How it works
- 1Drop the photo in. Anything larger than 1080 pixels is ideal — Instagram downscales, it never sharpens.
- 2The image is scaled to fill and cropped evenly from the center to exactly 1080 × 1080.
- 3Check where the crop landed before posting. A subject near an edge is what usually gets trimmed.
Frequently asked questions
- Why 1080 pixels and not larger?
- 1080 is the width Instagram serves feed images at, so anything wider is downscaled and re-compressed on their servers with settings you do not control. Uploading at the display width means the only resampling that happens is the one you can see here.
- Should my post be square or vertical?
- Square is the safe default and the shape the profile grid shows. Vertical 4:5 posts occupy more of a phone screen as someone scrolls, which is why many accounts prefer them — but the grid still crops those to a square, so keep the subject centred either way.
- Instagram made my photo look worse. Can this fix it?
- Partly. Instagram re-compresses every upload, and the damage is worst when it also has to resize — a 4000-pixel photo is scaled down and re-encoded in one aggressive step. Handing it an image already at 1080 pixels and reasonably compressed removes the resize from that equation, which visibly helps on detailed photos.
- What happens to a photo that is not square?
- It is scaled until it fills the square and the overflow is trimmed equally from both sides — nothing is stretched. A landscape photo loses its left and right edges, a portrait loses top and bottom. If the framing matters, crop it yourself first and then run it through here.
About this tool
Instagram serves feed images at 1080 pixels wide, and everything you upload is resized to that width on their side. Doing the resize yourself is not about beating their algorithm — it is about removing a step you have no control over. When Instagram receives a 4000-pixel photo it downscales and re-compresses in one pass tuned for their storage costs, and detailed images visibly suffer for it.
This tool scales your photo until it fills a 1080 × 1080 frame and crops the excess evenly from the centre, so proportions stay natural and nothing is stretched. Because the square is also the shape the profile grid uses, it is the framing worth optimising for even when you post vertically — a subject that sits comfortably in the centre survives every crop the platform applies.
Start from the largest original you have. Downscaling keeps an image crisp; upscaling a small photo to reach 1080 pixels only produces a soft square. The resize and compression both run in your browser, so the photo is never uploaded here, the result appears immediately, and your original file is left exactly as it was.
