PNG to GIF Converter

Yes. A PNG and a GIF both store a grid of pixels, so the conversion is a re-encode rather than a redraw: the browser decodes the PNG, then writes the same pixels into a GIF colour table. The only things that can be lost are colour depth, because a GIF table holds at most 256 entries, and alpha precision, because GIF transparency is a single on/off entry.

Yes, but only as fully transparent or fully opaque. GIF marks one palette entry as transparent and has no partial alpha, so a pixel at least half opaque in the PNG becomes solid and anything fainter becomes clear. A 400x300 logo converted here kept all 81,787 of its transparent pixels; its anti-aliased edge pixels were pushed to one side or the other.

Only if the PNG uses more than 256 colours. Below that, every colour keeps its own palette entry and the pixels come back byte for byte: an 802x602 screenshot with 222 colours still had exactly 222 after conversion. A photograph is different. One with 284,551 distinct colours was reduced to 256, which shows as banding across skies and other smooth areas.

Sometimes. Flat artwork with few colours usually shrinks: a 6.72 KB logo became a 3.32 KB GIF here. Photographs and gradients usually grow, because GIF's LZW compression cannot describe a row whose colour changes at every pixel, while PNG's filters can. A 1.7 KB gradient PNG came out as a 111 KB GIF. Check the New file size line before keeping the result.

Not here. This converter takes one file at a time and always writes a single-frame GIF, so selecting several PNGs converts only the first. An animation also needs a frame order, a delay for each frame and a loop count, none of which this page asks for. Use a dedicated GIF maker when you want movement rather than a change of format.

Not with this tool. An APNG carries several frames, but the converter draws the image onto a canvas, which yields one still frame, and the GIF it writes contains a single image block with no delay or loop information. You will get a static picture rather than the animation, so an APNG-to-GIF converter that understands frames is the right choice.

PNG stands for Portable Network Graphics, GIF for Graphics Interchange Format, and JPEG for the Joint Photographic Experts Group that defined it. PNG compresses without discarding pixels and stores 256 levels of transparency. GIF is limited to a 256-colour palette with one transparent entry, but can hold several frames. JPEG throws away detail to make photographs small and supports no transparency at all.

No. The file is read by the browser's file reader, drawn on a canvas and encoded to GIF by JavaScript running in the page, so the picture itself never travels over the network. The download link points at a blob held in your own tab's memory, and closing the tab discards it. Only the page and its scripts are loaded from the site.

Both accept GIF uploads, but a file converted here has one frame, so it behaves as a still image rather than an animation. If you wanted movement, this is the wrong tool. If a form, a bot or a theme simply refuses anything that is not a .gif, a single-frame GIF satisfies that requirement while looking exactly like the PNG did.

Yes: no charge, no account, and no watermark on the output. The conversion runs on your own machine, so there is nothing to meter; the practical limits are your browser's memory and your patience. A 400x300 logo took about 40 milliseconds here, a 640x480 photograph about 0.2 seconds, and a 4000x3000 PNG of 19 MB about 1.5 seconds to become a 5.26 MB GIF.

No. It describes RGB palette matching only. Partial transparency is always reduced to transparent or opaque, and excess colours are quantized.

No. This tool writes one GIF frame and one-bit transparency. Use PNG or WebP for smooth transparency and an animation editor for multiple frames.
