DPI Settings Guide

Web & Screens

72-96 DPI is perfectly optimized for immediate web posting, email attachments, or messaging previews. This yields exceptionally small file sizes.

Professional Portfolios

150 DPI represents the balanced sweet-spot, maintaining great vector and graphic text sharpness for slide decks, reports, or portfolios.

Print & OCR

300-600 DPI compiles raw pixels at print-shop press densities, ensuring text remains sharp for physical print editions or downstream OCR processors.

How It Works

1

Upload PDF

Drag or select your document file.

2

Adjust Settings

Choose output format (JPG/PNG/WebP), DPI resolution, and quality.

3

Extract Images

Convert and download page layers as high-quality image archives.

Frequently Asked Questions

Is my personal data safe?
Extremely. By converting documents fully client-side inside your browser environment using Canvas contexts, your PDF content never gets uploaded to any remote server. Your files stay 100% private.
Can I extract transparent PNG layers?
Yes. By choosing the PNG/WebP format options and toggling background to transparent, you can extract transparent layer masks if the PDF had transparent layout layers.
Does the range selection support custom sets?
Yes. You can specify precise lists (e.g. 1-4, 8) and only those specific page indexes will be processed into image blobs.

Choosing the Right Format and Resolution

PNG or JPG, and at what DPI

The right export settings depend on where the image is going. Too low and text gets fuzzy; too high and the file balloons for no visible gain:

DestinationFormatResolution
Web page or chat previewJPG96–120 DPI
Slide deck or report figurePNG150 DPI
PrintingPNG300 DPI
Text-heavy page (sharp letters)PNG150–300 DPI
Photo-heavy page (small file)JPG120–150 DPI

The resolution math

Pixels = inches × DPI. An A4 page (8.27 × 11.69 inches) at 150 DPI becomes roughly 1240 × 1754 pixels — crisp on any screen. At 300 DPI it doubles to 2480 × 3508, which is print territory and four times the file size. If the image looks blurry where you pasted it, you exported at too low a DPI for the display size; re-export higher rather than upscaling the image afterwards.

Why convert pages to images at all

Images open everywhere — no PDF reader, no download prompt. People convert pages to share a single page on WhatsApp, paste a figure into PowerPoint, or post a flyer as a feed image. Heading the other direction, JPG to PDF rebuilds a document from images; exported images that are too heavy shrink well in the image compressor, and splitting first avoids exporting pages you don't need.
