Converters

Format conversion is one of the most common reasons people end up on a file-tools site in the first place — a JPG needs to become a PDF for a submission form, a PNG needs to become WebP to speed up a website, a batch of scanned pages need to leave PDF format and become individual images. Converters brings together every format-conversion tool on FilesFortress in one place, regardless of which category they primarily belong to.

On the PDF side, you'll find the full set of image-to-PDF and PDF-to-image conversions: JPG, PNG, and WebP images can each be converted into a PDF document, and PDF pages can be rendered back out as JPG or PNG images. These conversions are especially useful for combining scanned pages into a single shareable document, or pulling images back out of a PDF for reuse elsewhere.

On the image side, the General Image Converter and the dedicated JPG-to-WebP, PNG-to-WebP, WebP-to-JPG, and WebP-to-PNG tools cover the format shift that matters most for web performance today — WebP typically produces meaningfully smaller files than JPG or PNG at comparable visual quality, which is why it's become the preferred format for modern websites, while JPG and PNG remain necessary for broader compatibility with older tools and systems.

Rounding out the category, the Timestamp Converter and File Size Converter handle data-format conversions rather than file-format ones — moving between Unix timestamps and readable dates, and between byte-size units. Every conversion here runs locally in your browser, so files never need to be uploaded to complete a simple format change.
