Export Pages at Custom DPI - Free Online Browser Tool

Rasterise PDF pages at an exact resolution you set, for print or print-shop submission.

A print shop asking for "300 DPI" needs actual 300 DPI files, not a PDF they have to guess at. Setting the resolution explicitly is also how you keep a large-format export from becoming an unexpectedly enormous file.

This export pages at custom dpi utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the Export Pages at Custom DPI Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the PDF

    Any document; pages are rendered one at a time.

  2. Choose the resolution

    72 for thumbnails, 300 for commercial print, 600 for fine line art.

  3. Choose the format

    PNG is lossless and large. JPG and WebP are much smaller and fine for photographic pages.

  4. Optionally limit the pages, then download

    One page gives you one image. Several give you a ZIP with a note listing the pixel size of each.

Frequently Asked Questions

What pixel size should I expect?

An A4 page at 300 DPI is roughly 2480 by 3508 pixels. Multiply out from there for other sizes, and remember both dimensions grow together.

Why is the file so much bigger than the PDF?

Because an uncompressed bitmap of one A4 page at 300 DPI is about 26 million pixels, where the equivalent PDF page might be a few hundred kilobytes of vector data. Rasterising is inherently expensive.

Is higher DPI ever wrong?

Yes, when the source has no more detail to give. Upscaling a 72 DPI scan to 600 DPI produces a large file with nothing extra in it.

Which format should I choose?

PNG for line art, screenshots and text, where JPEG artefacts show. JPG for scanned photographs, where it is several times smaller at no visible cost.

Do the pages come out at a different physical size?

No. The output has the same physical dimensions as the original; only the pixel density of the raster changes.
