Vertical footage is everywhere now
Almost everything shot on a phone is vertical: 9:16 clips headed for Reels, Shorts, TikTok, or Stories, screen recordings of a phone app, a quick video a friend sent in a chat. Turning one into a GIF is great for a reaction, a product moment, or an embed that autoplays without sound. The only real decision is what shape you want the GIF to be, and that is where the crop tool earns its keep.
What the GIF handles all of this in your browser tab, locally. Vertical MP4 and MOV from a phone decode cleanly in any modern browser, so the clip loads straight into a preview with no signup and no upload. If the clip came off an iPhone specifically, the iPhone video to GIF page has notes on getting it off the phone first.
Keep it tall or crop to a shape
The crop is locked to real ratios, so nothing ever stretches. Your main choices for vertical footage:
- 9:16 keeps the whole vertical frame, ideal when the action fills the tall shape and you want it to look like the original.
- 4:5 is a gentler portrait crop that trims a little top and bottom, a nice fit for feeds that prefer a shorter portrait.
- 1:1 crops to a clean square, which travels well in chat, on a timeline, or as an avatar loop, and keeps the file smaller than a tall frame.
Drag the crop box to frame the subject before you commit. A tall 9:16 GIF carries more pixels and therefore more weight, so if size matters, a square or 4:5 crop is the quieter, lighter choice.
Trim to the beat that matters
Vertical clips are often longer than the moment you actually want to loop. Drag the timeline handles to cut to two to five seconds, and nudge single frames with the arrow keys so the loop starts and ends clean. For a reaction or a punchline, the exact in and out frames are the whole thing, a frame early or late and the timing dies.
Trimming tight is also the first and biggest step toward a small file, before you touch any other setting.
Size settings for a light vertical GIF
Tall GIFs can get heavy because they are, well, tall. Keep it in check:
- Scale down the dimensions. A vertical GIF around 360 to 480 pixels wide is plenty for chat or an embed and much lighter than full phone resolution.
- Frame rate around 10 to 15 fps handles most phone footage, and lower fps means a smaller file.
- Colors and dithering: pull the palette to 64 to 128 colors to shrink the file, with a little dithering so gradients stay smooth.
A live estimated size updates as you adjust, so you can watch it fall. Aim under roughly 2 MB for chat, and if you want it really small, the small-file GIF guide shows which knob to turn first.
Local, private, and free
The whole conversion runs in your browser on your device, so your footage never uploads and never lands on a server. When the preview looks right and the size is where you want it, hit convert and the GIF downloads straight to you, clean, with no watermark and no server-imposed cap. Post it, embed it, or drop it in a chat, it is yours.
