How to: Social Media Image Resizer
- Upload one or more images.
- Pick the platform and format, then choose blurred fit, colour fit or crop.
- Download images sized exactly for that platform.
Every social network wants a different shape. A landscape photo that looks great on X gets cropped awkwardly in an Instagram Story, and a Facebook cover needs a very wide banner. Choose a preset and this resizer delivers an image at exactly the right pixel size – keeping the whole picture with a blurred or coloured background, or filling the frame and letting you choose which part is kept.
Common uses
- Turn one photo into versions for Instagram, Facebook, LinkedIn and X in minutes.
- Make YouTube thumbnails and channel banners at the right resolution.
- Create Story and Reel backgrounds from landscape photos.
- Prepare Open Graph share images for websites and blogs.
Tips for best results
- Use portrait 1080×1350 on Instagram – it takes up more space in the feed than square.
- Turn on the safe-zone guide to keep text away from areas covered by buttons.
- Use “Fill frame” for photos with the subject in the centre.
- Export JPG for photos and PNG for graphics with text.
Why exact sizes matter
When you upload an image that does not match the expected shape, the platform crops or shrinks it automatically, often cutting off heads or text. Uploading at the recommended size also avoids extra compression on some networks, which keeps photos sharper. All presets are listed with their pixel dimensions so you know exactly what you get.
Safe zones for Stories and banners
Stories, Reels and TikTok videos show the profile name at the top and reply buttons at the bottom, and channel banners are cropped differently on TV, desktop and phone. The optional safe-zone guide on the preview marks the central area that stays visible everywhere; the guide is not included in the download.
Batch and private
Resize a whole set of images to the same format in one go and download them as a ZIP. Nothing is uploaded – resizing runs on your own device.

Frequently asked questions
What is blurred-background fit
Instead of cutting off parts of your photo, the whole image is placed in the centre and the empty space is filled with a soft, blurred version of the same photo – the look you see on many Stories and Reels.
Are the sizes up to date
The presets follow the recommended dimensions published by each platform in 2025–2026, such as 1080×1350 for Instagram portrait posts and 1280×720 for YouTube thumbnails. Platforms change their layouts occasionally, so check their help pages for new formats.
