How to resize an image
- Add your files: drag them into the box above, or click "Choose files".
- Choose a new size (a percentage or exact pixels) and click "Resize images".
- Download the resized images, in the same format you uploaded. Uploaded files are deleted right away, and results after 30 minutes.
When to resize an image
Many websites, forms and apps have size rules: a profile photo of at most 1000 pixels, a product photo of exactly 1200 by 1200, an ID photo under a certain size. Photos from modern phones are often 4000 pixels wide or more, which is far more than most uses need. Resizing makes images fit these rules, load faster and take less space, while keeping them in the same format you uploaded (JPG, PNG or WEBP).
- A website or form requires a maximum width or height in pixels.
- You want smaller photos for a blog, online store or email.
- You need several images at exactly the same size, for example product photos.
How much lighter does each percentage make a photo?
We resized three 12-megapixel JPG photos, weighing between 0.85 and 1.65 MB, with the percentage buttons. At 25% they became 1000 x 750 pixels and weighed 139 to 195 KB. At 50% (2000 x 1500) they weighed 432 to 733 KB, roughly half of the original files. At 75% they were only 6% to 10% lighter than before, even though they had lost 44% of their pixels.
The reason is quality: resized JPGs are saved at quality 90 so they stay sharp, and that is often higher than the quality the phone used. If your goal is a lighter file and not just fewer pixels, choose 50% or less, or run the result through the image compressor afterwards.
Getting a square or other exact shape
With "Keep proportions" on, the image is fitted inside the box you type, so it is never cut or distorted. A 4000 x 3000 photo typed as 3000 x 3000 comes out as 3000 x 2250, not as a square.
To get a true square, untick "Keep proportions" and the photo is squeezed to exactly the width and height you typed. This tool does not crop and does not add borders, so if the picture must not look distorted, crop it to the shape you need in your phone gallery or photo editor first, then resize it here.
Tips for the best result
- Use a percentage (50% is a good start) to shrink quickly while keeping proportions.
- Use exact pixels when a site gives you a required size. Leave "Keep proportions" on to avoid stretching; the image then fits inside the size you typed.
- Turn "Keep proportions" off only when you need an exact width and height and do not mind the picture being stretched or squeezed.
- Making a small image bigger cannot add detail, so large enlargements look soft.
- The percentage buttons only make images smaller. To enlarge one, choose exact pixels and type the new size.
About these formats
JPG: The most common photo format. It uses compression to keep files small, and it opens everywhere, but it does not support transparency.
PNG: A lossless image format that keeps every pixel sharp and supports transparent backgrounds. Great for screenshots, logos and graphics.
WEBP: A modern image format from Google. It makes files much smaller than JPG or PNG, but some older apps and websites still cannot open it.
Frequently asked questions
Does resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging it beyond its original size makes it softer, because no new detail can be created.
What does "Keep proportions" do?
It keeps the width-to-height ratio of your image. If you type only a width, the height is calculated for you, and if you type both, the image fits inside that box without being stretched.
Which formats can I resize?
JPG, PNG and WEBP. The result keeps the same format as the file you uploaded.
Is there a size limit?
Files can be up to 200 MB, and the resized image can be up to 8000 pixels on each side.
Does resizing keep the photo location and camera details?
No. The resized file is saved without EXIF details such as GPS location and camera model. Phone photos are turned upright first, so the width and height you get match the way the photo looks on your screen.
Can I resize an animated WEBP?
Only as a still image: resizing keeps the first frame of the animation. To make an animated WEBP lighter without losing the movement, use the image compressor, which keeps every frame.
