PDF to PNG Converter

There is no quality setting, because PNG discards nothing. The only decision is resolution, and the guidance is simple: pick it for the job, and do not go lower to save space.

If size is a problem, there are better levers than resolution:

• Compress the PNGs afterwards. PNG compression reduces the colour palette, and rendered document pages are ideal for it — a page of black text on white uses very few distinct colours, so the saving is often 70% or more with no visible change.
• Use JPG for photographic pages. If the document is a brochure or photo book rather than text, JPG is genuinely the better fit.
• Drop from 300 to 150 DPI if the images are only ever going to be viewed on screen. That alone quarters the data.

What not to do is render at a low resolution and then try to enlarge the result. The detail was never created, and enlarging produces a soft image with a large file size — the worst of both.

When PNG is the right target

• Text documents of any kind — contracts, letters, reports, forms.
• Scanned pages, where the scan already has artefacts and adding JPEG's on top makes things visibly worse.
• Diagrams, charts and technical drawings, which are made of exactly the lines JPEG handles worst.
• Anything you will edit or annotate afterwards, since lossless means repeated saves cost nothing.
• Archiving pages as images, where exactness matters more than size.

Every page, in order

A document with more than one page returns a ZIP containing every page as a separate image, numbered and zero-padded so page 10 sorts after page 9 rather than after page 1.

Some converters return only the first page. That is worse than an error, because it looks like success while most of the document has quietly been discarded.

There is a cap on pages per conversion, since rendering a long document at high resolution is substantial work. For a very long document, lower the resolution or split the PDF first.

Text becomes a picture of text

Rendering a page converts everything on it — including text — into pixels. The result is not searchable or selectable, and copying from it is impossible.

That is sometimes the point: it is a simple way to stop casual copying, though it is inconvenience rather than security, since the words remain readable and OCR recovers them. If you need the text as text, you need a PDF text extractor or OCR, not an image conversion.

What happens to your document

Browsers cannot render PDFs to images, so this runs on our server. Your upload is deleted the moment conversion finishes, the result is deleted as you download it, and anything abandoned is swept automatically.

Worth stating plainly for this tool in particular: the documents people convert are frequently contracts, bank statements, medical letters and identity papers.
