Frequently Asked Questions (FAQ)
Q: What's the difference between resizing by Pixels and by File Size (KB/MB)?
Resizing by Pixels (Dimensions): This changes the actual width and height of the image. It's useful when you need an image to fit into a specific space on a website, like a banner of 800x200 pixels.
Resizing by File Size (KB/MB): This reduces the amount of storage space the image takes up, without necessarily changing its dimensions drastically. This is crucial for speeding up website loading times and for uploading images to forms that have a size limit (e.g., "upload photo under 100 KB"). Our tool achieves this by adjusting the image compression quality.
Q: How do I resize a photo to 100 KB?
It's simple with our tool!
- Upload your photo.
- Select the "By File Size" resize mode.
- In the "Target Size" box, type 100.
- Make sure the unit selected is "KB".
- Click "Resize Image", and your photo will be compressed to approximately 100 KB, ready for download.
Q: What is the best image size for a website?
There's no single "best" size, but here are some general guidelines:
- Full-width hero images: 1920 pixels wide.
- Blog post / in-content images: 800-1200 pixels wide.
- Thumbnails: 150-300 pixels wide.
Most importantly, always compress your images to keep the file size low (ideally under 150-200 KB) for fast loading.
Q: Does resizing reduce the image quality?
Yes, resizing an image, especially to reduce its file size (compression), will always cause some loss in quality. However, modern compression algorithms are very good. For use on the web, this quality loss is usually unnoticeable to the human eye, but the benefit in faster loading speed is significant.
Q: Is this tool safe? Are my images stored anywhere?
This tool is 100% safe and private. All image processing happens directly in your web browser (client-side). Your images are never uploaded to our or any other server. Once you close the browser tab, the image is gone. We respect your privacy.
