Why use an Instagram Resizer?
Instagram has strict aspect ratio limits. If your photo isn't 4:5 (Portrait) or 1:1 (Square), the app will automatically crop out important details or compress the quality heavily.
- Portrait (4:5) - 1080x1350px: This size takes up the most screen real estate on mobile devices, leading to higher engagement rates.
- No Crop Mode: Our tool intelligently adds background fill (White, Black, or Blur) to fit your landscape photos into the 4:5 frame without losing any part of the image.
How to make a "No Crop" Instagram Post?
- Upload your photo (or multiple photos).
- Click the "Portrait (4:5)" preset button.
- Check "Fit to Canvas" and choose Blur BG for a modern look.
- Download. You will get a 1080x1350 image with your original photo centered and a blurred background.
Is it safe?
Yes. All processing happens locally in your browser. Your photos are never uploaded to any server, ensuring 100% privacy.
