Square, portrait and story sizes in one click

Processed in your browser. Nothing is uploaded. Updated on 25 Oct 2026.

Instagram accepts three shapes and crops anything else: 1080 by 1080 pixels for a square post, 1080 by 1350 for a portrait post, and 1080 by 1920 for a story or reel cover. Pick one here and the photo is scaled to those exact pixels, with Fill and crop trimming the centre when the source is a different shape. Sizing it yourself first stops the app choosing the crop for you.

Next:

  • Passport Photo Sheet Print 8 passport photos on a 4×6 sheet or 32 on A4, at exact size

How to resize a photo for Instagram

1

Choose your photo; the Instagram square preset at 1080×1080 is already selected.

2

Pick Instagram portrait for 1080×1350 or Instagram story for 1080×1920 if you are posting one of those.

3

Leave Shape on Fill and crop so Instagram receives the exact shape and does not crop it for you.

4

Press Resize, then Download, and post the saved file from your gallery.

How Resize Image for Instagram works

Resize Image changes the pixel size of JPG, PNG, WebP and iPhone HEIC photos and shows the result next to the original before you download it. Type a width or height, pick a percentage, or choose a preset, and the other side follows the photo's ratio unless you unlock it.

People use it to make a passport photo at 35×45 mm (413×531 pixels at 300 DPI) for Indian passport, visa and exam forms, to fit a picture to Instagram's square, portrait or story sizes, and to shrink a 12-megapixel phone photo down to something a website or email can handle. When a preset has a different shape from your photo, "Fill and crop" trims the centre so the output is exactly the size the form asks for.

Enlarging a small photo adds pixels but not detail, so keep enlargements under 200 percent when you can. Use Compress Image afterwards if a form also sets a file-size limit in KB, and Convert Image if you only need a different format.

The rest of the article, and all 7 questions about Resize Image, are on the Resize Image page.

Frequently asked questions

How do I resize a photo to passport size, 3.5 x 4.5 cm?

Add the photo, open Presets and choose Passport photo (India). That sets 413 by 531 pixels, which is 35 by 45 mm at 300 DPI, the size most Indian passport, visa and exam portals ask for. Keep Fill and crop selected so the output is exactly that size, then download.

Do my photos get uploaded?

No. Resizing runs in your browser on your own device. The file never leaves your computer or phone, which is why there is no waiting and why ID photos are safe to resize here.

What is the difference between Fit inside, Fill and crop, and Stretch?

Fit inside keeps the whole photo and may leave one side shorter than the preset. Fill and crop makes the output exactly the preset size by trimming the centre. Stretch forces the size without cropping, which distorts the picture, so use it only for graphics.

Can I resize an image in KB rather than pixels?

File size in KB depends on both pixels and compression. Resize first to reduce the pixels, then use Compress Image with Target size mode to hit an exact KB limit.
