Social Media Image Resizer
Social Media Image Resizer
What is this tool?
A browser-based resizer with the published sizes for Instagram, Facebook, X, YouTube, LinkedIn, Pinterest, TikTok and WhatsApp built in. Crop-to-fill scales the picture until it covers the frame and crops the overflow from the edge you choose; fit-whole-image scales it down inside the frame and fills the rest with a blurred copy, a solid colour or transparency. Every selected size is previewed before you export, and the whole set downloads together.
When to use it
- Publishing one photo as an Instagram post, a story and a Facebook post at once
- Making a YouTube thumbnail and a channel banner from the same artwork
- Fitting a portrait photo into a wide LinkedIn or X header
- Preparing a full set of platform sizes for a campaign
- Avoiding the automatic crop a platform applies to an odd-shaped upload
How to use it
- 1Drop in one image
- 2Tick the platform sizes you need — or use "Select all" on a platform
- 3Choose Crop to fill (and which part of the picture to keep) or Fit whole image with a background
- 4Pick a format and quality — JPEG for photos, PNG or WebP when you need transparency
- 5Check the previews, then download all the sizes as a ZIP
Frequently asked questions
Which sizes are included?
Twenty-two: Instagram square, portrait, landscape, story and profile; Facebook post, page cover, story, event cover and profile; X post and header; YouTube thumbnail, channel banner and Shorts cover; LinkedIn post, personal banner and company cover; Pinterest standard and square pins; a TikTok cover; and a WhatsApp status. Each one shows its exact pixel dimensions, so you can see what you are getting.
Should I crop to fill or fit the whole image?
Crop to fill looks best when the subject is near the middle — pick the part of the picture to keep, and nothing is letterboxed. Fit whole image is for artwork or text you cannot cut into, and the blurred background is the usual way to pad a photo into a story frame.
What happens if a size is bigger than my image?
The tool warns you which sizes need enlarging and exports them anyway — enlarging invents pixels, so it looks softer. A YouTube banner at 2560×1440 from a 1080p photo is the common case; a higher-resolution original is the only real fix.
Is my image uploaded?
No. Decoding, resizing, encoding and the ZIP are all built in your browser.
