Choosing a format
The three formats are not interchangeable, and picking the wrong one is the usual reason a converted page looks worse than the PDF did.
| Format | Strength | Use it for |
|---|---|---|
| PNG | Lossless; every edge stays exactly as drawn | Text, diagrams, tables, logos, screenshots — most documents |
| JPG | Far smaller on photographic content | Pages that are mostly photographs |
| WebP | Smaller than both, at some cost in compatibility | Images headed for a web page |
The reason PNG is the default is that JPEG compression works by discarding detail the eye is bad at noticing in photographs — and it is worst exactly where documents live, at the hard boundary between black text and white paper. That is what produces the faint grey haze around letters in a JPEG of a text page. PNG has no such artefact.
Choosing a resolution
DPI decides how many pixels each inch of the page becomes, so it drives both sharpness and file size — and size grows with the square of it, which is why the jump from 96 to 300 is roughly tenfold rather than threefold.
- 96 DPI matches a screen. Right for a preview, a thumbnail or an image on a web page.
- 150 DPI is the sensible middle: readable when zoomed, still reasonable to send by email.
- 300 DPI is print quality. Choose it when the image will actually be printed, not by default.
The estimate under the page grid updates as you change these, so the trade-off is visible before you commit to it.
What conversion costs you
An image of a page is a picture of writing rather than writing. Nothing in it can be selected, searched, copied or read by a screen reader, and no amount of resolution changes that — it is inherent to the conversion, not a limitation of this tool. If the words are what you are after, PDF to Text reads them out directly, and the OCR tool handles pages that are already images.
Where images earn their place is anywhere a PDF is awkward: a slide, a social post, a message thread, a page embedded in a document that will not take a PDF, or a preview thumbnail.
Two details worth knowing
A PDF page carries no background of its own. Rendered naively, any area the page does not paint stays transparent — which is invisible in a PNG and turns solid black in a JPEG, because JPEG has no transparency to fall back on. Every page here is painted onto white first, so a JPG comes out looking like paper.
Pages are also rendered at print intent rather than screen intent. That is the fidelity appropriate to a file being written out, and it has a practical benefit: screen rendering is driven by animation frames, which browsers stop delivering to a background tab, so a long conversion left in another tab would stall. Print rendering does not depend on them, so a three hundred page job finishes whether or not you sit and watch it.
Questions
Is my PDF uploaded to convert it to images?
No. Each page is drawn onto a canvas inside your browser and encoded there by the browser itself. There is no backend, so nothing is transmitted and nothing is stored.
Which format should I choose?
PNG for anything with text, diagrams or flat colour, because it is lossless and keeps edges crisp. JPG for pages that are mostly photographs, where it is far smaller for the same apparent quality. WebP when the images are for the web and you want both, at the cost of older software that cannot open it.
What resolution do I need?
96 DPI matches a screen and is right for a preview or a web page. 150 DPI is a good middle for a document that might be printed casually. 300 DPI is print quality and produces files roughly ten times the size of the screen setting, so it is worth choosing deliberately rather than by default.
Why do I get a ZIP file?
Because a browser will only begin one download per action. A single page comes back as a single image; several pages are packed into one archive, named after the document with each page numbered inside it.
Can the text in the images still be searched?
No. An image of a page is a picture of writing, not writing, so nothing in it is selectable or searchable. That is inherent to converting a document into pictures. If you want the words, use PDF to Text instead.
Why is my JPG background black?
It should not be here. A PDF page has no background of its own, so a naive conversion leaves unpainted areas transparent and JPEG turns transparency black. Each page is painted onto white before rendering for exactly that reason.
