Why pdfdots?
Private by design
Most tools process files locally in your browser. Office conversions run on our EU server and are deleted right after; anything you save to My files is encrypted.
Generous free plan
A free account with Google sign-in and no credit card: 3 tasks a day, files up to 10 MB, every tool. Need more? The paid plans (Bronze, Silver and Gold) raise the daily limit, with no daily limit at all on Silver and Gold, and accept larger files.
Fast
For browser tools there's no upload or download queue. Work starts the moment you drop a file and finishes at the speed of your own computer.
Works everywhere
Windows, Mac, Linux, iPhone, Android or Chromebook — if it has a modern browser, pdfdots runs on it. Nothing to install.
When PNG beats JPG
PNG is a lossless format: every pixel is stored exactly, with none of the blocky artifacts JPG compression can leave around sharp edges. That makes PNG the better choice for pages with text, charts, diagrams, code, UI screenshots and line drawings. Put a page of a technical manual through both converters and the PNG text edges will look cleaner, especially at 72 or 150 DPI.
The downside is size. For pages full of photos, a PNG can be several times larger than the equivalent JPG with no visible benefit. A practical rule: text and graphics go to PNG, photos and scans go to JPG. Resolution works the same as in PDF to JPG — 72 DPI for small previews, 150 DPI for screens and documents, 300 DPI for print or detailed zooming.
Each page becomes a separate PNG. Single-page PDFs give you one image; multi-page PDFs give you a ZIP of numbered images in page order. The conversion runs in your browser, so the PDF stays on your device the whole time. That makes it handy for turning pages of internal documentation into images for a wiki, a slide deck or a support ticket without sending anything to an outside service.
Our take
We choose PDF to PNG when the page contains sharp edges: a floor plan, a chart for a presentation, a logo from a brand guide, or a screenshot-like page that will be pasted into documentation.
For slides and documentation we render at 150 DPI; for anything that will be printed or cropped heavily we go to 300 DPI. PNG files get large quickly at high DPI, so we avoid 300 on long documents unless we really need it.
The pitfall: a scanned photo or a colourful brochure page saved as PNG can end up several times bigger than the same page as JPG, with no visible benefit. For photos and scans we switch to PDF to JPG. If what you actually want is the text, OCR PDF followed by copy and paste beats any image.

Frequently asked questions
Is PNG better quality than JPG?+
PNG is lossless, so text and graphics stay perfectly sharp. For photos the visible difference is small and JPG files are smaller.
Are the PNGs transparent?+
No. PDF pages are rendered with their normal white background.
What DPI should I choose?+
150 DPI suits most screen uses; choose 300 DPI for printing or fine detail.
Why is the download a ZIP?+
When a PDF has several pages, all PNGs are bundled into one ZIP archive.
Is anything uploaded?+
No. The conversion runs entirely in your browser.
