How to use this tool
Select your images, optionally reduce their width, choose a format and set export quality.
Example and calculation details
For example, reduce a 4000-pixel photo to 1200 pixels for an article. JPEG uses a white background for transparency.
Limits and assumptions
Maximum 20 images, 20 MB each and 40 megapixels per image. Quality controls affect JPEG and WebP; PNG is lossless. A converted file is not always smaller. Animated images and metadata may not be preserved.
Privacy
Your files and QR contents are processed in your browser. PDF and QR pages load software libraries from external CDNs; those requests reveal ordinary connection information, but the tool does not upload your selected files or text.
