What is Story Size Converter?
The Story Size Converter is a free browser-based tool that converts any image or horizontal photo to the 9:16 vertical format required for Instagram Stories, TikTok videos, Facebook Stories, and Snapchat. Social media stories all use the 9:16 vertical format (1080×1920 pixels) — images that are not this ratio appear with blurred edge-fill or black bars, which looks unprofessional and reduces engagement. MediaDrop's tool automatically fits your image into the 9:16 frame with smart crop positioning so your content always displays perfectly.
How to use Story Size Converter
- Step 1: Upload your image by clicking the upload area or dragging it onto the tool.
- Step 2: The tool automatically resizes and centers your image within a 9:16 (1080×1920px) frame.
- Step 3: Adjust the vertical position slider to move your image up or down within the frame.
- Step 4: Choose your background style — blurred (matches your image colors), solid color, or transparent.
- Step 5: Preview the result to confirm your image is positioned correctly.
- Step 6: Download your Story-ready image at full 1080×1920px resolution.
Tips for better results
- Use blurred background for best results. The blurred background option samples colors from your image and creates a matching gradient — much more professional than black bars or a solid color that clashes with your image.
- Reposition for portraits. When converting portrait photos to Story size, use the position slider to ensure the face is visible in the center-upper portion of the frame — where viewers' eyes naturally go first.
- Stories have UI safe zones. Keep important elements away from the top 60px (where the profile handle and time appear) and bottom 250px (where interactive elements like polls and CTAs appear).
- Convert product photos for Story ads. Product photos are typically horizontal. Use the Story Size Converter to create vertical versions suitable for Instagram Story ads and organic story posts.
- Convert landscape thumbnails for Story promotions. When promoting a YouTube video via Instagram Stories, convert the YouTube thumbnail (16:9) to 9:16 Story format so it fills the entire screen.
- Batch convert multiple images. Convert each image individually using the same settings for a consistent look across a series of Story slides.
Frequently Asked Questions
What is the correct size for Instagram Stories?
Instagram Stories should be 1080×1920 pixels (9:16 aspect ratio). This fills the full screen of modern smartphones. Images that are not 9:16 will have blurred edge-fill added automatically by Instagram.
What platforms use 9:16 vertical format?
Instagram Stories, Instagram Reels, TikTok, Facebook Stories, Snapchat, YouTube Shorts, WhatsApp Status, and Pinterest Idea Pins all use the 9:16 vertical format. Converting once to 9:16 creates content suitable for all these platforms.
Will my image be blurry after conversion?
If you start with a high-resolution image (at least 1080px wide), the converted Story image will be sharp. Very small source images may appear blurry after conversion because they are being upscaled.
Is the Story Size Converter free?
Yes. Completely free with no signup and no usage limits. All conversion happens in your browser.
Can I use this for TikTok covers?
Yes. TikTok cover images also use the 9:16 vertical format. Images converted with the Story Size Converter are correctly sized for TikTok video covers.
