About formats

WMZ is a compressed variant of the Windows Metafile (WMF) format, introduced by Microsoft with Office 2000 in 1999. A WMZ file is simply a WMF file compressed using the gzip algorithm (RFC 1952), reducing the file size for more efficient storage and embedding within Office documents, web pages, and other containers. The underlying WMF format stores vector graphics as a sequence of GDI (Graphics Device Interface) function calls — commands that draw lines, curves, polygons, text, and bitmaps — recorded in a device-independent format that can be replayed at any resolution. WMZ preserves this vector nature: when decompressed, the file produces a standard WMF that renders through the Windows GDI subsystem using the same drawing primitives as on-screen display, ensuring visual fidelity across different output devices and resolutions. WMZ files are commonly found embedded in Microsoft Office documents (Word, Excel, PowerPoint), HTML email messages generated by Outlook, and web content produced by Office's Save as Web Page feature. The format is also used for clip art and template graphics distributed with Office installations. One advantage is space efficiency: gzip compression typically reduces WMF file sizes by 60-80%, meaningful when many small graphics are embedded in a single document or web page. The format's deep integration with the Microsoft Office ecosystem is another practical strength — WMZ graphics render natively in all Office applications without additional software, and can be extracted, decompressed, and converted using tools like LibreOffice, ImageMagick, Inkscape, and standard gzip utilities.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.

Frequently Asked Questions

Why convert WMZ to PDB?

Converting WMZ to PDB lets you extract vector graphics from Office documents into standard image formats — PDB is widely recognized and easy to share.

How do I open PDB files?

Use Palm OS devices and emulators to view PDB files. This format enjoys broad software support on all major platforms.

Is my WMZ data kept private?

Privacy is built in — WMZ uploads are purged after processing, and PDB files are auto-deleted within 24 hours.

Can I convert multiple WMZ files at once?

Multiple WMZ files can be queued for conversion at the same time — each produces a separate PDB file.

Is WMZ to PDB conversion accurate?

The converter maintains image fidelity when transforming WMZ into PDB. Color data and dimensions are preserved accurately.

What quality can I expect from PDB output?

The PDB format offers Palm handheld image format — Convertio ensures optimal encoding during the conversion process.
