Strip image metadata from browser-readable images with local scanning, clean JPEG/PNG/WebP output, privacy-marker checks, and cleanup receipts before sharing.

Resize images online with presets, pixel or percent sizing, fit, contain, cover, format, quality, and size-cap controls for web, email, avatar, and uploads.

Encode online image files into Base64 text, data URLs, JSON-safe strings, embed snippets, and delivery guidance for HTML, CSS, email, or JSON/API handoff.

Extract PDF text with auto native-text fallback, OCR language, page ranges, DPI, page ledger, confidence, readiness checks, and TXT/JSON outputs.

Compress files online as ZIP, TAR, GZ, or Brotli outputs, compare size savings, verify SHA-256 hashes, and split downloads for tight transfer limits.

Estimate PDF compression savings from source structure, profiles, target size, local rewrite limits, and backend readiness checks before handoff.

Merge PDF files in visible queue order with local page-count checks, file and size guards, metadata choice, readiness warnings, and handoff review.

Delete selected PDF pages from one local file with range validation, keep/delete maps, output naming, and signature or accessibility review warnings.

Extract selected PDF pages from one local file with range validation, typed or unique order, page guard checks, manifest rows, and handoff download review.

Add page numbers to a PDF in the browser with page ranges, start value, number style, margins, placement preview, output checks, and handoff review.

Reorder PDF pages from one local file with typed ranges, quick orders, duplicate modes, page guards, manifest exports, readiness checks, and PDF download.

Plan PDF password protection, permission profiles, metadata handling, local structure checks, and engine readiness before encrypting owner-approved files.

Prepare PDF redaction preflight from search terms, page ranges, manual areas, hidden-data cleanup gates, text matches, and handoff evidence before release.

Review damaged PDFs with local structure checks, parser status, rewrite and fresh-page repair modes, warnings, recovery plan, and JSON evidence before handoff.

Rotate PDF pages by selector, orientation, and direction with local output, readiness checks, and a page-by-page rotation map before review.

Stamp a visible typed, drawn, or image signature onto one PDF page, review placement and readiness warnings, and download the locally made PDF before sharing.

Split one PDF into custom ranges, every-page files, or fixed-size packets with local validation, packet guards, manifest checks, and ZIP handoff review.

Review owner-approved PDF unlock readiness with local structure scan, known-password status, authorization gate, and blocked decrypt-engine handoff before processing.
