Frequently Asked Questions
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most devices can handle images up to 50MB or more without issues.
Will resizing reduce image quality?
Resizing to smaller dimensions maintains quality well. Enlarging images can reduce quality since the tool must create new pixels. For best results, start with a high-resolution original.
Can I resize multiple images at once?
Currently, this tool processes one image at a time. For batch processing, you can repeat the process for each image.
Are my images uploaded to a server?
No. All processing happens locally in your browser using JavaScript and HTML5 Canvas. Your images never leave your device, ensuring complete privacy.
