Seasonal favicon variations.

Tone your existing favicon in the season's color: red or green for the holidays, orange for Halloween, pink for Valentine's. The shape stays recognizable; the mood changes.

Warm reds, forest green or a festive gold; one tone each for the days you run a campaign.

Sunset for orange, or violet for a spookier version.

Spring: forest and pastel tones. Summer: sunset and ocean. Autumn: warm oranges, sepia browns, muted golds.

Only the ones with a campaign behind them. Too many swaps confuse returning visitors.

Upload the seasonal ICOs and switch the <link rel="icon"> when the season starts, by hand or from your CMS or deploy.

Each pixel is read as hue, saturation and lightness; the tone's hue and saturation replace the pixel's and its lightness stays. Shading and highlights stay, so the icon keeps its shape and only its color changes.

Pick a preset (Sepia, Ocean, Violet, Teal, Sunset, Forest, Rose, Slate) or type any hex. The same hex gives the same result on every icon, which is how a set stays consistent.

The largest frame of the ICO is toned and the result is a PNG. Modern browsers take a PNG favicon as it is; for a favicon.ico or a Windows icon, pack it with the PNG to ICO tool.

No. The ICO is read and its frames decoded by JavaScript on your device; the page makes no request with your file. Load it, go offline and it still works.

No. The "Seasonal favicon variations" tool is free and opens without a sign-in, an account or an install.

Nothing. The "Seasonal favicon variations" tool holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
