Frequently Asked Questions
Find answers to common questions about A2ZKit tools and features
Are all tools completely free to use?
Yes! All A2ZKit tools are completely free to use. There are no premium plans, no hidden costs, and no signup requirements. We believe quality tools should be accessible to everyone.
Do I need to create an account to use the tools?
No, you don't need to create an account or sign up for anything. All tools work instantly without any registration process.
Is my data safe and private?
Absolutely! Your privacy is our top priority. All tools run locally in your browser, which means your data never leaves your device. We don't collect, store, or transmit any of your personal information. Read our Privacy Policy for more details.
Do the tools work offline?
Most of our tools work completely offline once the page is loaded since they run in your browser. However, you'll need an internet connection to initially access the website.
Can I use these tools for commercial projects?
Yes — you're free to use the tools, and anything you create with them (formatted code, converted files, resized images, and so on), in both personal and commercial work at no cost. What's not permitted is reselling, redistributing, rebranding, or white-labeling A2ZKit itself — for example copying the site, charging others for access to these tools, or bundling them into your own product. In short: use the tools all you want; just don't resell A2ZKit. See our Terms of Service for details.
Can I edit and convert PDFs for free?
Yes. A2ZKit has a full PDF toolkit — merge, split, rotate, delete and reorder pages, add page numbers, watermark, compress, convert PDF to JPG, and convert PDF to an editable Word (.docx) document. Every PDF tool runs entirely in your browser, so your files are never uploaded to a server, and they're all free with no signup.
Can I resize, crop, and convert images here?
Yes. The image tools let you resize, crop, rotate and flip, compress, convert formats (JPG, PNG, WebP), convert iPhone HEIC photos to JPG, view and remove EXIF metadata (including GPS location), make a circle/profile-picture crop, bulk-resize or bulk-rename many images into a ZIP, extract text from images (OCR), and convert images to and from Base64. Like the PDF tools, everything is processed locally in your browser and is completely free.
Do you have code formatters and minifiers?
Yes. A2ZKit includes a JSON formatter, SQL formatter, XML formatter, and minifier/beautifier tools for HTML, CSS, and JavaScript, plus a JSON diff checker, regex tester, and a mock data generator. All formatting happens in your browser — your code is never sent to a server.
Can I save my favorite tools?
Yes. Click the star icon on any tool page to pin it to your favorites. Favorites and your recently used tools appear on the homepage and at the top of the search dialog (press Ctrl+K or Cmd+K). Everything is stored locally in your browser — no account needed.
Can I share a tool with my settings pre-filled?
On many tools, your current options are encoded into the page URL as you work. Copy the address bar (or use the Share button) and anyone opening that link sees the tool set up exactly the way you had it — great for sharing a regex, a color, a cron expression, or converter settings.
Can I send the output of one tool into another?
Yes. Tools that produce text output have a "Send to…" button next to Copy. It hands the result straight to a compatible tool — for example, format JSON and send it to the Base64 encoder, or build a UTM link and send it to the QR code generator. The hand-off happens entirely inside your browser.
How do I report a bug or suggest a new feature?
We'd love to hear from you! Please email us at contact@a2zkit.com with any bug reports, feature suggestions, or feedback.
Are there any usage limits or restrictions?
No, there are no usage limits, daily quotas, or API restrictions. You can use all tools as much as you need, whenever you need them.
What browsers are supported?
A2ZKit works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your preferred browser for the best experience.
Do you have mobile apps?
Currently, A2ZKit is a web-based platform that works great on mobile browsers. We're considering native mobile apps for the future based on user demand.
Can I embed A2ZKit tools on my website?
Currently, tools are not available for embedding. However, you can always link to specific tools. We may consider embeddable widgets in the future.
What makes A2ZKit different from other online tool sites?
A2ZKit focuses on privacy, speed, and user experience. All tools run locally in your browser (no server processing), and everything is completely free — no signup and no upselling.
Do you have an API for developers?
We don't currently offer an API, but it's something we're considering for the future. Most of our tools run client-side, so you might find our open-source code useful for your projects.
Do you display advertisements?
Yes, we use Google AdSense to display advertisements on our website. This helps us keep all tools completely free and accessible to everyone. The advertisements are separate from your tool usage - all tool processing remains local to your browser. You can learn more about our advertising practices in our Privacy Policy.
How does advertising affect my privacy?
Google AdSense may collect data for ad personalization and measurement, but this doesn't affect your tool data which remains completely private and local to your browser. You can opt out of personalized ads through Google Ad Settings. Your tool input and processing results are never shared with advertisers.
Can I use the tools without seeing advertisements?
The tools will still function normally even if you block advertisements using browser extensions or settings. However, we encourage you to consider allowing ads as they help us maintain and improve our free tools. All tool functionality remains completely independent of ad display.
