FAQ
Image resizing FAQ
Are my images uploaded?
No. The resize operation runs locally in your browser. The page does not need to upload your source images to complete the conversion.
How do I keep the original aspect ratio?
Keep the lock enabled next to the width and height fields. Changing one dimension will calculate the other from the current ratio.
What quality should I choose?
Start around 80–90 for photographs. Use a higher value when fine detail matters, and a lower value when a smaller download is more important.
Which output format is best?
JPEG is a safe choice for photos, PNG is useful for transparency, WebP is a strong web default, and AVIF can be smaller when your target browsers support it.
Can I resize multiple images at once?
Yes. Add multiple files with the picker or drag-and-drop. Each file is processed separately, and completed results can be downloaded together as a ZIP.
Can I resize GIF or BMP files?
GIF and BMP files can be decoded by supported browsers and exported as a raster image. Animated GIFs are treated as a still image, so use a dedicated animation workflow when you need to preserve motion.
