Questions

Frequently Asked Questions

Technical specifications and best practices for social media image resizing and aspect ratio calibration.

1

What are the exact pixel dimensions and aspect ratio for Instagram Stories and Reels?

Instagram Stories and Reels use a 9:16 aspect ratio with exact pixel dimensions of 1080 x 1920 px. This vertical format fills modern smartphone displays from top to bottom.
2

How does the blurred background feature work for horizontal photos in 9:16?

When you upload a horizontal or landscape photo, the tool keeps your entire picture uncropped in the center while generating a softened, frosted duplicate of your photo as the backdrop to seamlessly fill the vertical 9:16 canvas.
3

Where is the safe zone for text and stickers on Instagram Stories and TikTok?

Keep text, stickers, and logos within the central 1080 x 1420 px area. Leave roughly 250px clear at the top (profile avatar and account name) and 250px clear at the bottom (message reply box and share icons).
4

Can I resize vertical photos for Instagram Reels, Highlights, and TikTok simultaneously?

Yes. Instagram Stories, Instagram Reels, Facebook Stories, TikTok, and YouTube Shorts all share the exact same 1080 x 1920 (9:16) standard, making your exported file universal across all short-form platforms.
5

What is the maximum recommended file size for Instagram Stories?

Instagram accepts image uploads up to 30 MB, but files under 4 MB render fastest without triggering aggressive compression algorithms. Our tool exports optimized 95% quality JPGs that load instantly.
6

Does this tool run locally in my browser without server storage?

Yes. All resizing, canvas blurring, and cropping computations happen 100% on your device using client-side JavaScript. Your images never pass through or get saved on any remote servers.
