BEFORE YOU CONVERT
Choose the Right File Tool
The best tool depends on what you are trying to achieve. Start with the task rather than the file extension alone.
Need a smaller file?
Compression can reduce the size of PDFs and images. Check the result after compression to make sure text, graphics and important details remain usable.
Browse PDF Tools · Browse Image ToolsNeed a different format?
Conversion is useful when a file needs to work in another application, be easier to edit or be shared in a more widely supported format.
Explore All ToolsNeed document protection?
Security-related PDF tasks can help control access or identify a document. Always make sure you have permission to modify or remove document restrictions.

COMMON QUESTIONS
File Conversion Guide FAQs
Start with the guide that matches your task, such as
merging PDFs, compressing an image, converting Word to
PDF or protecting a document. The category pages can
help you narrow the collection further.
File formats store content differently. Fonts, page
layouts, images, transparency, document structure and
other elements can affect how content appears after
conversion. Reviewing the output is especially important
for documents that need precise formatting.
Not always. The better order depends on the task and
the desired output. For important files, keep the
original and compare the converted or compressed
version before replacing it.
