To convert a PDF to PNG, drop the file into the converter above, choose 72, 150 or 300 DPI, and either keep all pages or enter a range like 2-4, 7. Click Convert and each page is saved as a lossless PNG image named document-page-1.png and so on. Download them one at a time or as a single ZIP.
How to use the PDF to PNG tool
- 1
Drop in the PDF
Drag your PDF onto the converter or tap to browse. Encrypted files prompt for their password, which stays on your device.
- 2
Set the resolution
Select 72, 150 (default) or 300 DPI. Since PNG has no quality slider, DPI is the main control over sharpness and file size.
- 3
Select pages
Keep all pages, or enter specific ones using commas and hyphens, for example 1, 3-5, 12.
- 4
Convert and save
Click Convert, then download each PNG separately or all of them together in one ZIP archive.
When lossless PNG is the better choice for PDF pages
PNG compresses images without throwing away any pixel data. What the PDF renderer draws is exactly what ends up in the file. For pages built from text, tables, line art, schematics, spreadsheets and charts, that matters: letters keep clean edges, thin lines stay thin, and flat colour areas stay perfectly flat, with none of the faint blocky noise that lossy compression can add around high-contrast edges.
That makes PNG a good fit for slides you want to drop into documentation, screenshots of a contract clause for a presentation, diagrams from a technical manual, or any page you might edit later in an image editor. Re-saving a PNG does not degrade it, while every re-save of a JPG can lose a little more detail.
The cost is file size. A page full of photographs can produce a PNG several times larger than the equivalent JPG. If your PDF is mainly photos or a scanned magazine, PDF to JPG is usually the more practical choice.
Resolution, file size and the white background
Because PNG output has no quality setting, resolution is the lever you control. 72 DPI is fine for a small preview, 150 DPI reads comfortably on most screens, and 300 DPI is what you want for printing or for zooming into fine print. Going from 150 to 300 DPI doubles the width and height of each image, so expect files to grow considerably.
One point that surprises people: PNG supports transparency, but converted PDF pages are rendered on a white page, the same way they look in a PDF viewer. You get an opaque image of the full page, not a cut-out of individual elements. If you need a transparent logo, export it from the original design file rather than from the PDF.
Private by design: your PDF stays in the browser
Pages are drawn by PDF.js, the open-source PDF engine from Mozilla, running locally in your browser tab. The document is not transmitted to Krawly, there is no copy on a server waiting to be deleted, and closing the tab clears it from memory.
This is useful when the PDF contains things you would not paste into a random website: an invoice with your client's details, a medical letter, an internal design spec. You get the same result as a desktop app without installing anything, and it is free with no watermark or signup.
Tips for the best results
- Use 300 DPI when the PNG will be printed or when small labels in a diagram must stay legible.
- For photo-heavy pages, PDF to JPG gives much smaller files with little visible difference.
- Convert only the pages you need with a range like 3-5; it is quicker and saves memory on phones.
- PNGs are a good intermediate format if you plan to annotate or crop the pages in an image editor.
Frequently asked questions
How do I convert a PDF to PNG?
Drop the PDF into the converter on this page, choose a DPI, select all pages or a range, and click Convert. Each page is rendered as a lossless PNG; for high quality images, choose 300 DPI. You can download the images separately or as one ZIP. No account is needed and the PDF is processed in your browser.
Is PDF to PNG better quality than PDF to JPG?
At the same DPI, PNG preserves every rendered pixel exactly, while JPG uses lossy compression. For text, line art and diagrams PNG looks crisper, especially when zoomed in. For photographs the visible difference is small and JPG files are much smaller, so the better choice depends on what the page contains.
Will the PNG images have a transparent background?
No. PDF pages are rendered onto a white background, just as they appear in a PDF reader, so each PNG is an opaque image of the whole page. PNG can store transparency, but a rendered page does not have transparent areas to keep.
Why are my PNG files so large?
PNG is lossless, so it cannot discard detail to save space, and pages with photos or gradients compress poorly. Higher DPI adds more pixels too. Try 150 DPI instead of 300, or use PDF to JPG for photo-heavy pages if file size matters more than perfect edges.
Can I convert a password-protected PDF to PNG?
Yes, as long as you know the password. The converter asks for it when it detects an encrypted file and uses it only inside your browser to open the document. It does not crack or remove passwords.
Are my files uploaded when I convert PDF to PNG?
No. The PDF is opened and rendered locally using PDF.js in your browser. Nothing is uploaded to Krawly's servers and nothing is kept after you close the tab. Only the converter's own program files are loaded from the website.
Private by design. Every Krawly converter runs inside your browser using JavaScript and WebAssembly. Your files are not uploaded, stored or seen by anyone — when you close the tab, they are gone.
