All actively-maintained iPhones support WebP today.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What\u2019s the difference between WebP and AVIF?<\/h3>\n\n\n\n<p><strong>WebP<\/strong> (Google, 2010) is mature, universally supported, and produces files 25\u201335% smaller than JPG. <strong>AVIF<\/strong> (Alliance for Open Media, 2019) uses the AV1 video codec for image compression \u2014 produces files 30\u201350% smaller than WebP at equivalent quality. AVIF\u2019s downsides: slower encoding, higher CPU on decode, slightly less universal support.<\/p>\n\n\n\n<p>For new projects in 2026: AVIF for image-heavy sites (with WebP fallback for older browsers), WebP for general use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does saving as PNG-then-WebP lose quality?<\/h3>\n\n\n\n<p>No \u2014 both are lossless when set to lossless mode. Going from PNG (lossless) to WebP (lossless) preserves every pixel. WebP\u2019s lossless mode is more efficient at compressing some pixel patterns; less efficient at others. Net result: usually 25\u201335% smaller file with identical pixels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I convert lossy JPG back to lossless PNG to \u201crecover\u201d quality?<\/h3>\n\n\n\n<p>No. Lossy compression discards data permanently. Converting a JPG to PNG produces a PNG that contains the same lossy artifacts as the original JPG. You haven\u2019t recovered anything; you\u2019ve just stopped further loss.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When should I never use JPG?<\/h3>\n\n\n\n<p>For images with transparency (logos, icons), large flat-color regions (UI screenshots, line art), or text. JPG\u2019s compression algorithm produces visible artifacts on sharp edges and high-contrast text. Use PNG (or WebP\/AVIF in lossless mode) for these.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Are EXIF tags preserved across formats?<\/h3>\n\n\n\n<p>Mostly. JPG, WebP, AVIF, and TIFF all carry EXIF (Exchangeable Image File). PNG technically supports EXIF via the eXIf chunk (since 2017) but tool support is patchy. GIF doesn\u2019t support EXIF. xconvert\u2019s converter preserves EXIF where possible, strips when the destination format doesn\u2019t support it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What about HEIC?<\/h3>\n\n\n\n<p>HEIC (High Efficiency Image Container) is Apple\u2019s variant of HEIF, using HEVC compression. Files are 30\u201350% smaller than JPG at equivalent quality. The catch: HEIC support is patchy outside Apple ecosystem \u2014 Windows requires a paid Microsoft codec, many web tools don\u2019t render it. For sharing with non-Apple users, <strong>convert HEIC to JPG or WebP<\/strong> first. xconvert has <a href=\"https:\/\/www.xconvert.com\/convert-heic-to-jpg\">HEIC to JPG<\/a> and <a href=\"https:\/\/www.xconvert.com\/convert-heic-to-png\">HEIC to PNG<\/a> converters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Try it now<\/h2>\n\n\n\n<p>Compress or convert images with the <a href=\"https:\/\/www.xconvert.com\/image-compressor\">xconvert image compressor<\/a> \u2014 pick your output format from the dropdown.
