Frequently Asked Questions

Yes. Every tool is free to use, with no hidden charges, no premium tier, and no cap on how many files you convert.

No. There is no sign-up anywhere on the site. Open a tool, choose your file, and it's ready to download.

No. AllToolsHub works in your existing browser — Chrome, Safari, Firefox or Edge — on a phone, tablet or computer. Nothing to install.

Partly. The first time you open a tool, your browser fetches the small engine it needs (for example, the PDF engine for PDF to Image). After that first load, the tool keeps working without an internet connection for the rest of your session. The Image Compressor and JPG/PNG Converter need no download at all and work offline immediately.

No file is ever uploaded. Every tool runs inside your browser, so your document or photo stays on your own device the whole time. See the full Privacy Policy for details.

There's no limit set by AllToolsHub itself, but because everything runs on your device, very large files (hundreds of pages, or very high-resolution scans) depend on your device's available memory. Older phones with limited RAM may struggle with very large files.

If a PDF is a scanned document or a photo of a page, it contains only an image of the text, not real selectable text. AllToolsHub extracts text that already exists inside the PDF — it does not currently perform OCR (optical character recognition) on scanned pages.

The Word to PDF tool uses the standard fonts built into the PDF format, which only cover Latin-script characters. Text in Devanagari and several other non-Latin scripts can't be drawn with those fonts. When this happens, the result panel offers a "print view" link — opening it and choosing "Save as PDF" from your browser's print dialog produces a pixel-accurate copy that keeps every character correctly.

Text and reading order are kept, but images and precise visual styling are simplified. The result is meant to be easy to edit further in Word, not a pixel-perfect clone of the original PDF.

JPG, PNG and WebP. Converting to JPG fills any transparent areas with white, since JPG doesn't support transparency; PNG and WebP keep it.

It searches for the highest JPEG quality that still fits under the size limit you choose (50 KB, 100 KB, 200 KB or 500 KB), so you get the best-looking photo the limit allows. Only if quality alone can't reach the target does it also reduce the image's pixel dimensions.

Web browsers can't decode Apple's HEIC photo format. On an iPhone, go to Settings ▸ Camera ▸ Formats ▸ Most Compatible to save new photos as JPG, or share the photo once (for example, via WhatsApp or email) to get a JPG copy.

They apply the standard published formulas exactly — each tool's FAQ shows which one. But they are illustrations, not advice: the EMI, SIP and FD tools can't know your bank's exact charges, the salary tool can't know your tax situation, and BMI is a screening number, not a diagnosis. Each calculator states its own limits right under the result.

Yes — the site follows your device's light/dark setting automatically, and the moon/sun button in the header lets you override it. Your choice is remembered on your device.

AllToolsHub is a web app that installs like one: open the site in your phone's browser and choose “Add to Home Screen” (or the install prompt when it appears). After that it opens full-screen from its own icon and keeps working offline once loaded.

Yes. The money calculators — EMI, mortgage, compound interest, SIP, FD, tip, discount, profit and loss, VAT and sales tax — do plain arithmetic on the numbers you type and return the answer in the same units. No currency is assumed and nothing is converted, so the figures mean whatever currency you entered. Two tools are country-specific by design and say so on their own pages: the GST Calculator uses India's slab rates, and the Salary/CTC Calculator is built around Indian payroll deductions.

All of them. The site is in English and every tool runs in your own browser, so there is no server location, no regional restriction and no account tied to a country. Dates and numbers are shown in your device's own format. The only exceptions are the two India-specific calculators named above, which are labelled as such.
