PDF to JPG Converter — Free, Online & Private

No — your PDF file never leaves your device. The conversion runs entirely in your browser using PDF.js, Mozilla's open-source PDF rendering engine. PDF.js reads the file from your local memory, renders each page onto an HTML Canvas, and exports the result as an image — all without any network request for your file. You can even disconnect from the internet after the page loads and the tool will still work.

144 DPI is the recommended default for most uses — it produces clear, sharp images that look great on screen and are suitable for general sharing and document purposes. Use 216 DPI if you need to print the images or read small text. Use 288 DPI for professional print-quality output where every detail matters. For quick previews or thumbnails where file size is a priority, 72 DPI is sufficient. Keep in mind that doubling the DPI multiplies the file size roughly by four.

JPG uses lossy compression and is best for PDFs containing photographs, colorful graphics, or complex visual content. It produces smaller files at the cost of some detail. PNG is lossless — every pixel is preserved exactly — making it the best choice for text-heavy documents, technical diagrams, line drawings, or any page where sharpness and accuracy are essential. WebP is a modern format that delivers better compression than both JPG and PNG with excellent quality. It is supported by all modern browsers and image editors, but older software may not recognize it.

Yes. Select Custom range from the Page Range dropdown and enter your page numbers. Use hyphens for ranges and commas to separate groups — for example, 1-3, 5, 8-10 converts pages 1, 2, 3, 5, 8, 9, and 10. Use First page only to quickly extract the cover page or first slide as an image. Pages are numbered starting from 1.

Yes. After all pages are converted, a Download All as ZIP button appears. Clicking it packs all converted images into a single ZIP archive named after your original PDF file (e.g., document_images.zip). You can also download individual pages at any time by clicking the ⬇ Download button under each page thumbnail — even before the entire document finishes converting.

At high DPI settings, the rendered images are visually identical to the PDF as displayed in a PDF viewer. At lower DPI or JPG quality settings, some fine detail may be lost — particularly small text and thin lines. For text-heavy PDFs, use PNG output to preserve sharpness regardless of DPI setting, since PNG is lossless. For photo-heavy PDFs, high-quality JPG at 144–216 DPI is usually indistinguishable from the original.

There is no hard limit on the number of pages. However, converting a very large document (100+ pages) at high DPI may be slow and memory-intensive on older devices. If you only need a subset of pages, use the Custom range option to convert only what you need. For large batches, convert in groups of 20–30 pages at a time for best performance.

PDF.js can open some password-protected PDFs if the password is user-level (view-only protection). If the PDF requires a password to open, the tool will be unable to process it. Owner-level protections (restrictions on printing or copying) do not prevent conversion since PDF.js renders the visual content directly. If you need to convert a locked PDF, use Alfreto's Unlock PDF tool first to remove the password protection.

The tool works in all modern browsers: Google Chrome, Microsoft Edge, Mozilla Firefox, and Safari. No plugins, extensions, or software installations are required. For best performance with large PDFs, use Chrome or Edge on a desktop computer, as they generally have more efficient JavaScript and Canvas APIs than mobile browsers.

Yes. The tool runs in any modern mobile browser, including Safari on iOS and Chrome on Android. For large or complex PDFs, a desktop browser is recommended since phones have less RAM and slower CPUs, which can make high-DPI conversion slow or cause memory issues with very long documents.
