Social crop
Exact sizes for every platform, with the crop where your subject is rather than stuck in the middle of the frame — and a warning before anything gets upscaled.

4:5, the tallest the feed shows uncropped. Occupies the most screen of any feed size.
Every size, in one table
These are display dimensions, not upload limits. Every platform below re-encodes what you send it, so pixels beyond these sizes are discarded after costing you the upload.
Why centring is the wrong default
A crop has to throw something away, and which part matters. Taking 9:16 out of a landscape photograph discards about three-quarters of the frame — centred, that usually means the horizon survives and the subject does not.
So the crop here follows a point you choose. The rectangle stays the correct ratio and is clamped inside the image, which means dragging it to an edge slides the framing rather than leaving an empty band down one side.
Frequently asked questions
What size should an Instagram post be?
1080×1350 for the feed. That is 4:5, the tallest ratio the feed displays without cropping, so it occupies more screen than a square. 1080×1080 square is safe but gives up that vertical space, and 1080×1920 is for Stories and Reels rather than the feed.
Why does the crop not have to be centred?
Because subjects rarely are. Every automatic cropper centres the frame, which for a 9:16 crop of a landscape photograph is usually the one crop nobody wanted. Clicking the preview anchors the crop where you point it, and the rectangle is pushed back inside the frame so it can never hang off an edge.
What does the upscaling warning mean?
That the area you are cropping is narrower than the target width, so the export has to be enlarged to fill it. Enlarging invents pixels, and the result looks soft in a way that is hard to diagnose afterwards. The fix is a larger source file, not a different setting.
Should I upload the largest image I can?
No. Every platform here re-encodes on upload, so anything beyond the displayed size is discarded after costing you bandwidth. These presets are the dimensions each platform actually shows, which is the useful ceiling.
Does cropping remove my photo's metadata?
Yes, as a side effect. The crop is rendered through a canvas, and a canvas holds pixels only, so EXIF and GPS do not survive. If removing metadata is the actual goal rather than a bonus, the EXIF remover does it without changing the framing.
Is my photo uploaded?
No. It is decoded, cropped and re-encoded entirely on your device with the File API and a canvas. Nothing is transmitted.
