Blatt turns a sequence of photos into an animated GIF. You pick frames from your library, arrange them, set the speed and size, optionally apply a visual effect, watch a live preview loop, then export. Your source photos are never modified. This guide covers every part of the app.
The filmstrip shows every frame in order. The frame at the left plays first.
Frame Rate
Sets how many frames play per second, from 1 to 30 fps. Lower rates give a slideshow-like feel; higher rates produce smooth motion.
Loop
Toggle looping on for a GIF that repeats forever, or off for one that plays through a single time and stops.
Four output size presets keep file sizes under control:
Tap a filter to apply it to every frame before export. Adjustable effects show an intensity slider; fixed-look effects apply with one tap. Tap None to remove the effect.
Chrome, Fade, Instant, Mono, and Process — classic photo-style colour treatments that apply with a single tap.
Thermal and X-Ray remap the image into bold false-colour looks. Both apply with one tap.
Droste (a recursive spiral), Glass (a textured refraction), and Zoom Blur (a radial motion blur) — each with an adjustable intensity.
Crystallize, Pixellate, and Dots break the image into adjustable cells, blocks, or halftone dots.
Otsu reduces each frame to high-contrast black and white using automatic thresholding. Applies with one tap.
The preview area plays your animation at the chosen frame rate with the selected effect applied — exactly as it will export. Tap to pause and tap again to resume, so you can study a single frame before you commit.
Export opens the share sheet, so you can save the GIF to Photos or Files, send it in Messages, or hand it to any other app. Every animation you export is also saved to Blatt's own gallery, so you can come back and re-export it any time.
After an export, an Undo action moves the exported file to the Trash instantly. Your original source photos are never modified — Blatt only ever reads them.
Does Blatt modify my original photos?
No. Blatt only reads your photos to build the animation. Your library is never changed, and the GIF is saved as a brand-new file.
How many frames can I use?
As many as you like. Keep in mind that more frames and higher resolutions make a larger GIF — use the size presets to keep the file manageable.
Why is my GIF file so large?
GIF file size grows with the number of frames, the output resolution, and the amount of colour and motion. Choose a smaller size preset (Square or Small) or use fewer frames to shrink it.
Can I add music or sound?
No — GIFs are silent by format. Blatt makes looping animations from your photos, without audio.
My frames look out of order
Frames play left to right along the filmstrip. Drag any frame to a new spot to fix the order, then check the preview.
The animation plays too fast or too slow
Adjust the frame rate. Higher fps speeds the loop up; lower fps slows it down.
An effect looks too strong
If the effect has an intensity slider, lower it. For fixed-look effects, tap None to remove it or choose a gentler one.
