How it works

Resize in three steps

1

Add your image

Drag a photo onto the box or click to browse. It loads right away — no server upload.

2

Set the size

Enter new pixel dimensions or a percentage. Keep the lock on to preserve the aspect ratio.

3

Export

Download as PNG, JPG or WebP. Resize as many images as you like, free.

Why use it

Sharp results, every time

Pixels or percentage

Type an exact width and height, or scale by percentage — the two stay in sync.

Aspect ratio lock

Keep proportions locked so nothing stretches, or unlock to resize freely.

Smooth downscaling

Large reductions use step-down scaling for crisp, artefact-free results.

100% private

Resizing happens on your device with a canvas — your image is never uploaded to any server.

Good to know

Resizing images well

Resizing changes an image’s pixel dimensions — to fit an upload limit, a layout slot or a platform’s recommended size. This tool redraws your photo at the new size locally with a canvas, so it’s fast and private.

Keep the aspect ratio

Unless you deliberately want to distort an image, keep the lock on so width and height scale together. Enter one value and the other fills in automatically.

Downscaling vs upscaling

Making an image smaller looks great — this tool halves in steps for smooth results. Making it larger than the original can’t add detail that isn’t there, so enlarge sparingly and expect some softness.

Common uses

Resize an image to exact pixels or a percentage

Resize to exact dimensions

Type a width and height in pixels. Keep the aspect ratio locked to avoid stretching, or unlock it when you need an exact box.

Shrink a photo by percentage

Pick 50% or 25% to reduce a large camera photo for email or a blog post, with the proportions preserved.

Resize many images to the same width

Drop a batch and every image is scaled to the same width, each keeping its own proportions, then downloaded as a ZIP.

Resizing and quality

Making an image smaller keeps it sharp. Making it larger cannot add detail that was not there, so enlarge only when you have to.

FAQ

Frequently asked questions

Is the image resizer free?
Yes — completely free, no account and no watermarks. Part of Mokivo.
Are my images uploaded to a server?
No. Resizing happens locally in your browser, so your image never touches a server.
Will it keep the aspect ratio?
Yes by default — enter one dimension and the other is calculated. Unlock it to resize freely.
Can I make an image bigger?
Yes, up to 400%, but enlarging can’t invent detail, so upscaled images may look soft.
What formats can I export?
PNG, JPG and WebP — or Auto to keep the original format.
