Our image resizer supports JPEG, PNG, and WebP formats. You can upload any image in these formats and download them in the same format.
Yes, absolutely! All image processing happens directly in your browser. Your images are never uploaded to our servers, ensuring 100% privacy and security.
We automatically optimize the image quality during resizing. For best results, keep the "Maintain aspect ratio" option enabled to prevent image distortion.
Since all processing happens in your browser, the file size limit depends on your device's memory. Generally, files up to 20MB should work without issues.
Basic Usage
Using our image resizer is simple: 1) Click the "Choose File" button or drag and drop your image onto the upload area. 2) Use the width and height inputs to set your desired dimensions. 3) Click the "Download" button to save your resized image.
Currently, our tool processes one image at a time to ensure the best quality and performance. For multiple images, you'll need to process them individually.
Since processing happens in your browser, the maximum file size depends on your device's memory. We recommend keeping files under 20MB for optimal performance.
Most images are processed within seconds. Processing time depends on the image size and your device's capabilities. Larger images may take slightly longer.
Yes! Once you've loaded our website, you can use it offline. All processing happens in your browser, so no internet connection is required for image resizing.
Yes, our image resizer is completely free to use. There are no hidden fees, subscriptions, or watermarks. We believe in providing accessible tools for everyone.
Image Quality
When reducing image size, some quality loss is inevitable, but our tool uses advanced algorithms to minimize this loss. When enlarging images, we maintain the best possible quality while avoiding pixelation.
PNG is best for images with text or sharp edges. JPEG is ideal for photographs. WebP offers a good balance between quality and file size for both types of images.
Blurriness usually occurs when enlarging images beyond their original size or when reducing size significantly. To maintain sharpness, try not to enlarge images more than 20% of their original size.
To optimize file size while maintaining quality: 1) Keep the aspect ratio, 2) Use appropriate dimensions for your needs, 3) Choose WebP format for best compression, and 4) Don't enlarge images beyond their original size.
Yes, our tool applies optimal compression while resizing to reduce file size without significant quality loss. The compression level is automatically adjusted based on the image content and format.
Technical Details
Our tool works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your preferred browser for the best experience.
Yes, our tool is fully responsive and works on smartphones and tablets. However, processing very large images might be slower on mobile devices due to limited resources.
Browser-based processing ensures your privacy as images never leave your device. It also provides instant results without waiting for server processing or uploads.
Yes, you can use Space/Enter to upload images, Tab to navigate controls, and Ctrl+S (Cmd+S on Mac) to save the resized image. More shortcuts are available in our documentation.
Since all processing happens in your browser, you can continue using the tool even without internet connection. Just keep the tab open and your work won't be interrupted.
Your images are processed entirely in your browser and never uploaded to any server. This means your data remains private and secure on your device throughout the entire process.
Advanced Features
Currently, we process one image at a time to ensure the best quality. For bulk processing, you'll need to resize images individually or check our upcoming premium features.
We're working on a REST API for developers. Sign up for our newsletter to be notified when it becomes available. The API will support bulk processing and automation features.
Your last used settings are automatically saved in your browser's local storage. They will be restored the next time you visit, making it easier to resize multiple images with the same parameters.
Enable the "Maintain aspect ratio" checkbox to keep original proportions. You can then adjust either width or height, and the other dimension will automatically update to maintain the aspect ratio.
Yes, you can enter exact pixel dimensions in the width and height inputs. Uncheck "Maintain aspect ratio" if you need to set width and height independently.
Yes, we support various keyboard shortcuts: Space/Enter to upload, Tab to navigate, Arrow keys to adjust dimensions, and Ctrl+S (Cmd+S on Mac) to download. Press "?" to view all shortcuts.
Troubleshooting
Check that: 1) The file is a supported format (JPEG, PNG, or WebP), 2) The file size isn't too large, 3) Your browser is up to date, 4) You have enough free memory on your device.
Try these solutions: 1) Clear your browser cache, 2) Disable ad blockers for our site, 3) Use a different browser, 4) Check if your download location is writable.
This usually happens when processing very large images with limited memory. Try: 1) Closing other tabs, 2) Reducing image size before uploading, 3) Restarting your browser.
If the preview is blank or incorrect: 1) Refresh the page, 2) Try a different browser, 3) Check if your browser supports canvas elements, 4) Update your graphics drivers.
File size might increase when: 1) Converting from lossy to lossless format, 2) Increasing dimensions significantly, 3) Using PNG for complex images. Try using JPEG or WebP for photos.
If the page becomes unresponsive: 1) Wait a few moments for large images, 2) Refresh the page, 3) Clear browser cache, 4) Try processing a smaller image first.
