Auto-fit to 1080×1920px for Instagram
The Instagram Story / Reel size is 1080×1920 pixels, an aspect ratio of 9:16. This is the recommended dimension for Stories and Reels on Instagram. Keep text in the middle 80% — the top and bottom are covered by the UI. This tool resizes any image to exactly 1080×1920px in your browser — you can zoom, reposition, and choose whether to fill the frame (cropping edges) or fit the whole image (adding whitespace), then download a perfectly-sized PNG.
To resize an image for Instagram: upload your image above, use the zoom and position sliders to frame it inside the 1080×1920px area, choose Fill (to crop and fill the whole frame) or Fit (to keep the entire image with white padding), and download. The result is exactly 1080×1920px — the correct Instagram Story / Reel size — so it uploads to Instagram without any awkward cropping. Everything happens in your browser, so your image is never uploaded to a server.
For the best Instagram Story / Reel: start with a high-resolution image so it stays sharp at 1080×1920px, keep important content (faces, text, logos) in the center safe zone, and export as PNG for crisp edges or JPEG for smaller file size. Keep text in the middle 80% — the top and bottom are covered by the UI. Using the exact 9:16 ratio prevents Instagram from auto-cropping your image in unexpected ways, which is the most common reason posts look wrong after uploading.
The Instagram Story / Reel should be 1080×1920 pixels with a 9:16 aspect ratio.
A Instagram Story / Reel uses a 9:16 aspect ratio (1080×1920 pixels).
Use the Fit mode in this tool to keep your entire image with white padding, or Fill mode with the position sliders to control exactly what gets cropped to the 9:16 frame.
