Sizing Images for Social Media
Why every platform needs a different size
Each social network crops and displays images according to its own fixed dimensions, and uploading the wrong size means the platform decides what to cut — often chopping off heads, logos, or key text. Instagram, YouTube, Facebook, X, LinkedIn, and Pinterest each expect different aspect ratios for posts, stories, thumbnails, and cover images.
Resizing to the exact recommended dimensions before you upload guarantees your image appears the way you intended, with nothing important lost to automatic cropping.
Presets that save time
Picovert includes presets for the most common social formats, so you do not have to memorize pixel dimensions. Pick the platform and placement — a square 1080×1080 feed post, a 1080×1920 vertical story, or a 1280×720 video thumbnail — and the image is sized correctly in one step.
Using presets also keeps a consistent look across a campaign, since every image lands at the same, platform-correct proportions.
Quality and privacy
Resizing down to social dimensions also makes files dramatically smaller, which helps your posts upload faster and display sharply on mobile. Starting from a high-resolution original gives the cleanest result after downscaling.
All resizing happens locally in your browser, so your photos — including unpublished campaign material — are never uploaded to a third-party server.
