Image Resizer
Resize JPG, PNG and WebP images to exact pixels or a percentage. Batch resize up to 20 photos without uploading them.
Your files never leave your device. Privacy
A modern phone camera takes photos around 4000 pixels wide, while a blog, a passport form or a marketplace listing usually needs something between 600 and 2000 pixels. Resizing to the size you actually need makes files smaller and uploads faster.
How to use the Image Resizer
-
Add your images
Drop up to 20 images into the box, tap to choose them, or paste a screenshot with Ctrl+V.

Features
-
Pixels or percentage
Set exact dimensions, or scale everything to a percentage such as 50 percent in one move.
-
Aspect ratio lock
With the lock on, images fit inside your width and height without being squashed or stretched.
-
Batch resizing
Resize a whole folder of product photos or holiday pictures in one go, each keeping its own shape.
-
Format conversion
Keep the original format or save the resized copies as JPG, PNG or WebP.
-
High quality scaling
The browser uses high quality smoothing, so downsized photos stay sharp instead of jagged.
-
No upload, no limits
Your photos stay on your device and there is no account, watermark or daily cap.
When to use it
Online applications
Visa, exam and job portals often ask for photos at a fixed size, for example 600 by 600 pixels.
Website and blog images
Uploading a 4000 pixel photo into a 800 pixel wide column wastes bandwidth. Resize first, then compress.
Marketplace listings
Stores and classified sites look neater when every product photo has the same dimensions.
Sharing on chat apps
Smaller pictures send faster on slow connections and use less of the other person’s data.
Resizing versus compressing
Resizing changes the number of pixels. Compressing keeps the pixels but stores them more efficiently. A 4000 by 3000 photo resized to 1600 by 1200 has about 84 percent fewer pixels, which is usually the biggest single saving you can make.
For the smallest files, resize to the size you need first, then run the result through our Image Compressor.
Will making an image bigger improve it?
Not really. Enlarging a small image spreads the same detail across more pixels, so it becomes softer. The tool allows it, which is useful when a form demands a minimum size, but it cannot add detail that was never captured.
Frequently asked questions
How do I resize an image without losing quality?
Make it smaller, not bigger, and keep the aspect ratio locked. Downsizing with high quality smoothing keeps photos sharp. Save as PNG if you need zero extra compression, or JPG at the default quality for a smaller file.
Can I resize many images at once?
Yes. Add up to 20 images and they are all resized with the same settings. Each one keeps its own aspect ratio when the lock is on.
How do I resize a photo to 600 x 600 pixels?
Type 600 in both boxes. If your photo is not square, keep the lock on to fit it inside 600 by 600, or crop it square first with our Image Cropper for an exact 600 by 600 result.
Are my photos uploaded anywhere?
No. Resizing happens inside your browser. Nothing is sent to a server, so it is safe for ID photos and private pictures.
What does resize by percentage do?
It multiplies both width and height by the same amount. At 50 percent, a 4000 by 3000 photo becomes 2000 by 1500, which has a quarter of the pixels.
Does resizing remove photo location data?
Yes. The new file is drawn fresh by your browser, so camera details and GPS location from the original are not copied across.
