What Is an Image Resizer?
An image resizer changes the width and height of a picture. You might need it to fit a photo into a form that has a size limit, to prepare pictures for a website, a presentation or social media, or to make a very large photo small enough to send by email. This free image resizer works on one picture or on many at once.
How to Resize an Image
- Press Choose images and select your pictures. The tool shows the current size of each one.
- Choose how to resize: by width and height in pixels, or by a percentage of the original size. You can also pick one of the common sizes.
- Press Resize images, then download each file or all of them together as a ZIP.
Pixels or Percentage?
By width and height
Type the size you need in pixels. With Keep the proportions turned on, the picture is fitted inside the width and height you type, so it never looks stretched. You can also fill in only the width or only the height and the other side is worked out for you.
By percentage
Type 50 to make a picture half as wide and half as tall, or 200 to make it twice as large. This is handy when your pictures come in different sizes and you want them all smaller by the same amount.
Why Use a Browser Based Resizer?
Many online tools upload your pictures to a server first. Here the work happens on your own device, which is a good fit for personal photos and private documents. There is no watermark, no sign-up and no waiting for an upload.
Tips for Better Results
- Making a picture smaller keeps it sharp. Making it larger cannot add detail, so a big enlargement looks soft.
- Keep your original file and resize a copy, since a small picture cannot be turned back into a large one.
- For web pages, a width between 1200 and 1920 pixels is usually enough for a full-width photo.
- To make the file even smaller after resizing, use the image compressor.
- To change the format at the same time, choose JPG, PNG or WebP in the Save as menu, or use the image converter.
Limits to Know About
- You can add up to 50 images at a time, each up to 50 MB.
- The new size can be up to 16,000 pixels on each side and 100 million pixels in total.
- Animated GIFs are resized using their first frame only.
- Camera details and location data are not copied to the new file.
- Saving as WebP depends on your browser. If it cannot save WebP, the tool tells you to choose JPG or PNG.
