Common questions

Does this tool upload my image to a server?

No. Image compression and resizing happen in your browser, so your file stays on your device during normal use.

Which file formats are supported?

You can upload JPG, PNG, WebP, and PDF files, then export to one of those formats or compress PDFs.

Will compression reduce image quality?

Lower quality settings can reduce detail, which is why the preview and size comparison are shown before download.

Can I resize without changing the format?

Yes. You can keep the same format and only change dimensions if that better fits your workflow.

Is this tool free to use?

Yes. The tool is available in your browser without signup or software installation.
