Resolution has to be judged at the size the image will actually print. Color behaves differently on paper and on screens. Full-bleed images change the PDF dimensions, and eBook images need to remain clear without becoming unnecessarily heavy.<\/p>\n<p>Use this guide with the <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-paperback-formatting\/\">KDP paperback formatting guide<\/a>, <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-ebook-formatting\/\">eBook formatting guide<\/a>, and <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-bleed-safe-zones\/\">bleed and safe-zone guide<\/a> so image decisions are made as part of the whole production workflow. Review the print PDF and Kindle preview separately because the same source image can behave differently in each format.<\/p>\n<h2 id=\"resolution-judge-dpi-at-the-final-printed-size\">Resolution: Judge DPI at the Final Printed Size<\/h2>\n<p>KDP recommends print images at a minimum resolution of 300 DPI. The important phrase is <strong>at the size the image will actually print<\/strong>. A 1200 \u00d7 1800 pixel image printed at 4 \u00d7 6 inches is 300 DPI. Stretch that same image to 8 \u00d7 12 inches and the effective resolution falls to 150 DPI, even if the file metadata still claims 300.<\/p>\n<p>KDP describes images below 200 DPI as low resolution. Do not \u201cfix\u201d a small image by typing 300 into the resolution box or upscaling it without adding real detail. The pixel count has not magically improved. Where possible, return to the original photograph, illustration, chart, or scan and export a genuinely larger source.<\/p>\n<p>For print submissions, KDP also recommends inserting images at their original size, flattening transparency, and embedding images in the native file before export. The maximum print-manuscript upload size is currently 650 MB, so very high-resolution images still need sensible optimization.<\/p>\n<h2 id=\"color-for-print-choose-the-ink-option-first\">Color for Print: Choose the Ink Option First<\/h2>\n<p>Do not start with the assumption that every print image must be converted the same way. First decide whether the edition is black ink, standard color, or premium color. KDP prints color photographs in color only when you choose a color-ink option; black-and-white editions will reproduce them in black and white. Standard color is available for paperbacks, while hardcover color uses premium color.<\/p>\n<p>KDP\u2019s print guidance recommends avoiding mixed color spaces in the same file because they can produce unexpected results. Its cover guidance recommends CMYK for print cover images and warns that spot colors are not compatible with the print-on-demand workflow. For interior images, follow the specifications for the workflow and software you are using, keep the file internally consistent, and inspect the physical proof if color accuracy matters.<\/p>\n<aside class=\"vg-alert vg-alert-amber\">\n<div class=\"vg-kicker\">Screen color is not a contract<\/div>\n<p><strong>Expect some difference between a backlit monitor and printed ink.<\/strong> A proof copy is the right place to judge whether the shift is acceptable.<\/p>\n<\/aside>\n<h2 id=\"color-for-kindle-use-srgb-not-cmyk\">Color for Kindle: Use sRGB, Not CMYK<\/h2>\n<p>Kindle is a screen environment. Amazon\u2019s current reflowable-image guidance says to use an sRGB color profile and notes that Kindle does not support CMYK as the intended eBook color space. CMYK images can be converted automatically, but that is an unnecessary place to introduce color changes. Keep the eBook image source in sRGB and preview it across different device classes.<\/p>\n<p>Use color when it adds information or meaning. Some Kindle devices display in grayscale, so charts and diagrams should not rely on color alone to distinguish important categories. Labels, patterns, shapes, or direct annotations make the content more robust and more accessible.<\/p>\n<h2 id=\"placement-bleed-and-safe-areas-in-print\">Placement, Bleed, and Safe Areas in Print<\/h2>\n<p>An image that stops inside the page margins is straightforward: keep it inside the safe reading area and make sure captions remain attached to the correct image. If an image is intended to run to the edge of the paper, the interior must be set up for bleed. KDP requires bleed artwork to extend 0.125 inch beyond the top, bottom, and outside trim edges, and the manuscript must be uploaded as a PDF.<\/p>\n<p>Do not create a two-page spread as one PDF page. KDP requires single pages, even when the design visually spans a spread. Pay special attention to the gutter: faces, labels, map keys, and important details should not disappear into the binding. The <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-bleed-safe-zones\/\">KDP bleed and safe-zone guide<\/a> gives the current page-size and margin calculations.<\/p>\n<h2 id=\"ebook-images-optimize-for-clarity-not-an-arbitrary-dpi-number\">eBook Images: Optimize for Clarity, Not an Arbitrary DPI Number<\/h2>\n<p>For reflowable eBooks, pixel dimensions and display behavior matter more than assigning a print-style DPI number. Supply images large enough to remain sharp on modern screens, but do not carry enormous print masters into the eBook when a smaller optimized asset gives the same visible result. Amazon may process and convert images during publication, so quality should be checked in the converted book.<\/p>\n<p>Photographs are usually best as JPEG; flat graphics, diagrams, and illustrations can benefit from PNG depending on the artwork. Kindle supports structured HTML and CSS around images, so keep captions as real text when possible instead of baking them into the bitmap. This also improves resizing and accessibility.<\/p>\n<h2 id=\"accessibility-every-informative-image-needs-a-text-alternative\">Accessibility: Every Informative Image Needs a Text Alternative<\/h2>\n<p>Amazon\u2019s Kindle guidance requires alternative text for images in reflowable eBooks. Informative images should have concise alt text that communicates the relevant meaning; purely decorative images can use an empty alt attribute or presentation role so assistive technology can ignore them. If a chart carries an argument, the text surrounding the chart should also explain the conclusion rather than forcing the image to do all the work.<\/p>\n<p>Avoid rendering ordinary paragraphs or headings as images. Readers then lose text resizing, selection, search, pronunciation support, and screen-reader access. If the typography is part of an illustration, keep the amount of essential text inside the image as low as the design allows.<\/p>\n<h2 id=\"black-and-white-vs-color-make-the-decision-economically\">Black-and-White vs Color: Make the Decision Economically<\/h2>\n<p>Color interiors cost more to manufacture, so the decision should begin with reader value. If color is essential to interpret photographs, art, diagrams, or instructional steps, choose a color edition and price around the current printing cost. If color is decorative rather than functional, a well-prepared grayscale edition can be much more economical.<\/p>\n<p>Do the conversion intentionally. A bright color chart can collapse into several nearly identical gray tones when printed in black and white. Test grayscale versions of charts and photographs before upload, and use the current <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-print-royalties\/\">KDP print royalties and cost guide<\/a> to understand how the chosen ink option affects the economics.<\/p>\n<h2 id=\"final-image-qa-before-publication\">Final Image QA Before Publication<\/h2>\n<p>Keep an image inventory while you work. Record the image filename, source or license, intended printed size, whether it needs bleed, whether it carries essential information, and where it appears in the book. That simple production sheet prevents a common late-stage problem: discovering that the same low-resolution asset has been reused in several chapters or that a licensed image was replaced without updating the credit line.<\/p>\n<p>Audit every image in the exported files. For print, confirm effective resolution, image position, bleed, captions, transparency, and the correct ink choice. Run the PDF through Print Previewer, then use a <a href=\"https:\/\/www.vappingo.com\/word-blog\/kdp-proof-copies\/\">physical proof copy<\/a> for books where photographs, color, or fine diagrams are central to the reader experience.<\/p>\n<p>Also inspect the relationship between images and text. A figure should appear near the paragraph that introduces it, captions should use consistent punctuation and numbering, and cross-references such as \u201csee Figure 4.2\u201d should still point to the right figure after editing. If images are numbered, run a final sequential check so a deleted figure does not leave Figure 7 followed by Figure 9.<\/p>\n<p>For eBooks, test the converted file in Kindle Previewer at different screen sizes and font settings. Check that images do not become tiny, captions stay with the correct figure, alt text is present, and diagrams remain understandable on a phone. Image QA is complete only when the reader can use the information, not when the source file merely passes upload.<\/p>\n<h2 id=\"frequently-asked-questions\">Frequently Asked Questions<\/h2>\n<div class=\"vg-faq-list\">\n<details class=\"vg-faq\">\n<summary>Does KDP require 300 DPI for print images?<\/summary>\n<div class=\"vg-faq-answer\">\n<p>KDP recommends a minimum of 300 DPI for print images and describes images below 200 DPI as low resolution.
