Tool guides updated and salary tax calculation corrected
Added reproducible examples, clarified OG and speech behavior, and fixed the default tax allowance and top-bracket display.

This update improves both tool results and the guidance around them, so users can see what each tool supports and how to check its output.
Salary tax corrections
The salary tax estimator now starts with a 60,000-baht allowance, matching its label. The marginal-bracket display is corrected for taxable income above five million baht. A worked example shows annual salary of 600,000 baht and allowances of 60,000 producing estimated tax of 21,500 baht before withholding credits.
The tool applies salary expense rules, not every income category. It does not verify allowance eligibility or calculate a balance due or refund. Check Revenue Department rules for the relevant tax year before filing.
Failed exchange rates are not presented as zero
The currency converter displays a dash when a valid rate has not loaded and avoids stale results after switching the base currency. Its guidance now identifies the data as daily reference rates from ExchangeRate-API, rather than real-time trading quotes.
Guidance that matches the controls
Added input/expected-result examples and limitations to ten tools, including JSON, YAML, CSV, QR and image tools. OG Preview is now clearly described as a manually entered mockup; it does not fetch metadata from a URL.
Speech notices and the privacy policy explain that browsers may use external speech services. All three published Blog topics now include practical steps and primary references in both languages.
If a result looks wrong, send the page URL, reproduction steps and a non-sensitive example through Contact.
October 27 follow-up: guidance and search metadata
Updated the main descriptions for all 107 tools in Thai and English, and corrected 59 guides whose controls or capabilities did not match the interface. Examples include Word Counter, Base64, Reading Time and the invoice-number generator. Added reproducible examples and clearer limits for modeled results.
Titles, descriptions, canonical URLs and language alternates now match the individual pages. Share metadata was completed and unsupported review ratings were removed. These improvements do not guarantee search rankings or advertising approval.
The salary estimator now identifies its section 33 social-security model for 2026–2028 and no longer treats named fund contributions as automatically eligible deductions. Users must verify their actual eligibility and figures.
