PDF → PNG

Export PDF pages as lossless PNG images, sharp enough for text, diagrams and screenshots.

How to convert PDF to PNG

Choose a PDF.
Pick a resolution: Screen, Standard or Print.
Keep All pages, or choose Choose pages and type the page numbers.
Press Export images, then download each PNG or all of them as a ZIP.

Options

Resolution: Screen is 72 DPI, Standard is 150 DPI and Print is 300 DPI. Doubling the DPI gives four times the pixels, and the PNG grows with it.
Pages: All pages exports every page. Choose pages takes numbers and ranges such as "1, 3-5"; the button stays disabled until the list is valid.
No quality setting: PNG is lossless, so there is nothing to trade. Resolution is the only control that changes file size.

What you get

One PNG per selected page, named after the PDF with the page number, such as slides-004.png.
Download the images one at a time or all of them as a ZIP.
Pixels are stored without lossy compression, so text edges and thin lines have no JPEG artefacts.
Pages are drawn on a white background. Transparency, vectors, links and selectable text are not kept.
The pixel size of each image matches the page at the chosen DPI, so a Letter page at 150 DPI is about 1275 × 1650 pixels.

Limits

Each image is limited to 16 megapixels on a computer or Android device and 4 megapixels on iPhone and iPad. A4 at 300 DPI is about 8.7 megapixels, so use Standard on a phone.
Every selected page is checked against the limit before the first image is written. If one page is too large, nothing is exported.
PNG files of photo-heavy pages are several times larger than JPG. Use PDF to JPG for those.
A password-protected PDF must be unlocked first.
Resolutions above 300 DPI are not offered.

Check the result

Deckle checks that the number of images matches the pages you chose, that each PNG opens and that each has the expected pixel size. Zoom in on a page with small text to confirm the resolution is enough for your use.

Questions

Should I use PNG or JPG for PDF pages?

PNG for pages of text, charts, diagrams or UI, where sharp edges matter. JPG for pages that are mostly photographs, where PNG files get large.

Can I get a PNG with a transparent background?

No. Every page is drawn on white, because a PDF page has no background of its own and most pages would otherwise come out unreadable.

Which resolution is best for slides or documentation?

Standard (150 DPI) suits slides, wikis and email. Print (300 DPI) suits printing or cropping a detail out of the page.

Can I export a single page?

Yes. Choose Choose pages and type one number, such as "4".

Is my PDF uploaded?

No. The pages are rendered and saved as PNG in your browser.

Why are my PNG files so large?

PNG stores every pixel without lossy compression. A page full of photographs at 300 DPI can be several megabytes. Choose Standard, or use PDF to JPG for photo pages.

Is the text in the PNG still selectable?

No. The PNG is a picture of the page. Use PDF to text if you need the words themselves.
