    What makes it different

    About this tool

    Use this to remove dark scanner edges or unwanted margins. Drag the rectangle over the preview of the first page to choose what to keep, and the same proportions are applied to every page. You can also type percentages into the boxes. The cut-off part is only hidden and stays inside the file, so if something must be concealed, use the cover tool in Edit PDF instead.

    Your files are never uploaded

    Most converter sites upload your files to their servers to process them. This tool does the conversion inside your browser, so the files never leave your device. With no server involved, there is no upload to wait for and no size or file-count limit set by the site.

    Free, with no limits

    No sign-up and no payment. There is no cap on file size or number of files.

    Korean HWP documents too

    Convert HWP and HWPX, as well as Word, Excel and PowerPoint documents, to PDF.

    Drop a file, it works out the rest

    The format is detected automatically and you only see the formats it can become. You can add many files at once.

    Frequently asked questions

    Are my files uploaded to a server?

    No. The conversion runs in your browser and the files stay on your device.

    Is there a file size or file count limit?

    The site sets no limit. The work is done in your device's memory, though, so very large files can fail on devices with little memory.

    Is it really free?

    Yes. There is no sign-up and no payment. Because nothing is converted on a server, the tools cost very little to run.

    Which formats are supported?

    It reads images your browser can open, including JPG, PNG, WebP, HEIC/HEIF, AVIF, GIF and BMP, and saves them as JPG, PNG or WebP. For animated GIFs, only the first frame is converted.
