Social Media Resizer

One image, every platform size, in one click, with a ZIP download.

Upload one image and this page renders it at every platform size below, in one click. Pick Cover to fill each frame (edges cropped) or Contain to fit the whole image inside (bars filled with the colour you pick), tick only the sizes you want, and download them one by one or as a ZIP. Sizes were checked against platform guides in November 2026 and are shown in the table so you can spot a stale one: platforms change specs without notice, and a platform's own help page beats this table when a post matters. A custom size box is included for any size the table misses.

Honest limits. Resizing cannot add detail: a 500 pixel wide source stretched to a 2560 pixel banner will look soft, and no setting fixes that. Cover mode crops: a square crop of a wide photo throws away the sides, so check the preview before posting, especially where text or faces sit near an edge. JPG output drops transparency (transparent pixels become the fill colour) and recompresses, so keep the PNG original if you plan to edit again. File sizes are not promised: a busy photo at 1080 by 1920 PNG can be several megabytes, and some platforms cap uploads, so check the platform's file-size limit for the post you are making.

One image, fourteen frames, and why the numbers differ

Platforms do not share a size because they do not share a screen shape. A phone feed is vertical, so Instagram portrait posts are 1080 by 1350 (4:5) and stories are 1080 by 1920 (9:16). A desktop feed is wide, so a LinkedIn post image is 1200 by 627 (about 1.91:1) and a YouTube thumbnail is 1280 by 720 (16:9). Pinterest pins are tall at 1000 by 1500 (2:3) because the board is a vertical masonry grid. The square 1080 by 1080 survives everywhere as the safe fallback, which is why it is ticked by default along with the portrait and story sizes.

Cover and Contain answer different questions. Cover asks: fill this frame completely, and cut whatever does not fit. A 16:9 photo made into a 9:16 story loses most of its width, so faces and text near the sides vanish. Contain asks: show the whole image, and fill the leftover bars with a colour. Nothing is cut, but a wide photo inside a tall frame becomes a small strip with big bars. For posts where the whole image matters, Contain is the honest choice; for posts where the frame matters more than the edges, Cover is. The preview shows both, so the choice is visible before anything is downloaded.

Cover maths, worked out

Cover scales the image until the frame is filled in both directions, then centres the crop. A 4000 by 3000 photo into 1080 by 1920 scales to 2560 by 1920 (height is the limit), then crops the width from 2560 to 1080, cutting 740 pixels from each side. That is why a centred subject survives Cover and an edge subject does not.

The size table, and its expiry date

Instagram square 1080 by 1080, portrait 1080 by 1350, story and reel 1080 by 1920; LinkedIn post 1200 by 627, profile 400 by 400, cover 1584 by 396; X post 1280 by 720, profile 400 by 400; YouTube thumbnail 1280 by 720, banner 2560 by 1440; TikTok 1080 by 1920; Pinterest pin 1000 by 1500; Facebook feed 1080 by 1080, link preview 1200 by 630. Checked November 2026. Treat any of these as stale after a platform redesign and check the platform's help page.

Cover fills the frame completely and crops the edges that do not fit. Contain shows the whole image and fills the leftover bars with your chosen colour. Cover suits frames where the middle matters; Contain suits images where nothing may be cut.

No. Resizing cannot add detail. A 500 pixel source stretched to a 2560 pixel banner will look soft, and upscaling is a last resort, not a fix. Start from the largest original you have.

Platforms redesign feeds and change recommended sizes without notice. The table on this page was checked in November 2026; a platform's own help page beats it when a post matters.

No. JPG has no transparency, so transparent pixels become the fill colour and the image is recompressed. Keep the PNG original if you plan to edit again.

No. Resizing runs in your browser. Nothing leaves your device.
