettes, and .tiers import. Unlock Pro: unlimited images per list, no watermark, 4K and 8K exports, transparent backgrounds, any hex color, and .tiers export.
