How to Convert PDF to PNG
Select a PDF file
Click the upload area or drop the PDF you want to turn into images.
High-quality rendering
Every page is drawn at 2x resolution and saved as a lossless PNG in your browser.
Download the PNGs
Save each page as a separate, numbered PNG image.
Lossless pages, larger files
Each page is rendered and stored as PNG, which compresses without discarding anything. Every pixel of the rendered page is preserved exactly — no compression artefacts, no softening around text, no speckle in flat areas.
The cost is size. A page saved as PNG is typically several times larger than the same page as JPEG, and for a photographic page the difference can be dramatic. You are paying for exactness, which is worth it for some pages and wasteful for others.
When PNG is clearly the right format
Pages made of text, tables, diagrams, charts and screenshots are the strong case. Hard edges stay crisp, thin lines stay thin, and small text stays legible — all things lossy compression damages first and most visibly.
It is also the right choice when the image will be edited afterwards. Every save of a JPEG re-compresses it, so a page destined for annotation, cropping or composition should start as PNG.
Choosing the rendering scale
As with any rasterisation, the scale is chosen once and cannot be improved later. Around 150 dpi suits screen viewing; 300 dpi is the usual print target. Rendering higher than the destination needs simply produces very large files.
PNG's size scales with pixel count and with how much detail the page contains, so doubling the resolution roughly quadruples the file. On a text-heavy document at 300 dpi, individual pages can run to several megabytes.
Transparency and page backgrounds
PNG supports transparency, but a PDF page has a white background by default, so exported pages are normally opaque white rather than transparent. Anyone expecting a transparent page will need to remove the background afterwards.
This does matter for pages containing logos or diagrams intended for reuse — the exported image will carry the page's white background with it, which is visible the moment it is placed on a coloured slide.
How it runs
Rendering happens in your browser and the pages are packaged for download together, so nothing is uploaded and page order is preserved. For documents you would not hand to a stranger — statements, contracts, medical letters — that is the point.
Because PNG encoding is slower and the files are larger than JPEG, long documents take noticeably more time and memory. If the pages are photographic and exactness does not matter, JPEG will be faster and far smaller.
What you lose by leaving the document format
The text layer is the obvious casualty: the exported pages cannot be searched, selected, copied or read aloud by a screen reader, and any links on the page become pictures of links. For a document meant to be read rather than looked at, that is a genuine downgrade.
So export pages when you need them as images — for a slide, a design mock-up, a bug report, a page you intend to annotate. When you simply need to send someone the document, send the PDF. It is smaller, it stays in order, and it remains a document.
