The instinct is to \u201ccompress\u201d it like a JPEG, but PNG doesn\u2019t work that way: the format is <strong>lossless by design<\/strong>, so there\u2019s no quality dial that throws away detail the way JPEG does. The real size wins come from two very different mechanisms, and knowing which one you\u2019re using is the difference between a 5% trim and a 70% cut. This guide explains both honestly \u2014 verified against the PNG specification (W3C) and MDN \u2014 and shows exactly how to shrink a PNG on xconvert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Quick answer:<\/strong> PNG is a <strong>lossless<\/strong> format, so true lossless optimization (better DEFLATE\/zopfli, stripping metadata) only shaves a little \u2014 often single digits to ~20%. The dramatic savings (\u201c70% smaller\u201d) come from <strong>color quantization<\/strong>: reducing a 24-bit image to an indexed 256-color palette, which is technically <strong>lossy<\/strong> but usually looks identical for logos, icons, and flat-color graphics. For photographs, don\u2019t use PNG at all \u2014 convert to JPG or WebP, which are built for photos and far smaller. Use color reduction for graphics; switch formats for photos.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Jump to a section<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"#why\">Why PNG \u201ccompression\u201d is different<\/a><\/li><li><a href=\"#two-ways\">Two ways to shrink a PNG<\/a><\/li><li><a href=\"#how-much\">How much smaller can you go?<\/a><\/li><li><a href=\"#format\">When you shouldn\u2019t keep it as a PNG<\/a><\/li><li><a href=\"#tool\">Compress a PNG on xconvert<\/a><\/li><li><a href=\"#faq\">FAQ<\/a><\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why\">Why PNG \u201ccompression\u201d is different<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A JPEG has a quality slider because JPEG is a <strong>lossy<\/strong> format \u2014 turn the quality down and it discards image detail to save space. PNG has no equivalent, because the PNG format <strong>uses lossless compression<\/strong>: the W3C specification defines PNG as \u201can extensible file format for the lossless, portable, well-compressed storage of static and animated raster images.\u201d Decode a PNG and you get back exactly the pixels that went in \u2014 no generation loss, ever.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under the hood, every PNG is already compressed. Per the specification, \u201cPNG compression method 0 is deflate compression\u201d \u2014 the same DEFLATE\/zlib algorithm used in ZIP files, applied after a per-row filtering step. So when a tool offers to \u201ccompress\u201d a PNG that\u2019s already DEFLATE-compressed, it\u2019s doing one of two fundamentally different things \u2014 and only one of them is still lossless.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"two-ways\">Two ways to shrink a PNG<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Lossless optimization (zero quality change).<\/strong> This re-runs the compression smarter without altering a single pixel:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Better DEFLATE \/ zopfli.<\/strong> Tools try multiple filter strategies and compression settings and keep the smallest result \u2014 exactly what optimizers like OptiPNG and zopflipng do. The decoded image is bit-for-bit identical; you just packed it tighter.<\/li><li><strong>Stripping metadata.<\/strong> PNG stores optional <strong>ancillary chunks<\/strong> \u2014 text comments, timestamps, color-profile data, editor tags \u2014 that the W3C spec says decoders may safely ignore. Removing the ones you don\u2019t need (while keeping a needed color profile) is free size with no visual change.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The honest catch: a PNG exported by a modern editor is often <em>already<\/em> near-optimally compressed, so lossless optimization typically buys <strong>single digits up to ~20%<\/strong> \u2014 real, but rarely dramatic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Color quantization (technically lossy, usually invisible).<\/strong> This is how \u201cPNG compressors\u201d achieve their headline savings. A full-color PNG stores up to 16.7 million possible colors (24-bit truecolor). Quantization reduces the image to an <strong>indexed-color<\/strong> palette \u2014 MDN confirms PNG natively supports indexed color, where \u201ceach pixel is a <em>D<\/em>-bit value indicating an index into a color palette.\u201d Drop from millions of colors to a well-chosen 256-color (8-bit) palette and the file shrinks enormously, while staying a valid PNG with full transparency intact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is <strong>lossy<\/strong> \u2014 you\u2019re permanently reducing the color information \u2014 but for the images people most often save as PNG (logos, icons, UI screenshots, flat illustrations, diagrams) the result is usually <strong>visually identical<\/strong>, because those images never had thousands of distinct colors to begin with. The popular <a href=\"https:\/\/pngquant.org\/\">pngquant<\/a> library, which this approach is modeled on, describes itself plainly as \u201ca command-line utility and a library for <strong>lossy<\/strong> compression of PNG images,\u201d and crucially <strong>preserves full alpha transparency<\/strong> \u2014 the thing you kept PNG for in the first place.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-much\">How much smaller can you go?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It depends entirely on which mechanism applies and on the image content:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Approach<\/th><th>Quality<\/th><th>Typical savings<\/th><th>Best for<\/th><\/tr><\/thead><tbody><tr><td>Lossless optimization (zopfli, strip metadata)<\/td><td>Identical<\/td><td>~5\u201320%<\/td><td>Already-optimized exports; archival originals<\/td><\/tr><tr><td>Color quantization to \u2264256 colors<\/td><td>Lossy, usually invisible<\/td><td><strong>up to ~70%<\/strong><\/td><td>Logos, icons, screenshots, flat graphics<\/td><\/tr><tr><td>Convert to WebP \/ JPG<\/td><td>Different format<\/td><td>Often the smallest<\/td><td>Photographs (see below)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">pngquant\u2019s own documentation reports reductions \u201c<strong>often as much as 70%<\/strong>\u201d \u2014 its worked example takes a 75,628-byte PNG down to 19,996 bytes (73% smaller) \u2014 and that gain comes almost entirely from quantization, not lossless tricks. So when a converter promises a PNG \u201c70% smaller without losing quality,\u201d read it precisely: it means <em>without visible loss to the human eye<\/em>, via color reduction \u2014 not the strict bit-for-bit sense of lossless.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>One caveat worth previewing for:<\/strong> unlike JPEG, color reduction can introduce visible <strong>banding in smooth gradients<\/strong> \u2014 a sunset or a soft drop-shadow can develop stepped contours when the palette shrinks. If your PNG has gradients, check a preview (and consider dithering, which trades a slightly larger file for smoother transitions) before committing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"format\">When you shouldn\u2019t keep it as a PNG<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here\u2019s the most important honesty check: <strong>if your image is a photograph, PNG is the wrong format<\/strong>, and no amount of PNG compression will fix that. PNG\u2019s lossless storage is ideal for sharp-edged graphics and anything needing transparency, but it\u2019s expensively large for photographic content full of subtle color variation. MDN\u2019s guidance is direct \u2014 for photographs, \u201cWebP\/AVIF provide even better compression and reproduction\u201d than PNG.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So before you compress:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Logo, icon, screenshot, diagram, anything with transparency<\/strong> \u2192 keep it PNG, use color reduction.<\/li><li><strong>A photo you happened to save as PNG<\/strong> \u2192 convert it. <a href=\"https:\/\/www.xconvert.com\/blog\/convert-png-to-jpg\/\">JPG<\/a> is universally compatible and tiny for photos (no transparency); <a href=\"https:\/\/www.xconvert.com\/blog\/convert-png-to-webp\/\">WebP<\/a> is smaller still and keeps transparency.

The dramatic \u201c70% smaller\u201d results you see advertised come from <strong>color quantization<\/strong>, which is technically lossy. For logos and flat graphics that loss is usually invisible, so \u201cwithout losing quality\u201d is honest in the <em>visual<\/em> sense \u2014 just not the strict bit-for-bit one.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Why is my PNG so large?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">PNG is <strong>lossless<\/strong>, so it stores full detail with no quality trade-off \u2014 great for sharp graphics, but heavy for photographs, which have millions of subtly varying colors PNG can\u2019t compress efficiently. If a PNG is surprisingly large, it\u2019s often a <strong>photo saved in the wrong format<\/strong>: converting it to JPG or WebP will shrink it far more than any PNG compressor can.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Does compressing a PNG remove transparency?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No.<\/strong> PNG\u2019s indexed-color and truecolor-with-alpha modes both support transparency, and quality color-reduction tools (modeled on pngquant) <strong>preserve full alpha transparency<\/strong> through compression. Your transparent background stays transparent.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">What\u2019s the difference between lossless and lossy PNG compression?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Lossless<\/strong> (zopfli, OptiPNG, metadata stripping) repacks the same pixels more tightly \u2014 identical image, small savings. <strong>Lossy<\/strong> PNG compression reduces the number of colors to an indexed palette \u2014 much bigger savings, permanent color reduction, but usually no visible difference on flat-color images. Most \u201cPNG compressors\u201d are doing the lossy color-reduction kind.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Will compressing a PNG cause banding?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">It can, in <strong>smooth gradients<\/strong>. Reducing the color palette can turn a soft gradient into visible stepped bands. Enabling <strong>dithering<\/strong> scatters pixels to smooth the transition (at a slightly larger file size), and previewing the result before you save lets you catch banding on gradient-heavy images.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Should I compress a PNG or convert it to WebP\/JPG?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Convert it if it\u2019s a photograph.<\/strong> For photos, WebP and JPG are built for the job and produce much smaller files than a compressed PNG. Keep PNG (and compress it) for logos, icons, screenshots, and anything needing transparency.
