Frequently Asked Questions
1. Do I need to install anything to use GIF Monster?
No — all of our tools run directly in your browser. There’s nothing to install, and everything is free to use.
2. What video formats can I convert to GIF?
The Video → GIF tool supports MP4, MOV, AVI, WebM, FLV, WMV, and other common formats.
3. Are my files saved on your servers?
No. Files are processed temporarily to complete your request, then removed automatically. We don’t keep permanent copies.
4. Why is my GIF taking a long time to process?
Conversion time depends on your video’s length, frame rate, and resolution. Reducing the fps or output width will speed things up and shrink the file size.
5. How accurate is the QR → Link Decoder?
Our QR tool uses reliable open-source libraries and browser APIs. It will show you the decoded link, including redirects or tracking links, so you can see the real destination before clicking.
6. Can I validate HTML5 banners for ad networks?
Yes — our HTML5 Validator checks package size, file inventory, and external calls against common profiles like Google Display Network and DV360.
7. Can I use GIF Monster on mobile?
Yes! All tools are mobile-friendly. You can upload files, scan QR codes with your phone’s camera, and download results directly.
8. Are there limits on file size?
Uploads are capped at about 100 MB per file for performance reasons. Larger files may fail or take too long to process.
9. Is GIF Monster really free?
Yes. Every tool on GIF Monster is free to use. We may run ads to support hosting costs, but the tools themselves are open to everyone.
10. How often are new features added?
We update regularly based on what we need in our own workflows and what users request. Check the News & Updates section to see the latest improvements.
