Frequently Asked Questions (FAQ)
Q: What image formats are supported?
You can upload any image format supported by web browsers including JPG, PNG, WebP, GIF, and BMP. The output maintains the original format, with quality control available for JPG images.
Q: Are images uploaded to a server?
No. All image processing is performed directly in your browser, so images are never sent to our servers. Your privacy is completely protected.
Q: What's the maximum file size limit?
Processing is limited by browser memory, so we generally recommend images under 50MB. Large images may take longer to process.
Q: How does the quality setting work?
Quality settings only apply to JPG images. 100% means highest quality (larger file size), 10% means lowest quality (smaller file size). PNG uses lossless compression so quality settings don't apply.
Q: What is the maintain aspect ratio feature?
When enabled, changing either width or height automatically calculates the other value to maintain the original image's aspect ratio, preventing image distortion.
Q: Why does my image look blurry?
Enlarging images beyond their original size can cause blurriness due to pixel interpolation. This can be improved by resizing to smaller dimensions or increasing quality settings.

Frequently Asked Questions
- Does resizing reduce image quality?
- When downsizing (making smaller), quality usually remains good. When upsizing (making larger), some quality loss may occur. We use advanced algorithms to minimize quality loss.
- What's the difference between percentage and pixel resizing?
- Percentage resizing scales by a proportion (e.g., 50% makes it half the size), while pixel resizing sets exact dimensions. Both maintain aspect ratio unless specified otherwise.
- Can I resize images while maintaining aspect ratio?
- Yes! By default, the tool maintains aspect ratio to prevent distortion. You can also choose to ignore aspect ratio for specific dimension requirements.
- What file formats are supported for resizing?
- The image resizer supports JPEG, PNG, WebP, GIF, and BMP formats. The output maintains the same format as the input unless you convert it separately.
