Frequently Asked Questions
What are the best dimensions for GIFs?
For web use, 640x360 or 854x480 pixels work well. For social media, Instagram uses 1080x1080 (square), Twitter supports up to 1280x720, and Discord recommends 640x360 or smaller.
Can I change GIF size without losing quality?
You can resize GIFs without significant quality loss using our Lanczos scaling algorithm. Making GIFs smaller generally maintains quality better than enlarging them.
What's the difference between resizing and compressing GIFs?
Resizing changes the dimensions (width x height) while compressing reduces file size. Both can affect quality, but they serve different purposes.
