Before you convert
- Keep a backup of your original file before converting so you can roll back if needed.
- Decide on a background color for transparent areas—WebM fills them with solid color during conversion.
- Review known pain points: Inefficient for high-resolution or long animations compared to video formats. Adjust your source file accordingly.
- Note the target resolution and frame rate to avoid unexpected stretching or stutter.
Quality tips
- Use the resize controls to match the pixel dimensions your project actually needs.
- Preview the background fill—set it to white, black, or brand colors so transparent elements look intentional.
- Start with a high-quality setting (85–90%) and only reduce it if file size targets demand it.
- Trim clips and set the frame rate before converting to avoid double-encoding footage you do not need.
- Download the result immediately and open it in the target application to verify everything matches expectations.
Where WebM fits best

Frequently asked questions
Does converting GIF to WebM reduce quality?
Yes, WebM uses lossy compression. Start with the highest quality setting available and compare the converted file against your original. If you need a perfect copy, keep the GIF source as an archive.
What happens to transparent pixels when I move from GIF to WebM?
Because WebM does not store transparency, the converter applies a solid background. Choose the background color that matches your design system or add a new layer in an editor before uploading.
How can I keep WebM file sizes reasonable?
Trim the clip, export with a constant or target variable bitrate, and align the frame rate with your footage. Dropping unused audio tracks also saves space.
