How to Convert a PDF to JPG
How to turn PDF pages into JPG or PNG images at the right resolution, including single pages, whole documents, and batches. Covers DPI, JPG vs PNG, avoiding blurry output, and how to go back again.
TL;DR
- Converting a PDF to JPG renders each page as a picture. It is the right move for slides, thumbnails, and social posts — and the wrong move if you still need selectable text.
- Free way: PDF to JPG renders pages with PDF.js in your browser at 1x, 2x, or 3x scale, then downloads them individually or as a ZIP. Nothing is uploaded.
- Scale is the setting that matters: 1x is roughly 96 dpi (screen), 2x roughly 192 dpi (most uses), 3x roughly 288 dpi (print and OCR).
- Choose PNG rather than JPG when the page is text, tables, or line art — JPG smears sharp edges. JPG is fine for photographic pages and makes smaller files.
- Blurry output almost always means the scale was too low. Re-render at 2x or 3x rather than upscaling the image afterwards.
- Going the other way, Image to PDF rebuilds a PDF from images — though the text will not come back as text.
- Acrobat, macOS Preview, and Smallpdf can all do this too; comparison below.
Turning a PDF into images is one of those tasks with a clear right answer once you know two things: what resolution you need, and whether the page is mostly text or mostly photographs. Get those right and the output looks exactly like the original. Get them wrong and you end up with something blurry, enormous, or both. This guide covers both decisions, the step-by-step conversion, and the cases where converting is the wrong idea entirely.
When Converting to Images Is the Right Move
- Dropping a page into a slide deck, a document, or an email body where a PDF attachment would be awkward.
- Posting a page to social media or a platform that accepts images but not PDFs.
- Generating thumbnails or previews of a document for a website or an app.
- Preparing pages for OCR — a high-resolution PNG is often the cleanest input for text recognition.
- Sharing a page you would rather the recipient did not easily copy text out of, with the caveat that this only slows people down rather than preventing anything.
The flip side is worth stating plainly. An image of a page is not a document: the text is no longer selectable or searchable, screen readers cannot read it, links no longer work, and it will not print as crisply as the vector original at large sizes. If you are converting only to make a file smaller, compressing the PDF is almost always the better answer.
Choosing a Scale (Resolution)
| Scale | Approx. DPI | A4 page pixel size | Use it for |
|---|---|---|---|
| 1x | ~96 dpi | Around 794 x 1123 | Web thumbnails, on-screen previews, quick reference images |
| 2x | ~192 dpi | Around 1588 x 2246 | The sensible default — slides, documents, images that may be printed casually |
| 3x | ~288 dpi | Around 2382 x 3369 | Print-quality output, OCR source images, anything that will be zoomed into |
Higher is not automatically better. Rendering at 3x takes noticeably longer on a long document and produces files several times larger, which matters if you are converting a hundred pages. Pick the scale for the destination, and if the result is not sharp enough, re-render rather than enlarging the image afterwards — upscaling cannot add detail that was never drawn.
JPG or PNG?
| JPG | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| File size | Much smaller | Larger, often several times so |
| Text and line art | Visible fuzz around sharp edges | Perfectly crisp |
| Photographs | Excellent | Excellent, but wastefully large |
| Best for | Photographic pages, web use, large batches where size matters | Document pages, diagrams, tables, and anything heading for OCR |
The short version: a page of black text on white is the worst possible case for JPG, and PNG handles it perfectly. A full-bleed photograph is the case JPG was designed for. If you are unsure, PNG is the safer default and you can always compress the images afterwards.
How to Convert a PDF to JPG — Step by Step
- 1
Open the PDF to JPG tool
Go to PDF to JPG on WeConvertIt. Pages are rendered with PDF.js — the same engine behind the PDF viewer in Firefox — entirely inside your browser.
- 2
Drop in one PDF or a whole batch
Drag your files onto the upload area. Every page of every file will be rendered with the same settings and labelled by its source document.
- 3
Pick the output format
JPG for photographic pages and small files, PNG for text, tables, and diagrams where sharp edges matter.
- 4
Pick a scale
1x for screen use, 2x for most purposes, 3x for print or OCR. When in doubt, start at 2x and check one page before committing to a long document.
- 5
Render and download
Click Render, then download individual pages from their thumbnails or take everything as a single ZIP.
Converting Pages for OCR
If the goal is to get text out of a scanned PDF, the image quality you feed the recognition engine matters more than the engine itself. Render at 3x as PNG, so that letter edges stay sharp and JPG artefacts do not confuse character recognition, then run the pages through Image to Text. For a PDF that already contains real text — one exported from a word processor rather than scanned — skip the images entirely and use PDF to Word, which extracts the text directly and gives a far better result.
Conversion Tools Compared
| Tool | Cost | Uploads your file? | Notes |
|---|---|---|---|
| PDF to JPG (WeConvertIt) | Free, no account | No — runs in your browser | JPG or PNG at 1x, 2x, or 3x, batch conversion, per-page or ZIP download. Scale presets rather than an exact DPI box. |
| Adobe Acrobat Pro | Paid subscription | No — desktop app | Exact DPI control, colour space management, TIFF and other professional formats, and per-page export settings. The right tool for prepress work. |
| macOS Preview | Free, built in | No — local app | Export as JPEG with a resolution field. Straightforward for a single page; awkward for a whole document since it exports one page at a time. |
| Smallpdf / iLovePDF | Free tier, then paid | Yes — server-side | Easy and effective, with the usual trade-off that your document is processed on their servers and free use is limited per day. |
| ImageMagick / pdftoppm | Free, open source | No — local | Exact DPI, page ranges, and output naming, fully scriptable. The best option for automating large volumes. |
Going the Other Way
To rebuild a PDF from images, Image to PDF places one image per page and produces a normal PDF file. It is genuinely useful for turning phone photographs of paperwork into a single document — but be aware that a PDF made from images contains no real text, so it cannot be searched, selected, or filled as a form. If you started from a text PDF, converted it to images, and converted back, you have lost all of that; keep the original whenever you can. From there you can still merge it with other documents, compress it — image-built PDFs shrink a lot — or password protect it.
Frequently Asked Questions
How do I convert a PDF to JPG?
Open PDF to JPG, drop in your PDF, choose JPG and a scale of 1x, 2x, or 3x, and click Render. Every page is drawn as an image in your browser, and you can download pages individually or take the whole document as a ZIP. No account and no upload are involved.
How do I convert a PDF to JPG for free?
PDF to JPG is free with no sign-up, no watermark, and no daily cap. On a Mac, Preview can also export pages as JPEG with a DPI setting, and on Windows the Snipping Tool handles a quick one-off grab, though neither is convenient for a long document.
How do I convert just one page of a PDF to JPG?
Render the document and download only the page you want — each rendered page has its own download button, so there is no need to extract it first. If you would rather work with a single-page file, Split PDF can pull out the page and you can convert that on its own.
What resolution should I use when converting PDF to JPG?
Match the scale to the destination. 1x gives roughly 96 dpi, which is fine for a web thumbnail or an on-screen preview. 2x gives roughly 192 dpi and is the sensible default for slides, documents, and anything that might be printed casually. 3x gives roughly 288 dpi, which is what you want for proper printing or before running OCR. Higher scales take longer to render and produce much larger files, so there is no benefit in always choosing 3x.
Should I convert PDF pages to JPG or PNG?
PNG is lossless and keeps text, tables, and line art crisp, at the cost of a larger file. JPG uses lossy compression, which produces much smaller files and looks fine on photographic pages but leaves visible fuzz around sharp black-on-white text. For a typical document page, PNG usually looks noticeably better; for a page that is mostly photography, JPG is the practical choice. Our image format comparison covers the trade-off in more depth.
Why is my converted JPG blurry?
Almost always because it was rendered at too low a scale. Rendering at 1x and then enlarging the image cannot recover detail that was never drawn — go back and re-render the page at 2x or 3x instead. The other cause is JPG compression on a text-heavy page, which produces a soft halo around letters; switching the output to PNG fixes that.
How do I convert several PDFs to images at once?
Drop them all into PDF to JPG together. Every page of every file renders with the same format and scale, each labelled with its source file, and the ZIP download bundles the entire batch.
Can I convert JPG back to PDF?
Yes — Image to PDF assembles images into a PDF, one page per image. Be clear about what that gives you, though: the pages will be pictures of text, not text. A round trip from PDF to JPG and back produces a document you cannot search, select, or copy from. If you need the words back, run the images through Image to Text to OCR them.
Does converting a PDF to JPG lose quality?
It loses capability more than fidelity. At 2x or 3x the image looks very close to the original on screen, but the page stops being a document: text is no longer selectable or searchable, hyperlinks stop working, form fields disappear, and it no longer scales cleanly to arbitrary zoom levels the way vector content does. Convert when you specifically want an image, and keep the PDF when you want a document.
