How to convert a PDF to images
- Drop your PDF in. It is read on your device — nothing is uploaded.
- Choose a format. JPG for photos and scans, PNG for pages of text or diagrams.
- Pick a resolution. 150 DPI suits most uses; choose 300 DPI if the result is going to print.
- Select pages, or leave it on every page.
- Convert, then download. One page arrives as a single image; several arrive as a ZIP.
Every page is rendered on your own machine. The document never leaves it.
Choosing a resolution
DPI stands for dots per inch, and it decides how many pixels each inch of the page becomes. A PDF has no inherent resolution — it stores instructions for drawing the page, not a grid of pixels — so this choice is genuinely yours to make.
For an A4 page:
| Resolution | Pixel size | Good for |
|---|---|---|
| 72 DPI | 595 × 842 | Web previews, email, thumbnails |
| 150 DPI | 1240 × 1754 | General use, on-screen reading, zooming |
| 300 DPI | 2480 × 3508 | Printing, design work, archival copies |
US Letter comes out slightly different — 2550 × 3300 at 300 DPI — because the page is wider and shorter.
150 DPI is the right default. It is sharp enough that text holds up when someone zooms in, and small enough that a twenty-page document is a reasonable download.
Go to 300 DPI when a printer or a designer has asked for it, or when the image is the archival copy of something. Do not choose it by default: files are roughly four times larger than 150 DPI, and on screen they look identical.
Drop to 72 DPI when the image is a thumbnail or a preview and size matters more than detail.
JPG or PNG?
The two formats fail in opposite directions, and the right choice depends entirely on what is on the page.
JPG compresses by discarding detail the human eye is poor at noticing. That works beautifully on photographs, where colour varies gradually. It works badly on sharp edges — and black text on a white background is nothing but sharp edges. Compressed hard, letterforms pick up a faint grey haze around them, called ringing.
PNG is lossless. Every pixel comes out exactly as rendered, so text and line art stay clean. The trade-off is size: PNG compresses by finding repetition, and a photograph has very little, so a photo-heavy page can come out several times larger than the equivalent JPG.
The practical rule: text and diagrams to PNG, photographs and scans to JPG. For a mixed document, JPG at quality 90 or above is usually the better compromise — the text softening is slight and the files stay reasonable.
Why a PDF page is not already an image
This surprises people, and it explains why conversion takes a moment rather than being instant.
A PDF does not store a picture of a page. It stores a set of drawing instructions: place this font at this size at these coordinates, stroke a line from here to here, fill this shape with this colour. Fonts are frequently embedded in the file so the text renders identically on a machine that does not have them installed.
Nothing exists as pixels until something executes those instructions. That is what a PDF viewer does every time you open a document, and it is why you can zoom to 400% and the text stays perfectly sharp — the page is being redrawn at the new size, not enlarged.
Converting to an image means running that rendering once, at a resolution you choose, and freezing the result. Sharpness above that resolution is gone, permanently, because the letterforms were replaced by a grid of pixels.
This is also why a scanned PDF behaves differently. A scan never had vector text — it is a photograph of paper wrapped in a PDF container. Converting one is closer to extraction than rendering, and the output quality is capped by whatever the scanner produced.
When you actually want images
Uploading to a system that will not take PDFs. Plenty of forms, marketplaces and older applications accept only JPG or PNG.
Posting a page somewhere. Social platforms, chat apps and forums display an image inline; a PDF becomes an attachment nobody opens.
Putting a page into a slide or a document. Dropping an image into a presentation is far simpler than embedding a PDF.
Sending a page to someone who cannot open PDFs comfortably — an older phone, a restricted work machine, a messaging app with a poor document viewer.
Making a preview or thumbnail of the first page, for a listing or a link card.
Extracting the pictures from a scan so they can be edited in an image editor.
Limits and requirements
Memory is the real limit, not file size. Each page is drawn onto a canvas before encoding, and at 300 DPI that canvas is around 35 MB while it exists. Pages are rendered one at a time and released immediately, so long documents work — they take longer.
No text extraction. The output is pictures of pages. Selecting or searching the text is not possible in an image; that needs OCR, which is a separate tool.
Password-protected PDFs will not open. Remove the password first, in a viewer that has it.
Pages render as they would print. Filled form values, highlights and stamps appear in the image the way they would come out on paper. A few things that exist only on screen — comment pop-ups, for instance — do not, because they are not part of the printed page.
Conversion continues in a background tab. Long documents keep rendering if you switch away, which is not true of every browser-based converter.
Browser support. Any modern browser on desktop or mobile. Large documents at high DPI are more comfortable on a desktop.
Privacy: how this tool handles your document
Rendering happens in your browser, using pdf.js — the same engine Firefox uses to display PDFs natively. The file is read from disk into memory on your own machine, drawn onto a canvas, encoded, and handed back. Nothing is transmitted, nothing is logged, nothing is stored, and closing the tab discards all of it.
This matters more for PDFs than for nearly any other file type. Look at what people actually convert: signed contracts, bank statements, medical letters, tax returns, invoices, passport scans, tenancy agreements. A conversion service that runs on a server receives every one of those files in full, and then has to decide how long to keep it — a decision usually documented in a privacy policy nobody read, and undermined by backups, error trackers and access logs that were never designed with document retention in mind.
The interesting thing is that none of it is necessary. Every browser already contains a complete PDF rendering engine, because every browser has to display PDFs. This tool uses that. The document goes from your disk to your screen and back to your disk, with no third step.
You can confirm it rather than taking it on trust. Open your browser's developer tools, switch to the Network tab, and convert something — no request carries your file. Or disconnect from the internet once the page has loaded. The tool keeps working, because there was never anywhere else for the work to happen.
Frequently asked questions
What resolution should I choose?
It depends where the image is going. 72 DPI matches screen resolution and produces a page around 595 by 842 pixels for A4 — fine for a web preview or an email. 150 DPI doubles that to roughly 1240 by 1754 and is the sensible default: text stays crisp when zoomed and the files remain manageable. 300 DPI is the standard for print and gives about 2480 by 3508 pixels per A4 page, which is what a printer or a designer will ask for. Higher is not better if you do not need it — the files get large quickly and nothing on screen looks different.
Should I pick JPG or PNG?
JPG for anything containing photographs or scans, PNG for pages that are mostly text, diagrams or line art. JPEG compression works by discarding detail the eye is unlikely to notice, which is ideal for photographs and visibly bad at sharp black-on-white edges — it leaves faint smudges around letterforms known as ringing artefacts. PNG is lossless, so text stays exactly as rendered, at the cost of a considerably larger file for a photo-heavy page.
Why is the text slightly soft compared to the PDF?
Because a PDF stores text as vector outlines that are redrawn at whatever size you view them, while an image is a fixed grid of pixels. Converting to an image locks the page to one resolution, and any zooming past that point enlarges pixels rather than redrawing letters. This is inherent to the format change, not a flaw in the conversion. If sharpness at any size matters, keep the PDF — or convert at 300 DPI, which is dense enough that most zooming still looks clean.
Can I convert just a few pages?
Yes. Switch to selected pages and enter numbers and ranges — 1-3, 7, 12 works. This is worth doing on a long document even when you eventually want everything, because rendering is the slow part and a 200-page file at 300 DPI is a lot of pixels to hold at once. Doing it in batches is kinder to your browser than one enormous run.
Why do I get a ZIP instead of separate images?
Browsers deliberately block a page from starting many downloads at once — it is a pattern used abusively, so after the first file or two the browser either prompts or silently refuses. Bundling everything into a single archive is the only reliable way to hand you twenty images. A single page downloads directly as one image, with no archive involved.
Does this work on a scanned PDF?
Yes, and it is straightforward — a scanned PDF already contains images, so converting it is closer to extraction than rendering. What the tool will not do is turn the picture of text back into selectable text; that requires optical character recognition, which is a different job. You will get faithful pictures of the pages, exactly as they appear.
Is there a file size or page limit?
No fixed limit, because there is no server to impose one. The real constraint is your device's memory: each page is rendered onto a canvas before being encoded, and an A4 page at 300 DPI occupies roughly 35 MB while it is being drawn, regardless of how small the finished JPEG is. Pages are rendered one at a time and released immediately, so long documents work — they just take a while. If a tab struggles, drop to 150 DPI or convert in batches.
Is my PDF uploaded anywhere?
No. The document is read, rendered and encoded entirely inside your browser using pdf.js, the same rendering engine Firefox uses to display PDFs natively. Nothing is transmitted, stored or logged, and closing the tab discards everything. This matters more for PDFs than for almost any other file type — contracts, medical letters, bank statements, passports and signed agreements are overwhelmingly what people convert, and a server-side converter receives all of it.
