About image dimensions
This image resizer changes the pixel dimensions of a photo without cropping it. Resize a photo by an exact width, height, percentage or preset, and keep the aspect ratio locked to avoid distortion. Presets use exact dimensions and may stretch a differently shaped image. Enlarging a photo does not recover missing detail.
Frequently asked questions
How do I resize an image online?
Add an image, choose pixel dimensions, a percentage or a preset, then keep the aspect ratio locked if you want to preserve the original shape. Review the preview before downloading.
Can I use this as a photo resizer?
Yes. The photo resizer accepts JPG, PNG and WebP photos and lets you resize a photo by exact dimensions or percentage directly in your browser.
Can I change image size without cropping?
Yes. Custom dimensions do not crop the image. Lock the aspect ratio to prevent distortion; presets may stretch an image when its original shape differs from the preset.
Will resizing a photo improve its quality?
No. Resizing changes pixel dimensions but cannot restore detail missing from the original. Enlarging a small photo may make existing softness more visible.
Which image formats can I resize?
You can resize JPG, PNG and WebP files. Choose the output format that best fits your destination and whether you need transparency.
