Frequently Asked Questions
What is aspect ratio and why does it matter?
Aspect ratio is the proportional relationship between width and height. Locking it prevents distortion when resizing. Unlocking allows stretching to exact dimensions.
Which format should I choose?
JPEG for photos (smaller file size, no transparency). PNG for graphics with transparency. WebP for best compression with quality, but check browser support.
How does quality setting affect file size?
Lower quality = smaller file size but more compression artifacts. 80-90% is usually a good balance. PNG quality doesn't affect file size the same way.
Will resizing reduce image quality?
Enlarging images beyond original size can cause blur. Reducing size generally maintains quality. Our tool uses high-quality scaling algorithms for best results.
What is the maximum image size I can resize?
Browser memory limits apply, but most images up to 10000x10000 pixels work fine. Very large files may be slow to process depending on your device.
Is my image uploaded to a server?
No. All processing happens locally in your browser using HTML5 Canvas. Your images never leave your device, ensuring complete privacy.
