"Best PDF tool" depends on the job. A merger that works for slide decks may fail on encrypted bank statements. Below is a practical shortlist mapped to real tasks on PixelPDF—all runnable in the browser with local processing for core utilities.
Everyday editing & assembly
- Merge PDF — board packs, rental applications, coursework submissions.
- Split PDF — extract exhibits or break archives for email.
- Reorder PDF Pages — fix scanner order without re-scanning.
- Remove PDF Pages — drop blanks and duplicates before sharing.
Conversion without desktop Office
- PDF to Word — editable DOCX when text is selectable or OCR applies.
- Word to PDF — send contracts reviewers cannot edit.
- PDF to Excel — rescue tables trapped in statements.
- Image to PDF — turn phone photos into one document.
Size, delivery, and security
- Compress PDF — email-ready sizes with tunable quality.
- Protect PDF — password before external sharing.
- Watermark PDF — mark drafts CONFIDENTIAL.
- Sign PDF — lightweight signature placement (not qualified e-sign).
How to choose in one minute
Ask: Do I need assembly, conversion, size reduction, or protection? Pick one primary tool, validate output, then chain utilities (merge → compress → protect) instead of hunting for a mythical do-everything app. Read the browser vs desktop guide if compliance is a concern.
