Quick answer

Resize image for Instagram portrait post directly in your browser. Upload an image, use the prefilled settings, process it locally, and download the result.

How it works

The recommended size for a Instagram portrait post is 1080 × 1350 pixels (a 4:5 portrait frame). Uploading at the right dimensions stops the platform from cropping or softening your image. This page is preset to 1080 × 1350, so your image is sized correctly the moment you download it.

Upload your image.
Use the prefilled 1080 × 1350 Instagram portrait post preset.
Process the image and preview the result.
Download the resized Instagram portrait post image.

Tips for the best result

Start from a source at least 1080 × 1350 pixels so the Instagram portrait post preset never has to upscale and blur your image.
Keep faces, logos, and text clear of the edges so nothing important is lost in the 4:5 crop.
If the platform also limits file size, compress the result to a KB target after resizing.

Common mistakes to avoid

Do not edit the only copy of your image. Keep the original before using this page.
Do not judge the result by file size alone. Open the downloaded image and check important details.
Do not stretch the image to 1080 × 1350 if the aspect ratio does not match. Crop or contain it instead.

Example workflows

Use this page when a site asks for exactly 1080 × 1350 pixels.
Non-square outputs work best when the source is cropped or contained intentionally.
After downloading, inspect the file properties to confirm the final dimensions.
