PDF Tools Toolora’s PDF category covers everyday document tasks: shrink files, merge or split pages, convert to images/text, add watermarks, and edit in the browser when the library supports it. Choose by intent: compress for size limits; merge/split for page organization; convert when you need JPG/text/HTML; protect/unlock for passwords; editor when you need markup. Most PDF tools process files in your browser with PDF-lib. Always check each tool’s page for size limits and what it actually changes (for example, compress rewrites streams — it does not re-encode photos). Image Tools Image tools run on an HTML canvas in your browser for compress, resize, crop, convert, and related edits. Start here: Image Compressor for file size; Image Resizer for pixel dimensions; format converters when you need WebP/JPG/PNG. Transparency and animation are not always preserved — read each tool’s limitations before batch work. Calculator Tools Calculator tools evaluate standard formulas in your browser: loans/EMI, interest, BMI, percentages, tips, margins, and more. Each page documents the formula it uses. Results are estimates — not financial, medical, or legal advice. Date & Time Tools Work with dates and times locally: differences, add/subtract days, business-day counts, leap checks, week numbers, and live countdown/stopwatch. Calculations use your browser’s local timezone unless a tool says otherwise. Converter Tools Converters apply fixed factors (or temperature formulas) in your browser. Use multi-unit hubs for several units at once, or single-pair pages for a focused URL. Empty or non-numeric input shows an error instead of a fake zero result. Business Tools Business tools help with everyday planning math and simple document helpers. Treat outputs as drafts and verify against your accounting rules. CV & Career Tools CV and career tools help you assemble resume and letter drafts from form fields. Review and customize before sending applications. QR & Barcode Tools Create QR codes for URLs, Wi‑Fi, and text, or barcodes for product-style values. Download the image when the UI offers it. Text Tools Text tools count, transform, and clean strings locally. Unicode is handled by the browser’s JavaScript engine. Security & Password Tools Security utilities include password generation and developer-oriented hash/SSL helpers. Read each page’s privacy note — CSR generation and hashing typically stay in-browser. Developer Tools Developer tools format, validate, minify, and encode common data formats. Invalid JSON/XML shows parse errors instead of silent corruption. SEO Tools SEO tools help you draft meta tags, robots rules, and sitemap snippets, or inspect URLs via server checks where noted. These utilities do not guarantee rankings — they support correct technical markup and checks. Color Tools Color tools convert and explore hex, RGB, and HSL values, build palettes/gradients, and check contrast — all in the browser. File Tools File tools cover archives, hashes, and type checks. Prefer the tool page privacy section to see whether processing is local or server-assisted. Web Utility Tools Web utilities inspect request metadata or fetch public URLs you provide. Tools that contact remote hosts will send the URL you enter to the server. Generator Tools Generators create placeholder or random values in your browser. Useful for mocks and drafts — not a substitute for audited cryptographic systems when security is critical.
