Frequently Asked Questions (FAQ)
Is this image resizer tool completely free?
Yes, our online photo resizer is 100% free to use. There are no watermarks, usage limits, or hidden costs. We provide this powerful utility for free, supported by non-intrusive ads.
Are my uploaded images secure?
Absolutely. Your privacy is our number one priority. Our tool processes all images directly within your web browser. This means your photos are never uploaded to our servers. Everything happens on your own computer, guaranteeing your files remain 100% private and secure.
How do I resize an image for Instagram or YouTube?
Using our presets makes it simple. After uploading your image, just click the "Presets" dropdown and select the social media platform you need, like "Instagram Post (1:1)" or "YouTube Thumbnail". The dimensions will be set automatically.
How can I reduce an image's file size to under 100 KB?
You have two easy options. You can use the "File Size" tab to set a target size like 100 KB directly. Alternatively, for JPG or WebP images, you can lower the "Quality" slider. This is the perfect way for reducing an image size in KB while controlling the final look.
Can I resize an image in KB or MB with this tool?
Yes, our tool provides a specific File Size tab that lets you enter a target size in KB or MB. The tool will automatically adjust the image dimensions and quality to achieve a file size as close as possible to your desired target.
How do I resize an image without losing quality?
To resize without a significant loss in quality, you should only reduce the size, not enlarge it. When reducing, our tool's smart compression algorithms and adjustable quality slider help you find the perfect balance between file size and visual clarity. Using a WebP format can also provide superior compression at high quality.
What is the difference between an image resizer and an image compressor?
An image resizer changes the physical dimensions (width and height) of a picture. An image compressor reduces the file size (KB or MB) while keeping the original dimensions. Our tool does both, giving you full control to either resize or compress your images for optimal performance.
