Why convert PST to WebP?
Microsoft Outlook for Windows stores email in PST data files, which people often export to back up or move a mailbox. The image shows the content of each message in the mailbox, with its text formatting and tables kept, placed one after another beneath a “PST mailbox” heading.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert PST to WebP?
Drop your PST file above and press Convert. Our servers export the messages from the mailbox, lay out each message in turn and render the pages. The result is saved as a compact WebP image, ready to download.
Does the WebP include messages from every folder of the PST file?
Yes. The converter exports the whole mailbox, looks through every folder and subfolder, and lays out the messages it finds in the WebP.
Is the formatting of PST emails kept in the WebP?
Yes. Messages are exported in their HTML form, so headings, bold and italic text, lists and tables are rendered as they were written.
What happens when a PST file fills several WebP pages?
Each page is rendered at 144 dpi and saved as its own WebP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one WebP file.
How much smaller is the WebP from a PST file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
Is my .pst file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
