PNG to PDF converter

Convert PNG files to PDF without the quality loss most converters sneak in: PNGs embed natively here, never re-encoded to JPEG, so the crisp edges of screenshots, diagrams and text captures stay pixel-perfect. That is precisely why PNG-heavy documents — UI screenshots for a bug report, whiteboard captures, signature images — deserve a converter that treats PNG as PNG. Everything runs in your browser; nothing is uploaded.

JPG and PNG files were embedded without recompression; phone photos with rotation data were straightened first.

How to use this tool

  1. Add your PNG files

    Drop one or many PNGs — screenshots, exported charts, scanned signatures. Each appears as a thumbnail in page order.

  2. Arrange and choose a page size

    Drag to reorder, then pick A4 or Letter for documents, or "Fit to image" so each page matches its screenshot exactly.

  3. Convert and download

    The PDF is assembled on your device with the PNG data embedded losslessly — text in screenshots stays razor sharp.

Questions people ask

Does converting PNG to PDF lose quality?

Not here. The PNG's own bytes are embedded into the PDF unchanged — no JPEG re-encoding, so the hard edges of text and lines in screenshots never grow fuzzy halos. Many converters silently convert to JPEG; this one does not.

What happens to PNG transparency?

The alpha channel is preserved in the embedded image, and PDF viewers show transparent areas against the white page — so a transparent-background logo or signature prints exactly as if stamped on paper.

Why convert screenshots to PDF instead of sending the images?

One PDF keeps ten screenshots in a fixed order with consistent page sizes — far easier to review than a zip of images that every chat app compresses and reorders. It is the standard way to submit UI evidence, assignment answers and payment proofs.

Can I mix PNG with JPG photos in one PDF?

Yes — add both. Each format is detected by its actual content and embedded the native way: PNGs losslessly, JPGs without recompression.

Which page size should I pick for screenshots?

"Fit to image" makes each PDF page exactly the screenshot's size — no white borders, no scaling. Choose A4 only when the PDF is headed for print or a portal that expects standard pages.

Are my images uploaded?

No — the PDF is built entirely in your browser. Screenshots of dashboards, chats and account pages often contain more private data than people notice, which is a good reason to keep the conversion on your own device.
