How to resize images without stretching
- Choose your images. Add a batch of supported files.
- Choose the longest side. Use a preset or enter a custom value under Image size. A landscape image uses this for its width, and a portrait image for its height.
- Choose the format and convert. The result shows its new width and height. Download each image or the batch ZIP.
For example, a 4,000 × 3,000 image becomes 1,920 × 1,440 at the 1,920-pixel setting. A 3,000 × 4,000 portrait becomes 1,440 × 1,920. This tool keeps proportions, does not crop and never enlarges smaller originals.
Dimensions alone do not guarantee a smaller file. Try a maximum file size if an upload form has a KB limit. For transparent graphics, choose PNG, WebP or AVIF.
How longest-side resizing works
Instead of typing width and height separately, you choose one number: the length of the longest side. For a landscape picture that becomes the width; for a portrait one it becomes the height. The other side is calculated to keep the original shape. A 4,000 × 3,000 photo resized to 1,920 becomes 1,920 × 1,440, and a 3,000 × 4,000 portrait becomes 1,440 × 1,920. Because one setting suits mixed orientations, you can resize a whole folder in one pass.
Presets cover 2,560, 1,920, 1,280 and 800 pixels, and Custom longest side accepts any value from 1 to 8,192. Images already smaller than your setting are left at their size, never stretched or enlarged, and nothing is cropped.
Pixels and file size are different things
Pixel dimensions describe how big an image is on screen; file size is how many bytes it takes to store. Halving both sides leaves a quarter of the pixels, so resizing is usually the most effective way to make a file smaller. It is not a guarantee, though: the format and quality setting matter too, and saving a resized photo as PNG can still produce a heavy file. When an upload form gives a limit in KB, use the image compressor, which pairs a resize with a size target.
Common sizes to choose
Around 1,920 pixels suits full-width website images and most screens. About 1,280 pixels is a good middle ground for blogs, marketplace listings and email. Around 800 pixels works for thumbnails, forum posts and strict upload limits. Social networks change their recommended sizes often, so check the platform's current guidance before batch resizing.
Exact dimensions and print size
If a form demands exact dimensions such as 600 × 600, first crop the image to the right shape (a 1:1 square in this case) with the image cropper, then resize the longest side to 600. DPI metadata is not preserved, so physical print size is set in your printing software rather than stored in the file.
Format, transparency and privacy
The resizer starts with JPG output, which suits photos. Switch to PNG, WebP or AVIF for graphics with transparency. HEIC, TIFF, AVIF and other supported inputs can be resized and converted in the same step. All processing happens in your browser: no upload, no sign-up, and a single ZIP for the batch.
Questions and answers
How do I resize an image to 1080 pixels wide?
For a landscape or square image, choose Custom longest side and enter 1080; the width becomes 1,080 and the height follows the proportions. For a portrait image the longest side is the height, so first crop it to the shape you need or calculate the matching longest side.
Will resizing make my image blurry?
Reducing size uses high-quality smoothing, so downsized images normally look sharp at their new size. The resizer never enlarges, which avoids the blur that upscaling causes. Choosing a very low JPG quality at the same time can add softness, so keep quality around 85 to 90.
Can I set an exact width and height, like 600 × 400?
The resizer sets the longest side and keeps proportions, so it will not distort the image to fit a different shape. Crop to a 3:2 ratio first with the image cropper, then resize the longest side to 600 to get 600 × 400.
Does resizing change the DPI for printing?
The DPI tag is not copied into the resized file, and pixel dimensions are what actually change. For printing, divide the pixels by the DPI you need: 1,800 pixels at 300 DPI prints about 6 inches wide. Set the print size in your printing app.
