PNG to GIF Converter

A PNG to GIF converter rewrites a still PNG image as a GIF file with the same width, the same height and, on most artwork, the same visible picture. The image is not resized, cropped or moved. What changes is the container and the colour budget, and the colour budget is the part worth understanding before you convert.

Most people arrive here because something on the other end will only take a .gif. An old forum avatar field, a legacy CMS uploader, an ad slot spec, a bot or game that loads sprites by extension: the artwork is finished, it is a PNG, and the box refuses it. The conversion itself is a formality. It is also lossy, which is the bit nobody mentions.

GIF stores at most 256 colours per frame. PNG stores millions, plus an 8-bit alpha channel. Converting quantises the image down to a 256-entry palette, and flat artwork comes through that step untouched: screenshots of text, line drawings, pixel art, logos and UI mockups rarely use more than a couple of hundred colours to begin with. Photographs and soft gradients do not survive as cleanly, because a smooth transition has nowhere to go but into visible steps, an effect called banding. Transparency narrows in the same way. GIF alpha is one bit per pixel, so a pixel is either fully transparent or fully opaque, and the soft anti-aliased edge around a PNG logo hardens into a jagged outline against whatever sits behind it.

One thing this page does not do: it does not build an animation out of several PNG files. One PNG in, one GIF out, one frame, every time. Animated PNG files are read as stills and come back as a single frame too. If you have a numbered sequence of frames waiting to become a moving GIF, this is the wrong page.

Here is a run in full. Drop a 1200x800 screenshot called dashboard.png onto the page and it converts straight away. Its row shows the input size, an arrow, the output size and the percentage change, with the line "GIF has 256 colours, so smooth gradients may band." beneath it, and clicking the thumbnail opens the GIF large with its 1200x800 dimensions. The download icon on the row saves dashboard.gif. Add nine more screenshots and the Download All (10 images) button in the list header writes converted-gif.zip with all ten files inside, numbering any duplicate names rather than overwriting them.

Everything runs client-side. Your browser reads the file, decodes it, draws it onto a canvas and encodes the GIF there, so no copy of the image is sent anywhere and the page keeps working with the network disconnected once it has loaded. Two things follow from that canvas step. Any metadata or colour profile attached to the source is dropped, and an image above 100 megapixels is refused with a message instead of freezing the tab. There is no limit on how many bytes a file may be, and the tool is free, no signup, with a daily cap on conversions.

• The PNG is decoded and the GIF is encoded client-side, inside this browser tab, using the Canvas API and a small GIF encoder that ships with the page. No image is uploaded.
• The daily usage check reports how many files were converted, their combined size in bytes and the target format. File names and pixels are never sent.
• Text chunks, colour profiles and any other metadata in the PNG are left behind, because the GIF is built from the decoded pixels alone.
• Converted GIFs stay in the tab's memory until you remove them, press Clear All or close the page. Nothing is kept on a server.
• If the usage check cannot reach the server, the conversion still runs, so the page keeps working offline once it has loaded.
