Frequently Asked Questions — Image Resizer
How do I resize an image to specific pixel dimensions?
Upload your image, enter the target width and height in pixels in the Exact Resize Dimensions fields, and click Download. Enable Lock Aspect Ratio to automatically calculate the correct height when you enter only the width.
What does Lock Aspect Ratio do?
Locking aspect ratio ensures that when you adjust width, the height is automatically calculated to maintain the original proportions so your photo never looks stretched or squished.
Can I resize an image without losing quality?
Enlarging an image beyond its original size will always reduce sharpness since pixels must be interpolated. However, reducing an image size (downscaling) typically preserves excellent quality. ImgDrop uses Lanczos-quality resampling via the Canvas API for the sharpest possible downscaled result.
Is the image resizer free to use?
Yes, completely free. No registration, no watermarks, no daily limits. All image resizing happens locally in your browser at no cost.
Can I resize and compress at the same time?
Yes. Enter pixel dimensions in the resize fields and a target KB value in the file size field simultaneously. ImgDrop will resize to your exact pixel dimensions and then compress to fit within your KB limit in a single operation.
