Frequently Asked Questions
What is the YouTube banner file size limit?
There is an upload size limit for channel banners. If you see an error, compress more or switch formats. Always trust the upload UI message if it differs.
PNG or JPG for YouTube banners?
Use PNG for crisp graphics/text and simple colors. Use high-quality JPG/WebP for photo-heavy banners to keep file size smaller.
Why does my banner look blurry after compression?
Text and fine details suffer first. Keep text large, avoid thin fonts, and don’t over-compress—try a slightly higher quality setting.
