Resize Image in Pixels

Type the width and height in pixels and get exactly that. Keep the image's own shape, pick a ratio, or crop to fill — nothing is stretched unless you ask for it. Everything runs in your browser — nothing is uploaded. Need a smaller file instead? Compress or convert.

How to resize an image

Resizing changes the pixel dimensions of an image — making it fit a specific width, a percentage of the original, or a platform's required size. Smaller dimensions also mean a smaller file, which is why resizing is one of the most effective ways to speed up a page.

Add your images, or drop them in.
Choose By dimensions for an exact width and height, By percentage to scale, or a Preset for common social and screen sizes.
Click Resize, then download each file or grab them all as a ZIP.

▢

Exact or proportional

Set precise pixels with aspect-ratio lock, scale by percentage, or pick a preset. Whatever the target needs.

⚡

Batch, instantly

Resize a whole folder at once to the same dimensions. No upload wait, no queue, no file limit.

🔒

Nothing is uploaded

Your images are resized by your own browser and never sent to a server, so they stay completely private.

Will resizing reduce quality?

Making an image smaller is safe — you are discarding pixels you no longer need, and the result looks clean. Making an image larger than its original is where quality suffers, because the browser has to invent pixels that were never there, which looks soft or blocky.

As a rule: resize down freely, but avoid scaling up much beyond the original dimensions. If you need a smaller file rather than smaller dimensions, use the compressor instead.

Pixels are what screens care about

A pixel is one dot of colour. Screens, websites, social networks and upload forms all measure images in pixels, so when a form says "maximum 1200 pixels wide", this is the right tool — not a centimetre or inch setting.

Type one number to keep the shape. With Aspect ratio set to Original, enter just the width and the height follows.

Type both for an exact size. Choose Free, enter both numbers, and the image is cropped to fill that box — drag the preview to choose which part stays.

Common sizes have their own pages: 1920×1080, 1080×1080, 500×500 and many more. For print sizes in inches, use resize in inches.

Frequently asked questions

How do I resize an image to an exact number of pixels?

Set Aspect ratio to Free, type the width and the height, and click Resize. If the photo is a different shape, it is cropped to fill — use the preview to choose what stays.

What is the difference between resizing and compressing?

Resizing changes the dimensions (the width and height in pixels). Compressing keeps the dimensions but reduces the file size by lowering quality. Resizing down does both at once, which is why it is so effective. For file size alone, use the compressor.

Will the aspect ratio be kept?

In dimensions mode, tick "Keep aspect ratio" and set just the width or height — the other is calculated automatically so the image is not stretched. Untick it to force exact dimensions, which may distort the image.

Can I resize many images at once?

Yes. Drop in as many as you like and they are all resized to the same setting in one go, then you can download them together as a ZIP. There is no limit on how many.

Are my images uploaded?

No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.

Which format will I get back?

Images keep their original format where the browser supports it (JPG, PNG, WebP). Formats a browser cannot write, like GIF or BMP, come back as PNG. To change format on purpose, use the converter.
