Frequently asked questions

What is the difference between resizing and compressing?

Resizing changes the number of pixels. Compressing reduces the file size, usually by lowering quality. Doing both gives the smallest files.

Are my images uploaded to a server?

No. Everything happens inside your browser on your own device. Your images are never sent to Tech9Pros or anyone else, so the tool also works with private photos and documents.

Can I process several images at once?

Yes. Select or drop up to 30 images together. Each one gets its own download button, and you can save them all as a single ZIP file.
