Overview
You’ve taken a beautiful photo, but when you upload it to Instagram, it gets cropped weirdly or looks blurry. Sound familiar? That’s because Instagram expects specific image sizes. If your picture doesn’t match, the app chops off the edges or stretches it. For influencers, brands, or anyone who cares about their feed, that’s a nightmare.
Our Instagram post resizer solves this in seconds. No sign-ups, no watermarks, and your image never leaves your device. Let’s break down everything you need to know.
How to Resize Images for Instagram (4 Simple Steps)
- Upload your image – Drag and drop any photo into the box above, or click to browse.
- Pick your format – Choose square, portrait, or landscape. We show the exact pixel dimensions.
- Click “Resize for Instagram” – The tool instantly scales your image to fit the perfect size, adding a white background if needed.
- Download and post – Save the new image and upload it to Instagram. It will look crisp and uncropped.
Instagram Image Sizes Explained
Instagram uses three main aspect ratios for feed posts:
- Square (1:1) – 1080 x 1080 pixels. Classic post, works for almost everything.
- Portrait (4:5) – 1080 x 1350 pixels. Taller images, great for showing more vertical detail.
- Landscape (1.91:1) – 1080 x 566 pixels. Wide images, perfect for scenic shots.
Using the correct size ensures Instagram doesn’t compress or crop your photo. Our Instagram post resizer handles all three.
Why Image Quality Matters on Instagram
Instagram compresses images that don’t match their recommended dimensions. This can make your photo look pixelated or blurry. High‑quality images get more engagement – likes, comments, and shares. A professional feed builds trust with your audience. By using the right dimensions from the start, you keep every detail sharp.
