GSC, media, PDF, and color tools

Another hundred browser-local pages thicken thin families: new GSC rank and export helpers, media retina and banner math, pdf-lib rotate and metadata tools, WCAG contrast and palette helpers, plus schedule, identity, protocol, security, and encoding entries. Fun was excluded from this batch.

Batch DR adds another hundred Toolcore tools with new GSC slugs (not duplicating Batch DQ CTR pages), media and PDF helpers with -dr suffixes, color contrast and palette math, plus schedule, identity, protocol, security, and encoding entries—all client-side.

GSC — rank change, exports, and CTR bands

Rank change and page-one gap — position delta math from pasted exports.
Rows to JSON, sort A–Z, and CTR band label — clean and analyze query lists locally.
Pair with insights scanner and Batch DQ CTR calculator for full export workflows.

PDF operations and media math

Rotate all pages, set creator, and count pages — pdf-lib on uploaded files.
Retina scale, OG image size, and video duration — pixel and timeline planning.

Color, schedule, and identity

Contrast ratio quick, triadic palette, and hex luminance — WCAG and palette helpers.
Fiscal year start, weekday count, and VIN checksum — date and identifier shape checks (no registry lookup).

Protocol, encoding, and security demos

Cache-Control parse, Set-Cookie parse, and Location parse — split HTTP response headers.
Hex decode, Morse encode, and Adler-32 demo — encoding and checksum illustrations (not production crypto).

Common use cases

Track GSC position deltas, sort query exports, and convert rows to JSON before analysis workflows.
Plan retina icon sizes, OG image dimensions, and video downscale targets without leaving the browser.
Rotate PDF pages, set metadata fields, or validate VIN and routing number checksums locally.

Common mistakes to avoid

Treating GSC math as live Search Console data
Rank change and CTR band pages work on numbers you paste—they do not connect to your Google account.
Treating format checks as live lookups
Identity pages confirm shape and checksum only—they do not query carrier or registry databases.
Using hash demos for security decisions
MD5 and simplified HMAC demos illustrate algorithms—they are not audited cryptography.

FAQ

Which categories grew in Batch DR?

This batch adds GSC hub helpers (10 new slugs), Media (15), PDF (12), Color (13), plus Schedule, Identity, Protocol, Security, and Encoding entries—all client-side. Fun quota was zero.

Do PDF tools upload files?

No. PDF pages load files in your browser with pdf-lib, same as the existing PDF hub—nothing is sent to a server.

Can agents prefill these tools?

Single text fields often accept q or qb. PDF uploads and multi-field number or date tools open without URL prefill.
