PNG to PDF converter

When converting PNG images to PDF helps

A PNG file is useful for a screenshot, diagram, or graphic, but a collection of separate images can be awkward to send or print. Converting those images to a PDF gives you one document with a predictable reading order. You might combine assignment screenshots, save a set of receipts, prepare visual instructions, or assemble a short portfolio. Each selected image becomes its own page, so the recipient can move through the material without opening several files. The converter also accepts JPG and JPEG photos, allowing you to combine different supported image formats in the same document.

Start with clear, complete source images

Before selecting files, open the images and check that all the information you need is visible. Crop unwanted desktop borders, straighten photographed paperwork, and remove duplicate screenshots. If text is already blurry in the original image, putting it inside a PDF will not restore missing detail. For diagrams or interface screenshots, keep the original PNG when possible. For photographs, an existing JPEG is usually appropriate. Avoid repeatedly saving an image in different formats just to prepare it for this tool. Use the clearest available original and keep a separate copy if you intend to edit it.

Add images and set the reading order

Select Choose images or drop supported files into the upload area. Although it looks like a familiar upload box, the images are read locally by your browser for this tool. Review the numbered list before creating the PDF: the first image becomes page one, the second becomes page two, and so on. Use the move controls to place a cover image first or keep instructions in the correct sequence. Rotate sideways pictures until they are readable. Removing an item only removes it from this selection; it does not delete the original file from your device.

Choose A4, US Letter, or Fit image

The page size should match how the document will be used. A4 is a practical choice for many printed documents, while US Letter suits workflows that use that paper format. Fit image makes the page follow the image dimensions, with your chosen margins added around it. This is useful for screenshots or graphics that do not match standard paper proportions. For A4 and Letter, images are scaled to fit within the available space while keeping their proportions. A wide screenshot on a tall page may therefore leave blank space. That space prevents the image from being stretched or cropped.

Use orientation and margins deliberately

Auto orientation chooses a portrait or landscape page to suit each image. This allows one PDF to contain a mixture of tall and wide pages. Select Portrait or Landscape when consistent page orientation is more important for your document. Narrow margins give the image a small amount of breathing room; Wide margins leave more space around it. None removes the added margin, although fitting an image to a different page shape can still leave unused space. Some printers also have their own unprintable edges. Review the print preview before assuming that a margin-free PDF will print to the paper edge.

Understand image quality and PDF file size

This converter places your original images in the PDF without an optional quality slider or a deliberate reduction in pixel resolution. JPEG images are not repeatedly recompressed just to build the document. However, preserving image detail does not mean the result will always be smaller than the source files. A PDF includes page structure and other information, and detailed PNG images can produce a large document. If you need a smaller attachment, resize unnecessarily large source images before conversion. Keep enough pixels for the intended reading or printing size, especially when your images contain small text.

Know what happens to transparency and text

PNG graphics can contain transparent areas. In the generated document, these areas appear over a white page background, which is useful for ordinary viewing and printing. Check pale logos or white lettering carefully because they may be difficult to see against white. Text that appears inside a screenshot remains part of that image. This tool does not run optical character recognition, so converting a screenshot into a PDF does not automatically make its words selectable, searchable, or editable. If you need to change the wording, edit the source document or use a separate OCR workflow before finalizing the material.

Keep conversion on your own device

The PNG to PDF tool creates the document in your browser. It does not send your selected images to the ConvertFoto server for conversion, and it does not share the PDF-to-Word service queue. You do not need an account to create or download a file. Keep the page open until the PDF is ready, and save the download before leaving. Refreshing the page clears the current working selection. A PDF you have already downloaded remains in your device's downloads folder until you move or delete it. Review sensitive screenshots before sharing the finished document with someone else.

Work within the browser's practical limits

You can select up to 20 images, with a maximum of 20 MB per image and 100 MB across the selection. The tool also limits image dimensions to 25 megapixels per image and 80 megapixels in total. These limits help control memory use, because a compressed file can require much more space when decoded. They are upper limits, not a guarantee that every phone can handle the largest possible batch. If your device slows down, use fewer images, close other heavy tabs, or reduce very large image dimensions. Several smaller PDFs may be easier to create and share.

Resolve common conversion problems

If a file is rejected, check that it is a genuine PNG or JPEG rather than another format with a renamed extension. Export HEIC, WebP, SVG, or other images to PNG or JPEG first. Animated PNG files need to be saved as a single still image for this tool. If an image appears sideways, use its rotation control and check the thumbnail again. If PDF creation fails, try one small image to confirm the browser can complete the task, then add more gradually. Changing your selection or layout clears an earlier result so you can create a fresh PDF with the current settings.

Download, review, and continue editing

Choose a descriptive file name, select Create PDF, and wait for the download button. Open the saved document and check its page count, order, orientation, and readability at a normal zoom level. For printing, review the actual paper size and scaling options in your PDF viewer. For sharing, confirm that the attachment size suits the destination. You can use the ConvertFoto PDF Editor afterward to add notes, highlights, or signatures. Keep the original image files as well: they are useful if you later need to change a screenshot, rearrange the material, or create a version for a different paper size.
