Resize Image
Resize images online to any pixel dimensions. Keep the aspect ratio locked to avoid distortion, or unlock it for exact width and height. Uses high‑quality resampling for sharp, clear results.
How to use the resize image tool
- Upload the image you want to resize.
- Enter the target width and/or height in pixels.
- Leave “Keep aspect ratio” checked to avoid stretching.
- Click “Process Image” and download the resized file.
Frequently Asked Questions
How do I preserve the aspect ratio?
Leave the “Keep aspect ratio” checkbox ticked. Only one of the two fields is strictly required — the other is calculated automatically.
Does resizing reduce image quality?
We use high-quality resampling (Lanczos / bicubic) so results stay sharp. Downscaling preserves quality very well; upscaling is limited by the source resolution.
What is the maximum image size I can resize?
Up to your server memory limit — typically 4,000+ pixels wide works fine on shared hosting. The upload limit is 10 MB.
Can I resize animated GIFs?
Animated GIFs will be flattened to the first frame when resized.
