When a GIF needs to become a JPG
GIF is a 1987 format that survives because of animation, but as a still-image container it shows its age: a 256-color palette, large file sizes for photographic content, and upload forms that frequently want JPG or PNG only. Old clip art, forum images, and single-frame GIFs exported by legacy software all travel better as JPG — the format every printer, editor, and website accepts without complaint.
How the conversion handles your GIF
Your browser decodes the GIF natively inside a Web Worker, redraws it at its original dimensions, and re-encodes it as a high-quality JPEG (92%). If the GIF is animated, the first frame is used — JPG is a still format, so a one-frame snapshot is the honest result. Transparent regions are flattened onto white, because JPG has no alpha channel; if you need the transparency kept, use the GIF to PNG converter instead.
Nothing is uploaded at any point. You can queue a whole folder of GIFs, watch each one report its new size, and download everything as a single ZIP.
What to expect from the output
For photographic GIFs, JPG almost always comes out smaller and smoother, because JPG stores full 24-bit color instead of a 256-color palette. For flat graphics with hard edges — logos, pixel art, screenshots of text — PNG preserves those edges better; JPG can introduce faint ringing around sharp lines. Pick the output that matches the content, not the habit.
