Resize an image

How to resize an image

  1. 1

    Drop an image

    JPG, PNG, WebP, AVIF or HEIC. The current width and height fill in.

  2. 2

    Set the new size

    Type a width or height. The lock keeps the aspect. Or tap 1920, 1280, 1080 or 800 for the longest side.

  3. 3

    Download

    Choose JPG, PNG, WebP or AVIF and save. Resampling happens in the browser.

An image resizer that stays in the browser

The picture is read on your device. Nothing is uploaded, and there is no account or watermark.

Resizing here means resampling the pixels, not stretching them in a page layout. The new file really is the size you asked for. Making an image larger cannot recover detail that was never there. It only spreads the pixels.

Aspect ratio and the longest side

The lock is on by default. Change the width and the height follows the original proportions. Turn the lock off when you really do want a different shape. That crops nothing. It stretches.

1920, 1280, 1080 and 800 set the longest side and scale the other side to match. A portrait stays a portrait.

Which size to export

A website hero rarely needs more than 1920 on the long side. A chat preview is fine at 1280 or 800. Keep the original if you will print or edit further, and resize a copy.

HEIC from an iPhone can be resized in the same step. The decode stays on the device.

Questions

How do I resize an image online without uploading it?

Drop it here, set the width or the longest side, and download. The pixels are resampled in the browser.

Can I keep the aspect ratio?

Yes. The lock is on unless you turn it off. The longest-side buttons keep the aspect as well.

Will a bigger size look sharper?

No. Enlarging only spreads the pixels you already have. Shrink when you want a smaller file.

What size should I use for a website?

1920 on the long side is enough for a full-width photo. 1280 or 800 is plenty for a card or a thumbnail.

Can I resize a HEIC photo?

Yes. iPhone HEIC files are decoded on the device, then resized.

Can I resize several images?

Yes. The size you set is applied to each one, and Download all saves a zip.
