Convert PNG to PDF Free Online — Single or Multiple Images

Convert one or multiple PNG images to a PDF document free — no account, no watermark. Combine screenshots, photos, and graphics into a single shareable PDF.

PNG to PDF conversion is one of the most searched image tasks — turning screenshots, designs, scanned pages, or exported graphics into a single, professional PDF document. Whether it's one image or 50, the process takes under 30 seconds for free.

How to convert PNG to PDF free — step by step

  1. 1
    Open the image to PDF tool
    Go to editdocsai.com/tools/jpg-to-pdf in any browser. Supports PNG, JPG, JPEG, HEIC, BMP, and TIFF images.
  2. 2
    Upload your PNG files
    Upload one PNG for a single-page PDF, or multiple PNGs for a multi-page PDF. Each image becomes one page.
  3. 3
    Set paper size and orientation
    Choose A4, Letter, or "fit image" (PDF page matches exact image dimensions). Portrait or landscape. In AI Studio, type "convert these PNGs to A4 PDF portrait".
  4. 4
    Download your PDF
    PDF is generated instantly. Download and share. File deleted after 60 minutes.

Combine multiple PNG files into one PDF

Upload all your PNG images at once — screenshots of a process, scanned pages, design exports, or product photos. Each PNG becomes one page in the output PDF in the order uploaded. This is useful for: submitting a multi-page application as a single PDF, creating a PDF portfolio of design work, combining screenshots into a tutorial document, and archiving a set of images in a single shareable file.

PNG to PDF vs PNG to JPG first — which is better?

PNG images in a PDF are stored at their original lossless quality — no extra compression is applied during conversion. This makes PNG→PDF ideal for screenshots with sharp text, technical diagrams, and graphics where every pixel matters. The resulting PDF may be large if the PNGs are high-resolution. To reduce PDF size after conversion, compress it at editdocsai.com/tools/compress-pdf. If file size is more important than pixel-perfect quality, convert PNGs to JPG first at 90% quality, then to PDF — the resulting PDF is typically 50–70% smaller.

Tip: convert screenshots to PDF for documentation
Software documentation, bug reports, tutorial guides — all commonly assembled from screenshots. Upload all your PNG screenshots to editdocsai.com/tools/jpg-to-pdf in order, and download a single PDF. For a professional touch, merge with a cover page PDF created in Canva or Word at editdocsai.com/tools/merge-pdf.

Frequently Asked Questions

Can I convert multiple PNG files into one PDF?+
Yes. Upload all your PNGs at once and they are combined into a single multi-page PDF, one image per page.
Is there a limit to how many PNG files I can convert?+
No hard page limit. Files up to 50MB total are supported via the web tool. For larger batches, use editdocsai.com/batch.
What paper size will the PDF use?+
A4 by default. In AI Studio, specify "Letter size" or "fit to image dimensions" for exact pixel-to-page mapping.
Does the PDF preserve PNG transparency?+
When PNG transparency is present, it is rendered with a white background in the PDF (PDF format does not support page transparency). If transparent areas must stay transparent, keep as PNG and do not convert to PDF.
Can I convert a PNG to a searchable PDF?+
Yes — after converting the PNG to PDF at editdocsai.com/tools/jpg-to-pdf, upload the result to editdocsai.com/tools/ocr-pdf to apply OCR and make any text in the image searchable and selectable.
