常见问题
Are my files uploaded to a server?
No. PDF processing happens locally in your browser with pdf-lib, so your files never leave your device and nothing is stored.
How is the PDF rendered?
Pages are rendered locally with Mozilla's pdf.js library (loaded only on this page), then exported from a canvas as PNG or JPG. Nothing is uploaded.
Why is the first conversion a little slow?
The renderer (pdf.js) loads on first use. After that, conversions are fast.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
