❓ Frequently Asked Questions

Yes — all 55 tools are 100% free with no limits, no signup, no watermarks and no premium upsells.

Absolutely. Every tool runs entirely in your browser using JavaScript. Your files are never uploaded to any server — except the Link Shortener, which uses the is.gd API to create the short link.

No. Everything works in any modern browser on phone, tablet or computer.

Most tools work fully offline after the page loads. PDF and QR tools load their libraries from a CDN on first use.

Through advertising. We show ads instead of charging you or selling your data.

This website was developed by Malik Anwaar. See the About page for contact details.

Yes! Use the Request a Tool page and tell us what you need — popular requests get built.

Please do! Every tool page has share buttons for WhatsApp, X and Facebook.

Upload two or more PDF files, arrange them in the order you want, and merge them into a single PDF. Everything happens in your browser — your files are never uploaded to any server.

No. Encrypted or password-protected PDFs cannot be processed by the merger. Remove the password protection first, then merge.

Open the PDF Splitter, select your file, and enter the page numbers or page ranges you want. The tool extracts those pages into a new PDF file.

It depends on the file. The compressor rebuilds the PDF's internal object streams, which works well on text and vector-based PDFs. Scanned PDFs made of page images may shrink very little. Results vary from file to file.

The tool extracts selectable text from the PDF. Scanned pages are just images of text, so there is nothing to extract — the tool does not include OCR (optical character recognition).

The Images to PDF tool works with JPG and PNG images, which are embedded directly into the document. For WebP or BMP images, convert them to JPG or PNG first with the Image Converter.

There is no fixed limit — everything runs locally in your browser, so the practical limit is your device's memory. Very large files may be slow on phones or older computers.

No. All PDF processing happens entirely in your browser using JavaScript libraries. Your files never leave your device.

No. Pages are combined or extracted as-is without re-rendering, so text, images and layout stay exactly the same.

It re-encodes your image at an adjustable quality level. Lowering the quality setting produces a smaller file. You can choose JPG or WebP output.

WebP usually produces smaller files at similar visual quality, while JPG works everywhere including older software. If compatibility matters most, pick JPG; if smallest size matters, try WebP.

No — it removes white or light-colored backgrounds, which works best for logos and product photos on plain backgrounds. It is not an AI subject cutout, so it cannot cleanly remove complex backgrounds from portraits.

Yes. The Image Resizer lets you set exact width and height in pixels, with an optional aspect-ratio lock so the image does not get stretched.

It converts between PNG, JPG, WebP and BMP formats.

Enlarging an image can make it look soft, and converting to JPG is lossy, so some detail is discarded. Always keep a copy of your original file before converting.

It generates small favicon-sized images from your uploaded picture, ready to use as a website icon.

No. All image processing happens locally in your browser — your photos never leave your device.

Yes. There are dedicated tools for cropping to a selected area and rotating or flipping images.

It splits your text on whitespace to count words, and also reports characters (with and without spaces), sentences, paragraphs and estimated reading time.

UPPERCASE, lowercase, Title Case, Sentence case and aLtErNaTiNg (alternating case), among others. Paste your text, pick a format, and copy the result.

Base64 converts text or binary data into plain ASCII characters so it can be safely included in URLs, emails, HTML or data URIs. The tool both encodes and decodes.

No. Base64 is an encoding, not encryption — anyone can decode it instantly. Never use it to hide passwords or sensitive information.

It is placeholder text used by designers and developers to fill layouts before the final copy is ready. The generator produces as many paragraphs as you need.

It formats (beautifies) JSON so it is easy to read, and validates it — if your JSON has a syntax error, the tool tells you.

Yes. Once the page has loaded, all text tools run entirely in your browser with no internet connection needed.

No. Everything you type or paste is processed locally in your browser and never transmitted to any server.

Yes — paste the Base64 string into the decoder and it converts it back to the original text.

Enter your date of birth and it calculates your exact age in years, months and days, plus the total number of days you have lived.

No. The BMI Calculator applies the standard weight-and-height formula and shows the general weight category. It is a rough screening estimate, not a medical diagnosis — talk to a health professional about your health.

It estimates your monthly payment, total interest and total payable from the loan amount, interest rate and term you enter, using the standard amortization formula. These are estimates for planning only — not financial advice. Real loans include fees and terms that vary by lender.

The converter uses indicative rates for 12 world currencies and runs entirely in your browser. The rates are indicative, not real-time market rates, so do not use them for trading or large transfers — check your bank or a live rates provider first.

Enter the bill amount and tip percentage, and it calculates the tip and total — including a per-person split for groups.

Enter the original price and the discount percentage, and it shows the sale price and exactly how much you save.

Common tasks like finding X% of a number, what percentage one number is of another, and percentage increase or decrease.

Common measurement categories such as length, weight, temperature, volume, speed and data — pick a category, enter a value, and convert between its units.

No. Every calculation happens locally in your browser; nothing you enter is saved or transmitted.

Yes. The Password Generator uses your browser's cryptographically secure random number generator. Passwords are created locally and never sent anywhere.

A fixed-length digital fingerprint of any text. Even a tiny change in the input produces a completely different hash. It is commonly used to verify that data has not been altered.

No. Hashing is one-way by design — you cannot recover the original text from its hash.

It queries a public geolocation API and returns the approximate city, region, country, ISP and timezone for an IP address or domain. Accuracy is approximate — usually city-level at best, and VPNs, mobile networks or corporate networks can make it wrong.

No. The checker runs client-side heuristics — suspicious top-level domains, IP-address hosts, URL shorteners and similar warning signs. It is a first-pass check only. When in doubt, never enter passwords or payment details.

Some sites block cross-origin header checks from browsers for security reasons. For those sites, the tool cannot read the headers — you can also try a dedicated scanner like securityheaders.com.

HTTP response headers such as Content-Security-Policy and HSTS that protect a website against common attacks. The checker reports which recommended headers a site sends and which are missing.

Like visiting any website, your request goes through the public geolocation API the tool queries. The tool itself does not store or log your lookups.

No — they are helpful checks, not complete protection. Also use unique passwords, turn on two-factor authentication, keep your software updated, and stay cautious with links and attachments.

Pick any color visually and instantly get its HEX and RGB values, ready to copy into your design or code.

Paste a HEX color code into the converter and it shows the equivalent RGB values — and converts RGB back to HEX too.

It calculates the contrast ratio between a text color and a background color, so you can check whether text is readable and accessible.

Higher ratios mean more readable text. The widely used WCAG accessibility guideline recommends at least 4.5:1 for normal body text.

It builds smooth color gradients from the colors you choose and gives you the ready-to-use CSS code to paste into your website.

Design inspiration. The generator produces sets of colors that work well together for websites, graphics or branding ideas.

Yes — HEX and RGB values can be copied to your clipboard with one click.

No. Once loaded, every color tool runs fully in your browser.

The color values are exact, but screens differ in calibration and brightness, so the same code can look slightly different from device to device.

They remove whitespace, line breaks and comments from your code to shrink file size, which helps pages load faster. Paste your code, minify, and copy the result.

Minifiers only strip unnecessary characters — valid code keeps working exactly the same. Still, always test the minified output and keep a copy of your original.

A Universally Unique Identifier — a 128-bit random ID commonly used as database keys, session IDs or unique filenames. The generator creates version 4 (random) UUIDs.

For practical purposes, yes. Random version-4 UUIDs have such an enormous number of possible values that accidental collisions are effectively impossible — but they are random, not cryptographically guaranteed.

It converts Unix timestamps (seconds since 1 January 1970) into human-readable dates and times, and converts dates back into timestamps.

It converts special characters in URLs into %XX format so links stay valid — for example, a space becomes %20. The tool encodes and decodes URLs.

It sends your long URL to the is.gd API, which returns a short link. This is the one tool on the site that contacts an external service — every other tool runs fully in your browser.

is.gd links are intended to last, but they live on is.gd's service, not on this site — so their long-term availability is up to is.gd.

No — except the Link Shortener, which must send the URL to is.gd to create the short link. Minifiers, encoders, the UUID and timestamp tools all run locally in your browser.
