Format guide
What is GIF?
Graphics Interchange Format is a palette-based image format famous for short looping animations and simple graphics, created by CompuServe (1987). GIF shines for stickers, reactions, and low-color animations. It only supports 256 colors and 1-bit transparency, so photos look banded — use video (MP4/WebM) or PNG/WebP when you need quality or full alpha.

GIF compression & quality
GIF compression: varies. Lossless (or non-destructive packaging) keeps reconstructable data — size savings come from packing efficiency, not throwing detail away. Typical size profile: Small for simple loops; balloon with long/hi-res clips. Quality note: Limited to 256 colors; fine for flat graphics, poor for photos
Quality: Limited to 256 colors; fine for flat graphics, poor for photos
Typical size: Small for simple loops; balloon with long/hi-res clips
Transparency & animation
GIF supports binary (on/off) transparency only — not smooth alpha gradients.
GIF is widely used for short loops; longer or higher-quality motion is usually better as MP4/WebM.
GIF metadata
Commonly supports EXIF, IPTC, and/or XMP depending on encoder (camera make, GPS, orientation, color profile). Strip metadata before public sharing if privacy matters.

GIF FAQ
What is a GIF file?
GIF is a palette-based image format famous for short looping animations and simple graphics. GIF shines for stickers, reactions, and low-color animations. It only supports 256 colors and 1-bit transparency, so photos look banded — use video (MP4/WebM) or PNG/WebP when you need quality or full alpha.
Is GIF lossy or lossless?
GIF is typically lossless or non-destructive in common use (varies).
Does GIF support transparency?
GIF supports binary (on/off) transparency only — not smooth alpha gradients.
How do I open a GIF file?
Any browser or image viewer plays GIF. For frame inspection, use an editor that exposes the timeline.
How do I convert GIF privately?
Convert GIF to MP4/WebM for smaller smoother video, or to PNG for a still frame — Format Convertly runs the conversion in your browser. Format Convertly keeps processing in your browser so files are not uploaded to a conversion server.
Should I use GIF or MP4 for short clips?
GIF is culturally expected in chat; MP4/WebM is usually smaller and smoother for the same motion on websites.
Are my GIF files uploaded on Format Convertly?
No. GIF conversion runs in your browser. Files are not sent to Format Convertly servers for processing.
