What happens when you convert a PDF to PNG
When you convert a PDF to PNG, you're turning a document file into an image file. A PNG is a picture — each page of your PDF becomes a separate image that you can view, edit in photo software, or insert into presentations and web pages. The text inside stays readable, but it's no longer selectable or searchable the way it is in a PDF.
This matters because it changes what you can do with the file afterward. You can't copy text out of a PNG the way you can from a PDF. But you gain the ability to crop, resize, add drawings, or use the image in places that don't accept PDF files — like some social media platforms or older document systems.
The conversion process itself is straightforward. You have three main routes: use free online converters, use software already on your computer, or use dedicated conversion tools. Each has different trade-offs around speed, privacy, and what you need to install.
Key Takeaways
- Converting a PDF to PNG turns each page into a separate image file, making the text no longer searchable or editable.
- Online converters are fastest but require uploading your file to someone else's server, which matters if the PDF contains sensitive information.
- Windows and Mac both have built-in tools that can convert PDFs without installing anything new or uploading files.
- The quality of the PNG depends on the resolution you choose during conversion — higher resolution means larger file size but sharper text and images.
Using free online converters
Online PDF-to-PNG converters like Smallpdf, ILovePDF, and CloudConvert work in your web browser. You upload your PDF, choose which pages you want to convert, select your resolution, and download the PNG files. Most are genuinely free for one or two conversions per day, though they'll try to sell you a paid plan.
The main advantage is speed — you don't install anything, and the conversion happens in seconds. The main disadvantage is privacy. Your PDF file goes to someone else's server, gets converted there, and then you download it. If your PDF contains bank statements, medical records, or anything you wouldn't email to a stranger, this route isn't safe. Even if the company deletes files after an hour, you're still sending sensitive information across the internet to a third party.
If you use an online converter, pick one that explicitly states it deletes files automatically and uses HTTPS (you'll see a padlock icon in your browser's address bar). Smallpdf and ILovePDF both state they delete files after an hour. Don't use converters that ask you to create an account or that keep your files in a "history" folder.
Converting on Windows using built-in tools
Windows 10 and 11 can convert PDFs to PNG without any extra software. Open your PDF in Microsoft Edge (the browser that comes with Windows), then press Ctrl+P to open the print menu. In the "Printer" dropdown, select "Print to PDF" — but instead, look for "Microsoft Print to Image" or a similar option depending on your Windows version.
Select "Microsoft Print to Image" from the printer list, then click "Print." A dialog will open asking where to save the file and what format you want. Change the format from PDF to PNG, choose your location, and click "Save." Windows will convert the page to a PNG image. If your PDF has multiple pages, you'll need to repeat this for each page, or use the page range option in the print dialog to do several at once.
This method keeps your file on your computer the entire time — nothing leaves your machine. The downside is that it's slower than an online converter if you have many pages, and the quality depends on your printer settings. If the text looks blurry, go back to the print dialog and look for a "Quality" or "DPI" setting — increase it to 300 DPI or higher for sharper results.
Converting on Mac using Preview
Mac's built-in Preview app can open PDFs and export them as PNG files. Open your PDF in Preview (it's in your Applications folder, or press Command+Space and type "Preview"). Once the PDF is open, go to File menu, then "Export As." A dialog will appear asking what format you want. Change the format dropdown from PDF to PNG.
Choose where to save the file and what resolution you want — the "Quartz Filter" dropdown usually has options like "Reduce File Size" or "High Quality." For text-heavy PDFs, pick "High Quality" or leave it on default. Click "Save," and Preview will convert that page to PNG. If your PDF has multiple pages, Preview will ask whether you want to export all pages or just the current one. Choose "All" if you want every page as a separate PNG file.
Like the Windows method, this keeps everything on your computer. Preview is slower than online converters for large files, but the quality is usually good and you have full control over the resolution.
Choosing the right resolution for your PNG
Resolution is measured in DPI (dots per inch) or pixels per inch. For PDFs with mostly text, 150 to 200 DPI is usually enough — the text will be clear and readable. For PDFs with images, small text, or graphics you want to edit later, use 300 DPI. Going higher than 300 DPI rarely makes a visible difference but makes your file much larger.
If you're converting for web use — to post on a website or social media — 72 to 96 DPI is standard and keeps file sizes small. If you're converting to print the PNG later or to edit it in photo software, use 300 DPI. Most online converters let you pick the DPI before conversion. Windows and Mac's built-in tools usually have quality settings in their print or export dialogs.
Test with one page first. Convert it at your chosen resolution, open the PNG, and zoom in to check if the text is sharp enough for what you need. If it's blurry, redo the conversion at a higher DPI. If it looks good but the file is huge, try a lower DPI next time.
Handling multi-page PDFs
When you convert a multi-page PDF, each page becomes a separate PNG file. Online converters usually create a ZIP folder containing all the PNGs, which you download and unzip on your computer. Windows and Mac's built-in tools also create separate files — one PNG per page — and ask you where to save them.
The files are usually named automatically: page-1.png, page-2.png, and so on. If you want to rename them or organize them into folders, do that after conversion. Some online converters let you select which pages to convert before you start, which is useful if you only need pages 5 through 10 from a 50-page document.
When to use each method
| Method | Best for | Trade-off |
|---|---|---|
| Online converter (Smallpdf, ILovePDF) | Quick conversions of non-sensitive files | File uploaded to third-party server; slower for large PDFs |
| Windows built-in (Print to Image) | Sensitive files; no software to install | Slower for multi-page PDFs; requires repeating steps per page |
| Mac Preview | Sensitive files; can batch-convert all pages at once | Slower than online converters; Mac only |
Use an online converter if your PDF is public information and you want the fastest result. Use your computer's built-in tools if the PDF contains anything you wouldn't want on someone else's server — bank details, medical information, personal documents, or work files marked confidential.
Frequently Asked Questions
Will the PNG look exactly like the PDF?
Yes, visually. The PNG will be a picture of what the PDF looks like on screen. Text will be readable, images will show, and colors will match. The difference is that you can't select or copy the text in a PNG the way you can in a PDF — it's now part of an image.
What if my PDF is password-protected?
You'll need to open it and enter the password first. Online converters won't accept a locked PDF. Open it in your PDF reader (Adobe Reader, Preview, or your browser), enter the password, then save it as an unlocked copy. After that, you can convert it using any method.
Can I convert just one page from a multi-page PDF?
Yes. Online converters usually have a page range option where you can type "5" or "5-10" to convert only those pages. With Windows Print to Image, use the page range field in the print dialog. With Mac Preview, you can delete the pages you don't want before exporting, or export all pages and delete the PNGs you don't need afterward.
Why is my PNG file so large?
High resolution creates larger files. If you converted at 300 DPI and the file is huge, try converting again at 150 DPI. PNG files are also larger than JPG files for the same image — if file size is critical, some online converters let you choose JPG instead, though PNG is better for text because it doesn't blur.
Can I convert a PNG back to a PDF?
Yes, but the text won't be searchable or editable — it will just be an image inside a PDF. If you need an editable document, work from the original PDF instead. If you just need to combine multiple PNGs into one PDF, online converters and free tools like LibreOffice can do that.
