About this tool
This tool changes the size of a picture or cuts out part of it. Resizing sets new pixel dimensions or a percentage of the original. Cropping keeps a rectangle you choose and removes the rest. You can also rotate or flip the image first, pick JPG, PNG or WebP for the result, and download it.
Everything happens in your browser. The image is not uploaded anywhere. Work on one image at a time, up to 25 MB. Results are limited to 8000 x 8000 pixels and 40 megapixels, and enlarging is limited to 4 times the original size.
How to use it
- Choose an image or drop it onto the page.
- Rotate or flip it if needed. This is applied before cropping or resizing.
- On the Resize tab, enter a width and height (keep the lock on to preserve proportions), type a percentage, or tap a preset. On the Crop tab, pick an aspect ratio, then drag the box or type exact X, Y, width and height values.
- Choose JPG, PNG or WebP and, for JPG and WebP, a quality level. Check the output size and the preview.
- Download the result. Use Reset to go back to the original settings.
Frequently asked questions
- Are my images uploaded?
- No. The image is opened and processed by your browser on your own device. It is not sent to a server, and closing the page discards it.
- What is the difference between resizing and compressing?
- Resizing changes the number of pixels, so the picture gets smaller or larger on screen. Compressing keeps the pixels but stores them more efficiently, which changes file size and, for lossy formats, some detail. Making an image smaller in pixels usually reduces file size too. The quality slider here also affects file size for JPG and WebP.
- Why does enlarging make an image look blurry?
- A photo only holds a fixed number of pixels. When you enlarge it, the browser has to invent the extra pixels by blending the ones that exist, which cannot add real detail. That is why enlarging is limited to 4 times, and why starting from a larger original gives better results.
- What are common image sizes?
- Typical sizes include 1920 x 1080 for full HD screens, 1080 pixels wide for many social feeds, 800 x 600 for small web images, and 512 x 512 for app icons and favicons. Each website and platform sets its own requirements, so check the one you are uploading to.
- How does the aspect ratio lock work?
- The aspect ratio is width divided by height. With the lock on, changing one side sets the other so the picture keeps its proportions, rounded to whole pixels. Turn the lock off to enter both sides yourself, but the picture will stretch if the new ratio differs from the original.
- How do I crop a passport photo?
- Choose the Crop tab and the Passport 35x45 mm ratio (or 2x2 inch for the US size), then position the box. Requirements differ by country and can include head size, background colour and file size, so check the official specification for the document you are applying for. This tool sets the shape and pixel size only. It does not check that a photo will be accepted.
