FAQ
- What is the most common PDF version? PDF 1.7 is the most widely used version today, as it is the basis for ISO 32000-1 and is supported by nearly all modern software.
- Is PDF 2.0 widely supported? PDF 2.0 was standardized in 2017, but full reader support is still rolling out. Most readers handle it gracefully but may fall back to 1.7 features.
- Is my file uploaded anywhere? No — the check happens entirely in your browser; the PDF never leaves your device.
