Convert Image to PNG

Convert JPG, WebP, and other formats to lossless PNG — the right choice when you need transparency support or pixel-perfect quality. The conversion is free, takes one click, and runs entirely in your browser, so nothing is ever uploaded to a server.

How to convert an image to PNG with Allypdf

  1. Add the image you want to convert.
  2. Convert it to PNG locally.
  3. Download the PNG.

Why "no upload" matters here

PNG conversions are common in design and documentation work — logos, screenshots, interface mockups — much of it unreleased or client-owned. Allypdf converts on your device, so pre-launch assets and client material never pass through a third-party server on the way to becoming a PNG.

Common uses

  • Convert a JPG logo to PNG to place it cleanly onto a colored background.
  • Turn a WebP image into PNG for a tool that only imports PNG.
  • Convert graphics to lossless PNG before editing them further.
  • Standardize mixed-format screenshots to PNG for documentation.

Frequently asked questions

How do I convert an image to PNG for free?

Open the Convert to PNG tool, add the image, and download the PNG — one click, free, no account.

Does PNG keep transparency?

Yes. PNG supports an alpha channel, so transparent areas are preserved where the source format has them, and kept intact for editing.

When should I use PNG instead of JPG?

Use PNG for logos, screenshots, line art, and anything needing transparency or razor-sharp edges; use JPG for photos where smaller files matter more.

Are my files uploaded?

No. Conversion runs fully in your browser, so unreleased designs and client assets stay on your machine.

Will converting a JPG to PNG improve its quality?

No — no conversion can restore detail the JPG already discarded. What PNG does guarantee is that no further quality is lost from that point on: every subsequent edit and save keeps the pixels exactly as they are, which is why editors prefer working in PNG.
