GIF vs WebP
WebP combines lossy or lossless 8-bit image coding with alpha and animation. It is a web delivery option when those features matter; high-precision samples and editable source structures need another working format.
Image format
Indexed-colour images and simple frame animation. GIF uses LZW compression and palette-index transparency.

Graphics Interchange Format
CompuServe created GIF for exchanging raster graphics across systems. Images refer to colour-table entries instead of storing full RGB values at every pixel. A table contains at most 256 colours; individual frames can have different tables. This suits diagrams and small animations more readily than continuous-tone photographs.
LZW stores the indexed data losslessly. Converting full-colour artwork to that palette can still lose information or add dithering. GIF89a adds control blocks for frame delay, disposal and a transparent palette index. Transparency is binary: GIF cannot express a partly transparent edge with an alpha channel.
Use GIF for simple animated illustrations or legacy workflows that expect GIF. Inspect disposal and timing when processing multiple frames. A still export can retain one rendered frame but cannot reproduce movement, and modern alpha-capable formats are more suitable for smooth translucent artwork.
LZW compression is lossless for the stored palette indices. Colour reduction before encoding is not lossless for an arbitrary RGB source.
GIF’s version names and Compuserve’s programming reference document the move from image interchange to controlled image sequences.
Different formats, different trade-offs. Choose for the image and the workflow.

PNG preserves decoded pixels losslessly and can carry alpha. It is useful for transparent graphics and screenshots; it does not preserve editable document layers or camera sensor data, and photographic files can be large.
AVIF uses AV1 coding and supports alpha, image sequences and higher bit depths for HDR workflows. It is worth evaluating for final delivery; codec settings and the receiving application determine whether its additional features survive.
JPEG makes a compact photographic delivery file, but ordinary JPEG discards detail and has no alpha. Keep the richer source for editing and use JPEG when the receiving workflow expects an opaque photo.

A GIF pixel is either transparent or one palette colour. There is no fractional alpha for blending an edge with an unknown background; choose an alpha-capable format for that requirement.
Check animation playback, loop extensions and frame disposal. A viewer that displays the first frame is not necessarily processing the complete animation.
A still target requires selecting and compositing a frame. Animated targets need timing and disposal preserved. Converting to RGB cannot recover colours lost during palette reduction.
