Lock Aspect Ratio - Why It Matters
The "lock aspect ratio" option ensures your image maintains its original proportions when resizing. Without it, you might accidentally stretch or squish your image. We recommend keeping this option ON unless you specifically need to change the aspect ratio (which will distort the image).

Frequently Asked Questions
Will resizing reduce image quality?
Reducing image size is generally fine - you may lose some sharpness on text-heavy images. Enlarging beyond original size will cause significant quality loss (pixelation).
What's the maximum size I can resize to?
We support up to 8000×8000 pixels output. However, extremely large outputs may be slow on older devices.
Can I resize multiple images at once?
Currently, the tool resizes one image at a time. For batch resizing, consider desktop apps like XnConvert (free) or IrfanView.
Why is my image distorted after resizing?
This happens when you uncheck 'Lock aspect ratio' and enter dimensions with different proportions than the original. Keep aspect ratio locked to avoid distortion.
Should I resize before or after compression?
Resize first, then compress. This way you start with the right dimensions, then compress to your target file size.
