PDF kepada JPG Soalan Lazim Penukaran

How do I convert PDF pages to JPG images?

Upload the PDF file and the converter renders each page as a separate JPG file. By default each page becomes its own image; the result is bundled as a ZIP archive ready for download.

What DPI does the JPG render at?

Default 150 DPI (good for screen viewing and most print). The advanced options expose 72 (web thumbnail), 150 (default), 300 (print quality), 600 (high-quality archival). Higher DPI yields sharper JPG images but quadratically larger files.

Can I extract just specific pages of PDF as JPG?

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 JPG. Useful when only a chapter or appendix of a long PDF is needed as images.

Will the JPG preserve PDF text searchability?

No — rasterizing PDF to JPG turns text into pixels. If you need searchable output, keep the PDF as a PDF and use a text-extraction tool instead. Image output (JPG) is for visual display or further image processing.

What about transparent backgrounds in the JPG?

PNG JPG preserves the PDF page background as transparent if the source page has no fill (rare in real-world PDF). JPG JPG cannot store transparency — pages render onto a white background. For transparent output, target PNG, TIFF, or WebP.

How long does PDF to JPG take for a 100-page document?

About 30-90 seconds for a 100-page PDF -> JPG 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 JPG page?

A 150-DPI JPG 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 JPG image?

Not in the basic flow — each page becomes its own JPG. To produce a single stitched image, download the ZIP, then use /image-merge/ to vertically concatenate the per-page JPG files into one tall result.

Is my PDF private during JPG conversion?

Yes — same privacy model: isolated workers, automatic deletion within minutes, no human review.

Will images embedded inside the PDF appear correctly in the JPG?

Yes — embedded JPGs, PNGs, and inline graphics inside the PDF are rendered into the JPG 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 JPG thumbnail?

Yes — set the page-range option to `1` and the converter produces a single JPG file (not a ZIP). Useful for generating cover thumbnails for a PDF library or content-management system.

Why does my JPG look pixelated when I zoom in?

You are rasterizing vector content into a fixed pixel grid — zooming amplifies the rasterization. If you need infinite-zoom output, target SVG (where the PDF carries vectors); for sharper rasters, bump DPI to 300 or 600 in the advanced options.
