GIF exists for one modern reason: short looping animation without an audio track, embeddable in older email clients and messaging platforms. Static GIFs are almost never the right choice — PNG (lossless) or JPG (compressed) is always better. Animated GIFs are limited to 256 colours and grow quickly; MP4 or WebP is typically better for anything over 2-3 seconds.
PNG supports millions of colors (24-bit + alpha) while GIF is limited to 256 colors per frame with 1-bit transparency. The conversion quantizes the PNG's full color space down to 256 colors using median-cut or octree algorithms, maps transparent pixels to GIF's binary transparency (fully transparent or fully opaque — no semi-transparency), and applies LZW compression. Photographs lose visible quality; simple graphics with few colors convert cleanly.
Convert PNG to GIF for simple graphics, logos, or icons that need to display in contexts requiring GIF format. For static images, PNG is almost always better — GIF's only advantage is its universal support for simple animations. This conversion is rarely the right choice for photographic content.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It uses DEFLATE lossless compression, meaning every pixel is preserved exactly as intended — no visual information is discarded during encoding. PNG was developed by the web community and standardized by the W3C and ISO, making it one of the most trusted and universally supported image formats available.
PNG is best suited for screenshots, graphics, logos, and any image that requires transparency. Its support for a full alpha channel allows smooth, semi-transparent edges that blend seamlessly with any background. The main trade-off is file size — PNG files are significantly larger than JPEG for photographic content because no visual data is discarded. PNG does not natively support animation; for animated sequences, APNG (Animated Portable Network Graphics) serves as its extension.

WebP is already smaller than JPG and PNG, but you can compress it further. Here are the optimal quality settings and when to use lossy vs lossless WebP.
Not every image format works in every email client. JPG is the safest bet for photos, PNG for screenshots. Here is when to use each and what to avoid.
PNG files are notoriously large. Here is how to get them under 50KB for web use without making them look terrible, plus when to ditch PNG entirely.
When you need to convert 50 or 500 images from HEIC to JPG, PNG to WebP, or any other format, doing them one at a time is not an option. Here are the best batch conversion methods compared.
