Runs locally, never uploaded

72 = screen size, 150 = sharp on screen, 300 = print quality.

PDF

Drop a PDF here or choose a file. Every page becomes an image; nothing is uploaded.

What this tool does

It renders every page of a PDF as an image: PNG, JPG or WebP. Pick the pages and the resolution, then download pages one at a time or all of them as a ZIP. Everything happens in your browser, and the PDF is never uploaded.

Pages are drawn by Mozilla’s PDF.js, the same engine as the Firefox PDF viewer, so vector graphics, embedded fonts, scanned images and Chinese, Japanese or Korean text come out right.

How to use it

  1. Click Choose PDF… or drop a file on the page. Sample loads a two-page example PDF.
  2. Pick an Image format: PNG for text and charts, JPG or WebP for scans and photos.
  3. Pick a Resolution (DPI): 150 for screens, 300 for print.
  4. Optionally list Pages, such as 1-3, 5, 8- (8- means page 8 to the end). Leave it empty to convert every page.
  5. Each image shows its size in pixels and bytes. Use Download under a page, or Download all (ZIP). Files are named like report-01.png so they sort in page order.

Images are regenerated as soon as you change an option.

Common uses

  • Share in chat apps and social media, where PDFs often cannot be previewed but images can.
  • Put a page or chart into slides, documents or a web page as a picture.
  • Split a scanned PDF back into one JPG per page.
  • Make a thumbnail or cover image by converting only page 1 at 72 or 96 DPI.

Example

For a 12-page A4 PDF with pages set to 1-3, format PNG and 150 DPI, you get name-01.png, name-02.png and name-03.png, each about 1240 × 1754 pixels.

FAQ

› Is my PDF uploaded?

No. The PDF is parsed and drawn by PDF.js, the PDF viewer built into Firefox, running in your browser. The file never leaves your device, so it is safe for contracts, invoices and other private documents.

› Which DPI should I pick?

DPI sets the pixel size of the images. 72 matches the PDF at 100% zoom; 150 looks sharp on screens and suits sharing and documents; 300 is for printing or zooming into details. An A4 page is about 1240 × 1754 pixels at 150 DPI and 2480 × 3508 at 300 DPI.

› PNG or JPG?

Use PNG for pages of text, tables and charts: edges stay crisp. Use JPG or WebP for scans and photo-heavy pages: the files are much smaller.

› Can it open password-protected PDFs?

Yes. You are asked for the password when you open a protected PDF. It is only used inside your browser to decrypt the file.

› Why is a page too large?

Browsers limit canvas size (16384 pixels per side, about 16.7 million pixels in total on iPhone). Very large drawings at a high DPI go over that limit; choose a lower DPI.
