Frequently Asked Questions
Got questions? We've got answers.
Yes, our Image Resizer is completely free to use. There are no subscriptions, no premium tiers, and no hidden fees. You can resize unlimited images without ever creating an account.
Yes! All image resizing happens locally in your browser using the HTML5 Canvas API. Your images are never uploaded to any server, which means the tool works offline once the page is loaded and your data stays completely private.
You can upload JPG, JPEG, PNG, WEBP, GIF, and BMP images. The resized output can be saved as JPEG, PNG, or WebP format. We recommend WebP for the best balance of quality and file size.
Resizing to smaller dimensions generally maintains high quality. For best results, keep the quality slider at 90% or above. Enlarging images beyond their original size may result in some pixelation.
There is no file size limit since all processing happens locally in your browser. However, very large images (50MB+) may take longer to process depending on your device's performance.
Currently, the tool resizes one image at a time for the best quality control. Batch resizing is coming soon. For now, you can resize images as fast as you can upload them.
Absolutely! The tool is fully responsive and works on iOS, Android, and any device with a modern web browser. You can resize images directly from your camera roll.
For web use, we recommend 80-90% quality for photos and 95-100% for graphics with text. For print or archival purposes, use 95-100%. The preview shows the exact output for each setting.
