FAQ
Q: Will resizing reduce image quality?
A: When reducing dimensions, some detail is lost due to fewer pixels. However, our tool uses high-quality algorithms to minimize quality loss. Enlarging images may cause pixelation.
Q: Can I resize images without losing aspect ratio?
A: Yes! The aspect ratio lock is enabled by default. You can unlock it if you need to stretch or compress the image to specific dimensions.
Q: What’s the maximum image size I can process?
A: There’s no strict limit. Processing happens in your browser, so it depends on your device’s memory. Most images up to 50MB process smoothly.
Q: Can I resize multiple images to different sizes?
A: Currently, batch processing applies the same dimensions to all images. For different sizes, process images in separate batches.
Q: Is my data safe?
A: All processing happens locally in your browser. Your images are never uploaded to any server. Close the tab, and all data is gone.
