1. Choose files
The browser grants the page access only to files you select or drop. The tool checks format, size and, when available, dimensions or page count.
2. Set the result
Controls such as quality, dimensions, background, page range or order change the requested output. An estimate is shown when the browser can calculate it reliably.
3. Process on your device
The tool uses browser APIs and carefully loaded libraries to decode and transform the data. Files are not sent to a conversion server when the local-processing notice is present.
4. Review and download
Preview the result, compare sizes and read any warnings. Download the files you want, then clear the workspace or close the tab.
FAQ
Why can a large file fail?
Browsers have finite memory, especially on mobile. Large dimensions, many PDF pages or a big batch can exceed that limit.
Why do different browsers give slightly different results?
Browser image codecs and color handling can differ. Always review important output on your target device.
Do I need to install anything?
No. A current supported browser is enough for the tools in this MVP.
