How do I change a photo to 9:16 without cropping it?
Choose TikTok, Reels or Shorts above (1080 × 1920, 9:16), add your photo, and keep "Blurred photo" selected. The whole photo stays visible in the middle, and the empty space above and below is filled with a soft, blurred copy of the same photo, the look you see on most Stories and Reels. Download it as JPG, PNG or WebP.
How to resize an image to any aspect ratio
- Pick the size you need from one of the four menus (vertical video, posts, video & web, shops), for example TikTok 9:16, Instagram 4:5 or YouTube thumbnail 16:9, or type your own width and height.
- Add your photo: JPG, PNG, WebP or HEIC from an iPhone.
- Choose how to fill the empty space: a blurred copy of the photo, a solid colour, or crop the photo so it fills the frame.
- Drag the photo to position it and use Photo size to make it bigger or smaller.
- Choose JPG, PNG or WebP and press Download. The file is exactly the size of the preset.

Blur, colour or crop: which fill should I use?
- Blurred photo: best for social media. Nothing is cut off and the background matches the colours of your photo.
- Colour: best for products and shops. White is standard for Shopify and Amazon listings.
- Crop to fill: when you don't want any border. Drag to choose which part of the photo stays.
How do I resize an image for Instagram without cropping?
Pick 4:5 for a portrait feed post, 1:1 for a square post or 9:16 for Stories and Reels, then choose a blurred or coloured background. The whole photo stays visible and the empty space is filled, so Instagram doesn't cut off heads or text. Download the result and upload it as it is.
9 16 converter: how do I make a horizontal photo vertical?
Choose 9:16 and the aspect ratio changer places your wide photo in the middle of a vertical 1080 × 1920 frame, with a blurred copy of the same photo above and below. This is the usual look for TikTok, Reels and YouTube Shorts, and it works for screenshots and product photos too.
Questions
Is my photo uploaded anywhere?
No. The photo is resized and drawn by your own browser. Nothing is sent to Okviro Tools or any other server.
What is a 9:16 aspect ratio?
9:16 is a tall, vertical frame: 9 units wide for every 16 units high, the shape of a phone screen held upright. At full HD it is 1080 × 1920 pixels and it is used by TikTok, Instagram Reels and Stories, and YouTube Shorts.
How do I post a horizontal photo on Instagram Stories without cropping?
Choose "Instagram Reels & Stories" (1080 × 1920) and keep "Blurred photo". The whole horizontal photo stays in the middle and the space above and below is filled with a blurred version of it.
What size is a YouTube thumbnail?
1280 × 720 pixels, a 16:9 ratio. Use the YouTube thumbnail preset; JPG keeps the file small.
Does the image lose quality?
Only if your photo is smaller than the target size, because it then has to be enlarged. JPG and WebP are saved at high quality; choose PNG for the best quality on graphics and screenshots.
Can I use an iPhone HEIC photo?
Yes. HEIC photos are converted to JPG automatically in your browser.
