Frequently Asked Questions
Straight answers about cost, privacy and what these tools will and will not do. Questions about a specific tool are on that tool’s own page.
Using the Tools
No. There is no sign-up, no login and no email required. Open a tool and use it.
Nothing. There are no paid tiers, credits or usage quotas. The file size and batch limits shown on each tool are technical limits of running the work inside a browser tab, not a pricing boundary.
Because the processing happens on your own device. A browser tab has a finite amount of memory, and a tool that has to hold several decoded video frames needs far more of it than one formatting a block of JSON. The limit on each page is what that specific tool can handle reliably.
Yes. Every tool is built to work at phone width. Video and audio tools are the slowest on a phone, because the conversion runs on your device rather than on a server.
Privacy and Your Files
For the image, PDF, video, audio, text and code tools, no. Your file is read by the page, processed in the browser and handed back to you. It never travels over the network and we never see it.
Only the ones that genuinely cannot work otherwise: the SEO checkers, which have to fetch the public URL you give them, and the currency converter, which fetches live exchange rates. Those tools say so on their own page. They send the URL or the currency pair — never a file.
No. Results exist only in the open tab. Closing or reloading the page discards them, which is also why there is no file history or cloud storage — there is nothing stored to list.
Your theme choice, your favourite tools and a short list of recently used tools, all in localStorage on your own device. Clearing your browser data removes them. None of it is sent anywhere.
Results and Limitations
It depends on the format and the setting you choose. PNG compression is lossless by nature. JPEG and WebP are lossy, so a lower quality setting means a smaller file and some loss of detail — each tool shows the real before and after sizes so you can judge the trade-off yourself.
Because some conversions genuinely cannot be done honestly in a browser — rendering an Office document to PDF, for example, needs a full office engine. Rather than hand you a file that looks right and is not, those tools tell you plainly that they are not available.
No, and we would rather say so. It resamples the image to a larger pixel grid using bicubic interpolation. That produces a bigger file, not more information than the original contained. It is not AI upscaling.
The formula each one uses is shown on its page, so you can check the arithmetic yourself. They are reliable for planning, but they are not tax or financial advice, and Indian tax rules in particular change between financial years.
Check the formula or method printed on the tool page first — it states the assumptions, which is often the difference. If it is genuinely wrong, it is a bug worth reporting rather than a setting you missed.
