.heic

Convert from HEIC

Apple's default photo format since iOS 11. Based on the HEVC (H.265) codec standardized by ISO/IEC 23008-12, HEIC offers up to 50% better compression than JPEG at equivalent visual quality.

.jpg

Convert from JPG

The most widely supported image format, standardized as ITU-T T.81 in 1992. JPG (also called JPEG) is compatible with virtually every device and application, and remains the universal default for photographic content.

.png

Convert from PNG

Lossless image format standardized as ISO/IEC 15948 and maintained as a W3C Recommendation. PNG supports full alpha transparency and is the preferred format for graphics, screenshots, and images requiring sharp edges.

.webp

Convert from WebP

Developed by Google and based on the VP8 video codec, WebP delivers 25–35% smaller files than JPEG at equivalent SSIM quality according to Google's comparative study. Supported by all major browsers since 2020.

.avif

Convert from AVIF

Next-generation image format based on the royalty-free AV1 video codec developed by the Alliance for Open Media (AOMedia). Netflix's 2020 research showed AVIF achieves 50% better compression than JPEG at equivalent perceptual quality.

.tiff

Convert from TIFF

Professional image format originally developed by Aldus and now maintained by Adobe. TIFF supports lossless compression, 16-bit and 32-bit color depth, and is the de facto standard for prepress and archival imaging workflows.

.gif

Convert from GIF

Introduced by CompuServe in 1987 and standardized as GIF89a, this classic format supports frame-based animation and simple graphics with a palette of up to 256 colors per frame. It remains ubiquitous for short animations across the web.

.dng

Convert from DNG

Adobe's publicly documented raw image format, first released in 2004 as an open standard for camera raw data. DNG preserves all sensor data and is supported by over 50 camera manufacturers and editing tools including Lightroom, Photoshop, and Capture One.

.cr2

Convert from CR2

Canon's raw image format used by EOS DSLRs, storing unprocessed 14-bit sensor data in a TIFF-based container for maximum editing latitude.

.cr2 .jpg

.cr3

Convert from CR3

Canon's newer raw format introduced with its mirrorless EOS R and recent EOS cameras, using the CR3 container with improved compression options.
