About this tool
Every network shows pictures in its own shape. A wide photo posted to Instagram gets cropped, a vertical one gets bars on a Facebook cover, and a thumbnail with the wrong ratio puts your title under the play button. Resizing to the exact size before you upload means you decide what is cut, not the platform. Pick a placement, upload your picture and the tool does the sums.
There are two ways to match the frame. Fill scales the picture until it covers the whole frame and trims what sticks out, and the focus choice decides which side is kept, so faces at the top of a photo can stay in view. Fit keeps the whole picture inside the frame and fills the leftover space with the background colour you pick, which suits logos, charts and text graphics you cannot afford to cut.
The sizes listed are widely used recommended dimensions and platforms change them from time to time, so check the current guidance for a paid campaign. Allow for edge trimming too: banners and covers are often cropped differently on phones, so keep important text away from the borders. Results can be saved as JPG, PNG or WebP, and the new file carries no camera metadata. Keep your original picture for other uses.
Frequently asked questions
What size should an Instagram post be?
A square post is commonly 1080 by 1080 pixels, a portrait post 1080 by 1350 pixels, and a story or reel cover 1080 by 1920 pixels. Portrait takes up more of the feed, so it is a popular choice. Choose the placement in this tool and it creates the exact size.
Should I choose Fill or Fit?
Choose Fill when the picture can lose its edges, such as a photo, because it covers the whole frame cleanly. Choose Fit when nothing can be cut, such as a logo, a poster or text, because the whole picture stays visible on a background colour you pick.
Why does my banner look cropped on a phone?
Covers and headers are shown at different shapes on desktop and mobile apps, so each edge may be trimmed. Keep faces, logos and text well inside the middle of the image, away from the borders, and test the upload on a phone before you publish.
Are these sizes always correct?
They are commonly recommended sizes, but networks change their layouts and guidance. Treat them as a safe starting point, and check the platform help page when you build a paid ad or a brand banner. The result is a correct file at the size shown on this page.
Is my picture stored on your server?
No. The file is held in memory only while it is resized and is discarded when the page finishes loading. It is not saved to disk or shared. The resized picture in the result exists only on that page, so download it before you leave.
