Pick a platform and slot — Instagram post or story, a YouTube thumbnail, an X header — and your photo is resized to those exact pixels, in your browser.
Choose crop-to-fill for a clean edge-to-edge result, or fit-with-a-background when you don't want anything cropped. No watermark, nothing uploaded.
Exact dimensions for every platform
Each network wants a specific pixel size, and the wrong one gets cropped or blurred on upload. The Social tool resizes your image to the exact recommended size for Instagram (post, portrait, story), YouTube (thumbnail, banner), X, Facebook, TikTok, LinkedIn and Pinterest — all on your device, with a live preview of the crop.
Crop to fill, or fit with a background
Crop-to-fill scales the image to cover the frame and trims the overflow, so there are no bars — ideal for covers and thumbnails. Fit-with-a-background keeps the whole image visible and fills the spare space with white, black or transparency. Either way the output is exactly the target size, ready to upload.
How it works
Drop a photo and open the Social tool.
Pick the platform and the size you need.
Choose crop-to-fill or fit-with-background, then apply and download.
Like every pixelpix tool, this runs 100% in your browser: your file is never uploaded to a server, never leaves your device, and works even offline once the page has loaded.
Frequently asked questions
Which platforms and sizes are included?
Instagram (square, portrait, story), YouTube (thumbnail and banner), X/Twitter (post and header), Facebook (post and cover), TikTok, LinkedIn and Pinterest, at their current recommended pixel sizes.
Will my image be stretched?
No — the image is always scaled uniformly. Crop-to-fill trims the overflow; fit-with-a-background adds space around it. It's never distorted.
Is my photo uploaded to resize it?
No. The resize happens entirely in your browser, so the photo never leaves your device.
