PDF to PNG
Turn all pages of a PDF, or only the ones you pick, into lossless PNGs with sharp text. Opens password-locked PDFs too.
When PNG is the better choice for PDF pages
Pick PNG when the page is mostly text, lines or flat colour. That covers notes, slides, invoices, charts, maps, forms and certificates. PNG compression is lossless, so every pixel the PDF engine draws ends up in the file exactly as drawn. JPG, by contrast, saves space by blurring fine detail, and the first place you notice it is the soft halo around black text on white paper.
Pick JPG instead when the page is a photo or a scan of a photo, or when an upload form has a tight KB limit. For those, use PDF to JPG.
| Page type | Better format | Why |
|---|---|---|
| Typed notes, slides, code, tables | PNG | Edges of letters stay crisp |
| Charts, diagrams, floor plans | PNG | Thin lines and flat colours compress well without loss |
| Certificates with a logo or seal | PNG | Small details stay readable when zoomed |
| Photos, brochures, scanned pages | JPG | Much smaller files with no visible difference |
| Upload forms with a KB limit | JPG | Size can be dialled down with quality |
How to convert PDF to PNG
- Drop one PDF into the box above, or click to browse.
- If it is locked, type the password in Password (locked PDFs only).
- Optional: list the pages you want in Pages (optional), such as 2 or 1-3, 5. Leave it empty for every page.
- Choose a Resolution: Low (72 DPI), Medium (144 DPI, the default), High (216 DPI) or Print (288 DPI). There’s no quality slider, because PNG is always lossless.
- The pages render on their own. The status line shows progress, such as “Rendering page 2 of 9”.
- Download one page, or click Download all (ZIP). Files are named after your PDF and keep their real page number, such as notes-page-7.png.
Change the resolution or the page list at any time and the pages are drawn again. Picking only the pages you need also keeps Print resolution quick, since a 30-page PDF at 288 DPI is a lot of pixels.
Resolution and file size
A PDF page is measured in points, 72 to the inch. The resolution setting decides how many pixels each point becomes. For an A4 page (595 × 842 points):
| Setting | DPI | A4 page in pixels | Total pixels |
|---|---|---|---|
| Low | 72 | 595 × 842 | 0.5 million |
| Medium | 144 | 1191 × 1684 | 2 million |
| High | 216 | 1786 × 2526 | 4.5 million |
| 288 | 2381 × 3368 | 8 million |
Each step up adds far more pixels than the last, and PNG file size grows with them, so High and Print files get large fast. Pages with photos grow the most, because photos don’t compress well without loss.
For slides and screen reading, Medium is enough. Use High or Print when you plan to crop a small part of the page, such as one chart, and still want it sharp.
Why your files stay private
The PDF is read by your browser and drawn with PDF.js (opens in new tab), Mozilla’s open-source PDF engine. The PNGs are created in the same tab. Nothing is sent to our server, so there’s no upload wait and no copy left behind. Upload-based converters such as Smallpdf state that files are deleted an hour after processing, and FreeConvert says 8 hours. Here, there’s nothing to delete.
That matters for documents like salary slips, offer letters, mark sheets and bank statements. Password-locked PDFs open here too: type the password in the Password box and PDF.js uses it inside your tab to decrypt the file. The password is never sent anywhere, and a wrong one shows “That password is wrong. Check capitals and try again.”
After converting
- Need a smaller file? The image compressor turns PNGs into compact WebP files, or into JPG if you pick it.
- The form wants JPG? Run the PNG through PNG to JPG, or convert the PDF straight to JPG.
- Only one chart or table? Crop the image to keep just that part.
Limitations
- White background, not transparent. Pages render on white, the way they look in a PDF reader.
- One PDF at a time. Use the Pages box to skip pages you don’t need.
- No selectable text. The PNG is a picture of the page.
- Large files. PNG at Print resolution is big. Use Medium if you’re converting a long PDF on a phone.
- You need the password for a locked PDF. The tool can’t remove or guess one.
Key facts
- PNG uses lossless compression and supports transparency. JPEG has no alpha channel. (MDN (opens in new tab))
- PDF.js is a general-purpose, web-standards-based platform for parsing and rendering PDFs, maintained by Mozilla and contributors. (PDF.js (opens in new tab))
- Smallpdf states that converted files are deleted from its servers after one hour. (Smallpdf (opens in new tab), as of October 2026)
- FreeConvert states that uploaded files are deleted automatically after 8 hours. (FreeConvert (opens in new tab), as of October 2026)
FAQ
PDF to PNG FAQs
Is PDF to PNG better than PDF to JPG?
PNG is better for text, charts and line drawings, and JPG is better for photos and small files. PNG is lossless, so letters and thin lines stay sharp. JPG blurs fine detail to save space, which shows around text. If an upload form has a KB limit, JPG is easier to fit under it.
Does PDF to PNG lose quality?
No quality is lost in the PNG step, because PNG is lossless. Sharpness depends on the resolution you choose. At 72 DPI small text can look rough because there are few pixels, while 216 or 288 DPI keeps it crisp. Pick the resolution first, and the PNG keeps exactly what was drawn.
What resolution should I use for PDF to PNG?
Use 144 DPI (Medium) for screens, slides and sharing. An A4 page becomes 1191 × 1684 pixels. Use 216 DPI for small print and 288 DPI for printing or for cropping one chart out of a page. Higher settings make much larger PNG files, so avoid Print for long PDFs on a phone.
Why are my PNG files so large?
PNG keeps every pixel without loss, so it is larger than JPG, especially for pages with photos. Resolution adds to it: Print draws about 8 million pixels for an A4 page. Choose Medium, or run the PNGs through the image compressor to turn them into WebP or JPG when you need smaller files.
Can I get a transparent background?
No. Pages are drawn on a white background, the same way a PDF reader shows them. If you need a transparent logo from a PDF, convert the page, crop the logo, and remove the background in an image editor. Most PDF pages are designed on white anyway, so this rarely matters.
Is my PDF uploaded anywhere?
No, your PDF is never uploaded. It is read and drawn inside your browser using Mozilla’s PDF.js, and the PNGs are made in the same tab. You can test it: convert one file, turn off your internet, and convert another. It still works because there is no server step.
Can I convert a password-protected PDF to PNG?
Yes. Drop the PDF in and the tool tells you it is locked. Type the password in the Password (locked PDFs only) box and the pages render as PNGs. The password is used only inside your browser to open the file and is never uploaded. If it is wrong, you’ll see a message asking you to check capitals and try again.
How do I convert many PDF pages at once?
Drop the PDF in and every page converts automatically, or type a list such as 1-10 in Pages to convert only those. When there is more than one page, a Download all (ZIP) button saves every PNG in one ZIP file. The tool takes one PDF at a time, so for several PDFs, convert and download each one in turn.
