How to convert a PDF to JPG
- Drop the PDF on the box above. The page count and page size appear straight away.
- Choose JPG for scans and photos or PNG for crisp text and diagrams.
- Pick a resolution. 150 DPI suits most uses; the note under the menu shows the exact pixel size of page 1.
- Optionally type a page range such as
2-4, 9. Leave it empty to convert everything. - Click Convert to images, then save individual pages or the whole set as a ZIP.
Which DPI to use for PDF to JPG
A PDF page has no pixels of its own — it is measured in points (1/72 inch). The DPI you pick decides how many pixels each inch of the page becomes, so it controls sharpness and file size together. Pixel size is page width in inches × DPI.
| DPI | A4 page (210×297 mm) | US Letter (8.5×11 in) | Typical JPG size, text page | Use it for |
|---|---|---|---|---|
| 72 | 595 × 842 px | 612 × 792 px | 50–120 KB | Thumbnails, quick previews |
| 96 | 794 × 1123 px | 816 × 1056 px | 80–180 KB | Showing a page in chat or email at normal size |
| 150 | 1240 × 1754 px | 1275 × 1650 px | 150–400 KB | Default: reading on a phone or laptop, form uploads |
| 200 | 1654 × 2339 px | 1700 × 2200 px | 250–650 KB | Small print, footnotes, tables you need to zoom into |
| 300 | 2480 × 3508 px | 2550 × 3300 px | 0.5–1.5 MB | Printing, OCR, slides projected on large screens |
| 600 | 4961 × 7016 px | 5100 × 6600 px | 2–5 MB | Line art, engineering drawings, archiving |
Sizes are for a mostly-text page at quality 92; a page full of photos can be two to three times larger. The rule of thumb: 150 for screens, 300 for print. Going above the resolution of the original scan adds file size but no detail — a PDF scanned at 200 DPI does not get sharper at 600.
JPG vs PNG for PDF pages
- JPG uses lossy compression tuned for photographs. It is the right choice for scanned documents (which are already photos of paper), brochures and slides with pictures. At quality 85–92 the artefacts around text are hard to see.
- PNG is lossless. For a born-digital page of black text on white, PNG at 150 DPI is often both sharper and not much larger than JPG, because PNG compresses large flat areas very well. Use it for diagrams, code, spreadsheets and anything you will run through OCR.
- WebP is 25–35% smaller than JPG at similar quality and fine for websites, but some government portals and older apps only accept JPG.
Worked examples
Uploading an Aadhaar, PAN or marksheet PDF where a form wants JPG
Many Indian portals (exam applications, passport, bank KYC) accept only JPG and cap the size at 100–500 KB. Convert just the needed page, for example 1, at 150 DPI, JPG quality 75. An A4 page comes out at 1240 × 1754 px and typically 120–300 KB. If the portal asks for less, run the JPG through the image compressor with a target size, or crop out just the card with the image cropper.
Posting a PDF flyer on Instagram
Instagram does not accept PDFs. Convert the page at 200 DPI as JPG, then crop to 4:5 (1080 × 1350) so the feed does not trim it.
Sharing one slide from a report
Convert only that page as PNG at 150 DPI. Chat apps show an image inline, while a PDF shows up as a file icon people have to open.
Troubleshooting
- A page renders blank or slowly: very large pages at 600 DPI can exceed the browser canvas limit (around 16,000 px on a side or 268 million pixels). The tool warns you and suggests a lower DPI.
- Fonts look wrong: some PDFs rely on fonts that are not embedded. PDF.js substitutes a close match; the layout stays the same.
- Colours look duller than in Acrobat: CMYK print PDFs are converted to screen RGB, which cannot show every print colour.
- Need the opposite direction? Use image to PDF, or combine several PDFs first with the PDF merger.
FAQ
Is my PDF uploaded to a server?
No. The PDF is opened with PDF.js inside your browser and each page is drawn to a canvas on your device. The file is never uploaded, which makes it safe for bank statements, ID cards and contracts.
What DPI should I choose when converting PDF to JPG?
150 DPI is a good default for reading on screen and sharing. Use 200 to 300 DPI when the image will be printed or you need to zoom into small text, and 600 DPI only for fine line art or archiving. 72 to 96 DPI is enough for thumbnails and previews.
Can I convert only some pages?
Yes. Type a page range such as 1-3, 5, 8- in the Pages field. Leave it empty to convert every page.
Should I choose JPG or PNG?
JPG is smaller and ideal for scanned pages and photos. PNG is lossless, so it keeps text and line drawings perfectly crisp but produces larger files. For a page that is mostly text, PNG at 150 DPI often looks sharper than JPG at 300 DPI.
Does it work with password-protected PDFs?
Yes, if you know the password. The tool asks for it and unlocks the file locally. It cannot remove or guess an unknown password.
How do I make the JPG small enough for an online form?
Convert at 100 to 150 DPI with JPG quality around 75, which usually gives an A4 page between 100 and 300 KB. If a form needs something smaller, such as under 100 KB, pass the JPG through an image compressor afterwards.
