Questions
What size should a instagram post be?
1080 by 1080 pixels, saved as JPG, up to 30 MB. Anything larger is scaled down by the platform, usually with worse resampling than doing it yourself; anything smaller is stretched and looks soft. This page is preset to those numbers, so you can drop a file in and download the result. Spec last checked 2026-09-19.
Does cropping reduce the file size?
Yes, because there are fewer pixels to store. A crop that keeps half the area will usually produce a file somewhere near half the size, though the exact figure depends on how detailed the part you kept is.
How do I crop to an exact aspect ratio?
Pick a ratio and the selection locks to it: dragging any handle keeps the shape, and dragging the box to an edge shrinks it rather than distorting it. The readout under the image shows the pixel size and the ratio of the current selection at all times.
Are my images uploaded anywhere?
No. Image Cropper runs entirely inside your browser using the Canvas API. The file is read from your device, processed on your device, and the result is handed straight back to you. It never travels to a server, so there is nothing for us to store, log or leak.
Is it free, and is there a limit?
It is free with no account and no watermark. Because the work happens on your own hardware there is no per-image cost to us, so there is no quota. The only real limit is your device's memory: images beyond roughly 40 megapixels are refused rather than crashing the tab.
