PDF to PNG
PDF to PNG renders pages to lossless PNG files, optionally with a transparent background instead of white. PNG is the right choice for diagrams, line art and screenshots where JPEG artefacts would be visible.

How to PDF to PNG
Add your PDF
Drop the file in. Nothing is uploaded — rendering happens on your device.
Set resolution and pages
PNG is lossless, so resolution is the only quality control that matters.
Download the PNGs
Save them individually or as a single ZIP.
Lossless pages, and when you need them
PNG compression is lossless: what comes out is bit-for-bit what was rendered. On pages made of flat colour and sharp boundaries — text, tables, charts, diagrams, screenshots — that is exactly right, and it is precisely the content JPEG handles worst.
PNG also carries an alpha channel, so it is the only one of the two formats that can give you a transparent background. For a logo, a diagram or a signature that will sit on top of something else, there is no alternative.
A worked example
Four slides from a deck are exported to drop into a report. As JPEGs at 150 DPI, every heading sits in a faint cloud of grey speckle that is obvious at full zoom. The same pages as PNG are perfectly crisp, at roughly three times the file size — a few hundred kilobytes each, which for four images is a difference nobody will ever notice.
Limitations worth knowing
- Files are larger than JPEG, typically two to five times for a text page and considerably more for photographs.
- For genuinely photographic pages the extra size buys nothing visible — use JPG for those.
- Exporting hundreds of pages at 300 DPI produces a very large archive; check one page first before committing to a full batch.
- The output is an image, so text in it is no longer selectable or searchable.
- Resolution is fixed at export. Rendering again from the PDF is free, so err upward.

PDF to PNG — frequently asked questions
PNG is lossless, so text edges, thin lines and flat colour stay crisp. JPEG compression puts visible fuzz around sharp edges, which is exactly what a page of text is made of. The cost is file size — a PNG of a photo can be several times larger than the equivalent JPEG.
It leaves the page background empty instead of filling it white, so anything the PDF does not draw shows whatever is behind the image. Useful for putting a logo or a diagram on a coloured slide.
The compression is lossless, so nothing is lost relative to what was rendered. The resolution you pick still determines how much detail gets rendered in the first place.
Considerably larger than JPG. A text-heavy A4 page at 150 DPI is typically 100-300 KB as PNG against 40-80 KB as JPEG. At 300 DPI, expect four times that.
