Questions people ask before they convert
Frequently Asked Questions
Yes. Add up to 30 JPG, PNG, or WebP files and compress them in one batch. Each image is optimized independently to the target size.
The target is the maximum output size for each image, measured in kilobytes (KB). The browser adjusts quality and, when needed, dimensions to stay within that limit.
You can upload JPG, PNG, and WebP images up to 25 MB each. Compressed downloads are available as JPG or WebP.
Some quality reduction is required to make a file smaller. The tool starts by adjusting encoding quality and only reduces dimensions when the requested target is especially small.
No. Compression runs locally in your browser. Your original images are not uploaded to TolMaker or stored on our servers.
The tool aims to stay at or below your target size. Encoded file sizes vary by image content, so the result may be slightly smaller than the limit.
JPG is usually the smallest choice for photographs. WebP can offer a strong quality-to-size balance in modern browsers and apps.
The current output options are JPG and WebP. JPG does not support transparency, so transparent PNG files should be exported as WebP when transparency matters.
