Frequently asked questions
What's the difference between crop and blur fill?
Crop fills the whole frame and trims what doesn't fit. Blur fill keeps your entire image and fills the empty space with a soft, blurred copy of it, which is popular for stories and Reels.
Are these the current sizes?
They're the sizes the platforms recommend for upload in 2026, such as 1080 × 1350 for Instagram portrait posts and 1280 × 720 for YouTube thumbnails. Platforms change them occasionally.
Is my image uploaded?
No. Resizing happens on your device.
