Frequently asked questions
Common problems and fixes
- The output has empty or missing text
Why: the source pages were a scan or an image — there is no text layer to convert.
Fix: run the OCR PDF tool on the file first to add a searchable text layer, then convert again.
- Tables and columns come out jumbled
Why: a PDF stores positions on a page, not rows and cells, so designed layouts are reconstructed approximately.
Fix: for data you need in a spreadsheet, use the Extract Tables tool instead — it is built for that job.
- Fonts look slightly different in the converted file
Why: a PDF embeds glyph shapes rather than font families, so the closest available font is substituted.
Fix: expect near-identical text flow rather than pixel-perfect type; fix fonts in the target app if exactness matters.
Who uses PNG to PDF?

- Office teams — reusing content from reports and statements without retyping it by hand.
- Anyone handling confidential documents — the conversion runs in your browser, so contracts and financial files never leave your device.
