Resize Image Online — Exact Pixels, Free, No Upload
Runs on your device
Resize images in your browser
Set an exact width and height in pixels, or scale to 25%, 50% or 200%, with the aspect ratio locked. Everything runs on your device; your images never leave it.
Resize images to exact pixels, free
Change an image’s size without installing anything: type the width and height in pixels, or scale it to 25%, 50% or 200%, with the aspect ratio locked so nothing is stretched. Resize one photo or up to 50 at a time, then download them. It is free, adds no watermark and runs in your browser, so your images are not uploaded.
How to resize an image
Open your images: drag JPG, PNG, WebP or AVIF files onto the page or choose them, up to 50 at a time.
Type the new width or height in pixels. With the aspect-ratio link on, the other side follows; switch it off to set both.
Or use a preset: 25%, 50% or 200% of the original size, and 100% to go back to it.
Pick PNG, JPG or WebP (and a quality for JPG or WebP), then download the image, or all of them as a ZIP.
Why resize images here
Exact pixels. Type the width and height you need and the image comes out at that size, up to 4,000 pixels on its longest side.
Proportions kept. The aspect ratio is locked when you start, so a photo is not stretched or squashed.
Private by design. Images are resized on your device, in this browser tab. They are not uploaded, stored or sent anywhere.
Free, no watermark. No sign-up, and no watermark on the image you download.
Common uses
Application and exam forms. Many forms ask for a photo or signature at set pixel sizes: type those here. If the form also has a KB limit, lower the pixels and choose JPG or WebP at a lower quality, then check the size of the file you download, because there is no file-size setting.
Profile and social images. Scale a photo to the size a profile picture or post needs, with its proportions kept.
Email and messages. A 50% or 25% copy of a large phone photo has far fewer pixels, so it is a smaller file to attach or send.
Websites and blogs. Resize an image to the width your page shows it at, and download WebP for a smaller file.
Presets and options
Exact size: width and height in pixels.
Aspect-ratio lock: on when you start; switch it off to set both sides.
Presets: 25%, 50% and 200% of the original size, and 100% to undo the resize.
Formats: PNG (lossless, keeps transparency), JPG (smaller, no transparency) or WebP, with a quality setting from 10 to 100 for JPG and WebP.
Batches: up to 50 images per selection, “Apply edits to all” and “Download all as ZIP”.
Limits
Images up to 4,000 pixels on their longest side keep their size; a bigger image is scaled down to 4,000 pixels when you open it, and no download goes past 4,000 pixels.
50 images per selection: add more in another batch.
“Apply edits to all” gives every image the same pixel size, so an image of a different shape would be stretched: resize those one at a time.
There is no file-size target: the editor doesn’t aim for a size in KB.
Cropping, rotating and filters are in the same editor: open the Image Editor for those.
Your images stay on your device
The resize runs in this browser tab: your images are read from your device, drawn at the new size and saved back to it. Nothing is uploaded and you don’t need an account. To check, open your browser’s developer tools, choose the Network tab and resize an image: no request carries it.
Frequently asked questions
Is this image resizer free?+
Yes. Resizing is free, with no account and no watermark on the image you download.
Are my images uploaded?+
No. Resizing happens in your browser, on your device, and your images are not sent anywhere. To check, open your browser’s developer tools, choose the Network tab and resize an image: no request carries it.
How do I keep the proportions?+
Leave the link between Width and Height switched on: it is on when you start. Type one side and the other follows, so the image is not stretched. Switch it off to set both sides yourself.
Can I resize many images at once?+
Yes. Add up to 50 images per selection, and more in another batch. Resize one, then use “Apply edits to all” to give every image the same width and height, and download them all as a ZIP. It copies that exact pixel size (and the image’s other edits), so use it for images of the same shape; resize the others one at a time.
What is the largest size I can resize to?+
4,000 pixels on the longest side. A bigger image is scaled down to 4,000 pixels when you open it, and a download never goes past 4,000 pixels, so 200% of a 3,000-pixel photo comes out at 4,000 pixels.
Can I resize an image to a file size, like 50 KB?+
Not directly: there is no file-size setting, and the editor doesn’t show the size of the file it makes. To get under a limit, lower the width and height, choose JPG or WebP at a lower quality, then check the size of the file you download and try again if it is still too big.
Which formats can I resize?+
JPG, PNG, WebP and AVIF images open. Download the result as PNG (lossless), JPG or WebP; for JPG and WebP you choose the quality, from 10 to 100.
