Frequently Asked Questions
Can I resize without distorting the image?
Yes. Lock the aspect ratio to maintain proportions when resizing. When you change the width, the height adjusts automatically and vice versa, preventing any stretching or squishing.
What image formats are supported?
FileMuncher supports resizing JPEG, PNG, WebP, GIF, and BMP images. The output format matches your input by default.
Can I make an image larger?
Yes, you can upscale images, but be aware that enlarging an image beyond its original dimensions may reduce sharpness since no new pixel data is created. For best results, avoid scaling much beyond the original size.
Are there preset sizes available?
Yes. The tool includes presets for common dimensions including social media sizes for Instagram, Facebook, Twitter, and YouTube. You can also enter custom pixel values.
Is my image uploaded to a server?
No. All resizing happens locally in your browser. Your image never leaves your device, providing complete privacy for personal or commercial photos.
