PDF に CSV 変換に関するよくある質問
How do I convert a PDF file to CSV?
+
Upload your PDF file using the picker above and the converter detects the source type and runs the PDF -> CSV pipeline. The result downloads automatically when conversion completes; no account is needed for one-off conversions.
Is the PDF to CSV converter free?
+
Yes — basic PDF -> CSV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a PDF file can I convert to CSV?
+
Free accounts: up to 100 MB per PDF file. Premium: typically 1 GB per file, depending on the PDF source type. Very large files get split into chunks server-side when the CSV format permits.
Will conversion change the content of my PDF?
+
Conversion preserves every piece of information that both PDF and CSV can represent. Features the CSV format cannot store (vector data in raster output, formulas in plain-text output, embedded fonts in image output) are rasterized or stripped — the result page flags any feature loss explicitly.
Can I convert many PDF files to CSV at once?
+
Yes — drop multiple PDF files into the upload zone and they queue in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the PDF to CSV converter work on phones / tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end without an app.
Which browsers does the PDF to CSV converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses a plain `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers convert PDF to CSV successfully.
Are my PDF files kept private?
+
Yes — uploaded PDF files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
What if the CSV download does not start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download you can re-trigger from the result page without re-uploading the PDF.
How long does PDF to CSV conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. The server-side pipeline runs on dedicated workers — your laptop CPU is not the bottleneck.
Do I need to install software to convert PDF to CSV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your PDF, wait, download the CSV.
Can I convert PDF to CSV without an account?
+
Yes for one-off conversions. Sign up free for batch history, server-side file storage, and higher conversion limits. Premium adds parallel workers, bigger file caps, and removes ads.
