What Is This Tool For?

Every social platform expects a different image size — an Instagram Story is tall, a Facebook cover is wide and short, a YouTube thumbnail is a specific 16:9. Uploading the wrong ratio means the platform crops it for you, often awkwardly, cutting off a face or a headline mid-word. This tool lets you pick the exact preset and see the crop before you download, so you control the composition instead of leaving it to whatever the platform decides.

Which Presets Suit Which Photos

  1. 1Square and near-square formats (Instagram Post, Portrait)Forgiving for most photos since they're close to a typical camera's native ratio — a small center crop usually loses very little.
  2. 2Tall formats (Instagram Story, Pinterest Pin)Aggressive crops on a landscape original — a wide photo squeezed into a tall frame will lose most of its left and right edges, so these work best starting from a portrait-oriented photo.
  3. 3Wide formats (Facebook Cover, YouTube Thumbnail, X Post)The opposite problem — a portrait photo loses a lot of its top and bottom in a wide crop, so a landscape original with the subject centered works best here.

Good to Know

  • Every preset uses a "fill and crop" resize — the image is scaled up until it covers the entire frame, then the excess is trimmed from the edges, so nothing gets stretched or squashed.
  • For portrait subjects (like a person), a tightly cropped original may lose part of the subject in a very different aspect ratio (e.g. a square photo going into a tall Story) — start with a photo that has extra space around the subject when possible.
  • Platforms occasionally update their recommended sizes — these presets reflect commonly used values, so double-check the platform's current guidelines for anything mission-critical.
  • If a preset's automatic center crop cuts off the wrong part of your photo, crop it manually first with the Crop tool to control exactly what stays in frame, then resize.
  • Nothing is uploaded — the resize happens entirely in your browser.

Frequently Asked Questions

Will my photo get stretched or distorted?

No — the tool scales the image to fill the target frame proportionally, then crops the overflow from the center. Nothing is squashed or stretched out of shape.

Why is part of my image cut off after resizing?

Because the target aspect ratio (e.g. a square Instagram post) is different from your original photo's ratio, filling the frame without distortion means trimming some content from the edges — this is the same "cover" behavior most photo apps use.

How do I control exactly what part of the photo stays in frame?

The automatic crop is always centered, so if your subject isn't centered in the original, crop the photo manually first with the Crop tool to reposition it, then run it through this resizer.

Which format should I download in?

The output keeps your original image's format where possible (JPEG or WebP) — all major platforms accept both.

Do these exact pixel sizes still match what platforms expect in 2026?

The presets reflect commonly published values for each platform. Since platforms do update their recommended sizes from time to time, double-check the platform's current help documentation before a size-critical use, like a paid ad.

Is my image uploaded to a server?

No. Everything is processed locally using the Canvas API in your browser.
