About resizing to Instagram Post
Resizing to 1080 × 1080 changes the image's pixel dimensions, which also affects its file size. Shrinking stays crisp; enlarging beyond the original can look soft.
This preset is sized for Instagram Post. Everything runs locally in your browser, so your image stays private — no upload, queue or sign-up.
This sizes your image to exactly 1080 by 1080 pixels, the square format Instagram uses for standard feed posts and carousel slides. Start from an already-square crop so your subject isn't squeezed when it's fitted to the frame, and the feed won't crop your edges the way it does a landscape or portrait shot.
Frequently asked questions
How do I resize an image to Instagram Post?
Drag your JPG, PNG or WebP into the tool above — the size is already set to 1080 × 1080 pixels — and press Resize. FileTinker resizes it in your browser, then you download the result.
Will resizing to Instagram Post reduce the quality?
Resizing changes the pixel dimensions to 1080 × 1080. Scaling down stays crisp; scaling a small image up to 1080 × 1080 can look softer because there is no extra detail to add.
Does resizing keep the aspect ratio?
This preset resizes to exactly 1080 × 1080. On the main resizer you can lock the aspect ratio so width and height stay in proportion.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
What size should an Instagram feed post be?
The recommended square feed size is 1080 by 1080 pixels (a 1:1 ratio). This tool outputs that exact dimension, so the post displays sharply without Instagram down-scaling or recompressing it.
