Frequently Asked Questions
Is this tool free to use?
Yes, our tool is completely free to use. You can resize as many images as you want without any cost.
Is my image secure when using this tool?
Yes. All image processing is done locally in your browser. Your images are never uploaded to any server.
Will resizing reduce image quality?
Some quality loss is inevitable when reducing image size. However, we use high-quality algorithms to minimize quality loss. You can also adjust quality settings for JPG and WebP formats.
Which image formats are supported?
We support most common image formats including JPG, PNG, WebP, and GIF. You can also convert between these formats during resizing.
Is there a file size limit?
Since processing is done locally, there's no strict file size limit. However, very large images may take longer to process and depend on your device's capabilities.
Can I resize multiple images at once?
Yes, you can upload multiple images and they will be processed with the same settings. Each image will be downloaded separately.
What's the difference between DPI and pixel dimensions?
DPI (dots per inch) affects print quality, while pixel dimensions determine digital display size. Changing DPI doesn't affect how the image appears on screen.
Does it work on mobile devices?
Yes, our tool is fully responsive and works on all modern mobile devices. However, processing large images might be slower on mobile.
Which format should I choose?
For photos, use JPG. For images with transparency, use PNG. WebP offers the best compression but check browser compatibility. GIF is best for simple animations.
