Threads Image Resizer

Resize for the current native 3:4 look, square, 4:5, landscape, link cards and profile images. Keep one focal point, optimize to Threads’ common 8 MB ceiling, preview the post in-feed, and create a unique multi-panel panorama seam pack for swipe/pinch-style visual sequences.

Native 3:4 firstUses a 1440×1920 portrait preset while keeping 4:5 and square fallbacks for cross-tool compatibility.

No fake crop rulesThreads often preserves mixed image dimensions, so the tool avoids pretending every post is forced into one crop.

Panorama seam packSplit one source into 2–4 adjacent 3:4 or square panels and export them in posting order.

Free batch exportMulti-size ZIP, local processing, no signup, watermark or premium resize gate.
