While both are widely used, each format was designed for different purposes. One might work great for your website. Another&#8217;s better for photos. Print stuff needs something else entirely. Knowing what separates them makes choosing the right one way easier.<\/p>\n<p>PNG and JPG show up everywhere in design and web work. People reach for them constantly, but the reasons differ depending on what you&#8217;re doing. Get the differences down, and picking the format that works for your project becomes straightforward.<\/p>\n<p>Here&#8217;s what sets <a href=\"https:\/\/ahaconvert.com\/zh\/jpg-%e8%88%87-png\/\" target=\"_blank\" rel=\"noopener\">PNG \u5c0d\u6bd4 JPG<\/a> apart.

Employs lossy compression whereby some data is lost each time the image is saved. But it&#8217;s strategic about what gets removed. It targets details your eyes won&#8217;t catch, like subtle color shifts in busy photo areas.<\/p>\n<p>Since JPG tosses out information, files shrink way down compared to PNG VS JPG. That&#8217;s why cameras, phones, and websites standardized on it. Speed matters. Storage space matters. Pixel-perfect quality doesn&#8217;t. One catch: JPG kills transparency. Any clear areas in the original image are changed into solid colored backgrounds.<\/p>\n<p>Modern iPhones and Androids take photos using the HEIF format. Takes up even less space. The problem is that older apps and websites don&#8217;t recognize it. So people convert HEIF to JPG all the time before uploading anywhere.<\/p>\n<p>You can dial in how much JPG compresses. Higher settings keep more detail, but the file gets bigger. Lower settings shrink it, but you lose stuff. Here&#8217;s the thing though: every time you re-save a JPG, compression happens again. Tiny changes stack up. A phenomenon known as generation loss. This is a key part of the PNG VS JPG story. You&#8217;re not stuck with one quality level. You slide the dial yourself and control the trade-off.<\/p>\n<h2>PNG \u548c JPG\uff1a\u5b83\u5011\u6709\u4ec0\u9ebc\u5340\u5225\uff1f<\/h2>\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1100421793\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" style=\"margin:0px 0px 10px 0px;\">\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"750\" src=\"https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison.png\" class=\"attachment-large size-large\" alt=\"\u6bd4\u8f03 PNG \u548c JPG \u5728\u58d3\u7e2e\u7387\u3001\u6a94\u6848\u5927\u5c0f\u548c\u900f\u660e\u5ea6\u65b9\u9762\u7684\u5dee\u7570\" srcset=\"https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison.png 1000w, https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison-300x225.png 300w, https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison-768x576.png 768w, https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison-16x12.png 16w, https:\/\/ahaconvert.com\/wp-content\/uploads\/2026\/09\/png-vs-jpg-compression-comparison-600x450.png 600w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1100421793 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n<p>PNG VS JPG in comparison tells you what each one can do and what it can&#8217;t.

Do that with JPG and the image degrades a little more each cycle.<\/p>\n<h3>2. \u6a94\u6848\u5927\u5c0f\uff1aPNG \u8207 JPG<\/h3>\n<p>\u5728\u6bd4\u8f03 PNG \u548c JPG \u683c\u5f0f\u6642\uff0c\u6a94\u6848\u5927\u5c0f\u59cb\u7d42\u662f\u6c7a\u5b9a\u6027\u56e0\u7d20\u3002\u901a\u5e38\u60c5\u6cc1\u4e0b\uff0cJPG \u683c\u5f0f\u7684\u5f71\u50cf\u6bd4 PNG \u683c\u5f0f\u7684\u5f71\u50cf\u8981\u5c0f\uff0c\u5c24\u5176\u662f\u5728\u5f71\u50cf\u8272\u5f69\u8b8a\u5316\u8f03\u5927\u7684\u60c5\u6cc1\u4e0b\uff0c\u4f8b\u5982\u98a8\u666f\u7167\u6216\u4eba\u50cf\u3002 PNG \u5716\u50cf\u4e4b\u6240\u4ee5\u9ad4\u7a4d\u8f03\u5927\uff0c\u662f\u56e0\u70ba\u5b83\u4fdd\u6301\u5716\u50cf\u4e2d\u6bcf\u500b\u50cf\u7d20\u7684\u5927\u5c0f\u4e0d\u8b8a\uff0c\u9019\u96d6\u7136\u6709\u5229\u65bc\u6b78\u6a94\uff0c\u4f46\u537b\u4e0d\u5229\u65bc\u5132\u5b58\u548c\u8f09\u5165\u901f\u5ea6\u3002.<\/p>\n<h3>3. \u900f\u660e\u5ea6\uff1aPNG \u8207 JPG<\/h3>\n<p>PNG \u8207 JPG \u7684\u6bd4\u8f03\uff1aPNG \u5728\u900f\u660e\u5ea6\u65b9\u9762\u66f4\u52dd\u4e00\u7c4c\u3002\u5b83\u7684 Alpha \u901a\u9053\u652f\u63f4\u5b8c\u5168\u6216\u90e8\u5206\u900f\u660e\u3002 Logo \u53ef\u4ee5\u653e\u7f6e\u5728\u4efb\u4f55\u80cc\u666f\u4e4b\u4e0a\uff0c\u7121\u9700\u88ab\u6846\u4f4f\u3002 JPG \u5b8c\u5168\u4e0d\u652f\u63f4\u900f\u660e\u5ea6\u3002\u532f\u51fa\u6642\uff0c\u900f\u660e\u50cf\u7d20\u6703\u8b8a\u6210\u767d\u8272\u6216\u7d14\u8272\u3002 Logo\u3001\u5716\u793a\u3001\u7522\u54c1\u6473\u5716\uff1f\u5e7e\u4e4e\u7e3d\u662f\u9078\u64c7 PNG\u3002\u50c5\u6191\u9019\u4e00\u9ede\u5c31\u8db3\u4ee5\u8aaa\u660e\u554f\u984c\u3002.<\/p>\n<h3>4. \u5716\u5f62\u548c\u6587\u5b57\uff1aPNG \u8207 JPG<\/h3>\n<p>PNG \u683c\u5f0f\u6bd4 JPG \u683c\u5f0f\u66f4\u80fd\u6e05\u6670\u5730\u5448\u73fe\u7dda\u689d\u92b3\u5229\u3001\u8272\u5f69\u5e73\u6de1\u3001\u6587\u5b57\u6e05\u6670\u6613\u8b80\u7684\u5f71\u50cf\u3002\u9019\u662f\u56e0\u70ba\u6709\u640d\u58d3\u7e2e\u6703\u626d\u66f2\u92b3\u5229\u7684\u908a\u7de3\uff0c\u4e26\u5728\u5f71\u50cf\u4e2d\u5305\u542b\u6587\u5b57\u548c\u5e7e\u4f55\u7269\u4ef6\u6642\u7522\u751f\u58d3\u7e2e\u507d\u5f71\u3002\u56e0\u6b64\uff0c\u87a2\u5e55\u622a\u5716\u3001\u5716\u8868\u3001\u8cc7\u8a0a\u5716\u8868\u548c\u57fa\u65bc\u6587\u5b57\u7684\u8a2d\u8a08\u5728 PNG \u683c\u5f0f\u4e0b\u770b\u8d77\u4f86\u66f4\u52a0\u6e05\u6670\u92b3\u5229\u3002\u76f8\u53cd\uff0cJPG \u683c\u5f0f\u7684\u8a2d\u8a08\u521d\u8877\u662f\u7528\u65bc\u7167\u7247\uff0c\u7167\u7247\u4e2d\u67d4\u548c\u7684\u8272\u5f69\u6bd4\u92b3\u5229\u7684\u908a\u7de3\u66f4\u5bb9\u6613\u63a9\u84cb\u58d3\u7e2e\u507d\u5f71\u3002.<\/p>\n<h3>5. \u7db2\u9801\u6548\u80fd\uff1aPNG \u8207 JPG<\/h3>\n<p>\u5716\u7247\u5927\u5c0f\u76f4\u63a5\u5f71\u97ff\u7db2\u7ad9\u901f\u5ea6\u3002\u5c0d\u65bc\u5167\u5bb9\u8c50\u5bcc\u7684\u7db2\u7ad9\u4f86\u8aaa\uff0cPNG \u548c JPG \u683c\u5f0f\u7684\u5dee\u7570\u81f3\u95dc\u91cd\u8981\u3002\u8f03\u5c0f\u7684 JPG \u6a94\u6848\u8f09\u5165\u901f\u5ea6\u66f4\u5feb\uff0c\u4f54\u7528\u983b\u5bec\u66f4\u5c11\uff0c\u4e26\u4e14\u7531\u65bc\u9801\u9762\u901f\u5ea6\u81f3\u95dc\u91cd\u8981\uff0c\u56e0\u6b64\u9084\u80fd\u63d0\u5347\u641c\u5c0b\u6392\u540d\u3002 PNG \u6a94\u6848\u8f09\u5165\u901f\u5ea6\u8f03\u6162\uff0c\u56e0\u70ba\u5b83\u5011\u5305\u542b\u66f4\u591a\u8cc7\u6599\u3002 WebP \u548c AVIF \u662f\u6b63\u5728\u7e2e\u5c0f\u9019\u4e00\u5dee\u8ddd\u7684\u65b0\u578b\u683c\u5f0f\u3002\u5982\u679c\u60a8\u4f7f\u7528\u7684\u662f AVIF \u5716\u7247\uff0c\u8acb\u5c07\u5176\u8f49\u63db\u70ba PNG \u683c\u5f0f\uff0c\u4ee5\u4fdd\u6301\u8207\u820a\u7248\u8edf\u9ad4\u7684\u76f8\u5bb9\u6027\u3002\u5927\u591a\u6578\u5716\u7247\u5eab\u3001\u90e8\u843d\u683c\u6a19\u984c\u548c\u7522\u54c1\u5716\u7247\u4f7f\u7528 JPG \u683c\u5f0f\u6548\u679c\u66f4\u4f73\uff0c\u5f9e\u800c\u4fdd\u6301\u7db2\u7ad9\u5feb\u901f\u8f09\u5165\u3002.<\/p>\n<h2>PNG \u548c JPG \u54ea\u500b\u756b\u8cea\u6bd4\u8f03\u9ad8\uff1f<\/h2>\n<p><strong>\u7c21\u7b54\uff1a<\/strong> PNG \u683c\u5f0f\u4fdd\u7559\u4e86\u6240\u6709\u5f71\u50cf\u8cc7\u6599\u3002 JPG \u683c\u5f0f\u70ba\u4e86\u7e2e\u5c0f\u6a94\u6848\u5927\u5c0f\u6703\u4e1f\u68c4\u90e8\u5206\u8cc7\u6599\u3002\u56e0\u6b64\uff0cPNG \u683c\u5f0f\u5728\u5f71\u50cf\u54c1\u8cea\u4e0a\u66f4\u52dd\u4e00\u7c4c\uff0c\u4f46\u7576\u6a94\u6848\u9ad4\u7a4d\u904e\u5927\u6642\uff0c\u9019\u7a2e\u512a\u52e2\u5c31\u6703\u6d88\u5931\u3002.<\/p>\n<p>Here is where the PNG VS JPG debate gets nuanced, because &#8220;quality&#8221; depends on what you are measuring.

Cuts data to make files smaller. Technically, it is lower quality when you look pixel by pixel. However, there is one issue here: the difference won\u2019t be noticeable in most cases. Once the JPG quality settings are increased to the maximum level, pictures will be identical to PNG. Your eye doesn&#8217;t catch what JPG removes from photos anyway.<\/p>\n<p>So PNG beats JPG on raw accuracy. JPG delivers similar-looking results at way smaller file sizes, especially with photos. Which one&#8217;s actually better, PNG VS JPG? Depends on what you need\u2014perfect accuracy or small files.

JPG uses lossy compression. Some image data gets permanently removed when you save. At high quality settings, the loss is barely noticeable in photos. But text, sharp edges, and flat colors show the damage. Re-save a JPG, and you lose more quality. PNG doesn&#8217;t have that problem.<\/p>\n<h3>d. \u70ba\u4ec0\u9ebc\u8981\u5c07PNG\u8f49\u63db\u70baJPG\uff1f<\/h3>\n<p>File size. JPG files shrink way down compared to PNG, especially with photos. Your website loads faster. Storage takes up less space. Files get easier to share.
