The resized file saves to your device \u2014 everything runs locally in your browser.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resize vs. Crop \u2014 What&#8217;s the Difference?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Resizing<\/strong>&nbsp;scales the entire image \u2014 all content stays, pixel dimensions change. A 4000px photo resized to 1000px still shows everything, just smaller.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cropping<\/strong>&nbsp;cuts away parts \u2014 you keep a smaller area at full resolution. A 4000px photo cropped to 1000px shows only the selected region.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Usually you crop first (tighten composition), then resize (fit the target dimensions).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Does resizing reduce quality?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Downsizing (making smaller) is generally fine \u2014 you&#8217;re condensing more pixels into fewer, which can even look sharper. Upsizing (making larger) will look blurry or pixelated because you&#8217;re inventing pixels that weren&#8217;t there. Try to avoid scaling up more than 150%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I calculate pixels for print?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Multiply inches by DPI. For example, a 4\u00d76 inch print at 300 DPI needs 1200 \u00d7 1800 pixels. At 150 DPI (acceptable for large posters viewed from a distance), it only needs 600 \u00d7 900 pixels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u8868\u683c<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Print Size<\/th><th>300 DPI<\/th><th>150 DPI<\/th><\/tr><\/thead><tbody><tr><td>4\u00d76&#8243;<\/td><td>1200 \u00d7 1800<\/td><td>600 \u00d7 900<\/td><\/tr><tr><td>5\u00d77&#8243;<\/td><td>1500 \u00d7 2100<\/td><td>750 \u00d7 1050<\/td><\/tr><tr><td>8\u00d710&#8243;<\/td><td>2400 \u00d7 3000<\/td><td>1200 \u00d7 1500<\/td><\/tr><tr><td>11\u00d714&#8243;<\/td><td>3300 \u00d7 4200<\/td><td>1650 \u00d7 2100<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Can I resize multiple images at once?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Currently one at a time. For batch resizing, run each image through \u2014 it&#8217;s fast enough for most needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Will the file size change when I resize?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes \u2014 smaller dimensions mean fewer pixels, which usually means a smaller file. A 4000px photo resized to 1000px can be 80\u201390% smaller in file size.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is there a file size limit?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No hard limit. Very large images (50 MB+) may take a moment but will process fine in your browser.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>More image tools from ImgNeo:<\/strong>&nbsp;<a href=\"https:\/\/imgneo.com\/compress.html\" target=\"_blank\" rel=\"noreferrer noopener\">Compress Images<\/a>&nbsp;\u00b7&nbsp;<a href=\"https:\/\/imgneo.com\/crop.html\" target=\"_blank\" rel=\"noreferrer noopener\">Crop Images<\/a>&nbsp;\u00b7&nbsp;<a href=\"https:\/\/imgneo.com\/convert.html\" target=\"_blank\" rel=\"noreferrer noopener\">Convert Formats<\/a>&nbsp;\u00b7&nbsp;<a href=\"https:\/\/imgneo.com\/rotate-flip.html\" target=\"_blank\" rel=\"noreferrer noopener\">Rotate &amp; Flip<\/a>&nbsp;\u00b7&nbsp;<a href=\"https:\/\/imgneo.com\/remove-bg.html\" target=\"_blank\" rel=\"noreferrer noopener\">Remove Background<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Need to make an image bigger or sma&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-66","post","type-post","status-publish","format-standard","hentry","category-en"],"_links":{"self":[{"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/posts\/66","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/comments?post=66"}],"version-history":[{"count":1,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/posts\/66\/revisions"}],"predecessor-version":[{"id":71,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/posts\/66\/revisions\/71"}],"wp:attachment":[{"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/media?parent=66"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/categories?post=66"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/imgneo.com\/blog\/wp-json\/wp\/v2\/tags?post=66"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
