About this tool
PNG is the format screenshots default to, and it is what people use for scans they do not want compressed. Both end up needing to become a PDF, because that is what forms, portals and colleagues expect - one file, pages in order, printable. This tool wraps each PNG as a page. The one behaviour worth knowing in advance concerns transparency: PNG supports transparent backgrounds and PDF pages do not, so any transparent area is filled with white. That is almost always what you want for a document, but it surprises people converting a logo with a cut-out background. Images are embedded at their original resolution rather than re-compressed, so a screenshot stays exactly as sharp as it was. Note that PNG screenshots of text are pictures, not text - the resulting PDF is not searchable. Everything runs in your browser using pdf-lib, so nothing is uploaded.
How to use this tool
- Add your PNG filesDrop in one or several. They are read locally, with nothing uploaded at any point.
- Arrange the page orderThe PDF follows the order shown on screen, so set it before generating.
- Choose the page setupA4 or Letter, with images fitted proportionally so nothing is stretched or cropped.
- Create and downloadOne PDF containing every image as a page, ready to submit or send.
How to convert PNG to PDF
Add your PNG files, put them in order and download one PDF with a page for each image. It suits screenshots, diagrams and scans saved as PNG, which keep crisp text because PNG does not blur edges the way JPG can.
PNG files are often much bigger than JPGs, so a PDF made from many screenshots can be large. If you hit an upload limit, run the PDF through the compressor.
Key features
- Turns a folder of screenshots or scans into the single PDF that forms and portals require.
- Images embedded at original resolution rather than re-compressed, so text in screenshots stays legible.
- Runs in your browser, so documents and screenshots never leave your device.
- Page order under your control before anything is generated.
- No account, no page limit and no watermark.
Common uses
- Combining screenshots into one document for a bug report or process guide.
- Submitting scanned pages saved as PNG to a form that requires PDF.
- Packaging design mockups into a single file for a client.
- Turning a set of chart or dashboard exports into one report.
- Preparing evidence or documentation where a single ordered file is expected.
Tips for better results
- Check the order before generating. Reordering afterwards means splitting the PDF or starting again.
- PNG screenshots produce large PDFs. If the file exceeds an upload limit, run it through the PDF Compressor.
- Transparent areas become white. If that matters, set the background you want in the image first.
- For photographs rather than screenshots, JPG to PDF gives a much smaller file with no visible difference.
- The result is images of text, not text. Use OCR Image to Text first if you need it searchable.
Mistakes to avoid
- Expecting transparency to survive. PDF pages have no transparent background - the area becomes white.
- Adding images in the wrong order and noticing only after generating.
- Using PNG for photographs, producing a PDF several times larger than necessary.
- Expecting the text in screenshots to be searchable in the PDF. It is a picture of text.
- Uploading sensitive scans to a server-based converter. This one processes locally.

Frequently asked questions
Transparent areas are filled with a white background in the PDF, since PDF pages don't support transparent backgrounds the way PNG files do.
Use this tool for an all-PNG set; if you need to combine formats, convert everything to PDF pages separately and then merge the resulting PDFs with the Merge PDF tool.
No server-imposed limit, since processing is local. Very large batches of high-resolution PNGs use browser memory, so close other heavy tabs if you are adding hundreds.
No. The PDF is assembled in your browser with pdf-lib, so screenshots and scanned documents never leave your device.
Because PNG is lossless and stores every pixel exactly, which is expensive for anything photographic. For photos, JPG to PDF produces a far smaller file. For screenshots, PNG is the right choice - run the result through the PDF Compressor if it needs to be smaller.
No. The PDF contains images of text, not text itself. Run the images through OCR Image to Text first if you need searchable content.
Use the original full-size screenshots rather than resized copies, and crop away empty space first so the content fills more of the page. Text in screenshots stays crisp because PNG is lossless.
Number your screenshots in the order of the steps, add them all here, and the PDF keeps that order - a quick way to share instructions or bug reports as a single file.
PNG pages of photos are large because PNG is lossless. Run the result through the PDF compressor, or convert photo-like images to JPG before building the PDF.
