Images for social media

Every page that makes a picture the size a platform shows it at: the size chart, a resize page for each post, cover and thumbnail, makers for thumbnails, collages and memes, and video for vertical feeds. Everything runs in your browser.

Frequently asked questions

Which size should I use for each platform?
The size chart lists them all with their ratios: 1080 × 1080 for a square Instagram post, 1080 × 1350 for a portrait one, 1080 × 1920 for Stories, Reels and TikTok, 1280 × 720 for a YouTube thumbnail and 1500 × 500 for an X header. Each size has a page that resizes to it.
Will my picture be cropped?
With Fill and crop, whatever lies outside the frame is trimmed and you choose where the frame sits; Fit inside keeps the whole picture and pads it instead. Platforms crop on their side too — profile pictures into a circle, covers on phones — so keep faces and text near the middle.
Are the sizes up to date?
They are the sizes the platforms’ own help pages gave in September 2026, and the date is shown on the size chart. Platforms change them now and then.
Is anything uploaded?
No. Pictures are resized and videos cropped and encoded on your device; nothing is sent to Nouplo or to the platform until you post it yourself. It is free with no account, and Pro removes the free plan’s limits.
