Why Use PDFBro to Resize Images
Frequently Asked Questions
What size should an Instagram Story image be?
1080x1920 pixels is the native Story resolution. This 9:16 aspect ratio fills the entire phone screen without black bars. Images smaller than 1080x1920 look pixelated; larger images are downscaled by Instagram. PDFBro resizes to the exact native dimensions for crisp, full-screen Stories.
Can I use landscape photos for Instagram Stories?
Landscape images (16:9 or 4:3) won't fill an Instagram Story. They'll have large black bars on top and bottom. Resize to 1080x1920 with PDFBro first — you can either crop the center or add a background to convert horizontal photos to the vertical Story format.
What file type works best for Instagram Stories?
JPEG for photos (smaller file, faster upload). PNG if your Story graphic includes text, logos, or needs transparency. Both formats work perfectly at 1080x1920 in PDFBro's resizer.
How do I resize a portrait photo to exact Instagram Story size?
Upload your portrait photo to PDFBro's resize tool at pdfbro.tech/tools/resize-image, enter 1080 width and 1920 height, and download. If your photo isn't exactly 9:16, the tool scales it to fit while maintaining the aspect ratio. For an exact fill, crop your photo to 9:16 first.
