PDF että WebP Usein kysytyt kysymykset konversioista
How do I convert PDF pages into 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 is 150 DPI (good for screen viewing and most print). The advanced options expose 72 (web thumbnail), 150 (default), 300 (print quality), and 600 (high-quality archival). Higher DPI = sharper WebP but larger 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 render 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 into WebP turns text into pixels. If you need searchable output, keep the source as PDF and use a text-extraction tool. Image output (WebP) is for visual display, OCR input, or further image processing.
What about transparent backgrounds in the WebP?
+
PNG WebP preserves a transparent background where the PDF page has no fill (rare). JPG WebP cannot store transparency — pages render onto white. For transparent output target PNG, TIFF, or WebP.
How long does PDF to WebP take for a 100-page document?
+
About 30 to 90 seconds for a 100-page PDF → WebP at 150 DPI. Higher DPI doubles or triples the time. Premium users get more parallel workers — 100 pages typically renders in under 30 seconds on that tier.
What is the file size of a typical WebP page?
+
A 150-DPI WebP of an A4 page is 200-800 KB (PNG) or 50-150 KB (JPG quality 85). Multiply by page count to size the bundle — a 100-page PDF to PNG bundle is typically 30-80 MB.
Can I merge all PDF pages into a single tall WebP image?
+
Not in the basic flow — each page becomes its own WebP. To produce a 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, no third-party access to the PDF or the rendered WebP output.
Will images embedded in the PDF appear correctly in the WebP?
+
Yes — embedded JPGs, PNGs, and inline graphics inside the PDF are rendered into the WebP at the chosen page DPI. The page renderer treats them like every other page element; no quality is lost beyond rasterization.
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 or eBook catalog.
Why does my WebP look pixelated when zoomed in?
+
You are rasterizing vector content into pixels — zoom amplifies the rasterization grid. For infinite-zoom output, target SVG (where the PDF contains vectors). For sharper rasters at zoom, bump DPI to 300 or 600 in the advanced options.
PDF-tiedostot säilyttävät muotoilun kaikissa laitteissa ja käyttöjärjestelmissä, mikä tekee niistä ihanteellisia jaettaessa tiedostoja, joiden pitää näyttää samalta kaikkialla.
