True text editing vs visual PDF editors: which do you need?
Some PDF editors rewrite the exact text you target. Most rebuild the whole page. We ran the same one-number edit through both and diffed the results against the original.
We changed $224.91 to $1,050.00 on a rental invoice with both tools. pdfblah rewrote that number and nothing else; the file stayed 14.1 KB. Stirling PDF's Text Editor rebuilt the page: the file grew to 21.2 KB, a ZIP code moved, and both timestamps were shoved into their clock icons. Their own editor warns it's "not ideal for tables or multi-column layouts", and that's what an invoice is.
pdfblah compare.What pdfblah does
Load several files, stack edits that apply to all of them (replace, redact, scrub, watermarks, page numbers, stamps, page ops, metadata, merge), preview every step live, download. Fonts it can't reproduce are refused by name; you can ask it to substitute a similar standard font, and the report records the swap.
When to use a visual editor
Scans (no text layer means nothing to find; you need OCR first) and redesigns (moving paragraphs, resizing headings, swapping images need a canvas).
