Free YouTube Image Resizer

What is a YouTube image resizer?

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

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

Every YouTube image size in 2026

Here are all six sizes:

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

Tips for YouTube images

A few sizes come with rules worth knowing:

• Video thumbnail, phone upload – A smaller 16:9 that fits the 2 MB limit for uploading from a phone.
• Channel banner – Keep text and logos in the middle 1,235 × 338 at the minimum size; the rest is cropped on phones and computers.
• Profile picture – YouTube gives no upload size, only that it renders at 98 × 98 as a circle; a bigger square stays sharp on large screens.

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

YouTube upload rules

Here's what YouTube accepts:

• Formats – JPG, PNG.
• File limits – 1 MB, 2 MB from a phone, 6 MB, 15 MB, 50 MB, 50 MB on a computer, 2 MB on a phone, 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 Panama City at sunset, cut to four YouTube 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 YouTube's own pages, checked on October 1, 2026:

• YouTube Help: Manage your channel branding
• YouTube Help: Add custom thumbnails

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 YouTube image resizer for?

It's for anyone posting on YouTube:

• YouTube thumbnail downloader – creators studying other thumbnails
• YouTube keyword tool – creators picking a video's topic
• Remove background – creators cutting themselves out for a thumbnail
• Compress image – anyone uploading a thumbnail from a phone

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