How do I convert PDF pages to WebP images?

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

What DPI does the WebP render at?

Default 150 DPI (good for screen viewing and most print). Advanced options expose 72 (web thumbnail), 150 (default), 300 (print), 600 (archival). Higher DPI = sharper images but larger WebP files.

Can I extract just specific pages of PDF as WebP?

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 WebP. Useful when only a chapter or appendix of a long PDF is needed.

Will the WebP preserve PDF text searchability?

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

What about transparent backgrounds in the WebP?

PNG and WebP WebP preserve a transparent page background if the source page has no fill (rare). JPG WebP cannot store transparency — pages render onto a white background. For transparency, target PNG, WebP, or TIFF.

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

About 30-90 seconds for a 100-page PDF -> WebP at 150 DPI. Higher DPI doubles or triples the time. Pro users get more parallel workers — 100 pages typically renders in under 30 seconds for them.

What is the file size of a typical WebP page?

A 150-DPI WebP of an A4 page is 200-800 KB (PNG), 60-200 KB (WebP), 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 WebP image?

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

Is my PDF private during WebP conversion?

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

Will images embedded in the PDF appear correctly in the WebP?

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

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

Why does my WebP look pixelated when zoomed in?

You are rasterizing vector content into pixels — zoom amplifies the rasterization. If you need infinite-zoom output, target SVG when the PDF contains vectors; for sharper rasters, bump DPI to 300 or 600 in advanced options.
