Upload the PDF file and the converter renders each page as a separate JPEG file. By default each page becomes its own image; the result is bundled as a ZIP archive ready to download.
What DPI does the JPEG render at?
+
Default 150 DPI (good for screen viewing and most print). Advanced options expose 72 (web thumbnail), 150 (default), 300 (print quality), 600 (high-quality archival). Higher DPI = sharper images but larger JPEG files.
Can I extract just specific pages of PDF as JPEG?
+
Yes — the page-range option accepts inputs like `1-5`, `1,3,5`, or `all` to pick which pages of the PDF get rendered to JPEG. Useful when only a chapter or appendix of a long PDF is needed.
Will the JPEG preserve PDF text searchability?
+
No — rasterizing PDF to JPEG turns text into pixels. If you need searchable output, keep the PDF as a PDF and use a text-extraction tool instead. Image output (JPEG) is for visual display or further image processing.
What about transparent backgrounds in the JPEG?
+
PNG JPEG preserves the PDF page background as transparent if the source page has no fill (rare). JPG JPEG cannot store transparency — pages render onto a white background. For transparent output target PNG, TIFF, or WebP.
How long does PDF to JPEG take for a 100-page document?
+
About 30-90 seconds for a 100-page PDF → JPEG at 150 DPI. Higher DPI doubles or triples the time. Premium users get more parallel workers — 100 pages typically renders in under 30 seconds for them.
What is the file size of a typical JPEG page?
+
A 150-DPI JPEG of an A4 page is 200-800 KB (PNG) or 50-150 KB (JPG quality 85). Multiply by page count to size the ZIP — a 100-page PDF to PNG bundle is typically 30-80 MB.
Can I merge all PDF pages into one tall JPEG image?
+
Not in the basic flow — each page becomes its own JPEG. To produce a single stitched image, download the ZIP, then use /image-merge/ to vertically concatenate the per-page JPEG files.
Is my PDF private during JPEG conversion?
+
Yes — same privacy model: isolated workers, automatic deletion within minutes, no human review.
Will images embedded in the PDF appear correctly in the JPEG?
+
Yes — embedded JPGs, PNGs, and inline graphics inside the PDF are rendered into the JPEG at the page DPI. The page renderer treats them like every other page element.
Can I convert just the first page of a PDF as a JPEG thumbnail?
+
Yes — set the page-range option to `1` and the converter produces a single JPEG file (not a ZIP). Useful for generating cover thumbnails for a PDF library.
Why does my JPEG look pixelated when zoomed in?
+
You're rasterizing vector content into pixels — zoom amplifies the rasterization. If you need infinite-zoom output, target SVG (where the PDF contains vectors); for sharper rasters, bump DPI to 300 or 600 in advanced options.
