Processed on your device — nothing is uploaded
Tip: use a preset for exact dimensions, or enter your own — the tool resizes with your browser’s high-quality scaler.
About the Image Resizer
Scale images to the exact size you need: 1920×1080 thumbnails, 1080×1080 Instagram posts, custom widths for your blog — with aspect-ratio lock so nothing gets squashed.
Resizing uses your browser's high-quality canvas scaler on your own device. Choose the output format at the same time to shrink the file even further.
How to use the Image Resizer
- 1Drop your image into the box.
- 2Set the width and height (the lock icon keeps the aspect ratio) or click a preset.
- 3Press Resize and download your image.
Frequently asked questions
Does resizing keep the aspect ratio?
Yes, while the lock is on: change one dimension and the other updates automatically.
Should I upscale small images?
Avoid it. Enlarging beyond the original size adds blur — downscaling is where canvas scaling shines.
Is my image uploaded?
No. Resizing runs 100% locally in your browser.
