Supported Formats

Joint Photographic Experts Group

The most widely used image format. Lossy DCT compression keeps file sizes small at the cost of some quality - Ideal for photographs and web images.

Portable Network Graphics

Lossless compression with full alpha-channel transparency. The standard choice for graphics, logos, UI screenshots, and anything that needs sharp edges.

Web Picture Format

Google's modern format that offers 25–35% better compression than JPG and PNG. Supports both lossy and lossless modes plus transparency. Supported by all major browsers.

AV1 Image File Format

Next-generation format derived from the AV1 video codec. Achieves up to 50% better compression than JPG with full HDR, wide color gamut, and transparency support.

High Efficiency Image Container

Apple's default photo format since iPhone 7. Based on HEVC, it delivers roughly half the file size of JPG at equivalent quality. Common when airdropping or exporting from iOS/macOS.

Graphics Interchange Format

Limited to 256 colours per frame. Supports animation and 1-bit transparency. Widely used for looping animations on the web; superseded by WebP and APNG for quality work.

Windows Device-Independent Bitmap

Uncompressed raster format native to Windows. No quality loss but very large file sizes. Mostly used in legacy software and embedded systems that require raw pixel data.

Tagged Image File Format

The professional print and archiving standard. Supports multiple compression schemes (LZW, ZIP, none), multiple pages, and high bit depths. Favored by photographers and publishers.

Windows Icon Format

Container format that bundles multiple image sizes into one file. Used for website favicons and Windows app icons. jpg.now generates ICO files with multiple embedded sizes.

Truevision TARGA

An older raster format developed for graphics cards. Still in use in game development and 3D rendering pipelines. Supports 16, 24, and 32-bit depth with optional alpha channel.

Radiance High Dynamic Range

Stores floating-point luminance values far beyond standard 8-bit range. Used in 3D rendering, panorama stitching, and IBL (image-based lighting) for CGI environments.

Netpbm Portable Bitmap Formats

Simple ASCII or binary pixel formats from the Netpbm toolkit. PPM is colour, PGM is grayscale, PBM is monochrome bitmap. Common in academic image processing pipelines.

Scalable Vector Graphics

XML-based vector format that scales to any size without pixelation. SVGZ is the gzip-compressed variant. jpg.now wraps raster images inside an SVG container for output, or rasterises SVG to JPG/PNG.

Encapsulated PostScript

A PostScript-based vector format widely used in professional print, prepress, and publishing workflows. PS is raw PostScript. Both can be rasterised and converted to JPG or PNG.

Portable Document Format

Universal document format from Adobe. jpg.now converts images to single-page PDF files, and extracts image content from PDFs back to JPG or PNG. First page is used for multi-page PDFs.

XML Paper Specification

Microsoft's PDF equivalent based on XML. Introduced with Windows Vista. Less common today but still output by some Windows print workflows and legacy enterprise software.

Enhanced Metafile Format

Windows vector metafile format used to store scalable graphics in Office documents and legacy Windows applications. Can contain a mix of vector instructions and embedded raster images.

AutoCAD Drawing Formats

Industry-standard CAD formats from Autodesk. DWG is the binary drawing format, DXF is the interchangeable ASCII exchange format, DWF is the web-optimised viewer format.

Adobe Photoshop Document

Adobe's native layered image format. PSD supports up to 30,000 × 30,000 px; PSB (Large Document) supports up to 300,000 × 300,000 px. jpg.now flattens layers when converting.

GIMP eXperimental Computing Facility

GIMP's native file format. Stores all layers, channels, guides, and paths. The name reflects its experimental origins; it remains the primary format for GIMP's non-destructive workflow.
