Pi2PDF workshop notes

Plain-language notes from Pi2PDF.com on in-browser PDF tools, limits, and what stays on your device.

From a photo of an invoice to a spreadsheet

The exact Pi2PDF path from a phone photo to rows in Excel, including the 8-page OCR cap and what to check before you trust a total.

What each Pi2PDF tool is for — and when to skip it

A practical map of the PDF, QR, design, and Dev Utils tools on Pi2PDF.com, including the jobs they do not do.

How in-browser PDF conversion works — and where it stops

What happens when you drop a PDF on Pi2PDF.com, which libraries run in the tab, and why some files still need a desktop app.

Compress a PDF without turning the letters into mush

Why high-quality compress on Pi2PDF.com keeps vector text, and when flattening to JPEG is the wrong choice.

When OCR helps a scanned PDF — and when it wastes your time

English print, lighting, and why Pi2PDF.com OCR will not rescue handwriting or a crooked phone photo.

What “files stay on this device” actually means

File conversion on Pi2PDF.com is local. Ads, counters, and browser speech can still use the network. Here is the line we draw.

Merge, split, or organize: which PDF edit do you want?

A short decision guide for combining files, pulling pages out, or reordering a single PDF on Pi2PDF.com.

Why JSON and regex sit next to PDF tools

Pi2PDF.com includes formatters and encoders because the same “stay in the tab” rule helps when you are debugging a payload, not only a PDF.
