PDF to JPG vs PNG: which image format is better?

Choose JPG for smaller photo-heavy pages or PNG for lossless screenshots, forms, diagrams and text-heavy content.

JPG and PNG compared

Feature	JPG	PNG
Compression	Lossy; discards some visual detail to reduce size	Lossless; preserves exported pixel values
Typical file size	Usually smaller for scans and photographs	Often larger, especially for photo-heavy pages
Sharp text and lines	Can show compression artefacts	Usually cleaner for screenshots, forms and diagrams
Transparency	Not supported; the tool uses a white background	Supported by the format
Best general use	Email, previews, photo scans and smaller downloads	UI screenshots, line art, text and lossless archiving of the rendered page

Both formats contain pixels. Once a PDF page has been rendered as an image, searchable text, selectable text, links and vector scaling are not preserved inside that image file. Keep the source PDF whenever those features matter.

Choose the format by page content

Scanned photograph or brochure: JPG usually gives a practical balance of detail and size.
Application form or text-heavy page: PNG avoids JPG ringing around sharp characters and lines.
Software screenshot: PNG generally preserves interface edges and small labels better.
Quick sharing preview: JPG is often easier when attachment size matters.
Page requiring transparency: choose PNG, although most PDF pages render against an opaque background.

Standard, high or very-high resolution

Resolution controls the number of output pixels, not the amount of detail present in the source. Standard is faster and uses less memory. High is the balanced default for reading and normal sharing. Very high is useful for zooming or print preparation, but it increases memory use and output size.

For JPG, the Smaller, Balanced and Maximum settings control compression quality. Maximum does not create detail that the PDF lacks; it simply preserves more of the rendered pixels and produces a larger file.

How to convert PDF pages to JPG or PNG

Open PDF to JPG / PNG and select your PDF.
Enter the first and last page to convert.
Choose JPG or PNG.
Select a resolution. If using JPG, choose the required quality.
Start conversion and leave the tab open while pages render.
A single page downloads as an image; multiple pages download together as a ZIP.

Convert selected PDF pages

Render up to 60 pages per batch directly in your browser.

Browser limits and troubleshooting

The tool limits one batch to 60 pages to protect browser memory. Very-high resolution multiplies the pixel area of every rendered page, so a shorter range may be necessary on phones or low-memory computers.

Problem	What to try
Text looks blurred	Choose PNG or increase the resolution; also check whether the original PDF already contains a low-resolution scan.
Files are too large	Use JPG with Balanced quality or lower the resolution.
The browser slows down	Convert a smaller page range, choose Standard resolution and close unused tabs.
The PDF will not open	It may be encrypted or invalid. Verify it in a trusted PDF reader.
Several images downloaded as ZIP	This is expected and prevents the browser from prompting separately for every page.

Rendering is not image extraction

This tool uses PDF.js to draw the complete visible page—text, vectors, images and layout—onto a browser canvas. It does not extract the original image objects stored inside the PDF. The output therefore represents the whole page as it appears at the selected resolution.
