Webtoolshop — free online tools
Webtoolshop is a collection of practical utilities you run in your web browser: word and character counters, JSON formatters, loan and tax calculators, image and PDF helpers, QR codes, regex labs, and more. Most tools process your input locally on your device—no account and no upload to our servers for those features.
Unlike a bare input box, each tool has its own page with a short guide: what the utility does, step-by-step usage, practical tips, limitations, and FAQs written for that specific tool. That helps you decide whether it fits your task before you paste text, upload a file, or run a calculation.
Browse by category below or use search. Calculators and converters are for quick checks—not professional tax, legal, or medical advice. For questions, see About, Privacy, and Terms.

Bulk Image Compressor
Process many files one after another; each download starts automatically (browser may ask to allow multiple downloads).
WebP Converter
Raster images → PNG, JPEG, or WebP (including GIF — animated GIF uses the first frame only). WebP can be saved as PNG or JPEG.
JPG ↔ PNG
Convert between JPEG and PNG without uploading your file.
HEIC / HEIF → JPG, PNG, or WebP
HEIC decoding works in Safari and some recent Chromium builds; other browsers may show an error. Creating HEIC output is not supported in the browser.

Add two or more files. Use Up / Down to set order. Password-protected PDFs are not supported.
PDF Split
Split one PDF into several files. Each page gives a ZIP of single-page PDFs. Groups uses 1-based page numbers, semicolons separate output files (e.g. 1-3;5;7-9).
PDF Compress
Re-saves your PDF with stream optimization. Works best on some vector-heavy files; scanned books may not shrink much.

CryptoJS algorithms load once from cdnjs (~200 KB). SHA3 needs a modern CryptoJS bundle.
Base64 Encode / Decode
UTF-8 safe — good for Unicode text, not only ASCII.
Regex101-style Lab
JavaScript flavor: matches, groups, and replace preview. For PCRE / full debugger open regex101.com.

About Webtoolshop
Webtoolshop is a small site of free, browser-based utilities: text and writing helpers, calculators, colour tools, image and PDF tasks, and a handful of developer aids. The pages are built so you can open a tool, use it, and leave—no signup wall and no paywall for the features you see on screen.
Every tool URL includes original copy for that utility: an introduction, use cases, numbered steps, practical tips, a “good to know” note about privacy or accuracy, and FAQs that mention the tool by name. We maintain this text in our build pipeline so pages are not empty shells with only a widget—reviewers and visitors see context before they interact with the calculator or converter.
How it works
Most tools run entirely in your tab: your files and pasted text are processed with JavaScript on your device. A few pages call public services (for example translation or DNS lookups); those requests go straight from your browser to the third party, the same way any website would.
Accuracy and responsibility
Calculators and converters are meant for quick checks, not binding financial, tax, legal, or medical decisions. Always verify important numbers with a qualified professional or official source.
Supporting the site
Hosting and domain costs are partly offset by advertising. When Google AdSense is enabled for a build (config/adsense.json at build time), you may see display ads in the marked slots. You can use ad blockers; the tools still work if your browser allows the scripts they rely on.
Feedback
Ideas for new tools, broken behaviour, or partnership notes are welcome via the Contact page and the request / report forms linked in the footer.
Terms of Service
Last updated: May 2026. By using Webtoolshop you agree to these terms.
The service
Webtoolshop provides free browser-based calculators, converters, and utilities as-is. We may change, add, or remove tools without notice. There is no paid subscription for the features shown on the site.
Acceptable use
You agree not to misuse the site: no automated scraping that harms performance, no attempts to break security, no uploading of illegal content, and no use of network tools to harass others or probe systems you do not own or have permission to test.
No professional advice
Calculators (tax, loan, BMI, zakat, prayer times, translation, etc.) are for general information only. They are not tax, legal, medical, or religious rulings. Verify important results with qualified professionals or official sources.
Your content
You are responsible for text, files, and URLs you enter. For tools that run locally, data stays in your browser unless you choose to download or copy output. Tools that call third-party APIs send data under those providers’ terms.
Intellectual property
Webtoolshop branding, layout, and original written content on this site are protected by applicable law. Do not republish large portions of our pages as your own product without permission. Tool output (numbers, converted files, etc.) belongs to you.
Advertising
We may show Google AdSense or similar advertising. Ad partners may use cookies as described in our Privacy Policy.
Disclaimer of warranties
The site and tools are provided “as is” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability.
Limitation of liability
To the fullest extent permitted by law, Webtoolshop and its operators are not liable for indirect, incidental, or consequential damages arising from your use of the site, including loss of data, profits, or business opportunity.
Contact
Questions about these terms: Contact or contact@webtoolshop.com.
Privacy Policy
Last updated: May 2026. This page describes how Webtoolshop handles information when you use the public website.
Who operates this site
Webtoolshop is published as a static website (HTML, CSS, and JavaScript). There is no “log in” database on our hosting for the tools themselves.
Data processed in your browser
Many utilities—image resize or convert, JSON format, PDF merge, password generation, and similar—run only inside your browser. Files you pick from your device are not sent to Webtoolshop’s web host for processing. Data stays in memory until you close the tab or refresh, unless your browser saves drafts or restores a session on its own.
Third-party services
Some tools intentionally contact other providers (examples: public DNS JSON, translation APIs, prayer-time APIs, or a CORS proxy for HTTP checks). Those providers receive whatever URL or text your browser sends them, under their own terms and logging practices. Do not submit secrets, personal identifiers you are not comfortable sharing, or internal-only URLs unless you accept that risk.
Contact and request forms
If you use “Request a tool” or “Report an issue”, your message is delivered through our form provider (for example Web3Forms) to the inbox we configure. That message is subject to the provider’s privacy policy and retention rules, not stored by us on static hosting.
Cookies and advertising
We may use Google AdSense. Google and its partners can use cookies or similar technology to serve and measure ads, including personalised advertising where allowed. See How Google uses cookies in advertising, Google’s Privacy Policy, and Google Ads Settings to control personalisation.
Children
The site is general-purpose. It is not aimed at children under 13, and we do not knowingly collect personal information from them through these tools.
Changes
We may update this policy when the site or its integrations change. The “Last updated” line at the top of this section will move forward when we do.
Contact
Privacy questions: Contact page or contact@webtoolshop.com. See also Terms of Service.
Contact
Use the addresses below for the type of message you are sending. We read everything, but high volume means we cannot always reply the same day.
General & partnerships
Press coverage, link exchanges, billing for services, or anything that is not a bug in a specific tool: contact@webtoolshop.com
Broken tools & feature ideas
Please use Request a tool or Report an issue so we get steps to reproduce. Submissions go to support@webtoolshop.com when the form backend is configured on the live build.
What to include
For bugs: browser name and version, which tool URL, what you expected, and what happened instead. For new tools: who it is for and an example input/output. Avoid sending passwords or full card numbers by email.
Other inboxes
hello@webtoolshop.com and info@webtoolshop.com may still work; we usually consolidate replies from contact@ or support@ above.
Request a tool
Tell us what free utility you’d like to see next. Submissions go to support@webtoolshop.com (HTTPS). If the form isn’t configured on this build, your mail app opens as a fallback.
Report a tool issue
Something broken, wrong, or confusing? Pick the tool and describe what happened. Reports go to support@webtoolshop.com when the form is configured; otherwise your mail app opens.
