Every current size for Instagram, TikTok, X, LinkedIn, Facebook, YouTube, Pinterest and Twitch. Free, no signup, and the file never leaves your device.
One image, six platforms, six different correct sizes.
Social Media Resizer is one of 22 free browser tools on IMGX Studio, filed under Resize & crop. It runs entirely on your own device: the image is read in the browser, processed there, and never uploaded to a server, so there is nothing to delete afterwards and no account to create.
Open the tool, drop in an image, adjust the settings, and download the result. It works on desktop and mobile, there is no watermark, and there is no limit on how many times you use it.
