About formats

PNG (Portable Network Graphics) is a lossless raster image format developed by the PNG Development Group and published as a W3C Recommendation on October 1, 1996, created as a patent-free replacement for GIF after the Unisys LZW patent controversy. PNG uses a two-stage compression pipeline: a prediction filter selects the optimal per-row preprocessing (none, sub, up, average, or Paeth), then DEFLATE compression encodes the filtered data. The format supports rich color modes — 1/2/4/8/16-bit grayscale, 8/16-bit per channel true color, and indexed color with palettes up to 256 entries — all with optional alpha transparency ranging from a single transparent color to a full per-pixel alpha channel with 256 or 65536 levels. PNG also stores gamma correction, ICC color profiles, text metadata, and suggested background color. One advantage is lossless compression with transparency — PNG preserves every pixel exactly while supporting smooth semi-transparent edges, making it the standard format for web graphics, UI elements, logos, screenshots, and any image where artifacts or color shifts are unacceptable. Universal support is another core strength: every web browser, operating system, image editor, and programming library handles PNG natively. The format has proven remarkably durable — after nearly three decades, PNG remains the default lossless web image format. While newer formats like WebP and AVIF offer better compression, PNG's combination of lossless quality, full transparency, and absolute ubiquity keeps it indispensable.

JPE is an alternate file extension for JPEG (Joint Photographic Experts Group) compressed images, functionally identical to .jpg and .jpeg files. The .jpe extension originated in early computing environments where three-character file extensions were the norm (as on MS-DOS and Windows 3.x), and some applications registered .jpe as an additional JPEG-associated extension alongside .jpg. JPE files contain standard JPEG-compressed data: the same DCT-based lossy compression that transforms 8x8 pixel blocks into frequency coefficients, quantizes them according to quality settings, and encodes the result using Huffman entropy coding. The file structure follows the JFIF or Exif specification, beginning with an SOI marker (0xFFD8), followed by application-specific markers (APP0 for JFIF, APP1 for Exif), quantization and Huffman table definitions, and the entropy-coded image data. JPE files support 8-bit grayscale and 24-bit color images at any resolution, and may contain embedded ICC color profiles, Exif metadata from digital cameras (exposure, GPS, lens data), IPTC captions, and XMP metadata. The JPEG compression algorithm achieves its remarkable efficiency by exploiting the human visual system's reduced sensitivity to high-frequency spatial detail and color differences — discarding information the eye cannot readily perceive. One advantage is the extension's broad registration in MIME type databases and file association tables, ensuring that email clients, web servers, and operating systems recognize .jpe files as JPEG images and handle them correctly. The format's universal reach is another definitive strength — JPE/JPEG is supported by literally every image-capable software and hardware device manufactured in the last three decades. Files are processable by any tool that handles JPEG, including all browsers, editors, and programming libraries.
Initial release: 1992

Frequently Asked Questions

Why convert PNG to JPE?

JPE is an alternate JPEG extension used by some systems. Converting PNG to JPE gives you compact, lossy-compressed images for broader sharing.

Is JPE identical to JPEG?

Yes — JPE, JPEG, and JPG all refer to the same image format. The extension varies by platform convention, but the data is identical.

What opens JPE files?

All web browsers, Windows Photos, macOS Preview, IrfanView, GIMP, Photoshop, and every image viewer recognize JPE as a JPEG file.

Is PNG to JPE free?

Standard conversions are free on Convertio. Premium plans provide batch processing and priority conversion speed.

What about transparency?

JPE (JPEG) does not support transparency. Any transparent areas in your PNG will be rendered with a solid background color.

Can I choose the compression level?

Yes — adjust the quality slider to control the trade-off between file size and image clarity in the output.
