Frequently asked questions
Quick answers about privacy, formats, and how SeniorTools works in your browser. Expand a question below for details.
No. SeniorTools runs conversion, compression, resizing, and editing entirely in your web browser. Your files stay on your device and are not sent to our servers for processing.
You can convert between popular raster formats including PNG, JPEG, WebP, and AVIF. Specific pairings are available from the image converter and related tool pages.
Yes. The tools on this site are free to use in your browser. We may show ads on some pages to help cover hosting costs.
JPEG does not support transparency. Transparent areas are typically filled with a solid background (often white) when exporting to JPEG. Use PNG or WebP if you need to keep transparency.
A recent version of Chrome, Firefox, Safari, or Edge works best. Tools rely on modern browser APIs such as Canvas; very old browsers may not support every feature.
No installation is required. Open the tool you need in your browser, choose your files, and download the results when processing finishes.
We cannot access your images because processing happens locally in your browser. We do not operate a file-upload pipeline for conversion or editing.
