What PDF to JPG does
This converter renders every page of a PDF as a JPG image at twice screen resolution (about 144 dpi, or 1,190 × 1,684 pixels for an A4 page) and lets you download each page as a separate file. It is the standard way to get a PDF page into a place that only accepts images — a social post, a slide, an image field on a form, a messaging app preview — or to lift a diagram out of a report. Rendering is done by PDF.js, the same engine Firefox uses to display PDFs, and runs entirely in your browser.
Choosing a quality setting
| Setting | JPEG quality | Approx. size (A4 text page) | Best for |
|---|---|---|---|
| Low | 60% | 80–150 KB | Thumbnails, chat previews |
| Medium | 80% | 150–300 KB | Web pages, email, slides |
| High | 92% | 300–600 KB | Default — visually lossless for most content |
| Maximum | 100% | 0.8–1.5 MB | Archival copies; rarely worth the size |
JPEG quality above 92% adds size much faster than it adds visible detail. Pages with large flat areas (forms, text on white) compress very efficiently at any setting; photographic pages benefit most from the higher levels.
JPG vs PNG for PDF pages
JPG is a lossy format designed for photographs. On a page of black text it introduces faint halos around letters that are invisible at normal size but show up when zoomed in or printed large. PNG is lossless and renders text perfectly, at the cost of larger files for photographic content. Use this tool when the destination requires JPG or when file size matters; use PDF to PNG for screenshots of text, diagrams with sharp lines, or anything you will edit further.
What is lost in conversion
- Text becomes pixels. The image cannot be searched or copied. Run OCR on it if you need the text back.
- Vector graphics are rasterized. Logos and charts are sharp at 144 dpi but will pixelate if enlarged much beyond A4.
- Links, form fields and annotations are flattened into the picture (visible if they had an appearance, gone if they did not).
- Transparency is composited onto white; JPG has no alpha channel.
- Colour is converted to sRGB. CMYK print files will look slightly different, as they would in any screen viewer.
Common uses
- Posting a flyer, menu or certificate to Instagram, Facebook or LINE, which do not accept PDFs.
- Inserting a PDF page into PowerPoint, Google Slides or a Word document as a picture.
- Uploading a signed form to a website whose upload field only allows image files.
- Creating a preview thumbnail of a document for a website or product listing.
- Extracting a chart or figure from a paper for a presentation.
Tips
- Convert only the pages you need: use Extract Pages first on long documents to save time and downloads.
- If the output looks blurry in its destination, the destination is probably upscaling. Crop to the region you need rather than enlarging the whole page.
- For print-quality output (300 dpi), export from the original application instead; this tool targets screen use.
- Browsers may ask permission to download multiple files; allow it for multi-page PDFs.
