Image Resizer
Set a new width, height or percentage and resize many photos at once.
How to use the Image Resizer
- Drop one or more images on the left, or click to choose them.
- Pick "Width & height" and type a size, or switch to "Percentage" and enter a scale.
- Open "More options" to choose how to fit both dimensions, the output format or quality.
- Download each resized image, or all of them together as a ZIP.
Examples

About this tool
Most websites, forms and marketplaces want pictures at a particular size: a 1200 px wide blog image, a 400 × 400 avatar, or simply something smaller than the 4000 px photo your phone produced. This resizer changes the pixel dimensions of your images in one go. Enter just a width or just a height and the other side follows automatically, or scale everything by a percentage.
When you set both a width and a height, you decide what happens to the shape. "Fit inside" keeps the whole picture and makes it as large as possible within the box. "Fill exactly" covers the box and trims the overflow evenly from the edges, which is ideal for uniform thumbnails. "Stretch" forces the exact size even if that distorts the image. Big reductions are done in several smooth steps, so text and fine detail stay crisp.
Tip: if you are resizing for the web, pick WebP under "Save as" and you will usually save another 25-35% on file size at the same quality.
Frequently asked questions
Are my photos uploaded anywhere?
No. Resizing is done by your own browser on your own device. The images never leave your computer or phone, so it is safe for personal and work pictures.
How do I resize without distorting the image?
Leave "Keep aspect ratio" on and set only a width or only a height. If you need an exact box, choose "Fit inside" or "Fill exactly" instead of "Stretch".
Can I make an image bigger?
Yes, but enlarging cannot add real detail, so large increases look soft. Turn on "Never enlarge small images" if you are batch-resizing and only want to shrink the big ones.
Which format should I choose?
"Same format" keeps things simple. Choose WebP for the smallest web-ready files, JPG for maximum compatibility, and PNG for graphics, screenshots or images with transparency.
Is the photo's EXIF data kept?
No. The resized file is newly encoded, so camera details and GPS location are not carried over. The picture is rotated correctly before resizing, though.
