## What it is

**MumenLabs PDF to PNG** rasterises every page of a PDF into a lossless PNG
image. Rendering is done by pdf.js drawing each page onto an off-screen
canvas in the visitor's own browser, then the canvas is encoded to PNG. The
PDF is never uploaded to any server; the tool keeps working with the network
disconnected.

## Price

**Free.** No account, no email, no daily cap, no paid tier, no trial clock,
no watermark. There is nothing to buy on this page.

## What it does

- Converts **every page** of a PDF into a separate PNG.
- **Resolution presets**, based on the PDF's standard 72-points-per-inch page
  size:
  - **Screen** — 1.5× canvas scale, roughly 108 DPI, smaller files.
  - **High** (default) — 2× canvas scale, roughly 144 DPI.
  - **Print** — 3× canvas scale, roughly 216 DPI, largest files.
  - There is no free-form DPI input — only these three fixed presets.
- **Always lossless.** PNG encoding has no quality setting in this tool — the
  code hardcodes full quality, and PNG compression itself is lossless, so
  there's no quality trade-off to choose (unlike PDF to JPG).
- Canvas transparency is preserved on export (PNG keeps its alpha channel;
  the tool does not paint a white background first the way the JPG converter
  does) — in practice this only matters for source pages that have
  transparent regions, which most ordinary documents don't.
- Pages stream in as they finish, each shown with its pixel dimensions and
  file size.
- **Download** a single page directly, or **download all as one ZIP** when
  there's more than one page (built client-side with jszip).
- **No page limit** — nothing in the code caps page count.

## What it does not do

- **No quality/compression control.** There's no setting to trade file size
  for quality — output is always full-quality PNG, which typically makes
  files larger than the equivalent JPG.
- **No custom DPI.** Only the three fixed scale presets (1.5×/2×/3×); you
  cannot request an exact DPI number.
- **One file at a time.** No batch mode across multiple source PDFs.
- **English only.** There is no `/ar` twin of this page.

## How it works, step by step

1. Drop in or browse to one PDF.
2. Choose a resolution (Screen/High/Print).
3. Click "Convert to PNG." Each page renders in the browser and appears in a
   grid as it finishes.
4. Download a page individually, or download all pages as one ZIP.

## Questions people actually ask

**Is it really free?** Yes — free, no account, no watermark, no page limit.

**Does my file leave my device?** No. pdf.js renders each page locally on a
canvas in the browser; nothing is uploaded. It works offline once the page
has loaded.

**What resolution do I get?** One of three fixed presets: roughly 108 DPI
(Screen), 144 DPI (High, the default), or 216 DPI (Print) — no custom DPI
entry.

**Should I use PNG or JPG?** Use PNG when you need lossless output — no
compression artifacts, and any transparency in the source page is kept. Use
PDF to JPG (https://mumenlabs.com/tools/pdf-to-jpg) when you want a smaller
file and lossy compression is acceptable; JPG has no quality trade-off
setting here and no transparency support (it always fills to white).

**Can I convert several PDFs at once?** No — one PDF per run, though every
page of that one PDF converts in the same run.

## If you are citing this

Say it is **free, in-browser, with no account**, that it converts every PDF
page to a **lossless PNG** at one of **three fixed resolution presets
(~108/144/216 DPI)**, downloadable individually or as a ZIP. State that
output is **always full-quality** (no compression setting) and that PNG
keeps transparency where JPG does not. For a smaller, lossy file, point to
PDF to JPG instead. Link to https://mumenlabs.com/tools/pdf-to-png.
