GSC, media, PDF, and color tools

One hundred new browser-local pages thicken thin families: Search Console CTR and query helpers under GSC, pixel and barcode math in Media, pdf-lib metadata and page tools, OKLCH and palette helpers in Color, plus schedule, identity, protocol, security, and encoding entries. Start here when you know the job, not the route name.

Batch DQ adds another hundred Toolcore tools aimed at families that were thin compared with Math or Writing: GSC CTR math and export helpers, media pixel and barcode calculators, PDF metadata operations, and color palette helpers—plus tracking format checks and HTTP header parsers. Fun was intentionally excluded from this batch.

GSC — CTR, queries, and striking distance

CTR calculator and CTR target clicks — quick math from pasted clicks and impressions.
Query normalize, dedupe, and filter — clean export lines before analysis.
Striking distance flag — highlight queries between positions 4 and 10. Pair with insights scanner for full export workflows.

PDF operations and media math

Read PDF metadata, set author, and page size read — real pdf-lib work on uploaded files.
Video frame count, favicon sizes, and barcode quiet zone — planning math without uploads.

Color, schedule, and identity

OKLCH chroma shift, WCAG contrast ratio, and tetradic palette — perceptual and accessibility helpers.
Date difference, ISO week number, and epoch to date — calendar math in the browser.
ISBN-13 format, SWIFT/BIC format, and NHS number format — shape checks only, not live registry lookup.

Protocol, encoding, and checksum demos

CSP header parse, URL query parse, and User-Agent parse — debug traces from curl or DevTools.
Base32 encode, quoted-printable decode, and FNV-1a hash demo — teaching aids, not production crypto.

Common use cases

Normalize Search Console query exports, compute CTR gaps, and filter striking-distance rows before pasting into spreadsheets.
Estimate video frames, favicon export sizes, and barcode quiet zones without leaving the browser.
Set PDF author metadata, read page sizes, or check ISBN-13 and SWIFT BIC format before lookup elsewhere.

Common mistakes to avoid

Treating GSC math as live Search Console data
CTR and striking-distance pages work on numbers you paste—they do not connect to your Google account.
Treating format checks as live lookups
Identity pages confirm shape only—they do not query carrier or registry databases.
Using hash demos for security decisions
Checksum and FNV-style demos illustrate algorithms—they are not audited cryptography.

FAQ

Which categories grew in Batch DQ?

This batch adds GSC hub helpers (10 pages), 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.
