Resize your image
Upload, set dimensions, preview and download — all client-side. Nothing leaves your device.
Tips
- • Lock aspect ratio to avoid stretched or squashed images.
- • Use WEBP for the smallest file sizes with great quality.
- • JPEG lowers file size for photos but produces larger files than PNG when not compressed heavily.
- • Everything runs locally — no data leaves your device anywhere.
Supported inputs
PNG, JPEG, WEBP, GIF, BMP, SVG and any format your browser can decode. Output formats: PNG, JPEG, WEBP.
About Image Resizer
Image Resizer is a free, client-side tool that lets you resize images to any custom width and height directly in your browser. No uploads, no servers — all processing happens locally on your device using the HTML Canvas API.
Upload an image, pick dimensions (or use a quick preset like Instagram or YouTube sizes), choose output format and quality, then download your resized file instantly.
Common Use Cases
- Resize product photos before uploading to e-commerce platforms with specific dimension requirements.
- Prepare social media images for Twitter headers, Instagram posts, Facebook covers, and YouTube thumbnails using one-click presets.
- Reduce image dimensions to decrease file size — pair WEBP format with quality controls for optimal results.
- Generate favicons at 32x32 or app icons from larger source images.
Pro Tips
- Keep aspect ratio locked when resizing to avoid distorted images.
- For photographs, JPEG at 80-92% quality gives an excellent balance between size and visual fidelity.
- Use WEBP output for the smallest file sizes — modern browsers support it ubiquitously.
- PNG preserves every pixel with lossless compression, ideal for graphics and text-heavy images.
