Images have pixel dimensions and aspect ratios; PDF pages have their own dimensions. Conversion determines how large an image appears, whether the whole frame remains visible and how much space surrounds it.\u003C\u002Fp>\n\u003Cp>These choices affect reading and printing. Filling a page can hide content, while making an image smaller on the page may do nothing to reduce the file size.\u003C\u002Fp>\n\u003Ch2>Choose image-based pages or standard paper\u003C\u002Fh2>\n\u003Cp>One approach is to size each page to its image. Images with different proportions produce differently shaped pages. This can suit documents viewed mainly on screen, where keeping the original composition matters.\u003C\u002Fp>\n\u003Cp>The alternative is a standard paper size such as A4 or Letter. It gives the document a specified format for delivery and printing. When image and paper proportions differ, however, you must choose between empty space and cropping.\u003C\u002Fp>\n\u003Cp>\u003Ca href=\"\u002Fimage-to-pdf\u002F\">DocCrunch Image to PDF\u003C\u002Fa> offers image-based sizing, A4 and Letter. With standard paper selected, page orientation follows the image, so one PDF may still contain both landscape and portrait pages.\u003C\u002Fp>\n\u003Cp>If the recipient requires a consistent orientation, check the exported file. A shared paper size does not make every page layout identical.\u003C\u002Fp>\n\u003Ch2>Fit and fill preserve different parts of the image\u003C\u002Fh2>\n\u003Cp>When aspect ratios differ, keeping proportions, avoiding empty space and avoiding cropping usually cannot all be achieved together.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Fit\u003C\u002Fstrong> scales the image proportionally to show the whole frame within the available area. It preserves the content but may leave space above, below or beside it.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Fill\u003C\u002Fstrong> also preserves proportions, but enlarges the image to cover the available area.

To remove dark borders or excess background, use \u003Ca href=\"\u002Fimage-crop\u002F\">Image Crop\u003C\u002Fa> to choose the retained area before conversion. This gives you more control over the result.\u003C\u002Fp>\n\u003Ch2>Smaller on the page does not mean a smaller file\u003C\u002Fh2>\n\u003Cp>A high-resolution image placed on A4 paper may occupy only half the page. That changes its displayed dimensions; the PDF can still contain the original image data.\u003C\u002Fp>\n\u003Cp>Adding margins or selecting smaller paper should therefore not be treated as compression.\u003C\u002Fp>\n\u003Cp>If the file must stay below a size limit, first consider whether the source needs all its pixels. Use \u003Ca href=\"\u002Fimage-resize\u002F\">Image Resize\u003C\u002Fa> when dimensions clearly exceed the intended use, or try \u003Ca href=\"\u002Fimage-compress\u002F\">Image Compression\u003C\u002Fa> when dimensions are already suitable.\u003C\u002Fp>\n\u003Cp>Do not judge compression from thumbnails alone on pages with small text or dense lines.

Text that looks crisp in a small preview can look blurred across a full page.\u003C\u002Fp>\n\u003Cp>A clear-looking source is therefore not enough.

Conversion cannot automatically fix missed focus, glare or missing edges.\u003C\u002Fp>\n\u003Cp>Image-based page sizing also does not recover the physical dimensions of the photographed sheet. Select A4 or Letter explicitly when the delivery requirements specify it.\u003C\u002Fp>\n\u003Ch2>Text may remain an image after conversion\u003C\u002Fh2>\n\u003Cp>Image-to-PDF conversion primarily organizes pages: it places images in a document and establishes size, sequence and position.\u003C\u002Fp>\n\u003Cp>It does not automatically make pictured text searchable or selectable. DocCrunch Image to PDF currently performs no OCR. The output can look like a scanned document while its lettering remains part of an image.\u003C\u002Fp>\n\u003Cp>For editable text, use an OCR tool such as \u003Ca href=\"\u002Fimage-to-word\u002F\">Image to Word\u003C\u002Fa>. An editable document and a PDF containing a searchable text layer are different outputs; decide which one you need before choosing a tool.\u003C\u002Fp>\n\u003Ch2>Set up before export, inspect afterwards\u003C\u002Fh2>\n\u003Cp>Start by correcting source orientation and cropping. Then choose paper size, fit mode and margins. Finally, check the output file size and readability.\u003C\u002Fp>\n\u003Cp>DocCrunch can combine images into one PDF or create separate PDFs for a packaged download. One document usually suits continuous reading; separate outputs suit individual distribution.\u003C\u002Fp>\n\u003Cp>Processing happens locally in the browser, but the final check still matters. Open the downloaded PDF, verify page count and sequence, inspect all edges and read the small text. For printing, also check the print dialog’s scaling settings so the content is not unexpectedly resized again.\u003C\u002Fp>\n\u003Cp>Good page settings serve the content.
