Image Resizer

Resize images to any width, height or preset size, crop to fit, and convert the format. Batch, and nothing is uploaded.

Use this free image resizer to resize image files to any width, height or exact size, straight in your browser. Set a longest side, drive it from the width or the height, scale by a percentage, or pick a ready-made size for a link preview, an Instagram post or a YouTube thumbnail. Add as many images as you like and take them back as a ZIP.

Nothing is uploaded. Your images are read on your own device, redrawn there and handed straight back. The camera and location data in a photo does not survive the process either, so what you download carries no GPS coordinates. Need a different file type instead? Use the image converter.

1. Add your images

Drop images here or click to browse

JPG, PNG, WebP, GIF, AVIF or BMP. Nothing leaves your browser.

2. Choose the new size

Longest side

Or start from a preset

Do not enlarge. An image already smaller than the target is left at its own size, because scaling a small image up only makes it blurry.

3. Output format

Quality 85

Output quality, 10 to 100

No images added yet. Your resized files will appear here.

How to resize an image

Five steps, no account and nothing to install.

Drop your images in. One or a hundred. JPG, PNG, WebP, GIF, AVIF and BMP all work, and each row shows a thumbnail and the size it arrived at.
Choose how to size them. Longest side fits each image inside a square of that size whichever way round it is. Width or Height drives one and lets the other follow. Exact size gives you a precise box. Percent scales everything by the same proportion.
Or pick a preset. Link preview, Instagram, Square, Story, LinkedIn, YouTube, and plain web sizes from 2048px down to a 320px thumbnail.
For an exact size, choose Fill or Fit. Fill gives you exactly those pixels and crops whatever does not fit, and the nine-square grid says which part to keep. Fit keeps the whole image and shrinks it until it fits inside the box.
Press Resize, then download. Each row has its own button, and Download all zips everything.

What people resize images for

Usually because something else will not accept the picture at the size the camera made it.

Getting a photo under an upload limit

A job portal or a form that refuses anything over 2 MB usually just needs the picture at a sensible width rather than straight off the camera.

Making one photo fit every platform

The same shot as a 1200×630 link preview, a 1080×1350 Instagram post and a 1080×1920 story, each cropped from the part you choose.

Speeding up a slow page

A 4000px photo displayed in a 600px column costs your visitors the whole 4000px. Resizing to what the layout actually uses is the single biggest win on most pages.

Preparing a batch of product shots

Drop the whole folder, set one size, and every image comes back matching so the grid does not go ragged.

Stripping location data before sharing

Photos from a phone carry the coordinates they were taken at. Resizing writes a fresh image without them.

Building thumbnails for a gallery

Set a 320px longest side and a batch of full-size images becomes a set of thumbnails in one pass.

Frequently asked questions

What happens to your photo data, which size to pick, and why Fill crops.

Are my images uploaded anywhere?

No. They are read in the browser with the standard file API, redrawn on a canvas in your own tab and handed straight back. Nothing is sent to us, nothing is stored, and there is nothing on a server to delete afterwards. The page does send three counters: how many jobs were run, how many files were downloaded, and one per visit. Those are numbers only and carry nothing about your pictures.

Does it remove the location data from my photos?

Yes, and that is worth knowing either way. A photo from a phone normally carries EXIF data including the GPS coordinates it was taken at, the camera and the date. Resizing writes a completely fresh image, so none of that survives. It was checked on the real output bytes rather than assumed. If you WANT to keep that data, do not put the photo through here.

My phone photos always come out sideways in other tools. Will they here?

No. A photo taken in portrait is often stored landscape with a tag saying which way up it should be, and a tool that ignores that tag turns your photo on its side with no error anywhere. This reads the tag and draws the image the way it was taken. Tested with a file carrying a real orientation tag: a 200 by 100 stored image comes out 100 by 200, upright.

What is the difference between Fill and Fit?

They only appear for an exact size, and they answer what to do when your image is not that shape. Fill gives you exactly the pixels you asked for and crops whatever does not fit, which is what a social platform expects; the nine-square grid chooses which part to keep, so a face near the top is not cut off. Fit keeps the whole image and shrinks it until it fits inside the box, so the result is usually smaller than the box in one direction. There is no letterbox option because that would need a background colour nobody chose.

Will resizing make my image blurry?

Making an image smaller does not, and that is nearly always what people want. Making one BIGGER does, because the extra pixels have to be invented. That is why Do not enlarge is on by default: an image already smaller than your target is left at its own size rather than being blown up. Turn it off only if you genuinely want the larger file, and expect it to look soft.

What size should I use for social media?

The presets carry the current numbers, checked in September 2026 rather than remembered: a link preview is 1200×630, an Instagram feed post is now 1080×1350 because Meta prioritises 4:5 portrait over the square, a square is 1080×1080, a story or reel is 1080×1920, LinkedIn feed is 1200×1200 and a YouTube thumbnail is 3840×2160. Platforms move these, so check the current guidance if something looks wrong.

Which output format should I pick?

Keep leaves each image as whatever it arrived as, which is the safe default. WebP gives the smallest file at the same quality and every current browser reads it. JPG is the most compatible and the right answer if a system is fussy. PNG is lossless and the only one to use when the image has transparency, which is why the quality slider disappears when you choose it.

What happens to a GIF, AVIF or BMP?

They are read fine, but a browser canvas cannot write those formats back out, so with Keep selected they come back as PNG and the row says so. Choose WebP or JPG explicitly if you would rather have one of those. An animated GIF loses its animation, because only the first frame is drawn.

My file got BIGGER after resizing. Why?

Usually because a heavily compressed JPEG was re-encoded at a higher quality, or a photo was turned into a PNG, which is lossless and therefore large for photographic content. The row marks it so you can see it happened. Lower the quality slider, or choose WebP, and it will come down.

Can it make a file smaller without changing the dimensions?

Set Percent to 100 and lower the quality, or switch the format to WebP, and you get the same dimensions at a smaller size. If that is all you need, the quality slider here is doing the same job a dedicated compressor would.
