Which image format should you choose?
WebP often provides a useful balance of image quality and smaller file size for websites. JPG is widely supported and works well for photographs. PNG supports lossless images and transparency, making it useful for logos, screenshots and graphics. The best format depends on the image and where you plan to use it.
Frequently asked questions
Are my images uploaded to a server?
No. The image is processed locally in your browser and is not sent to ToolMitra's server.
Will compression always reduce file size?
No. Results depend on the original image, output format, dimensions and quality setting. PNG files or already optimized images may not become smaller. Check the before-and-after sizes before using the result.
Does resizing reduce image quality?
Reducing dimensions removes image detail, while enlarging an image cannot restore detail that was not in the original. Keep the aspect ratio enabled unless you intentionally want to stretch or crop the image elsewhere.
