PDF to PNG Converter
Turn PDF pages into sharp PNG images with no compression artefacts — ideal for diagrams, screenshots, slides and documents you want to edit or annotate.
PNG is selected for you. Switch Format to JPG if you need much smaller files for an upload form.
When PNG is better than JPG
PNG stores every pixel exactly, so thin lines, small text and flat colours stay crisp. JPG saves space by blurring fine detail slightly, which shows up as fuzzy edges around text and lines.
That makes PNG the better choice for charts, forms, slides, maps and anything you plan to crop, mark up or place in another document. For photos or strict KB limits, JPG is usually the better fit.
Choosing a resolution for PNG pages
The resolution decides how many pixels each page gets. At 72 DPI an A4 page becomes about 595 × 842 pixels, which is enough to view on a phone or paste into a chat. At 150 DPI the same page is about 1240 × 1754 pixels, a good balance for reading on a laptop or adding to a presentation. At 300 DPI it is about 2480 × 3508 pixels, the size to use when you want to print the page or zoom into small print.
Because PNG is lossless, file size grows quickly with resolution. A text page at 150 DPI is often a few hundred kilobytes, while a full-colour page at 300 DPI can be several megabytes. If a page will only be viewed on screen, the standard setting is usually all you need.
Getting clean results
Start from the original digital PDF whenever you can. A PDF made directly by a website or an office app has real text and vector shapes, so the PNG comes out sharp at any resolution. A PDF made from a photo or a scan already contains a picture, and converting it to a higher resolution will not add detail that was never there.
Transparent areas are filled with white so pages look the same in every viewer. Each page becomes its own PNG, named after the PDF and the page number, which keeps a set of pages in order when you save them together as a ZIP. Everything is done in your browser, so private documents never leave your device, and you can convert another file straight away without waiting for an upload or a download link.
PNG or JPG?
| PNG | JPG | |
|---|---|---|
| Quality | Lossless, every pixel kept | Small loss, softer edges |
| File size | Larger | Much smaller |
| Best for | Text, diagrams, slides, editing | Photos and upload limits |
| Under a KB limit | Fits by reducing pixels | Fits by lowering quality first |
How to use it
- Choose your PDF.
- Keep All pages, or choose pages such as 1-3.
- Pick a resolution and press Convert.
- Download each PNG, or all pages together as a ZIP.
Tips for sharp PNG images
- Use 150 DPI for screens and 300 DPI only when you need to print or zoom in.
- Convert just the pages you need to keep the download small.
- For a strict KB limit, JPG usually keeps text more readable than PNG.
- Zoom into the preview before you download to check small text.
Frequently asked questions
How do I convert a PDF to PNG?
Add the PDF, keep PNG selected under Format, choose a resolution and press Convert. Each page is saved as its own PNG.
Is PNG better quality than JPG?
Yes. PNG is lossless, so text and lines stay perfectly sharp. The trade-off is a larger file.
Can I convert only one page?
Yes. Choose “Choose pages” and type the page number, or a range like 2-4.
Can I keep each PNG under a KB limit?
Yes, pick a maximum size. Because PNG is lossless, KbSnap fits it by reducing the pixel size, so for tight limits JPG usually keeps text more readable.
Does it work with password-protected PDFs?
No. Remove the password in your PDF viewer first, then add the file again.
Is my PDF uploaded?
No. Pages are rendered and saved as PNG in your browser, on your device.
