Photo sequences without timeline software
Order is the edit
Create GIF from images by dropping a chronological set, then dragging frames when the beat is wrong. Two-frame before/after pairs, comic panels, and a day’s travel stills are the same tool with different delay. Mixed aspect ratios will jump — crop or letterbox to one box before you encode. Live Photo packages are not a source; export stills first.
Slideshow pacing versus animation density
A readable slideshow often wants 400–800ms on text-heavy frames and less on establishing shots. Stop-motion stills want tighter delay. Gif Studio is not After Effects: you get about 30 frames and a ~1200px ceiling, plus reverse, boomerang, or pingpong if a hard cut feels abrupt. Infinite loops suit chats; counted loops suit decks that should rest on the last beat.
Which stills drop in natively
JPG, PNG, and WebP go straight on the timeline. iPhone HEIC, BMP archives, TIFF scans, AVIF stills, and DDS textures need a convert-first raster, then come back. Normalize a mixed folder to PNG or JPG if the picker is picky. Nothing uploads to a Convertify4u server on this encode.
