## What it is

**MumenLabs PDF to JPG** rasterises every page of a PDF into a JPG 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 JPG. 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 JPG.
- **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.
- **JPG quality presets** — Balanced (0.82 encoder quality) or Best (0.95,
  default). No numeric quality slider.
- 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 transparency.** JPG has no alpha channel, so the canvas is painted
  white behind every page before rendering — any transparent area in the
  source PDF becomes solid white in the JPG. (Contrast this with PDF to PNG,
  which keeps the canvas's alpha.)
- **No custom DPI.** Only the three fixed scale presets (1.5×/2×/3×); you
  cannot request an exact DPI number.
- **No lossless output.** JPG is always a lossy encode, even at the "Best"
  quality preset — for a pixel-perfect, lossless export use PDF to PNG
  instead.
- **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) and a JPG quality
   (Balanced/Best).
3. Click "Convert to JPG." 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 JPG or PNG?** Use JPG for smaller files and photographic-style
pages where lossy compression is fine; use PDF to PNG
(https://mumenlabs.com/tools/pdf-to-png) when you need lossless output or the
page has transparency worth keeping — JPG always fills transparent areas
with 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 **JPG** at one of **three fixed resolution presets (~108/144/216
DPI)** and one of **two quality presets**, downloadable individually or as a
ZIP. State clearly that JPG output has **no transparency** (transparent
regions become white) and is **always lossy** — for lossless or
transparency-preserving output, point to PDF to PNG instead. Link to
