Untitled: Practical Tips for Merging Images into One PDF

Start with compatible files.
Start with compatible files. We use the Untitled image-to-PDF converter with JPG, PNG, or WebP images. It accepts up to 10 files, so scans, receipt pages, and supporting photos can be combined in one pass without installing software or creating an account.
A file larger than 15 MB is blocked with a "Compress and retry" message, while unsupported formats such as HEIC, GIF, SVG, or PDF are rejected individually. The other accepted images remain in the list, which makes it easier to fix one problem without rebuilding the whole batch.
Order pages before choosing options.
Order pages before choosing options. The thumbnail order becomes the PDF's page order. On desktop, drag the reorder handles; on a phone, use long-press drag. We inspect the sequence after moving anything, especially when the PDF contains several pages.
A common mistake is uploading files in one order and assuming the PDF will sort them automatically. It does not: the initial list follows upload order. For an official submission, match the sequence to the document's intended order before exporting.
Choose page size and orientation deliberately.
Choose page size and orientation deliberately. A4 is the default, with Letter and Fit to image also available. Orientation can remain on Auto or be fixed to Portrait or Landscape. For a mixed batch, Auto saves a decision; for a consistent set of pages, a fixed orientation can make the result easier to scan.
Fit to image is useful when preserving each source image's dimensions is the priority, but it can create pages with different sizes. When a receiving system expects a uniform document, we choose A4 or Letter instead. A convenient default is not a substitute for checking the portal's stated requirements.
Set margins for readability.
Set margins for readability. Small is the default, and the available choices are None, Small, and Medium. We leave some margin around text that will be printed or viewed on a small screen, while None can suit a screenshot with intentional edge-to-edge content. Removing a margin does not improve the source image's resolution.
For receipts or stamps close to an edge, check the first-page thumbnail after generation. The status line also shows the page count and total size, helping us catch an unexpected rotation, a margin mistake, or a blurry source image before sharing the PDF.
Export locally, then verify the result.
Export locally, then verify the result. After the settings are ready, use the sticky download button. The output is named images-YYYYMMDD.pdf, and the interface labels the workflow as "Files never left your device." The converter is designed to process selected images in the browser rather than send them to a server, so local processing is the core privacy advantage.
Open the downloaded PDF before sending it through WhatsApp or uploading it to Absher or another government portal. Confirm the first page, page count, orientation, margins, file size, and image legibility. A PDF is a standardized document format, and ISO maintains the PDF 2.0 reference, but the recipient's current rules still come first. If it is rejected, check that service's requirements rather than assuming the generated file will be accepted.
