Free Instagram Image Resizer

What is a Instagram image resizer?

A Instagram image resizer cuts a photo to the exact pixel sizes Instagram uses, so nothing gets cropped or blurred when you upload it.

This one has every Instagram size in one place. It makes each file at a high quality and keeps it under Instagram's upload limit.

Every Instagram image size in 2026

Here are all 10 sizes:

The resizer has every size in this table. Pick the ones you need, and each becomes its own file.

Tips for Instagram images

A few sizes come with rules worth knowing:

• Portrait post, 3:4 – The tallest post Instagram keeps: photos can be 1.91:1 to 3:4, and wider or taller ones are cropped to fit.
• Profile photo – Instagram's help gives no size for profile photos; they show as a circle, so keep the face in the middle. A square at the 1080 px width Instagram uses stays sharp.

The resizer draws the safe areas and round crops on each preview, so you see them before you download.

Instagram upload rules

Here's what Instagram accepts:

• Formats – JPG, PNG.
• File limits – 30 MB, depending on where the image goes.

When a file comes out over a size's limit, the resizer makes it again at the best quality that fits, the same size.

Examples

This is my own photo of Stockholm at sunset, over Fotografiska, cut to four Instagram sizes by this resizer:

I kept the sunset in every crop, the part of the photo that matters most.

Compared with Buffer

Buffer's free image resizer has a page for most networks. I ran the same photos through both on October 1, 2026:

On the same photos, cut to LinkedIn, Instagram, Pinterest and YouTube sizes, this resizer's JPGs scored within about a point of Buffer's and were 13% to 24% smaller.

The first crop matters too. On my Panama City photo, Buffer's LinkedIn cover started on the houses below the sunset, and this resizer's started on the sunset.

How I tested

I tested on October 1, 2026, with two of my own photos, Stockholm and Panama City at sunset, 1,536 × 2,048 each.

Above 80 means the same side by side at 100%. Both tools' files scored 85 to 88 where both cut the same area.

Where these sizes come from

Every size on this page is from Instagram's own pages, checked on October 1, 2026:

• Instagram Help: Reel size and aspect ratios
• Instagram Help: Image resolution of photos you share
• Meta Ads Guide: image ads on Instagram Feed
• Meta Ads Guide: image ads on Instagram Stories
• Meta Business Help: Design requirements for Instagram Stories ads

When a page gives a range instead of one size, I picked the sharpest size inside it and said so in the tips.

Who is the Instagram image resizer for?

It's for anyone posting on Instagram:

• Instagram grid maker – creators planning their profile grid
• Instagram carousel splitter – anyone turning a wide photo into a carousel
• Instagram character counter – people writing captions
• Link in bio generator – creators sending people to their links

Social media managers use it to make every Instagram size from one photo in a minute.
