PDF Hauv Paus — Cov Lus Teb Sai
Dab Tsi Yog PDF?
PDF stands for Portable Document Format — a file type introduced by Adobe in 1993 that renders identically on every device. Unlike Word or Google Docs files, a PDF preserves fonts, layout, images, and vector graphics regardless of where it's opened, which is why contracts, receipts, tax forms, and official documents are nearly always shared as PDFs.
Vim Li Cas PDFs Nyuaj Kho?
PDFs were designed as a presentation format, not an editing format. The original text is stored as positioned glyphs with embedded font subsets, not flowing paragraphs, so changing a word can require re-layout, font substitution, and byte-level content-stream surgery. PDF Edit solves this by detecting text, parsing fonts, and reflowing edits with the closest matching typeface — no re-save required.
Puas Yog PDFs Ruaj Ntseg?
A PDF by itself is not private — text in a PDF can be copied, searched, and extracted. To truly secure a PDF you need two things: AES-256 password protection (so only the recipient can open it) and real redaction (deleting sensitive characters from the file rather than painting a black box over them). PDF Edit supports both.
Koj Puas Tuaj Yeem Kho PDF Scanned?
Yog, nrog OCR. Ib qho PDF scanned technically yog PDF-wrapped image — tsis muaj txheej ntawv kom kho ncaj qha. Siv lub cuab yeej OCR Region los xaiv ib thaj tsam, hloov nws ua cov ntawv kho tau, thiab tom qab ntawd kho raws li ib txwm.
