Converting images to PDF is essential when submitting documents to portals that only accept PDF format, combining multiple scanned pages into one document, or creating a professional-looking document from photographs. This guide covers the process and best practices.
Common Scenarios
Government portals often require documents in PDF format only — even if you scanned them as JPEG images. College applications may need all mark sheets combined into a single PDF. Legal offices prefer receiving documents as PDFs rather than image files. WhatsApp compresses images when sharing, but PDFs maintain original quality.
Converting Images to PDF
Open the Image to PDF tool. Upload one or more images — JPEG, PNG, or WebP are supported. Arrange them in the order you want. Choose your page size (A4 is standard for documents, Letter for US-format, or custom dimensions). Click Convert and download your PDF.
Page Layout Options
For scanned documents, use "Fit to Page" to ensure each image fills the entire page without white borders. For photos, "Center on Page" adds a white margin around each image. If you are combining many small images (like screenshots), "Multiple per Page" lets you fit 2, 4, or 6 images on each page.
Quality and File Size
The output PDF quality depends on your source image quality. For documents, scan at 200-300 DPI for the best balance of quality and file size. The tool preserves the original image resolution — it does not upscale or downscale unless you choose to. If the resulting PDF is too large, use the Compress PDF tool afterward.
Creating Multi-Page Document PDFs
When scanning a multi-page document like a mark sheet or agreement, scan each page as a separate image, upload all images to the Image to PDF tool, arrange them in order (page 1 first), and convert. The result is a single professional PDF with each scanned page as a separate PDF page.
