Frequently Asked Questions

Does converting to GIF reduce image quality?+
GIF is limited to 256 colors per frame, so photographs may lose color detail. For graphics, logos, and simple illustrations, GIF produces excellent results. For photographic content, consider WebP or AVIF for better quality.
Is it safe to convert images here?+
Yes. By default, conversion runs entirely in your browser via WebAssembly — your files stay on your device. If your browser doesn't support local processing, images are processed on our secure servers and deleted automatically within 72 hours of completion.
What is the maximum file size I can convert?+
Browser-based processing handles images up to approximately 100 MB depending on your device's CPU and RAM. For very large files, the tool automatically routes processing to secure cloud servers.
How do I create an animated GIF?+
Upload multiple images — they become frames in your animation. Set the frame rate, looping behavior, and color palette, then click Create GIF. You can reorder frames by dragging them.
Why is GIF limited to 256 colors?+
The GIF format uses an indexed color palette with a maximum of 256 entries per frame. This makes GIFs compact but less suitable for photographic content. Use dithering to simulate more colors and reduce banding.
Does GIF support transparency?+
GIF supports single-color transparency — one specific color is designated as fully transparent. Unlike PNG or WebP, GIF does not support partial (alpha-channel) transparency.
Can I control how the GIF loops?+
Yes. You can set the animation to loop forever (continuous playback) or play once and stop. This setting is embedded in the GIF file and respected by all browsers.
Are my images uploaded to your servers?+
FastImageTools processes images locally in your browser whenever possible. In rare cases where local processing isn't supported or fails, we automatically process images on our servers to complete the job. Server-processed files are deleted within 72 hours of completion. This happens transparently — no action is required from you.
