Steps to resize image for instagram
- Add the picture. It stays in this tab while you resize image for instagram.
- Confirm the frame is 1080 by 1080 pixels. Cover is selected, lock aspect is on, and do not enlarge is off.
- Run the resize. Cover center-crops to that exact frame, and the pixels are resampled with Lanczos.
- Download the picture. If the subject sits in a corner, the crop may have cut it, so look before you submit the file.
How this target is applied
The tool opens at 1080 by 1080, the feed square for Instagram. Cover center-crops to that exact frame. A wide photo loses the sides. A tall photo loses the top and bottom. Keep the subject in the centre. If you needed the portrait or the story frame, type it before you run.
You can type 1080 by 1350 for a portrait and 1080 by 1920 for a story. Those are sizes the reader enters. Do not enlarge is turned off, so a smaller original can grow, and the pixels are resampled with Lanczos. Format stays on keep.
Which Instagram frame this opens
Instagram uses more than one frame. This page opens on the feed square, 1080 by 1080, because that is the size people ask for first. The portrait size is 1080 by 1350, and the story size is 1080 by 1920. You can type either pair into the width and height. Until you do, the tool stays on the square.
Cover still center-crops after you type a new size, so a story frame cuts a square photo heavily at the sides.
What the resample will do
Do not enlarge is off, so a smaller original can grow to 1080 by 1080, or to the portrait or story size if you typed it. The pixels are resampled with Lanczos. A blow up looks softer than a shrink from a large photo.
Look at the edges after cover runs. The feed square trims a widescreen still. The story frame trims almost everything that is not already a tall portrait.

Your file never leaves your device
Your picture is processed only in this browser and is never uploaded. The work runs in a Web Worker in this tab, using WebAssembly for the heavy parts, and the result comes back as a local blob. This site does not upload the file, store it, or log its name.
To verify: load the page, turn on airplane mode, and drop the file again. It still finishes. Or open DevTools, choose Network, and watch the run: there is no upload. The architecture is described on How it works.
Frequently asked questions
Which size does the tool open on?
The tool opens at 1080 by 1080, the feed square. That is the starting frame for this Instagram page. It does not open on the portrait or the story. You change those yourself if you need them. Cover center-crops to the numbers that are in the fields when you run.
What do I type for a portrait or a story?
Type 1080 by 1350 for a portrait and 1080 by 1920 for a story. Those are sizes you enter. The page lists them so you do not have to remember the pairs. After you type them, cover center-crops to that frame. The pixels are resampled with Lanczos.
Will a wide photo fit the feed square?
Cover center-crops it to 1080 by 1080, keeping the centre and cutting the sides. The photo is not squeezed, so circles stay circles. Put the subject in the middle before you run. A smaller original can grow because do not enlarge is turned off.
Does this make every Instagram placement?
No. One run makes one frame. The feed square is ready when the page loads. The portrait at 1080 by 1350 and the story at 1080 by 1920 are sizes you type for a second and third run. Export each file separately.
Can a small picture grow to 1080?
Yes. Do not enlarge is turned off, so a smaller original can grow to the feed square, or to the portrait or story size you typed. The pixels are resampled with Lanczos. The result is softer than a photo that was already larger than the frame.
