Online Image Resizer

We take your privacy very seriously. All image processing is done in your browser. Your photo files never leave your computer, and we never store any of your image files on our servers.

Yes, our core features are completely free, and you can use them to resize images without any limits.

Our tool uses the Pica professional-grade scaling algorithm, which preserves maximum image detail and avoids the blurriness and jagged edges common with standard resizing, ensuring the best possible quality.

We currently support the three most common image formats: JPG, PNG, and WEBP. Uploading other formats (like HEIC, RAW) may result in processing failure.

To ensure processing speed and browser performance, we recommend uploading images smaller than 10MB. Very large files may cause the browser to slow down or fail.

To resize an image without distortion, you need to maintain its original aspect ratio. Our tool makes this easy: simply click the lock icon 🔒 between the width and height fields. When the aspect ratio is locked, changing one dimension (e.g., width) will automatically update the other to keep the proportions correct, ensuring your image resizes perfectly without being stretched.
