Convert PNG to PDF: what to know

Screenshots, scanned documents exported as PNG, diagrams and app mock-ups all end up needing to travel as a PDF at some point: a bug report with numbered screenshots, an expense claim, a design review. PNG is a lossless format, and this page keeps it that way — the PNG data is embedded in the PDF without re-encoding, on your device.

How to convert PNG to PDF

Add the PNG files above (drag and drop works, and so does pasting a screenshot straight from the clipboard). Order them with the arrows, or Sort by name if they were saved with a timestamp or a counter. Choose Fit to image for a page per screenshot at its natural size, or A4 / US Letter for a document that prints cleanly, then click Create PDF.

One PDF for the batch is the default. Switch Combine off to produce one PDF per PNG — handy when a form wants each page uploaded separately.

Lossless in, lossless out

PDF supports PNG-style images natively (Flate-compressed pixels), so Toolkitta writes the PNG's pixels into the document without converting them to JPG. Text in screenshots stays razor sharp, flat colours stay flat and there are no compression halos around letters and lines. The PDF is roughly the size of the PNGs it contains.

Transparent PNGs — logos, cut-outs, UI elements exported with a transparent background — keep their transparency inside the PDF, and viewers show the page's white behind them. If you would rather have a specific colour behind a transparent image, flatten it in the converter first (JPG or PNG with a background colour) and send the result here.

Screenshots and page size

Phone screenshots are tall (for example 1170 × 2532 pixels) and desktop screenshots are wide. With Fit to image, each page takes the exact shape of the screenshot, so nothing is scaled and the PDF reads like a stack of images. With A4 or US Letter and Auto orientation, tall screenshots go on portrait pages and wide ones on landscape pages, each scaled to fit inside the margins. Choose a margin of 10 or 20 mm if the document will be printed or annotated.

Keeping the file small

PNG screenshots are already compact, but full-resolution scans saved as PNG can be 10–30 MB each. Reduce file size re-encodes every image as a JPG at quality 80 with the long side capped at 2480 pixels, which turns a 25 MB PNG scan into a page of a few hundred kilobytes with no visible loss on paper. Leave it off for screenshots and graphics with text, where lossless matters more than size.

Questions about PNG to PDF

Is the PNG compressed or converted to JPG?
No — unless you turn on Reduce file size. The pixels are stored losslessly, exactly as in the PNG.
What happens to transparency?
It is kept. Viewers show the page background (white) through transparent areas.
Can I paste a screenshot?
Yes. Copy a screenshot and press Ctrl/Cmd+V on this page; it joins the queue like a dropped file.
Are my files uploaded?
No. Everything runs in your browser; the files stay on your device.

How to make a PDF from images

  1. Add up to 20 images — JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF. They stay in your browser.
  2. Put them in order with the arrows (or Sort by name), then choose Fit to image for screen use or A4 / US Letter for a printable document.
  3. Click Create PDF and download the file — or send it to PDF to Image, or keep one PDF per image by turning off Combine.

JPG and PNG files are embedded exactly as they are, so nothing is re-compressed unless you turn on Reduce file size. HEIC, WebP, AVIF, GIF, BMP, SVG, ICO and TIFF are decoded first and stored as JPG (or PNG when transparent).

Useful details

Are my images uploaded?

No. The PDF is written in your browser and the images never leave your device. Keep the tab open until you download or send the result — reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.

Which images can I use?

JPG, PNG, WebP, HEIC/HEIF (iPhone photos), AVIF, GIF, BMP, SVG, ICO and TIFF, up to 20 files, 20 MB each and 100 MB per batch, at most 40 megapixels each. Animated files contribute their first frame. PDFs are not accepted here — use PDF to Image for those.

Does converting lower the quality?

Not for JPG and PNG: their bytes are placed in the PDF unchanged. Other formats are decoded and stored as JPG at quality 92 (or lossless PNG when transparent), which is visually identical. Reduce file size is the only setting that trades quality for size, and it is off by default.

How do I keep the PDF small?

Turn on Reduce file size: every image becomes a JPG at quality 80 with the long side capped at 2480 pixels — about 300 dpi on A4 — which typically shrinks phone photos six to eight times. For an exact budget, compress the images first with a target size and send the results here.

What do Fit to image, A4 and US Letter mean?

Fit to image makes each page exactly the size of its image, so nothing is scaled or padded. A4 and US Letter make standard printable pages; each image is scaled to fit inside the margins and centred. Auto orientation turns wide images onto landscape pages.

Why did my sideways phone photo come out upright?

Phones store many photos rotated with an orientation flag. Toolkitta reads the flag and rotates those photos before placing them, so the PDF shows them the way your phone does. The file details say how many photos were rotated.

Is metadata copied into the PDF?

No. EXIF data such as camera settings and GPS location is not written into the document; only the picture is. The PDF's own properties list Toolkitta as the producer and the creation time.

How do I continue in another tool?

Use Send to under the finished PDF to open PDF to Image with it loaded, or start from the compressor, cropper or converter and use Send to → Image to PDF from their results.
