GIF to PNG Converter

Graphics Interchange Format (GIF) is a mixed image format used for short silent loops, simple animations and legacy compatibility. Files saved as GIF usually come from CompuServe. Before converting, check that the source is the highest-quality copy you have, because every later step can only preserve what is already there.

The target is Portable Network Graphics (PNG), a lossless image format chosen for screenshots. The target is lossless, but it cannot restore detail the lossy source already removed; expect a much larger file with the same visible quality. The output keeps the original dimensions or sample rate unless you change them, so this step changes the encoding rather than the content.

PNG is lossless with full alpha support. The encoder here writes a standard RGBA image, so screenshots and logos stay pixel-exact at the cost of size. Animated frames are not preserved by {toExt}: only the first frame is written, and the motion sequence is lost. GIF’s 256-colour palette is expanded to full RGB, so gradients stop banding but the file may grow before the new encoder compresses it again. Expect a larger output file: the format trades size for lossless fidelity.

This conversion runs locally in your browser tab through Canvas or FFmpeg.wasm. The file is read from your device, decoded, re-encoded and handed back as a download; it is not uploaded to a conversion server. That keeps private recordings, client material and unreleased artwork off shared infrastructure.

After the download, play or open the result before deleting the original. Check the first and last seconds, confirm that transparency, rotation metadata or sample rate survived, and compare file sizes. If something looks wrong, retry with a higher quality setting rather than converting the output again.
