- No watermark, no file limit
About this tool
PNG is the right format when a PDF page contains text, tables, diagrams or line art. It is lossless, so hard edges stay crisp instead of picking up the soft halos that JPEG compression leaves around black text on white.
Your PDF never leaves your device. Pages are rendered to images by a JavaScript library running in this tab. Nothing is uploaded.
How to use this tool
- Select your PDF and wait for the page thumbnails.
- Tick the pages you want, or leave all unticked for the whole document.
- Choose a resolution. 150 DPI is fine on screen; 300 DPI for printing or detailed inspection.
- Press Convert to PNG and download the image or ZIP.
What the PDF to PNG does
The rendering is identical to the JPG converter — pages are drawn onto a canvas at your chosen resolution. The difference is the encoding: PNG stores pixels exactly as rendered, with no lossy compression.
The trade-off is size. A text-heavy page as PNG is often two to four times the size of the same page as JPG. For screenshots of documents that is usually worth it; for photographic pages it rarely is.
PNG versus JPG for PDF pages
Rendering is identical:
Pixel width = page width in points × DPI ÷ 72
Encoding differs:
JPG — lossy, small files, soft halos around sharp edges
PNG — lossless, larger files, edges stay exact
Typical A4 text page at 150 DPI:
JPG at 90% ≈ 250 KB
PNG ≈ 600 KB to 1 MB
Choose PNG for text and line art, JPG for photographs.
Worked example
Example: a page of tables
| Content | financial tables, black text on white |
| At 200 DPI as JPG | ≈ 380 KB, faint halos on rules and text |
| At 200 DPI as PNG | ≈ 900 KB, edges exact |
For a table that someone needs to read carefully, the larger file is the right choice. For a photograph, the same comparison runs the other way.
What your result means
Larger files are expected. PNG stores every pixel exactly; that is the point of using it.
PNG is the better choice whenever the page is mostly text, tables, forms or diagrams.
The image is still an image. Text is not selectable — use the text extractor if you need the words.
Things to watch out for
- PNG has no quality setting because it is lossless. The only lever on file size is resolution.
- For pages that are photographs, JPG at 90% is visually equivalent and far smaller.
- PNG output from this tool has no transparency — pages are rendered onto white, as they would print.
- At 300 DPI a full-page PNG can exceed 3 MB. Convert in batches for long documents.
- If you need the original embedded images rather than a rendering of the page, use the image extractor.
Limitations of this tool
- Output is a raster image; text is no longer selectable or searchable.
- PNG files are substantially larger than JPG at the same resolution, particularly at 300 DPI.
- Very long documents at high resolution can exhaust browser memory.
- Password-protected PDFs cannot be opened.
Frequently asked questions
Is PNG better than JPG for PDF pages?
For text, tables and line art, yes — edges stay sharp because PNG is lossless. For pages that are mostly photographs, JPG looks the same and produces much smaller files.
Why is there no quality setting?
PNG is lossless, so there is nothing to trade away. Resolution is the only control over file size.
Do the PNGs have transparent backgrounds?
No. Pages are rendered onto white, matching how the page would print.
Why are my files so large?
PNG stores every pixel exactly. At 300 DPI an A4 page is 2480 × 3508 pixels — several megabytes. Reduce the DPI if the files are impractical.
