Free browser PDF tool

Convert PDF to JPG or PNG online — no upload

Render each page of a PDF as a JPEG or PNG image, right in your browser. Pick the DPI (72–300), choose the format, download one or all images. Your file never leaves your machine.

Convert PDF to image

◐ Runs locally in your browser
Made with LocusBIM — install the desktop app to batch-convert drawing sets or render high-DPI exports for print.

When you'd convert a PDF to image

Sharing a single page in an email body. Embedding a drawing in a slide deck. Posting a snapshot to a client portal that doesn't accept PDFs. Sending a quick visual to a contractor who's on a phone in the field. All of these end with "rasterise to JPG/PNG and share the image instead." LocusBIM does this locally — pdfjs-dist renders each page in your browser, no upload, no account, no watermark on the output.

How it works

  1. Drop a PDF or click the picker.
  2. Choose JPEG (smaller) or PNG (sharper for line work).
  3. Pick the DPI — 150 covers most uses; bump to 300 for print.
  4. Click Convert. Each page becomes a separate image you can download.

Print-quality output? Use the desktop.

The browser caps usable DPI at the ~300 mark before memory becomes a problem. For 600+ DPI archival rasters, batch conversion across drawing sets, or PDFs larger than a few hundred MB, install LocusBIM Desktop — free to download.

Frequently asked questions

Will the conversion happen in my browser?

Yes. LocusBIM uses pdfjs-dist (the same engine Firefox ships for built-in PDF viewing) to render each page to a canvas, then exports the canvas as JPEG or PNG. Nothing is uploaded.

What DPI should I pick?

72 DPI matches a typical screen — small files, low detail. 150 DPI (the default) gives crisp on-screen viewing and acceptable print output. 300 DPI is print-grade and produces large files; useful when you need to embed the image in a presentation or report at full size.

Why JPEG vs PNG?

JPEG is smaller for photographs and continuous-tone images. PNG is sharper for line drawings, text, and CAD output. For engineering drawings, PNG keeps stroke edges crisp; for site photos embedded in a PDF, JPEG gives a 3-5× smaller file.

What is the maximum PDF size?

There's no enforced limit. Conversion holds one page at a time in memory, so a 100-page PDF works fine on a typical laptop. Very high DPI on a large drawing (e.g. ANSI E at 300 DPI) produces large images — your browser may run out of memory at extreme combinations.
