Overview

Bulk Images Resize for Instagram allows you to quickly prepare up to 10 images at once for various Instagram formats, including stories, feed posts, reels covers, and profile photos. By selecting preset aspect ratios and configuring fit methods like cover cropping or blurred backgrounds, you can optimize your JPEG, PNG, or WebP images for social media without manual editing.

When to use

  • When preparing a batch of photos for an Instagram carousel post and you need them all resized to a uniform square or portrait aspect ratio.
  • When converting landscape photos into vertical 9:16 stories or reels covers without cropping out important details, using a blurred background fit.
  • When updating your brand's profile picture or publishing multiple feed posts and wanting to ensure they meet Instagram's exact dimension guidelines.

How it works

  1. 1Upload up to 10 image files in JPEG, PNG, or WebP format.
  2. 2Select your target Instagram content type, such as Feed Post, Stories, or Reels Cover, to automatically apply the correct dimensions.
  3. 3Choose your fit method (like cover or contain with a blurred background), set the output format and quality, and click process to download the resized images.

Use cases

  • Batch resizing a series of landscape travel photos into 9:16 vertical images with blurred backgrounds for Instagram Stories.
  • Preparing a 10-image carousel post by converting mixed-aspect-ratio product photos into uniform 1080x1080 square JPEGs.
  • Resizing a high-resolution portrait photo to exactly 1080x1350 for a vertical feed post while optimizing file size and quality.

  • Basic image canvas extension tool for adding space around images with various fill strategies

  • Extend image canvas with blurred background, perfect for portraits, product photos, and professional presentations

Who it's for

Best for

  • Process images in the browser.
  • Workflows where Instagram Content Type matters, such as Profile Photo (1080×1080, 1:1) or Feed Post - Square (1080×1080, 1:1).
  • Repeatable jobs with images and the same settings every time.

Not ideal for

  • Fully automated batch jobs — this page is built for interactive use; use the API endpoint for scripts.
  • Files in formats this tool does not accept — it works with .jpg, .png, .webp input.

Edge cases & common failures

  • Very large files

    Large files take longer and can hit browser memory limits — try a smaller sample first.

  • Skipping the output check

    Compare the first rows or pages of the output with the input before using it in production.

  • Files from unusual exporters

    Some files use format variants that do not convert cleanly — if the output looks wrong, re-save the file from the app that created it and try again.

Examples

1. Preparing a 10-Photo Carousel Post

Social Media Manager

Background

A social media manager needs to upload a carousel post featuring 10 different product shots, but the original photos have varying aspect ratios and file sizes.

Problem

Instagram carousels require all images to share the same aspect ratio, and manually cropping each photo in editing software takes too much time.

How to use

Upload all 10 product images, select 'Carousel Posts (1080×1080, 1:1)' as the content type, set the fit method to 'cover', and choose JPEG output at 85% quality.

Content Type: Carousel Posts, Fit Method: Cover, Output Format: JPEG, Quality: 85

Outcome

Ten perfectly cropped 1080x1080 square JPEG images ready for immediate upload as a cohesive Instagram carousel.

2. Converting Landscape Photos for Stories

Travel Blogger

Background

A travel blogger wants to share horizontal landscape photos on their Instagram Stories without cropping out the sides of the scenery.

Problem

Directly uploading landscape photos to Stories results in large blank black bars on the top and bottom, which looks unprofessional.
