Frequently asked questions

Is PDFwerk really free?

Yes. All tools work without an account and without limits. The site is funded by ads.

Are my files uploaded?

No. Processing happens entirely in your browser. Your documents are never sent to a server or stored anywhere.

Does it work on my phone?

Yes, in every current browser on phones, tablets and computers. Very large files are faster on a computer.

How much does compression shrink a PDF?

Scanned documents and image-heavy files often shrink by 50 to 90 %. Pages are re-saved as images, so text can no longer be selected afterwards.

Images to PDF

Turn JPG, PNG or WebP images into one PDF, one image per page.

    How to convert images to PDF

    1. Choose one or more images.
    2. Set the order, page size (same as image, A4 or US Letter) and margin.
    3. Click “Convert” and download the PDF.

    Perfect for phone photos of documents, receipts or ID copies that have to be sent as a PDF. Each image becomes one page, and portrait or landscape is detected automatically.

    Frequently asked questions

    Which image formats are supported?

    JPG, PNG, WebP and GIF. iPhone photos in HEIC format only open in Safari; in other browsers save them as JPG first.

    Is image quality reduced?

    No. JPG images are embedded unchanged and other formats losslessly.

    How many images can I convert?

    As many as your device can hold in memory – usually dozens of photos without trouble.
