About formats

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.

JPEG is one of the most widely used image formats in computing, standardized by the Joint Photographic Experts Group and published as ISO/IEC 10918-1 in September 1992. The .jpeg extension is functionally identical to .jpg — both contain the same JFIF or Exif-wrapped JPEG compressed image data. The format applies lossy compression using the discrete cosine transform (DCT): images are divided into 8x8 pixel blocks, transformed into frequency coefficients, quantized to discard visually less significant information, and entropy-coded for storage. The quality-to-size tradeoff is user-selectable, with typical settings producing files 10-20 times smaller than uncompressed originals at visually acceptable quality. JPEG supports 8-bit grayscale and 24-bit color, with Exif metadata carrying camera settings, GPS coordinates, timestamps, and thumbnails. One advantage is absolute universality — JPEG is readable by every image viewer, web browser, operating system, camera, phone, and printer manufactured in the past three decades, making it the safest format for sharing photographic images with any recipient. The efficient compression of continuous-tone photographic content is another core strength: JPEG consistently produces compact files from camera sensors and real-world scenes where subtle color gradients dominate. While newer formats like WebP and AVIF achieve better compression ratios, JPEG's installed base is so vast that it remains the default output of digital cameras and the most common image format on the web.

Frequently Asked Questions

Why convert PDB to JPEG?

PDB is an obsolete Palm format. Converting to JPEG provides compressed photos and opens your content to modern viewers.

What programs open JPEG files?

Open JPEG with any image viewer, web browser, or photo editor. On mobile devices, built-in gallery apps or third-party viewers also handle this format.

Do I need to create an account to convert?

Registration is not required. You can convert PDB to JPEG immediately — just visit the page and start uploading.

Does the converter work on mobile devices?

Yes — the PDB to JPEG converter is fully browser-based and works on phones, tablets, and desktop computers equally well.

Will image dimensions change during conversion?

No — the converter keeps the same image size. Dimensions only change if you explicitly set resize options.

Is the conversion process secure?

All files are handled securely. PDB uploads are purged after processing, and resulting JPEG files expire within 24 hours.
