PDF to Image Converter – Convert PDF to JPG or PNG Free
1. Choose a PDF
The password stays in this browser and is passed directly to PDF.js.
2. Choose pages

3. Download images
Convert PDF pages in three steps
- Choose a PDF. The browser parses it and creates small page previews without uploading the file.
- Choose pages and quality. Select all pages, tick individual pages, or enter a range. Then choose PNG or JPG and a real DPI value.
- Convert and download. Download one image from its card or package selected results in one ZIP.
PNG versus JPG
| Format | Best for | Background | Trade-off |
|---|---|---|---|
| PNG | Text, diagrams, screenshots, transparency | White or transparent where the PDF permits | Lossless and often larger |
| JPG | Photos, scans, smaller shares | Always white | Adjustable lossy compression |
Resolution examples
PDF.js renders at scale = DPI ÷ 72. Pixel size equals the physical page size in inches multiplied by the chosen DPI.
| Page and DPI | Approximate output | Recommendation |
|---|---|---|
| Typical page at 96 DPI | Shown live before conversion | Fast previews and mobile use |
| A4 at 150 DPI | 1241 × 1754 px | Screen sharing and clear text |
| A4 at 300 DPI | 2481 × 3507 px | Detailed printing |
| US Letter at 300 DPI | 2550 × 3300 px | Detailed printing |
Common uses and limitations
Use complete-page conversion for document previews, social posts, slide images, scanned-page archiving, and inserting a PDF page into software that accepts images. Use extraction mode when you need embedded photos or scans without the surrounding page text and vector graphics.
Page conversion produces a raster image, so text is no longer editable. Annotations, form appearances, optional layers, fonts, transparency, and colors are rendered according to browser and PDF.js capabilities; exact print color profiles and every interactive PDF feature are not guaranteed. Image extraction returns decoded raster image objects and may produce several images, no images, or reused image data depending on how the PDF was authored.
Troubleshooting
- Out of memory: choose fewer pages, lower the DPI, close other tabs, or use a desktop browser.
- Blank or unusual output: try a white PNG background or JPG; some optional layers and unsupported PDF features render differently between viewers.
- No extracted images: the page may contain vector artwork or a single rendered page stream rather than separate embedded raster images.
- Password rejected: retry the document password; no password recovery is performed.
PDF to image converter FAQs
Are my PDF files uploaded?
No. The PDF bytes are read and processed locally by PDF.js in your browser. They are not transmitted to or stored by Starlight Tools and are cleared when you reset or close the page.
Can I convert individual PDF pages?
Yes. Choose Selected pages and tick individual page previews, or enter a range such as 1-3, 5, 8-10 before conversion.
Should I choose PNG or JPG?
Choose PNG for text, diagrams, transparency, and lossless output. Choose JPG for photos or smaller files; JPG always uses a white background.
How do I convert a PDF at 300 DPI?
Choose the 300 DPI resolution preset. The converter uses a PDF.js scale of DPI divided by 72 and shows predicted pixel dimensions before conversion.
What PDF size can the converter handle?
There is no fixed server limit because processing is local, but your device memory is the practical limit. Large page counts, oversized pages, 300 DPI output, and image-heavy PDFs can exhaust memory; convert a smaller page range or lower the DPI if warned.
Can I convert a password-protected PDF?
Yes, if you know the password. The converter asks for it locally when PDF.js detects encryption and reports an incorrect password without discarding your selected file or settings.
Does the PDF converter work on mobile?
Yes in current mobile browsers with JavaScript, Web Workers, Canvas, Blob, and WebAssembly support. Mobile devices have tighter memory limits, so use selected pages and 96 or 150 DPI for large PDFs.
How do ZIP downloads work?
After conversion, select the outputs you need and choose Download selected as ZIP. The ZIP uses the source PDF name and zero-padded page filenames. You can also download one image from its preview card.
What is the difference between page conversion and image extraction?
Page conversion renders the complete visible page, including text and graphics. Extraction finds embedded raster image objects and exports those images without the surrounding page layout; it does not turn page text or vector artwork into separate images.
Does text remain editable after conversion?
No. Complete-page conversion rasterizes text, annotations, and graphics into pixels. Use a PDF text extraction or OCR tool if you need editable text.
