Frequently Asked Questions

Find Quick Answers

Does this tool really resize images without losing quality?

Yes, it uses the Canvas API with high-quality scaling algorithms to minimize quality loss during resizing. For best results, avoid extreme size reductions (e.g., reducing a 4000px image to 100px).

What image formats are supported?

Input: JPG, PNG, GIF, WebP, BMP. Output: JPG, PNG, WebP. The tool preserves transparency for PNG and WebP formats.

Is there a file size limit?

No strict limit, but very large images (e.g., over 20MB) may slow down processing. The tool processes entirely in your browser, so performance depends on your device.

Are my images uploaded to a server?

No, all processing happens locally in your browser using JavaScript. Your images never leave your computer, ensuring complete privacy.

Can I resize multiple images at once?

Currently, the tool processes one image at a time for optimal performance and simplicity. You can resize multiple images sequentially.
