Frequently Asked Questions (FAQ)

Currently, we support the most popular web image formats: JPEG (.jpg, .jpeg), PNG (.png), and WebP (.webp) for both input and output.

Your privacy and security are paramount. All image processing happens directly within your web browser (client-side). Your images are never uploaded to our servers, ensuring they remain completely private and secure on your device.

While there's no strict server-side limit (since processing is client-side), extremely large images (e.g., over 50MB or very high resolution) might strain your browser's resources and could lead to slow performance or crashes depending on your computer's memory and processing power. For best results, we recommend images under 20MB.

The amount of size reduction depends heavily on the original image, the chosen format, and the quality setting. Highly detailed JPEGs or unoptimized PNGs can often be reduced by 50-80% or even more with minimal visual difference. Experimenting with the quality slider is the best way to find the optimal balance for your specific image.

No, our tool focuses solely on reducing the file size (in kilobytes or megabytes) by optimizing the image data. The pixel dimensions (width and height) of the image remain unchanged.
