Common questions
What image size works best on Instagram?
1080×1350 pixels (4:5) is the safe default for the feed. Instagram rejects images outside 4:5 to 1.91:1, so very tall or very wide images need cropping first.
Can I post an image to YouTube?
No. YouTube only accepts video, so switch the post to a video or remove YouTube from its platforms.
Which image formats can a TikTok photo post use?
JPG or WebP. TikTok doesn't accept PNG or GIF for photo posts.
