PNG to PDF
Convert PNG images to PDF in your browser. Free, private, no upload or watermark. Screenshots become clean PDF pages losslessly.
About this tool
Screenshots are usually PNGs, and sooner or later someone asks for them as a PDF. This tool embeds PNG images into PDF pages losslessly, right in your browser, with no upload, watermark, or signup.
Each image becomes its own page sized to the image, and because PNG embedding in PDF is lossless, text in screenshots stays perfectly crisp.
Common uses
- Turn screenshots into a PDF to attach to a report or ticket
- Convert PNG scans or forms into documents portals will accept
- Create print-ready PDFs from PNG graphics
Automate via API
The same conversion is available as a REST endpoint for scripts, pipelines, and backends. POST the file, get the converted file back:
curl -X POST https://formatably.com/api/v1/tools/png-to-pdf \ -H "X-Api-Key: YOUR_API_KEY" \ --data-binary @photo.png \ -o photo.pdf
Direct requests accept up to 4 MB; the large-file flow handles up to 100 MB. Both are covered in the API documentation · Get an API key
PNG notes
PNG is the lossless workhorse: screenshots, logos, UI graphics, and anything needing transparency. Every device and program on earth opens it. The tradeoff is size: photos stored as PNG are several times larger than JPEG.
- PNG is lossless, so converting into PNG never loses quality, but converting a photo to PNG can triple its size.
- Transparency is preserved in PNG; JPG has no transparency at all.
PDF notes
PDF is the fixed-layout document format for sharing, printing, and archiving. Wrapping images into a PDF makes them paginated and universally viewable; extracting images from a PDF renders its pages back into pictures.
- Each image becomes its own PDF page sized to the image's dimensions.
- Rendering PDF pages to images rasterizes them; text in the output is pixels, not selectable text.
Frequently asked questions
Will text in my screenshot stay sharp?
Yes. PNG data is embedded losslessly, so the PDF shows the exact pixels of your screenshot. Note the text is still an image; it will not be selectable in the PDF.
What page size does the PDF use?
Each page is sized to the image itself rather than forced onto letter or A4 paper, so nothing is cropped or padded with margins. Viewers and printers scale it to fit paper automatically.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly and the canvas API; your files never leave your device. There are no ads and no trackers on tool pages. You can verify this yourself: open your browser's developer tools, watch the Network tab while converting, and you will see no upload requests. It even works offline once the page has loaded.
Is there a file size limit?
In the browser there is no hard limit; you are bounded only by your device's memory, and files of a few hundred megabytes are usually fine. The REST API accepts files up to 4 MB in a direct request, or up to 100 MB using the large-file upload flow described in the API docs.
